Background + +The tzsetup(8) program allows the user to specify the default local +timezone. Based on the selected timezone, tzsetup(8) copies one of the +files from /usr/share/zoneinfo to /etc/localtime. This file actually +controls the conversion. + +II. Problem Description + +Several changes in Daylight Savings Time happened after previous +FreeBSD releases were released that would affect many people who +live in different countries. Because of these changes, the data in +the zoneinfo files need to be updated, and if the local timezone on +the running system is affected, tzsetup(8) needs to be run so the +/etc/localtime is updated. + +III. Impact + +An incorrect time will be displayed on a system configured to use one +of the affected timezones if the /usr/share/zoneinfo and /etc/localtime +files are not updated, and all applications on the system that rely on +the system time, such as cron(8) and syslog(8), will be affected. + +IV. Workaround + +The system administrator can install an updated timezone database from +the misc/zoneinfo port and run tzsetup(8) to get the timezone database +corrected. + +Applications that store and display times in Coordinated Universal Time +(UTC) are not affected. + +V. Solution + +Please note that some third party software, for instance PHP, Ruby, +Java and Perl, may be using different zoneinfo data source, in such +cases these software has to be updated separately. For software +packages that is installed via package collection, they can be +upgraded by doing a `pkg upgrade'. + +Following the instructions in this Errata Notice will update all of +the zoneinfo files to be the same as what was released with FreeBSD +release. + +Perform one of the following: + +1) Upgrade your system to a supported FreeBSD stable or release / security +branch (releng) dated after the correction date.

Background + +The FreeBSD telnet daemon, telnetd(8), implements the server side of the +TELNET virtual terminal protocol. It has been disabled by default in +FreeBSD since August 2001, and due to the lack of cryptographic security +in the TELNET protocol, it is strongly recommended that the SSH protocol +be used instead. The FreeBSD telnet daemon can be enabled via the +/etc/inetd.conf configuration file and the inetd(8) daemon. + +After a user is connected, telnetd executes the login(1) program or a +similar program specified by the -p <loginprog> argument. In order to do +so, it constructs an array of command line arguments which are passed to +execv(3). + +II. Problem Description + +An unexpected sequence of memory allocation failures combined with +insufficient error checking could result in the construction and +execution of an argument sequence that was not intended. + +III. Impact + +An attacker who controls the sequence of memory allocation failures and +success may cause login(1) to run without authentication and may be able +to cause misbehavior of login(1) replacements. + +No practical way of controlling these memory allocation failures is +known at this time. + +IV. Workaround + +No workaround is available, but systems not running the telnet daemon +are not vulnerable. + +Note that the telnet daemon is usually run via inetd, and consequently +will not show up in a process listing unless a connection is currently +active; to determine if it is enabled, run + +$ ps ax | grep telnetd | grep -v grep +$ grep telnetd /etc/inetd.conf | grep -vE '^#' + +If any output is produced, your system may be vulnerable. + +V.

This arranges for the functions ++# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", ++# "posix2time", and "time2posix" to be added to the time conversion library. ++# "tzsetwall" is like "tzset" except that it arranges for local wall clock ++# time (rather than the time specified in the TZ environment variable) ++# to be used. ++# "offtime" is like "gmtime" except that it accepts a second (long) argument ++# that gives an offset to add to the time_t when converting it. ++# "timelocal" is equivalent to "mktime". ++# "timegm" is like "timelocal" except that it turns a struct tm into ++# a time_t using UT (rather than local time as "timelocal" does). ++# "timeoff" is like "timegm" except that it accepts a second (long) argument ++# that gives an offset to use when converting to a time_t. ++# "posix2time" and "time2posix" are described in an included manual page. ++# X3J11's work does not describe any of these functions. ++# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. ++# These functions may well disappear in future releases of the time ++# conversion package. ++# ++# If you don't want functions that were inspired by NetBSD, add ++# -DNETBSD_INSPIRED=0 ++# to the end of the "CFLAGS=" line. Otherwise, the functions ++# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the ++# time library, and if STD_INSPIRED is also defined the functions ++# "posix2time_z" and "time2posix_z" are added as well. ++# The functions ending in "_z" (or "_rz") are like their unsuffixed ++# (or suffixed-by-"_r") counterparts, except with an extra first ++# argument of opaque type timezone_t that specifies the time zone. ++# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. ++# ++# If you want to allocate state structures in localtime, add ++# -DALL_STATE ++# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. ++# ++# If you want an "altzone" variable (a la System V Release 3.1), add ++# -DALTZONE ++# to the end of the "CFLAGS=" line. ++# This variable is not described in X3J11's work. ++# ++# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put ++# out by the National Institute of Standards and Technology ++# which claims to test C and Posix conformance.

This causes "strftime" to always return ++# 53 as a week number (rather than 52 or 53) for those days in January that ++# before the first Monday in January when a "%V" format is used and January 1 ++# falls on a Friday, Saturday, or Sunday. ++ ++CFLAGS= ++ ++# Linker flags.

For Europe/Moscow the invented abbreviation MSM ++ was replaced by +05, whereas MSK and MSD were kept as they are not ++ our invention and are widely used. ++ ++ Changes to zone names ++ ++ Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link. ++ (Thanks to David Massoud.) ++ ++ Changes to code ++ ++ zic no longer generates binary files containing POSIX TZ-like ++ strings that disagree with the local time type after the last ++ explicit transition in the data. This fixes a bug with ++ Africa/Casablanca and Africa/El_Aaiun in some year-2037 time ++ stamps on the reference platform. (Thanks to Alexander Belopolsky ++ for reporting the bug and suggesting a way forward.) ++ ++ If the installed localtime and/or posixrules files are symbolic ++ links, zic now keeps them symbolic links when updating them, for ++ compatibility with platforms like OpenSUSE where other programs ++ configure these files as symlinks. ++ ++ zic now avoids hard linking to symbolic links, avoids some ++ unnecessary mkdir and stat system calls, and uses shorter file ++ names internally. ++ ++ zdump has a new -i option to generate transitions in a ++ more-compact but still human-readable format. This option is ++ experimental, and the output format may change in future versions. ++ (Thanks to Jon Skeet for suggesting that an option was needed, ++ and thanks to Tim Parenti and Chris Rovick for further comments.) ++ ++ Changes to build procedure ++ ++ An experimental distribution format is available, in addition ++ to the traditional format which will continue to be distributed. ++ The new format is a tarball tzdb-VERSION.tar.lz with signature ++ file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory ++ tzdb-VERSION containing the code and data of the traditional ++ two-tarball format, along with extra data that may be useful. ++ (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others ++ for comments about the experimental format.) ++ ++ The release version number is now more accurate in the usual case ++ where releases are built from a Git repository. For example, if ++ 23 commits and some working-file changes have been made since ++ release 2016g, the version number is now something like ++ '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. ++ Official releases uses the same version number format as before, ++ e.g., '2016g'. To support the more-accurate version number, its ++ specification has moved from a line in the Makefile to a new ++ source file 'version'. ++ ++ The experimental distribution contains a file to2050.tzs that ++ contains what should be the output of 'zdump -i -c 2050' on ++ primary zones. If this file is available, 'make check' now checks ++ that zdump generates this output. ++ ++ 'make check_web' now works on Fedora-like distributions. ++ ++ Changes to documentation and commentary ++ ++ tzfile.5 now documents the new restriction on POSIX TZ-like ++ strings that is now implemented by zic. ++ ++ Comments now cite URLs for some 1917-1921 Russian DST decrees. ++ (Thanks to Alexander Belopolsky.) ++ ++ tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J ++ (thanks to Meno Hochschild) and ThreeTen-Extra, and its ++ description of Java 8 has been brought up to date (thanks to ++ Stephen Colebourne). Its description of local time on Mars has ++ been updated to match current practice, and URLs have been updated ++ and some obsolete ones removed. ++ ++ ++Release 2016f - 2016-07-05 16:26:51 +0200 ++ ++ Changes affecting future time stamps ++ ++ The Egyptian government changed its mind on short notice, and ++ Africa/Cairo will not introduce DST starting 2016-07-07 after all. ++ (Thanks to Mina Samuel.) ++ ++ Asia/Novosibirsk switches from +06 to +07 on 2016-07-24 at 02:00. ++ (Thanks to Stepan Golosunov.) ++ ++ Changes to past and future time stamps ++ ++ Asia/Novokuznetsk and Asia/Novosibirsk now use numeric time zone ++ abbreviations instead of invented ones. ++ ++ Changes affecting past time stamps ++ ++ Europe/Minsk's 1992-03-29 spring-forward transition was at 02:00 not 00:00. ++ (Thanks to Stepan Golosunov.) ++ ++ ++Release 2016e - 2016-06-14 08:46:16 -0700 ++ ++ Changes affecting future time stamps ++ ++ Africa/Cairo observes DST in 2016 from July 7 to the end of October. ++ Guess October 27 and 24:00 transitions.

When localtime_rz is ++ not available, zdump now uses localtime_r and tzset if available, ++ as this is a bit cleaner and faster than plain localtime. Compile ++ with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system ++ lacks these two functions. ++ ++ If THREAD_SAFE is defined to 1, the tz library is now thread-safe. ++ Although not needed for tz's own applications, which are single-threaded, ++ this supports POSIX better if the tz library is used in multithreaded apps. ++ ++ Some crashes have been fixed when zdump or the tz library is given ++ invalid or outlandish input. ++ ++ The tz library no longer mishandles leap seconds on platforms with ++ unsigned time_t in time zones that lack ordinary transitions after 1970. ++ ++ The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not ++ already defined, to make it easier to configure on common platforms. ++ Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. ++ ++ Unless the new macro UNINIT_TRAP is defined to 1, the tz code now ++ assumes that reading uninitialized memory yields garbage values ++ but does not cause other problems such as traps. ++ ++ If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now ++ more likely to guess right for ambiguous time stamps near ++ transitions where tm_isdst does not change. ++ ++ If HAVE_STRFTIME_L is defined to 1, the tz library now defines ++ strftime_l for compatibility with recent versions of POSIX. ++ Only the C locale is supported, though. HAVE_STRFTIME_L defaults ++ to 1 on recent POSIX versions, and to 0 otherwise. ++ ++ tzselect -c now uses a hybrid distance measure that works better ++ in Africa. (Thanks to Alan Barrett for noting the problem.) ++ ++ The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, ++ or when time_tz is defined. ++ ++ When HAVE_UTMPX_H is set the 'date' command now builds on systems ++ whose <utmpx.h> file does not define WTMPX_FILE, and when setting ++ the date it updates the wtmpx file if _PATH_WTMPX is defined. ++ This affects GNU/Linux and similar systems. ++ ++ For easier maintenance later, some C code has been simplified, ++ some lint has been removed, and the code has been tweaked so that ++ plain 'make' is more likely to work. ++ ++ The C type 'bool' is now used for boolean values, instead of 'int'. ++ ++ The long-obsolete LOCALE_HOME code has been removed. ++ ++ The long-obsolete 'gtime' function has been removed. ++ ++ Changes affecting build procedure ++ ++ 'zdump' no longer links in ialloc.o, as it's not needed. ++ ++ 'make check_time_t_alternatives' no longer assumes GNU diff. ++ ++ Changes affecting distribution tarballs ++ ++ The files checktab.awk and zoneinfo2tdf.pl are now distributed in ++ the tzdata tarball instead of the tzcode tarball, since they help ++ maintain the data. The NEWS and Theory files are now also ++ distributed in the tzdata tarball, as they're relevant for data. ++ (Thanks to Alan Barrett for pointing this out.) Also, the ++ leapseconds.awk file is no longer distributed in the tzcode ++ tarball, since it belongs in the tzdata tarball (where 2014f ++ inadvertently also distributed it). ++ ++ Changes affecting documentation and commentary ++ ++ A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for ++ suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms ++ for debugging it.) ++ ++ The man pages have been updated to use function prototypes, ++ to document thread-safe variants like localtime_r, and to document ++ the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and ++ mktime_z. ++ ++ The fields in Link lines have been renamed to be more descriptive ++ and more like the parameters of 'ln'. LINK-FROM has become TARGET, ++ and LINK-TO has become LINK-NAME. ++ ++ tz-link.htm mentions the IETF's tzdist working group; Windows ++ Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. ++ ++ Some broken URLs have been fixed in the commentary. (Thanks to ++ Lester Caine.) ++ ++ Commentary about Philippines DST has been updated, and commentary ++ on pre-1970 time in India has been added. ++ ++ ++Release 2014f - 2014-08-05 17:42:36 -0700 ++ ++ Changes affecting future time stamps ++ ++ Russia will subtract an hour from most of its time zones on 2014-10-26 ++ at 02:00 local time. (Thanks to Alexander Krivenyshev.) ++ There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky ++ Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug ++ (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast ++ (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic ++ (Europe/Samara) are not changing their clocks. The changed zones are ++ Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, ++ Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, ++ Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, ++ Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours ++ subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, ++ but not its UTC offset. Two zones are added: Asia/Chita (split ++ from Asia/Yakutsk, and also with two hours subtracted) and ++ Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour ++ subtracted). (Thanks to Tim Parenti for much of the above.) ++ ++ Changes affecting time zone abbreviations ++ ++ Australian eastern time zone abbreviations are now AEST/AEDT not EST, ++ and similarly for the other Australian zones. That is, for eastern ++ standard and daylight saving time the abbreviations are AEST and AEDT ++ instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT, ++ and AWST/AWDT are now used instead of the former CST, CWST, and WST. ++ This change does not affect UTC offsets, only time zone abbreviations. ++ (Thanks to Rich Tibbett and many others.) ++ ++ Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UT +07) ++ effective 2014-10-26 at 02:00 local time. ++ ++ The time zone abbreviation for Xinjiang Time (observed in Ürümqi) ++ has been changed from URUT to XJT. (Thanks to Luther Ma.) ++ ++ Prefer MSK/MSD for Moscow time in Russia, even in other cities. ++ Similarly, prefer EET/EEST for eastern European time in Russia. ++ ++ Change time zone abbreviations in (western) Samoa to use "ST" and ++ "DT" suffixes, as this is more likely to match common practice. ++ Prefix "W" to (western) Samoa time when its standard-time offset ++ disagrees with that of American Samoa. ++ ++ America/Metlakatla now uses PST, not MeST, to abbreviate its time zone. ++ ++ Time zone abbreviations have been updated for Japan's two time ++ zones used 1896-1937. JWST now stands for Western Standard ++ Time, and JCST for Central Standard Time (formerly this was CJT). ++ These abbreviations are now used for time in Korea, Taiwan, ++ and Sakhalin while controlled by Japan. ++ ++ Changes affecting past time stamps ++ ++ China's five zones have been simplified to two, since the post-1970 ++ differences in the other three seem to have been imaginary. The ++ zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been ++ removed; backwards-compatibility links still work, albeit with ++ different behaviors for time stamps before May 1980. Asia/Urumqi's ++ 1980 transition to UT +08 has been removed, so that it is now at ++ +06 and not +08. (Thanks to Luther Ma and to Alois Treindl; ++ Treindl sent helpful translations of two papers by Guo Qingsheng.) ++ ++ Some zones have been turned into links, when they differed from existing ++ zones only for older UTC offsets where data entries were likely invented. ++ These changes affect UTC offsets in pre-1970 time stamps only. This is ++ similar to the change in release 2013e, except this time for western ++ Africa. The affected zones are: Africa/Bamako, Africa/Banjul, ++ Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, ++ Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and ++ Atlantic/St_Helena. This also affects the backwards-compatibility ++ link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, ++ Tim Parenti, and David Patte for reporting problems in earlier ++ versions of this change.) ++ ++ Asia/Shanghai's pre-standard-time UT offset has been changed from ++ 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its ++ transition to standard time has been changed from 1928 to 1901. ++ ++ Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, ++ then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. ++ In 1946 it observed DST from 05-15 through 09-30; in 1947 ++ from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. ++ (Thanks to Yu-Cheng Chuang.) ++ ++ Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. ++ ++ Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not ++ 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) ++ ++ Pacific/Pago_Pago has been changed from UT -11:30 to -11 for the ++ period from 1911 to 1950. ++ ++ Pacific/Chatham has been changed to New Zealand standard time plus ++ 45 minutes for the period before 1957, reflecting a 1956 remark in ++ the New Zealand parliament. ++ ++ Europe/Budapest has several pre-1946 corrections: in 1918 the transition ++ out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in ++ 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 ++ not 04-06 at 02:00; and there was no DST in 1920. ++ ++ Africa/Accra is now assumed to have observed DST from 1920 through 1935. ++ ++ Time in Russia before 1927 or so has been corrected by a few seconds in ++ the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, ++ Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and ++ Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 ++ point. (Thanks to Vladimir Karpinsky for the Moscow changes.) ++ ++ Changes affecting data format ++ ++ A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. ++ The new file's extended format allows multiple country codes per zone. ++ The older file is still installed but is deprecated; its format is ++ not changing and it will still be distributed for a while, but new ++ applications should use the new file. ++ ++ The new file format simplifies maintenance of obscure locations. ++ To test this, it adds coverage for the Crozet Islands and the ++ Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) ++ ++ The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. ++ It is still ASCII now, but commentary about the switch has been added. ++ The new file 'zone1970.tab' already uses UTF-8. ++ ++ Changes affecting code ++ ++ 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE ++ is defined. (Thanks to Elliott Hughes for reporting the problem.) ++ ++ 'zic' no longer mishandles input when ignoring case in locales that ++ are not compatible with English, e.g., unibyte Turkish locales when ++ compiled with HAVE_GETTEXT. ++ ++ Error diagnostics of 'zic' and 'yearistype' have been reworded so that ++ they no longer use ASCII '-' as if it were a dash. ++ ++ 'zic' now rejects output file names that contain '.' or '..' components. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ 'zic -v' now warns about output file names that do not follow ++ POSIX rules, or that contain a digit or '.'. (Thanks to Arthur ++ David Olson for starting the ball rolling on this.) ++ ++ Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. ++ ++ Changes affecting build procedure ++ ++ 'zic' no longer links in localtime.o and asctime.o, as they're not needed. ++ (Thanks to John Cochran.) ++ ++ Changes affecting documentation and commentary ++ ++ The 'Theory' file documents legacy names, the longstanding ++ exceptions to the POSIX-inspired file name rules. ++ ++ The 'zic' documentation clarifies the role of time types when ++ interpreting dates. (Thanks to Arthur David Olson.) ++ ++ Documentation and commentary now prefer UTF-8 to US-ASCII, ++ allowing the use of proper accents in foreign words and names. ++ Code and data have not changed because of this. (Thanks to ++ Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug ++ this.) ++ ++ Non-HTML documentation and commentary now use plain-text URLs instead of ++ HTML insertions, and are more consistent about bracketing URLs when they ++ are not already surrounded by white space. (Thanks to suggestions by ++ Steffen Nurpmeso.) ++ ++ There is new commentary about Xujiahui Observatory, the five time-zone ++ project in China from 1918 to 1949, timekeeping in Japanese-occupied ++ Shanghai, and Tibet Time in the 1950s. The sharp-eyed can spot the ++ warlord Jin Shuren in the data. ++ ++ Commentary about the coverage of each Russian zone has been standardized. ++ (Thanks to Tim Parenti). ++ ++ There is new commentary about contemporary timekeeping in Ethiopia. ++ ++ Obsolete comments about a 2007 proposal for DST in Kuwait has been removed. ++ ++ There is new commentary about time in Poland in 1919. ++ ++ Proper credit has been given to DST inventor George Vernon Hudson. ++ ++ Commentary about time in Metlakatla, AK and Resolute, NU has been ++ improved, with a new source for the former. ++ ++ In zone.tab, Pacific/Easter no longer mentions Salas y Gómez, as it ++ is uninhabited. ++ ++ Commentary about permanent Antarctic bases has been updated. ++ ++ Several typos have been corrected. (Thanks to Tim Parenti for ++ contributing some of these fixes.) ++ ++ tz-link.htm now mentions the JavaScript libraries Moment Timezone, ++ TimezoneJS.Date, Walltime-js, and Timezone. (Thanks to a heads-up ++ from Matt Johnson.) Also, it mentions the Go 'latlong' package. ++ (Thanks to a heads-up from Dirkjan Ochtman.) ++ ++ The files usno1988, usno1989, usno1989a, usno1995, usno1997, and usno1998 ++ have been removed. These obsolescent US Naval Observatory entries were no ++ longer helpful for maintenance. (Thanks to Tim Parenti for the suggestion.) ++ ++ ++Release 2014e - 2014-06-12 21:53:52 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00. ++ (Thanks to Imed Chihi.) Guess that from 2015 on Egypt will temporarily ++ switch to standard time at 24:00 the last Thursday before Ramadan, and ++ back to DST at 00:00 the first Friday after Ramadan. ++ ++ Similarly, Morocco's are June 28 at 03:00 and August 2 at 02:00. (Thanks ++ to Milamber Space Network.) Guess that from 2015 on Morocco will ++ temporarily switch to standard time at 03:00 the last Saturday before ++ Ramadan, and back to DST at 02:00 the first Saturday after Ramadan. ++ ++ Changes affecting past time stamps ++ ++ The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of ++ "MSD" for Moscow's double daylight time in summer 1921. Also, a typo ++ "VLASST" has been repaired to be "VLAST" for Vladivostok summer time ++ in 1991. (Thanks to Hank W. for reporting the problems.) ++ ++ Changes affecting commentary ++ ++ tz-link.htm now cites RFC 7265 for jCal, mentions PTP and the ++ draft CalDAV extension, updates URLs for TSP, TZInfo, IATA, and ++ removes stale pointers to World Time Explorer and WORLDTIME. ++ ++ ++Release 2014d - 2014-05-27 21:34:40 -0700 ++ ++ Changes affecting code ++ ++ zic no longer generates files containing time stamps before the Big Bang. ++ This works around GNOME bug 730332 ++ <https://bugzilla.gnome.org/show_bug.cgi?id=730332>. ++ (Thanks to Leonardo Chiquitto for reporting the bug, and to ++ Arthur David Olson and James Cloos for suggesting improvements to the fix.) ++ ++ Changes affecting documentation ++ ++ tz-link.htm now mentions GNOME. ++ ++ ++Release 2014c - 2014-05-13 07:44:13 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Egypt observes DST starting 2014-05-15 at 24:00. ++ (Thanks to Ahmad El-Dardiry and Gunther Vermier.) ++ Details have not been announced, except that DST will not be observed ++ during Ramadan.

For now, guess that ++ Fiji will continue to spring forward the Sunday before the fourth ++ Monday in October. ++ ++ Changes affecting current and future time zone abbreviations ++ ++ Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian ++ time zone abbreviations since 1932. (Thanks to George Ziegler, ++ Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and ++ Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, ++ Asia/Makassar, and Asia/Pontianak. ++ ++ Use ART (UT -03, standard time), rather than WARST (also -03, but ++ daylight saving time) for San Luis, Argentina since 2009. ++ ++ Changes affecting Godthåb time stamps after 2037 if version mismatch ++ ++ Allow POSIX-like TZ strings where the transition time's hour can ++ range from -167 through 167, instead of the POSIX-required 0 ++ through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the ++ new Fiji rules. This is a more-compact way to represent ++ far-future time stamps for America/Godthab, America/Santiago, ++ Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, ++ Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by ++ this change. (Derived from a suggestion by Arthur David Olson.) ++ ++ Allow POSIX-like TZ strings where daylight saving time is in ++ effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western ++ Argentina Summer Time all year. This supports a more-compact way ++ to represent the 2013d data for America/Argentina/San_Luis. ++ Because of the change for San Luis noted above this change does not ++ affect the current data. (Thanks to Andrew Main (Zefram) for ++ suggestions that improved this change.) ++ ++ Where these two TZ changes take effect, there is a minor extension ++ to the tz file format in that it allows new values for the ++ embedded TZ-format string, and the tz file format version number ++ has therefore been increased from 2 to 3 as a precaution. ++ Version-2-based client code should continue to work as before for ++ all time stamps before 2038. Existing version-2-based client code ++ (tzcode, GNU/Linux, Solaris) has been tested on version-3-format ++ files, and typically works in practice even for time stamps after ++ 2037; the only known exception is America/Godthab. ++ ++ Changes affecting time stamps before 1970 ++ ++ Pacific/Johnston is now a link to Pacific/Honolulu. This corrects ++ some errors before 1947. ++ ++ Some zones have been turned into links, when they differ from existing ++ zones only in older data entries that were likely invented or that ++ differ only in LMT or transitions from LMT. These changes affect ++ only time stamps before 1943. The affected zones are: ++ Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, ++ America/Grenada, America/Guadeloupe, America/Marigot, ++ America/Montserrat, America/St_Barthelemy, America/St_Kitts, ++ America/St_Lucia, America/St_Thomas, America/St_Vincent, ++ America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for ++ confirming that the old Europe/Vaduz zone was wrong and the new ++ link is better for WWII-era times.) ++ ++ Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects ++ America/Cayman, America/Jamaica and America/Grand_Turk time stamps ++ from 1890 to 1912. ++ ++ Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. ++ This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks ++ to Alois Treindl). ++ ++ Change the date of the circa-1850 Zurich transition from 1849-09-12 ++ to 1853-07-16, overriding Shanks with data from Messerli about ++ postal and telegraph time in Switzerland. ++ ++ Changes affecting time zone abbreviations before 1970 ++ ++ For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, ++ as Jakarta was called Batavia back then. ++ ++ Changes affecting API ++ ++ The 'zic' command now outputs a dummy transition when far-future ++ data can't be summarized using a TZ string, and uses a 402-year ++ window rather than a 400-year window. For the current data, this ++ affects only the Asia/Tehran file. It does not affect any of the ++ time stamps that this file represents, so zdump outputs the same ++ information as before. (Thanks to Andrew Main (Zefram).) ++ ++ The 'date' command has a new '-r' option, which lets you specify ++ the integer time to display, a la FreeBSD. ++ ++ The 'tzselect' command has two new options '-c' and '-n', which lets you ++ select a zone based on latitude and longitude. ++ ++ The 'zic' command's '-v' option now warns about constructs that ++ require the new version-3 binary file format. (Thanks to Arthur ++ David Olson for the suggestion.) ++ ++ Support for floating-point time_t has been removed. ++ It was always dicey, and POSIX no longer requires it. ++ (Thanks to Eric Blake for suggesting to the POSIX committee to ++ remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy ++ Heninger, Arthur David Olson, and Alois Treindl, for reporting ++ bugs and elucidating some of the corners of the old floating-point ++ implementation.) ++ ++ The signatures of 'offtime', 'timeoff', and 'gtime' have been ++ changed back to the old practice of using 'long' to represent UT ++ offsets. This had been inadvertently and mistakenly changed to ++ 'int_fast32_t'. (Thanks to Christos Zoulas.) ++ ++ The code avoids undefined behavior on integer overflow in some ++ more places, including gmtime, localtime, mktime and zdump. ++ ++ Changes affecting the zdump utility ++ ++ zdump now outputs "UT" when referring to Universal Time, not "UTC". ++ "UTC" does not make sense for time stamps that predate the introduction ++ of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen ++ for clarifying UT vs UTC.) ++ ++ Data changes affecting behavior of tzselect and similar programs ++ ++ Country code BQ is now called the more-common name "Caribbean Netherlands" ++ rather than the more-official "Bonaire, St Eustatius & Saba". ++ ++ Remove from zone.tab the names America/Montreal, America/Shiprock, ++ and Antarctica/South_Pole, as they are equivalent to existing ++ same-country-code zones for post-1970 time stamps. The data entries for ++ these names are unchanged, so the names continue to work as before. ++ ++ Changes affecting code internals ++ ++ zic -c now runs way faster on 64-bit hosts when given large numbers. ++ ++ zic now uses vfprintf to avoid allocating and freeing some memory. ++ ++ tzselect now computes the list of continents from the data, ++ rather than have it hard-coded. ++ ++ Minor changes pacify GCC 4.7.3 and GCC 4.8.1. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is now generated automatically from a ++ new file 'leap-seconds.list', which is a copy of ++ <ftp://time.nist.gov/pub/leap-seconds.list>. ++ A new source file 'leapseconds.awk' implements this. ++ The goal is simplification of the future maintenance of 'leapseconds'. ++ ++ When building the 'posix' or 'right' subdirectories, if the ++ subdirectory would be a copy of the default subdirectory, it is ++ now made a symbolic link if that is supported. This saves about ++ 2 MB of file system space. ++ ++ The links America/Shiprock and Antarctica/South_Pole have been ++ moved to the 'backward' file. This affects only nondefault builds ++ that omit 'backward'. ++ ++ Changes affecting version-control only ++ ++ .gitignore now ignores 'date'. ++ ++ Changes affecting documentation and commentary ++ ++ Changes to the 'tzfile' man page ++ ++ It now mentions that the binary file format may be extended in ++ future versions by appending data. ++ ++ It now refers to the 'zdump' and 'zic' man pages. ++ ++ Changes to the 'zic' man page ++ ++ It lists conditions that elicit a warning with '-v'. ++ ++ It says that the behavior is unspecified when duplicate names ++ are given, or if the source of one link is the target of another. ++ ++ Its examples are updated to match the latest data. ++ ++ The definition of white space has been clarified slightly. ++ (Thanks to Michael Deckers.) ++ ++ Changes to the 'Theory' file ++ ++ There is a new section about the accuracy of the tz database, ++ describing the many ways that errors can creep in, and ++ explaining why so many of the pre-1970 time stamps are wrong or ++ misleading (thanks to Steve Allen, Lester Caine, and Garrett ++ Wollman for discussions that contributed to this). ++ ++ The 'Theory' file describes LMT better (this follows a ++ suggestion by Guy Harris). ++ ++ It refers to the 2013 edition of POSIX rather than the 2004 edition. ++ ++ It's mentioned that excluding 'backward' should not affect the ++ other data, and it suggests at least one zone.tab name per ++ inhabited country (thanks to Stephen Colebourne). ++ ++ Some longstanding restrictions on names are documented, e.g., ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ ++ It gives more reasons for the 1970 cutoff. ++ ++ It now mentions which time_t variants are supported, such as ++ signed integer time_t. (Thanks to Paul Goyette for reporting ++ typos in an experimental version of this change.) ++ ++ (Thanks to Philip Newton for correcting typos in these changes.) ++ ++ Documentation and commentary is more careful to distinguish UT in ++ general from UTC in particular. (Thanks to Steve Allen.) ++ ++ Add a better source for the Zurich 1894 transition. ++ (Thanks to Pierre-Yves Berger.) ++ ++ Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.) ++ ++ ++Release 2013d - 2013-07-05 07:38:01 -0700 ++ ++ Changes affecting future time stamps: ++ ++ Morocco's midsummer transitions this year are July 7 and August 10, ++ not July 9 and August 8. (Thanks to Andrew Paprocki.) ++ ++ Israel now falls back on the last Sunday of October. ++ (Thanks to Ephraim Silverberg.) ++ ++ Changes affecting past time stamps: ++ ++ Specify Jerusalem's location more precisely; this changes the pre-1880 ++ times by 2 s. ++ ++ Changing affecting metadata only: ++ ++ Fix typos in the entries for country codes BQ and SX. ++ ++ Changes affecting code: ++ ++ Rework the code to fix a bug with handling Australia/Macquarie on ++ 32-bit hosts (thanks to Arthur David Olson). ++ ++ Port to platforms like NetBSD, where time_t can be wider than long. ++ ++ Add support for testing time_t types other than the system's. ++ Run 'make check_time_t_alternatives' to try this out. ++ Currently, the tests fail for unsigned time_t; ++ this should get fixed at some point. ++ ++ Changes affecting documentation and commentary: ++ ++ Deemphasize the significance of national borders. ++ ++ Update the zdump man page. ++ ++ Remove obsolete NOID comment (thanks to Denis Excoffier). ++ ++ Update several URLs and comments in the web pages. ++ ++ Spelling fixes (thanks to Kevin Lyda and Jonathan Leffler). ++ ++ Update URL for CLDR Zone->Tzid table (thanks to Yoshito Umaoka). ++ ++ ++Release 2013c - 2013-04-19 16:17:40 -0700 ++ ++ Changes affecting current and future time stamps: ++ ++ Palestine observed DST starting March 29, 2013.

Since Mar 11 (the old start ++ date, as listed in 2012a) is just a little over a week away, this ++ change is urgent. ++ ++ Less importantly, an excess tab in one of the changes in zone.tab ++ in 2012a has been removed. ++ ++ ++Release 2012a - 2012-03-01 18:28:10 +0700 ++ ++ The changes in tzcode2012a (compared to the previous version, 2011i) ++ are entirely to the README and tz-art.htm and tz-link.htm files, if ++ none of those concern you, you can ignore the code update.

Second, the Pridnestrovian Moldavian Republic ++ (Europe/Tiraspol) decided not to split from the rest of Moldova after ++ all, and consequently that zone has been removed (again) and reinstated ++ in the "backward" file as a link to Europe/Chisinau. And third, the ++ end date for Fiji's summer time this summer was moved forward from the ++ earlier planned Feb 26, to Jan 22. ++ ++ Apart from that, Moldova (MD) returns to a single entry in zone.tab ++ (and the incorrect syntax that was in the 2011m version of that file ++ is so fixed - it would have been fixed in a different way had this ++ change not happened - that's the "missing" sccs version id). ++ ++ ++Release data2011m - 2011-10-24 21:42:16 +0700 ++ ++ In particular, the typos in comments in the data (2011-11-17 should have ++ been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that ++ Tim Parenti noted) have been fixed, and the change for Ukraine has been ++ made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to ++ Tim Parenti, and also Denys Gavrysh) ++ ++ In addition, I added Europe/Tiraspol to zone.tab. ++ ++ This time, all the files have new version numbers...

The text has been ++adapted and reformatted for the purposes of this file. ++ ++Traditionally a release R consists of a pair of tarball files, ++tzcodeR.tar.gz and tzdataR.tar.gz. However, some releases (e.g., ++code2010a, data2012c) consist of just one or the other tarball, and a ++few (e.g., code2012c-data2012d) have tarballs with mixed version ++numbers. Recent releases also come in an experimental format ++consisting of a single tarball tzdb-R.tar.lz with extra data. ++ ++Release time stamps are taken from the release's commit (for newer, ++Git-based releases), from the newest file in the tarball (for older ++releases, where this info is available) or from the email announcing ++the release (if all else fails; these are marked with a time zone of ++-0000 and an "is missing!" comment). ++ ++Earlier versions of the code and data were not announced on the tz ++list and are not summarized here. ++ ++This file is in the public domain. ++ ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/README.orig ++++ contrib/tzdata/README +@@ -0,0 +1,71 @@ ++README for the tz distribution ++ ++"What time is it?" -- Richard Deacon as The King ++"Any time you want it to be." -- Frank Baxter as The Scientist ++ (from the Bell System film "About Time") ++ ++The Time Zone Database (often called tz or zoneinfo) contains code and ++data that represent the history of local time for many representative ++locations around the globe.

To represent this ++data, the world is partitioned into regions whose clocks all agree ++about time stamps that occur after the somewhat-arbitrary cutoff point ++of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region, ++the database records all known clock transitions, and labels the region ++with a notable location. Although 1970 is a somewhat-arbitrary ++cutoff, there are significant challenges to moving the cutoff earlier ++even by a decade or two, due to the wide variety of local practices ++before computer timekeeping became prevalent. ++ ++Clock transitions before 1970 are recorded for each such location, ++because most systems support time stamps before 1970 and could ++misbehave if data entries were omitted for pre-1970 transitions. ++However, the database is not designed for and does not suffice for ++applications requiring accurate handling of all past times everywhere, ++as it would take far too much effort and guesswork to record all ++details of pre-1970 civil timekeeping. ++ ++As described below, reference source code for using the tz database is ++also available. The tz code is upwards compatible with POSIX, an ++international standard for UNIX-like systems. As of this writing, the ++current edition of POSIX is: ++ ++ The Open Group Base Specifications Issue 7 ++ IEEE Std 1003.1, 2013 Edition ++ <http://pubs.opengroup.org/onlinepubs/9699919799/> ++ ++ ++ ++----- Names of time zone rules ----- ++ ++Each of the database's time zone rules has a unique name. ++Inexperienced users are not expected to select these names unaided. ++Distributors should provide documentation and/or a simple selection ++interface that explains the names; for one example, see the 'tzselect' ++program in the tz code. The Unicode Common Locale Data Repository ++<http://cldr.unicode.org/> contains data that may be useful for other ++selection interfaces. ++ ++The time zone rule naming conventions attempt to strike a balance ++among the following goals: ++ ++ * Uniquely identify every region where clocks have agreed since 1970. ++ This is essential for the intended use: static clocks keeping local ++ civil time. ++ ++ * Indicate to experts where that region is. ++ ++ * Be robust in the presence of political changes. For example, names ++ of countries are ordinarily not used, to avoid incompatibilities ++ when countries change their name (e.g. Zaire->Congo) or when ++ locations change countries (e.g. Hong Kong from UK colony to ++ China). ++ ++ * Be portable to a wide variety of implementations. ++ ++ * Use a consistent naming conventions over the entire world. ++ ++Names normally have the form AREA/LOCATION, where AREA is the name ++of a continent or ocean, and LOCATION is the name of a specific ++location within that region. North and South America share the same ++area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York', ++and 'Pacific/Honolulu'. ++ ++Here are the general rules used for choosing location names, ++in decreasing order of importance: ++ ++ Use only valid POSIX file name components (i.e., the parts of ++ names other than '/'). Do not use the file name ++ components '.' and '..'. Within a file name component, ++ use only ASCII letters, '.', '-' and '_'. Do not use ++ digits, as that might create an ambiguity with POSIX ++ TZ strings. A file name component must not exceed 14 ++ characters or start with '-'. E.g., prefer 'Brunei' ++ to 'Bandar_Seri_Begawan'. Exceptions: see the discussion ++ of legacy names below. ++ A name must not be empty, or contain '//', or start or end with '/'. ++ Do not use names that differ only in case. Although the reference ++ implementation is case-sensitive, some other implementations ++ are not, and they would mishandle names differing only in case. ++ If one name A is an initial prefix of another name AB (ignoring case), ++ then B must not start with '/', as a regular file cannot have ++ the same name as a directory in POSIX. For example, ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ Uninhabited regions like the North Pole and Bouvet Island ++ do not need locations, since local time is not defined there. ++ There should typically be at least one name for each ISO 3166-1 ++ officially assigned two-letter code for an inhabited country ++ or territory. ++ If all the clocks in a region have agreed since 1970, ++ don't bother to include more than one location ++ even if subregions' clocks disagreed before 1970. ++ Otherwise these tables would become annoyingly large. ++ If a name is ambiguous, use a less ambiguous alternative; ++ e.g. many cities are named San José and Georgetown, so ++ prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'. ++ Keep locations compact. Use cities or small islands, not countries ++ or regions, so that any future time zone changes do not split ++ locations into different time zones. E.g. prefer 'Paris' ++ to 'France', since France has had multiple time zones. ++ Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and ++ prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'. ++ The POSIX file name restrictions encourage this rule. ++ Use the most populous among locations in a zone, ++ e.g. prefer 'Shanghai' to 'Beijing'. Among locations with ++ similar populations, pick the best-known location, ++ e.g. prefer 'Rome' to 'Milan'. ++ Use the singular form, e.g. prefer 'Canary' to 'Canaries'. ++ Omit common suffixes like '_Islands' and '_City', unless that ++ would lead to ambiguity. E.g. prefer 'Cayman' to ++ 'Cayman_Islands' and 'Guatemala' to 'Guatemala_City', ++ but prefer 'Mexico_City' to 'Mexico' because the country ++ of Mexico has several time zones. ++ Use '_' to represent a space. ++ Omit '.' from abbreviations in names, e.g. prefer 'St_Helena' ++ to 'St._Helena'. ++ Do not change established names if they only marginally ++ violate the above rules. For example, don't change ++ the existing name 'Rome' to 'Milan' merely because ++ Milan's population has grown to be somewhat greater ++ than Rome's. ++ If a name is changed, put its old spelling in the 'backward' file. ++ This means old spellings will continue to work. ++ ++The file 'zone1970.tab' lists geographical locations used to name time ++zone rules. It is intended to be an exhaustive list of names for ++geographic regions as described above; this is a subset of the names ++in the data. Although a 'zone1970.tab' location's longitude ++corresponds to its LMT offset with one hour for every 15 degrees east ++longitude, this relationship is not exact. ++ ++Older versions of this package used a different naming scheme, ++and these older names are still supported. ++See the file 'backward' for most of these older names ++(e.g., 'US/Eastern' instead of 'America/New_York'). ++The other old-fashioned names still supported are ++'WET', 'CET', 'MET', and 'EET' (see the file 'europe'). ++ ++Older versions of this package defined legacy names that are ++incompatible with the first rule of location names, but which are ++still supported. These legacy names are mostly defined in the file ++'etcetera'. Also, the file 'backward' defines the legacy names ++'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file ++'northamerica' defines the legacy names 'EST5EDT', 'CST6CDT', ++'MST7MDT', and 'PST8PDT'. ++ ++Excluding 'backward' should not affect the other data. If ++'backward' is excluded, excluding 'etcetera' should not affect the ++remaining data. ++ ++ ++----- Time zone abbreviations ----- ++ ++When this package is installed, it generates time zone abbreviations ++like 'EST' to be compatible with human tradition and POSIX. ++Here are the general rules used for choosing time zone abbreviations, ++in decreasing order of importance: ++ ++ Use three or more characters that are ASCII alphanumerics or '+' or '-'. ++ Previous editions of this database also used characters like ++ ' ' and '?', but these characters have a special meaning to ++ the shell and cause commands like ++ set `date` ++ to have unexpected effects. ++ Previous editions of this rule required upper-case letters, ++ but the Congressman who introduced Chamorro Standard Time ++ preferred "ChST", so lower-case letters are now allowed. ++ Also, POSIX from 2001 on relaxed the rule to allow '-', '+', ++ and alphanumeric characters from the portable character set ++ in the current locale. In practice ASCII alphanumerics and ++ '+' and '-' are safe in all locales. ++ ++ In other words, in the C locale the POSIX extended regular ++ expression [-+[:alnum:]]{3,} should match the abbreviation. ++ This guarantees that all abbreviations could have been ++ specified by a POSIX TZ string. ++ ++ Use abbreviations that are in common use among English-speakers, ++ e.g. 'EST' for Eastern Standard Time in North America. ++ We assume that applications translate them to other languages ++ as part of the normal localization process; for example, ++ a French application might translate 'EST' to 'HNE'. ++ ++ For zones whose times are taken from a city's longitude, use the ++ traditional xMT notation, e.g. 'PMT' for Paris Mean Time. ++ The only name like this in current use is 'GMT'. ++ ++ Use 'LMT' for local mean time of locations before the introduction ++ of standard time; see "Scope of the tz database". ++ ++ If there is no common English abbreviation, use numeric offsets like ++ -05 and +0830 that are generated by zic's %z notation. ++ ++ [The remaining guidelines predate the introduction of %z. ++ They are problematic as they mean tz data entries invent ++ notation rather than record it. These guidelines are now ++ deprecated and the plan is to gradually move to %z for ++ inhabited locations and to "-00" for uninhabited locations.] ++ ++ If there is no common English abbreviation, abbreviate the English ++ translation of the usual phrase used by native speakers. ++ If this is not available or is a phrase mentioning the country ++ (e.g. "Cape Verde Time"), then: ++ ++ When a country is identified with a single or principal zone, ++ append 'T' to the country's ISO code, e.g. 'CVT' for ++ Cape Verde Time. For summer time append 'ST'; ++ for double summer time append 'DST'; etc. ++ Otherwise, take the first three letters of an English place ++ name identifying each zone and append 'T', 'ST', etc. ++ as before; e.g. 'VLAST' for VLAdivostok Summer Time. ++ ++ Use UT (with time zone abbreviation '-00') for locations while ++ uninhabited. The leading '-' is a flag that the time ++ zone is in some sense undefined; this notation is ++ derived from Internet RFC 3339. ++ ++Application writers should note that these abbreviations are ambiguous ++in practice: e.g. 'CST' has a different meaning in China than ++it does in the United States. In new applications, it's often better ++to use numeric UT offsets like '-0600' instead of time zone ++abbreviations like 'CST'; this avoids the ambiguity. ++ ++ ++----- Accuracy of the tz database ----- ++ ++The tz database is not authoritative, and it surely has errors. ++Corrections are welcome and encouraged; see the file CONTRIBUTING. ++Users requiring authoritative data should consult national standards ++bodies and the references cited in the database's comments. ++ ++Errors in the tz database arise from many sources: ++ ++ * The tz database predicts future time stamps, and current predictions ++ will be incorrect after future governments change the rules. ++ For example, if today someone schedules a meeting for 13:00 next ++ October 1, Casablanca time, and tomorrow Morocco changes its ++ daylight saving rules, software can mess up after the rule change ++ if it blithely relies on conversions made before the change. ++ ++ * The pre-1970 entries in this database cover only a tiny sliver of how ++ clocks actually behaved; the vast majority of the necessary ++ information was lost or never recorded. Thousands more zones would ++ be needed if the tz database's scope were extended to cover even ++ just the known or guessed history of standard time; for example, ++ the current single entry for France would need to split into dozens ++ of entries, perhaps hundreds. And in most of the world even this ++ approach would be misleading due to widespread disagreement or ++ indifference about what times should be observed. In her 2015 book ++ "The Global Transformation of Time, 1870-1950", Vanessa Ogle writes ++ "Outside of Europe and North America there was no system of time ++ zones at all, often not even a stable landscape of mean times, ++ prior to the middle decades of the twentieth century". See: ++ Timothy Shenk, Booked: A Global History of Time. Dissent 2015-12-17 ++ https://www.dissentmagazine.org/blog/booked-a-global-history-of-time-vanessa-ogle ++ ++ * Most of the pre-1970 data entries come from unreliable sources, often ++ astrology books that lack citations and whose compilers evidently ++ invented entries when the true facts were unknown, without ++ reporting which entries were known and which were invented. ++ These books often contradict each other or give implausible entries, ++ and on the rare occasions when they are checked they are ++ typically found to be incorrect. ++ ++ * For the UK the tz database relies on years of first-class work done by ++ Joseph Myers and others; see <http://www.polyomino.org.uk/british-time/>. ++ Other countries are not done nearly as well. ++ ++ * Sometimes, different people in the same city would maintain clocks ++ that differed significantly. Railway time was used by railroad ++ companies (which did not always agree with each other), ++ church-clock time was used for birth certificates, etc. ++ Often this was merely common practice, but sometimes it was set by law. ++ For example, from 1891 to 1911 the UT offset in France was legally ++ 0:09:21 outside train stations and 0:04:21 inside. ++ ++ * Although a named location in the tz database stands for the ++ containing region, its pre-1970 data entries are often accurate for ++ only a small subset of that region. For example, Europe/London ++ stands for the United Kingdom, but its pre-1847 times are valid ++ only for locations that have London's exact meridian, and its 1847 ++ transition to GMT is known to be valid only for the L&NW and the ++ Caledonian railways. ++ ++ * The tz database does not record the earliest time for which a zone's ++ data entries are thereafter valid for every location in the region. ++ For example, Europe/London is valid for all locations in its ++ region after GMT was made the standard time, but the date of ++ standardization (1880-08-02) is not in the tz database, other than ++ in commentary. For many zones the earliest time of validity is ++ unknown. ++ ++ * The tz database does not record a region's boundaries, and in many ++ cases the boundaries are not known. For example, the zone ++ America/Kentucky/Louisville represents a region around the city of ++ Louisville, the boundaries of which are unclear. ++ ++ * Changes that are modeled as instantaneous transitions in the tz ++ database were often spread out over hours, days, or even decades. ++ ++ * Even if the time is specified by law, locations sometimes ++ deliberately flout the law. ++ ++ * Early timekeeping practices, even assuming perfect clocks, were ++ often not specified to the accuracy that the tz database requires. ++ ++ * Sometimes historical timekeeping was specified more precisely ++ than what the tz database can handle. For example, from 1909 to ++ 1937 Netherlands clocks were legally UT +00:19:32.13, but the tz ++ database cannot represent the fractional second. ++ ++ * Even when all the timestamp transitions recorded by the tz database ++ are correct, the tz rules that generate them may not faithfully ++ reflect the historical rules. For example, from 1922 until World ++ War II the UK moved clocks forward the day following the third ++ Saturday in April unless that was Easter, in which case it moved ++ clocks forward the previous Sunday. Because the tz database has no ++ way to specify Easter, these exceptional years are entered as ++ separate tz Rule lines, even though the legal rules did not change. ++ ++ * The tz database models pre-standard time using the proleptic Gregorian ++ calendar and local mean time (LMT), but many people used other ++ calendars and other timescales. For example, the Roman Empire used ++ the Julian calendar, and had 12 varying-length daytime hours with a ++ non-hour-based system at night. ++ ++ * Early clocks were less reliable, and data entries do not represent ++ this unreliability. ++ ++ * As for leap seconds, civil time was not based on atomic time before ++ 1972, and we don't know the history of earth's rotation accurately ++ enough to map SI seconds to historical solar time to more than ++ about one-hour accuracy. See: Morrison LV, Stephenson FR. ++ Historical values of the Earth's clock error Delta T and the ++ calculation of eclipses. J Hist Astron. 2004;35:327-36 ++ <http://adsabs.harvard.edu/full/2004JHA....35..327M>; ++ Historical values of the Earth's clock error. J Hist Astron. 2005;36:339 ++ <http://adsabs.harvard.edu/full/2005JHA....36..339M>. ++ ++ * The relationship between POSIX time (that is, UTC but ignoring leap ++ seconds) and UTC is not agreed upon after 1972. Although the POSIX ++ clock officially stops during an inserted leap second, at least one ++ proposed standard has it jumping back a second instead; and in ++ practice POSIX clocks more typically either progress glacially during ++ a leap second, or are slightly slowed while near a leap second. ++ ++ * The tz database does not represent how uncertain its information is. ++ Ideally it would contain information about when data entries are ++ incomplete or dicey. Partial temporal knowledge is a field of ++ active research, though, and it's not clear how to apply it here. ++ ++In short, many, perhaps most, of the tz database's pre-1970 and future ++time stamps are either wrong or misleading. Any attempt to pass the ++tz database off as the definition of time should be unacceptable to ++anybody who cares about the facts. In particular, the tz database's ++LMT offsets should not be considered meaningful, and should not prompt ++creation of zones merely because two locations differ in LMT or ++transitioned to standard time at different dates. ++ ++ ++----- Time and date functions ----- ++ ++The tz code contains time and date functions that are upwards ++compatible with those of POSIX. ++ ++POSIX has the following properties and limitations. ++ ++* In POSIX, time display in a process is controlled by the ++ environment variable TZ. Unfortunately, the POSIX TZ string takes ++ a form that is hard to describe and is error-prone in practice. ++ Also, POSIX TZ strings can't deal with other (for example, Israeli) ++ daylight saving time rules, or situations where more than two ++ time zone abbreviations are used in an area. ++ ++ The POSIX TZ string takes the following form: ++ ++ stdoffset[dst[offset][,date[/time],date[/time]]] ++ ++ where: ++ ++ std and dst ++ are 3 or more characters specifying the standard ++ and daylight saving time (DST) zone names. ++ Starting with POSIX.1-2001, std and dst may also be ++ in a quoted form like "<UTC+10>"; this allows ++ "+" and "-" in the names. ++ offset ++ is of the form '[+-]hh:[mm[:ss]]' and specifies the ++ offset west of UT. 'hh' may be a single digit; 0<=hh<=24. ++ The default DST offset is one hour ahead of standard time. ++ date[/time],date[/time] ++ specifies the beginning and end of DST. If this is absent, ++ the system supplies its own rules for DST, and these can ++ differ from year to year; typically US DST rules are used. ++ time ++ takes the form 'hh:[mm[:ss]]' and defaults to 02:00. ++ This is the same format as the offset, except that a ++ leading '+' or '-' is not allowed. ++ date ++ takes one of the following forms: ++ Jn (1<=n<=365) ++ origin-1 day number not counting February 29 ++ n (0<=n<=365) ++ origin-0 day number counting February 29 if present ++ Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) ++ for the dth day of week n of month m of the year, ++ where week 1 is the first week in which day d appears, ++ and '5' stands for the last week in which day d appears ++ (which may be either the 4th or 5th week). ++ Typically, this is the only useful form; ++ the n and Jn forms are rarely used. ++ ++ Here is an example POSIX TZ string, for US Pacific time using rules ++ appropriate from 1987 through 2006: ++ ++ TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00' ++ ++ This POSIX TZ string is hard to remember, and mishandles time stamps ++ before 1987 and after 2006. With this package you can use this ++ instead: ++ ++ TZ='America/Los_Angeles' ++ ++* POSIX does not define the exact meaning of TZ values like "EST5EDT". ++ Typically the current US DST rules are used to interpret such values, ++ but this means that the US DST rules are compiled into each program ++ that does time conversion. This means that when US time conversion ++ rules change (as in the United States in 1987), all programs that ++ do time conversion must be recompiled to ensure proper results. ++ ++* The TZ environment variable is process-global, which makes it hard ++ to write efficient, thread-safe applications that need access ++ to multiple time zones. ++ ++* In POSIX, there's no tamper-proof way for a process to learn the ++ system's best idea of local wall clock. (This is important for ++ applications that an administrator wants used only at certain times - ++ without regard to whether the user has fiddled the "TZ" environment ++ variable. While an administrator can "do everything in UTC" to get ++ around the problem, doing so is inconvenient and precludes handling ++ daylight saving time shifts - as might be required to limit phone ++ calls to off-peak hours.) ++ ++* POSIX provides no convenient and efficient way to determine the UT ++ offset and time zone abbreviation of arbitrary time stamps, ++ particularly for time zone settings that do not fit into the ++ POSIX model. ++ ++* POSIX requires that systems ignore leap seconds. ++ ++* The tz code attempts to support all the time_t implementations ++ allowed by POSIX. The time_t type represents a nonnegative count of ++ seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds. ++ In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit ++ signed time_t values stop working after 2038-01-19 03:14:07 UTC, so ++ new implementations these days typically use a signed 64-bit integer. ++ Unsigned 32-bit integers are used on one or two platforms, ++ and 36-bit and 40-bit integers are also used occasionally. ++ Although earlier POSIX versions allowed time_t to be a ++ floating-point type, this was not supported by any practical ++ systems, and POSIX.1-2013 and the tz code both require time_t ++ to be an integer type. ++ ++These are the extensions that have been made to the POSIX functions: ++ ++* The "TZ" environment variable is used in generating the name of a file ++ from which time zone information is read (or is interpreted a la ++ POSIX); "TZ" is no longer constrained to be a three-letter time zone ++ name followed by a number of hours and an optional three-letter ++ daylight time zone name. The daylight saving time rules to be used ++ for a particular time zone are encoded in the time zone file; ++ the format of the file allows U.S., Australian, and other rules to be ++ encoded, and allows for situations where more than two time zone ++ abbreviations are used. ++ ++ It was recognized that allowing the "TZ" environment variable to ++ take on values such as "America/New_York" might cause "old" programs ++ (that expect "TZ" to have a certain form) to operate incorrectly; ++ consideration was given to using some other environment variable ++ (for example, "TIMEZONE") to hold the string used to generate the ++ time zone information file name. In the end, however, it was decided ++ to continue using "TZ": it is widely used for time zone purposes; ++ separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; ++ and systems where "new" forms of "TZ" might cause problems can simply ++ use TZ values such as "EST5EDT" which can be used both by ++ "new" programs (a la POSIX) and "old" programs (as zone names and ++ offsets). ++ ++* The code supports platforms with a UT offset member in struct tm, ++ e.g., tm_gmtoff. ++ ++* The code supports platforms with a time zone abbreviation member in ++ struct tm, e.g., tm_zone. ++ ++* Since the "TZ" environment variable can now be used to control time ++ conversion, the "daylight" and "timezone" variables are no longer ++ needed. (These variables are defined and set by "tzset"; however, their ++ values will not be used by "localtime.") ++ ++* Functions tzalloc, tzfree, localtime_rz, and mktime_z for ++ more-efficient thread-safe applications that need to use ++ multiple time zones. The tzalloc and tzfree functions ++ allocate and free objects of type timezone_t, and localtime_rz ++ and mktime_z are like localtime_r and mktime with an extra ++ timezone_t argument. The functions were inspired by NetBSD. ++ ++* A function "tzsetwall" has been added to arrange for the system's ++ best approximation to local wall clock time to be delivered by ++ subsequent calls to "localtime." Source code for portable ++ applications that "must" run on local wall clock time should call ++ "tzsetwall();" if such code is moved to "old" systems that don't ++ provide tzsetwall, you won't be able to generate an executable program. ++ (These time zone functions also arrange for local wall clock time to be ++ used if tzset is called - directly or indirectly - and there's no "TZ" ++ environment variable; portable applications should not, however, rely ++ on this behavior since it's not the way SVR2 systems behave.) ++ ++* Negative time_t values are supported, on systems where time_t is signed. ++ ++* These functions can account for leap seconds, thanks to Bradley White. ++ ++Points of interest to folks with other systems: ++ ++* Code compatible with this package is already part of many platforms, ++ including GNU/Linux, Android, the BSDs, Chromium OS, Cygwin, AIX, iOS, ++ BlackBery 10, macOS, Microsoft Windows, OpenVMS, and Solaris. ++ On such hosts, the primary use of this package ++ is to update obsolete time zone rule tables. ++ To do this, you may need to compile the time zone compiler ++ 'zic' supplied with this package instead of using the system 'zic', ++ since the format of zic's input is occasionally extended, ++ and a platform may still be shipping an older zic. ++ ++* The UNIX Version 7 "timezone" function is not present in this package; ++ it's impossible to reliably map timezone's arguments (a "minutes west ++ of GMT" value and a "daylight saving time in effect" flag) to a ++ time zone abbreviation, and we refuse to guess. ++ Programs that in the past used the timezone function may now examine ++ tzname[localtime(&clock)->tm_isdst] to learn the correct time ++ zone abbreviation to use. Alternatively, use ++ localtime(&clock)->tm_zone if this has been enabled. ++ ++* The 4.2BSD gettimeofday function is not used in this package. ++ This formerly let users obtain the current UTC offset and DST flag, ++ but this functionality was removed in later versions of BSD. ++ ++* In SVR2, time conversion fails for near-minimum or near-maximum ++ time_t values when doing conversions for places that don't use UT. ++ This package takes care to do these conversions correctly. ++ A comment in the source code tells how to get compatibly wrong ++ results. ++ ++The functions that are conditionally compiled if STD_INSPIRED is defined ++should, at this point, be looked on primarily as food for thought. They are ++not in any sense "standard compatible" - some are not, in fact, specified in ++*any* standard. They do, however, represent responses of various authors to ++standardization proposals. ++ ++Other time conversion proposals, in particular the one developed by folks at ++Hewlett Packard, offer a wider selection of functions that provide capabilities ++beyond those provided here. The absence of such functions from this package ++is not meant to discourage the development, standardization, or use of such ++functions. Rather, their absence reflects the decision to make this package ++contain valid extensions to POSIX, to ensure its broad acceptability. If ++more powerful time conversion functions can be standardized, so much the ++better. ++ ++ ++----- Interface stability ----- ++ ++The tz code and data supply the following interfaces: ++ ++ * A set of zone names as per "Names of time zone rules" above. ++ ++ * Library functions described in "Time and date functions" above. ++ ++ * The programs tzselect, zdump, and zic, documented in their man pages. ++ ++ * The format of zic input files, documented in the zic man page. ++ ++ * The format of zic output files, documented in the tzfile man page. ++ ++ * The format of zone table files, documented in zone1970.tab. ++ ++ * The format of the country code file, documented in iso3166.tab. ++ ++When these interfaces are changed, an effort is made to preserve ++backward compatibility. For example, tz data files typically do not ++rely on recently-added zic features, so that users can run older zic ++versions to process newer data files. ++ ++Interfaces not listed above are less stable. For example, users ++should not rely on particular UT offsets or abbreviations for time ++stamps, as data entries are often based on guesswork and these guesses ++may be corrected or improved. ++ ++ ++----- Calendrical issues ----- ++ ++Calendrical issues are a bit out of scope for a time zone database, ++but they indicate the sort of problems that we would run into if we ++extended the time zone database further into the past. An excellent ++resource in this area is Nachum Dershowitz and Edward M. Reingold, ++Calendrical Calculations: Third Edition, Cambridge University Press (2008) ++<http://emr.cs.iit.edu/home/reingold/calendar-book/third-edition/>. ++Other information and sources are given below. They sometimes disagree. ++ ++ ++France ++ ++Gregorian calendar adopted 1582-12-20. ++French Revolutionary calendar used 1793-11-24 through 1805-12-31, ++and (in Paris only) 1871-05-06 through 1871-05-23. ++ ++ ++Russia ++ ++From Chris Carrier (1996-12-02): ++On 1929-10-01 the Soviet Union instituted an "Eternal Calendar" ++with 30-day months plus 5 holidays, with a 5-day week. ++On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the ++Gregorian calendar while retaining the 6-day week; on 1940-06-27 it ++reverted to the 7-day week. With the 6-day week the usual days ++off were the 6th, 12th, 18th, 24th and 30th of the month. ++(Source: Evitiar Zerubavel, _The Seven Day Circle_) ++ ++ ++Mark Brader reported a similar story in "The Book of Calendars", edited ++by Frank Parise (1982, Facts on File, ISBN 0-8719-6467-8), page 377.

Grotefend, _Taschenbuch der Zeitrechnung des deutschen ++Mittelalters und der Neuzeit_, herausgegeben von Dr. O. Grotefend ++(Hannover: Hahnsche Buchhandlung, 1941), pp. 26-28. ++ ++ ++----- Time and time zones on Mars ----- ++ ++Some people's work schedules use Mars time. Jet Propulsion Laboratory ++(JPL) coordinators have kept Mars time on and off at least since 1997 ++for the Mars Pathfinder mission. Some of their family members have ++also adapted to Mars time. Dozens of special Mars watches were built ++for JPL workers who kept Mars time during the Mars Exploration ++Rovers mission (2004). These timepieces look like normal Seikos and ++Citizens but use Mars seconds rather than terrestrial seconds. ++ ++A Mars solar day is called a "sol" and has a mean period equal to ++about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is ++divided into a conventional 24-hour clock, so each Mars second equals ++about 1.02749125 terrestrial seconds. ++ ++The prime meridian of Mars goes through the center of the crater ++Airy-0, named in honor of the British astronomer who built the ++Greenwich telescope that defines Earth's prime meridian. Mean solar ++time on the Mars prime meridian is called Mars Coordinated Time (MTC). ++ ++Each landed mission on Mars has adopted a different reference for ++solar time keeping, so there is no real standard for Mars time zones. ++For example, the Mars Exploration Rover project (2004) defined two ++time zones "Local Solar Time A" and "Local Solar Time B" for its two ++missions, each zone designed so that its time equals local true solar ++time at approximately the middle of the nominal mission. Such a "time ++zone" is not particularly suited for any application other than the ++mission itself. ++ ++Many calendars have been proposed for Mars, but none have achieved ++wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a ++sequential count of Mars solar days elapsed since about 1873-12-29 ++12:00 GMT. ++ ++The tz database does not currently support Mars time, but it is ++documented here in the hopes that support will be added eventually. ++ ++Sources: ++ ++Michael Allison and Robert Schmunk, ++"Technical Notes on Mars Solar Time as Adopted by the Mars24 Sunclock" ++<http://www.giss.nasa.gov/tools/mars24/help/notes.html> (2012-08-08). ++ ++Jia-Rui Chong, "Workdays Fit for a Martian", Los Angeles Times ++<http://articles.latimes.com/2004/jan/14/science/sci-marstime14> ++(2004-01-14), pp A1, A20-A21. ++ ++Tom Chmielewski, "Jet Lag Is Worse on Mars", The Atlantic (2015-02-26) ++<http://www.theatlantic.com/technology/archive/2015/02/jet-lag-is-worse-on-mars/386033/> ++ ++----- ++ ++This file is in the public domain, so clarified as of 2009-05-17 by ++Arthur David Olson. ++ ++----- ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/africa.orig ++++ contrib/tzdata/africa +@@ -1,32 +1,32 @@ + # This file is in the public domain, so clarified as of + # 2009-05-17 by Arthur David Olson. + +-# This data is by no means authoritative; if you think you know better, ++# This file is by no means authoritative; if you think you know better, + # go ahead and edit the file (and please send any changes to +-# tz@iana.org for general use in the future). ++# tz@iana.org for general use in the future).

(Thanks to Alexander Belopolsky ++ for reporting the bug and suggesting a way forward.) ++ ++ If the installed localtime and/or posixrules files are symbolic ++ links, zic now keeps them symbolic links when updating them, for ++ compatibility with platforms like OpenSUSE where other programs ++ configure these files as symlinks. ++ ++ zic now avoids hard linking to symbolic links, avoids some ++ unnecessary mkdir and stat system calls, and uses shorter file ++ names internally. ++ ++ zdump has a new -i option to generate transitions in a ++ more-compact but still human-readable format. This option is ++ experimental, and the output format may change in future versions. ++ (Thanks to Jon Skeet for suggesting that an option was needed, ++ and thanks to Tim Parenti and Chris Rovick for further comments.) ++ ++ Changes to build procedure ++ ++ An experimental distribution format is available, in addition ++ to the traditional format which will continue to be distributed. ++ The new format is a tarball tzdb-VERSION.tar.lz with signature ++ file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory ++ tzdb-VERSION containing the code and data of the traditional ++ two-tarball format, along with extra data that may be useful. ++ (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others ++ for comments about the experimental format.) ++ ++ The release version number is now more accurate in the usual case ++ where releases are built from a Git repository. For example, if ++ 23 commits and some working-file changes have been made since ++ release 2016g, the version number is now something like ++ '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. ++ Official releases uses the same version number format as before, ++ e.g., '2016g'. To support the more-accurate version number, its ++ specification has moved from a line in the Makefile to a new ++ source file 'version'. ++ ++ The experimental distribution contains a file to2050.tzs that ++ contains what should be the output of 'zdump -i -c 2050' on ++ primary zones. If this file is available, 'make check' now checks ++ that zdump generates this output. ++ ++ 'make check_web' now works on Fedora-like distributions. ++ ++ Changes to documentation and commentary ++ ++ tzfile.5 now documents the new restriction on POSIX TZ-like ++ strings that is now implemented by zic. ++ ++ Comments now cite URLs for some 1917-1921 Russian DST decrees. ++ (Thanks to Alexander Belopolsky.) ++ ++ tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J ++ (thanks to Meno Hochschild) and ThreeTen-Extra, and its ++ description of Java 8 has been brought up to date (thanks to ++ Stephen Colebourne).

(Thanks to Christos Zoulas for reporting most of ++ these problems and for suggesting fixes.) ++ ++ If USG_COMPAT is defined and the requested time stamp is standard time, ++ the tz library's localtime and mktime functions now set the extern ++ variable timezone to a value appropriate for that time stamp; and ++ similarly for ALTZONE, daylight saving time, and the altzone variable. ++ This change is a companion to the tzname change in 2014h, and is ++ designed to make timezone and altzone more compatible with tzname. ++ ++ The tz library's functions now set errno to EOVERFLOW if they fail ++ because the result cannot be represented. ctime and ctime_r now ++ return NULL and set errno when a time stamp is out of range, rather ++ than having undefined behavior. ++ ++ Some bugs associated with the new 2014g functions have been fixed. ++ This includes a bug that largely incapacitated the new functions ++ time2posix_z and posix2time_z. (Thanks to Christos Zoulas.) ++ It also includes some uses of uninitialized variables after tzalloc. ++ The new code uses the standard type 'ssize_t', which the Makefile ++ now gives porting advice about. ++ ++ Changes affecting commentary ++ ++ Updated URLs for NRC Canada (thanks to Matt Johnson and Brian Inglis). ++ ++ ++Release 2014h - 2014-09-25 18:59:03 -0700 ++ ++ Changes affecting past time stamps ++ ++ America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28. ++ ++ Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01, ++ not 1920-01-06. The old entry was based on a misinterpretation of Shanks. ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Blantyre, Africa/Bujumbura, ++ Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi, ++ Africa/Lusaka, Africa/Maseru, and Africa/Mbabane. ++ ++ Changes affecting code ++ ++ zdump -V and -v now output gmtoff= values on all platforms, ++ not merely on platforms defining TM_GMTOFF. ++ ++ The tz library's localtime and mktime functions now set tzname to a value ++ appropriate for the requested time stamp, and zdump now uses this ++ on platforms not defining TM_ZONE, fixing a 2014g regression. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ The tz library no longer sets tzname if localtime or mktime fails. ++ ++ zdump -c no longer mishandles transitions near year boundaries. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ An access to uninitialized data has been fixed. ++ (Thanks to Jörg Richter for reporting the problem.) ++ ++ When THREAD_SAFE is defined, the code ports to the C11 memory model. ++ A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined ++ and two threads race to initialize data used by gmtime-like functions. ++ (Thanks to Andy Heninger for reporting the problems.) ++ ++ Changes affecting build procedure ++ ++ 'make check' now checks better for properly-sorted data. ++ ++ Changes affecting documentation and commentary ++ ++ zdump's gmtoff=N output is now documented, and its isdst=D output ++ is now documented to possibly output D values other than 0 or 1. ++ ++ zdump -c's treatment of years is now documented to use the ++ Gregorian calendar and Universal Time without leap seconds, ++ and its behavior at cutoff boundaries is now documented better. ++ (Thanks to Arthur David Olson and Tim Parenti for reporting the problems.) ++ ++ Programs are now documented to use the proleptic Gregorian calendar. ++ (Thanks to Alan Barrett for the suggestion.) ++ ++ Fractional-second GMT offsets have been documented for civil time ++ in 19th-century Chennai, Jakarta, and New York. ++ ++ ++Release 2014g - 2014-08-28 12:31:23 -0700 ++ ++ Changes affecting future time stamps ++ ++ Turks & Caicos is switching from US eastern time to UT -04 ++ year-round, modeled as a switch on 2014-11-02 at 02:00. ++ [As noted in 2014j, this switch was later delayed.] ++ ++ Changes affecting past time stamps ++ ++ Time in Russia or the USSR before 1926 or so has been corrected by ++ a few seconds in the following zones: Asia/Irkutsk, ++ Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi, ++ Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For ++ Asia/Yekaterinburg the correction is a few minutes. (Thanks to ++ Vladimir Karpinsky.) ++ ++ The Portuguese decree of 1911-05-26 took effect on 1912-01-01. ++ This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, ++ Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912 ++ GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. ++ (Thanks to Stephen Colebourne for pointing to the decree.) ++ ++ Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59. ++ ++ A new file 'backzone' contains data which may appeal to ++ connoisseurs of old time stamps, although it is out of scope for ++ the tz database, is often poorly sourced, and contains some data ++ that is known to be incorrect. The new file is not recommended ++ for ordinary use and its entries are not installed by default. ++ (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and ++ Isle of Man entries.) ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Bangui, Africa/Brazzaville, ++ Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, ++ Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. ++ ++ Changes affecting code ++ ++ Unless NETBSD_INSPIRED is defined to 0, the tz library now ++ supplies functions for creating and using objects that represent ++ time zones. The new functions are tzalloc, tzfree, localtime_rz, ++ mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and ++ time2posix_z. They are intended for performance: for example, ++ localtime_rz (unlike localtime_r) is trivially thread-safe without ++ locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired ++ functions, and to Alan Barrett and Jonathan Lennox for helping to ++ debug the change.) ++ ++ zdump now builds with the tz library unless USE_LTZ is defined to 0, ++ This lets zdump use tz features even if the system library lacks them. ++ To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 ++ TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. ++ ++ zdump now uses localtime_rz if available, as it's significantly faster, ++ and it can help zdump better diagnose invalid time zone names. ++ Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ ++ defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is ++ not available, zdump now uses localtime_r and tzset if available, ++ as this is a bit cleaner and faster than plain localtime. Compile ++ with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system ++ lacks these two functions. ++ ++ If THREAD_SAFE is defined to 1, the tz library is now thread-safe. ++ Although not needed for tz's own applications, which are single-threaded, ++ this supports POSIX better if the tz library is used in multithreaded apps. ++ ++ Some crashes have been fixed when zdump or the tz library is given ++ invalid or outlandish input. ++ ++ The tz library no longer mishandles leap seconds on platforms with ++ unsigned time_t in time zones that lack ordinary transitions after 1970. ++ ++ The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not ++ already defined, to make it easier to configure on common platforms. ++ Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. ++ ++ Unless the new macro UNINIT_TRAP is defined to 1, the tz code now ++ assumes that reading uninitialized memory yields garbage values ++ but does not cause other problems such as traps. ++ ++ If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now ++ more likely to guess right for ambiguous time stamps near ++ transitions where tm_isdst does not change. ++ ++ If HAVE_STRFTIME_L is defined to 1, the tz library now defines ++ strftime_l for compatibility with recent versions of POSIX. ++ Only the C locale is supported, though. HAVE_STRFTIME_L defaults ++ to 1 on recent POSIX versions, and to 0 otherwise. ++ ++ tzselect -c now uses a hybrid distance measure that works better ++ in Africa. (Thanks to Alan Barrett for noting the problem.) ++ ++ The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, ++ or when time_tz is defined. ++ ++ When HAVE_UTMPX_H is set the 'date' command now builds on systems ++ whose <utmpx.h> file does not define WTMPX_FILE, and when setting ++ the date it updates the wtmpx file if _PATH_WTMPX is defined. ++ This affects GNU/Linux and similar systems. ++ ++ For easier maintenance later, some C code has been simplified, ++ some lint has been removed, and the code has been tweaked so that ++ plain 'make' is more likely to work. ++ ++ The C type 'bool' is now used for boolean values, instead of 'int'. ++ ++ The long-obsolete LOCALE_HOME code has been removed. ++ ++ The long-obsolete 'gtime' function has been removed. ++ ++ Changes affecting build procedure ++ ++ 'zdump' no longer links in ialloc.o, as it's not needed. ++ ++ 'make check_time_t_alternatives' no longer assumes GNU diff. ++ ++ Changes affecting distribution tarballs ++ ++ The files checktab.awk and zoneinfo2tdf.pl are now distributed in ++ the tzdata tarball instead of the tzcode tarball, since they help ++ maintain the data. The NEWS and Theory files are now also ++ distributed in the tzdata tarball, as they're relevant for data. ++ (Thanks to Alan Barrett for pointing this out.) Also, the ++ leapseconds.awk file is no longer distributed in the tzcode ++ tarball, since it belongs in the tzdata tarball (where 2014f ++ inadvertently also distributed it). ++ ++ Changes affecting documentation and commentary ++ ++ A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for ++ suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms ++ for debugging it.) ++ ++ The man pages have been updated to use function prototypes, ++ to document thread-safe variants like localtime_r, and to document ++ the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and ++ mktime_z. ++ ++ The fields in Link lines have been renamed to be more descriptive ++ and more like the parameters of 'ln'. LINK-FROM has become TARGET, ++ and LINK-TO has become LINK-NAME. ++ ++ tz-link.htm mentions the IETF's tzdist working group; Windows ++ Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. ++ ++ Some broken URLs have been fixed in the commentary. (Thanks to ++ Lester Caine.) ++ ++ Commentary about Philippines DST has been updated, and commentary ++ on pre-1970 time in India has been added. ++ ++ ++Release 2014f - 2014-08-05 17:42:36 -0700 ++ ++ Changes affecting future time stamps ++ ++ Russia will subtract an hour from most of its time zones on 2014-10-26 ++ at 02:00 local time. (Thanks to Alexander Krivenyshev.) ++ There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky ++ Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug ++ (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast ++ (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic ++ (Europe/Samara) are not changing their clocks. The changed zones are ++ Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, ++ Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, ++ Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, ++ Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours ++ subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, ++ but not its UTC offset. Two zones are added: Asia/Chita (split ++ from Asia/Yakutsk, and also with two hours subtracted) and ++ Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour ++ subtracted). (Thanks to Tim Parenti for much of the above.) ++ ++ Changes affecting time zone abbreviations ++ ++ Australian eastern time zone abbreviations are now AEST/AEDT not EST, ++ and similarly for the other Australian zones. That is, for eastern ++ standard and daylight saving time the abbreviations are AEST and AEDT ++ instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT, ++ and AWST/AWDT are now used instead of the former CST, CWST, and WST. ++ This change does not affect UTC offsets, only time zone abbreviations. ++ (Thanks to Rich Tibbett and many others.) ++ ++ Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UT +07) ++ effective 2014-10-26 at 02:00 local time. ++ ++ The time zone abbreviation for Xinjiang Time (observed in Ürümqi) ++ has been changed from URUT to XJT. (Thanks to Luther Ma.) ++ ++ Prefer MSK/MSD for Moscow time in Russia, even in other cities. ++ Similarly, prefer EET/EEST for eastern European time in Russia. ++ ++ Change time zone abbreviations in (western) Samoa to use "ST" and ++ "DT" suffixes, as this is more likely to match common practice. ++ Prefix "W" to (western) Samoa time when its standard-time offset ++ disagrees with that of American Samoa. ++ ++ America/Metlakatla now uses PST, not MeST, to abbreviate its time zone. ++ ++ Time zone abbreviations have been updated for Japan's two time ++ zones used 1896-1937. JWST now stands for Western Standard ++ Time, and JCST for Central Standard Time (formerly this was CJT). ++ These abbreviations are now used for time in Korea, Taiwan, ++ and Sakhalin while controlled by Japan. ++ ++ Changes affecting past time stamps ++ ++ China's five zones have been simplified to two, since the post-1970 ++ differences in the other three seem to have been imaginary. The ++ zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been ++ removed; backwards-compatibility links still work, albeit with ++ different behaviors for time stamps before May 1980. Asia/Urumqi's ++ 1980 transition to UT +08 has been removed, so that it is now at ++ +06 and not +08. (Thanks to Luther Ma and to Alois Treindl; ++ Treindl sent helpful translations of two papers by Guo Qingsheng.) ++ ++ Some zones have been turned into links, when they differed from existing ++ zones only for older UTC offsets where data entries were likely invented. ++ These changes affect UTC offsets in pre-1970 time stamps only. This is ++ similar to the change in release 2013e, except this time for western ++ Africa. The affected zones are: Africa/Bamako, Africa/Banjul, ++ Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, ++ Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and ++ Atlantic/St_Helena. This also affects the backwards-compatibility ++ link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, ++ Tim Parenti, and David Patte for reporting problems in earlier ++ versions of this change.) ++ ++ Asia/Shanghai's pre-standard-time UT offset has been changed from ++ 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its ++ transition to standard time has been changed from 1928 to 1901. ++ ++ Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, ++ then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. ++ In 1946 it observed DST from 05-15 through 09-30; in 1947 ++ from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. ++ (Thanks to Yu-Cheng Chuang.) ++ ++ Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. ++ ++ Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not ++ 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) ++ ++ Pacific/Pago_Pago has been changed from UT -11:30 to -11 for the ++ period from 1911 to 1950. ++ ++ Pacific/Chatham has been changed to New Zealand standard time plus ++ 45 minutes for the period before 1957, reflecting a 1956 remark in ++ the New Zealand parliament. ++ ++ Europe/Budapest has several pre-1946 corrections: in 1918 the transition ++ out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in ++ 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 ++ not 04-06 at 02:00; and there was no DST in 1920. ++ ++ Africa/Accra is now assumed to have observed DST from 1920 through 1935. ++ ++ Time in Russia before 1927 or so has been corrected by a few seconds in ++ the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, ++ Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and ++ Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 ++ point. (Thanks to Vladimir Karpinsky for the Moscow changes.) ++ ++ Changes affecting data format ++ ++ A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. ++ The new file's extended format allows multiple country codes per zone. ++ The older file is still installed but is deprecated; its format is ++ not changing and it will still be distributed for a while, but new ++ applications should use the new file. ++ ++ The new file format simplifies maintenance of obscure locations. ++ To test this, it adds coverage for the Crozet Islands and the ++ Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) ++ ++ The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. ++ It is still ASCII now, but commentary about the switch has been added. ++ The new file 'zone1970.tab' already uses UTF-8. ++ ++ Changes affecting code ++ ++ 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE ++ is defined. (Thanks to Elliott Hughes for reporting the problem.) ++ ++ 'zic' no longer mishandles input when ignoring case in locales that ++ are not compatible with English, e.g., unibyte Turkish locales when ++ compiled with HAVE_GETTEXT. ++ ++ Error diagnostics of 'zic' and 'yearistype' have been reworded so that ++ they no longer use ASCII '-' as if it were a dash. ++ ++ 'zic' now rejects output file names that contain '.' or '..' components. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ 'zic -v' now warns about output file names that do not follow ++ POSIX rules, or that contain a digit or '.'. (Thanks to Arthur ++ David Olson for starting the ball rolling on this.) ++ ++ Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. ++ ++ Changes affecting build procedure ++ ++ 'zic' no longer links in localtime.o and asctime.o, as they're not needed. ++ (Thanks to John Cochran.) ++ ++ Changes affecting documentation and commentary ++ ++ The 'Theory' file documents legacy names, the longstanding ++ exceptions to the POSIX-inspired file name rules. ++ ++ The 'zic' documentation clarifies the role of time types when ++ interpreting dates. (Thanks to Arthur David Olson.) ++ ++ Documentation and commentary now prefer UTF-8 to US-ASCII, ++ allowing the use of proper accents in foreign words and names. ++ Code and data have not changed because of this. (Thanks to ++ Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug ++ this.) ++ ++ Non-HTML documentation and commentary now use plain-text URLs instead of ++ HTML insertions, and are more consistent about bracketing URLs when they ++ are not already surrounded by white space. (Thanks to suggestions by ++ Steffen Nurpmeso.) ++ ++ There is new commentary about Xujiahui Observatory, the five time-zone ++ project in China from 1918 to 1949, timekeeping in Japanese-occupied ++ Shanghai, and Tibet Time in the 1950s. The sharp-eyed can spot the ++ warlord Jin Shuren in the data. ++ ++ Commentary about the coverage of each Russian zone has been standardized. ++ (Thanks to Tim Parenti). ++ ++ There is new commentary about contemporary timekeeping in Ethiopia. ++ ++ Obsolete comments about a 2007 proposal for DST in Kuwait has been removed. ++ ++ There is new commentary about time in Poland in 1919. ++ ++ Proper credit has been given to DST inventor George Vernon Hudson. ++ ++ Commentary about time in Metlakatla, AK and Resolute, NU has been ++ improved, with a new source for the former. ++ ++ In zone.tab, Pacific/Easter no longer mentions Salas y Gómez, as it ++ is uninhabited. ++ ++ Commentary about permanent Antarctic bases has been updated. ++ ++ Several typos have been corrected. (Thanks to Tim Parenti for ++ contributing some of these fixes.) ++ ++ tz-link.htm now mentions the JavaScript libraries Moment Timezone, ++ TimezoneJS.Date, Walltime-js, and Timezone. (Thanks to a heads-up ++ from Matt Johnson.) Also, it mentions the Go 'latlong' package. ++ (Thanks to a heads-up from Dirkjan Ochtman.) ++ ++ The files usno1988, usno1989, usno1989a, usno1995, usno1997, and usno1998 ++ have been removed. These obsolescent US Naval Observatory entries were no ++ longer helpful for maintenance. (Thanks to Tim Parenti for the suggestion.) ++ ++ ++Release 2014e - 2014-06-12 21:53:52 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00. ++ (Thanks to Imed Chihi.)

Guess that from 2015 on Morocco will ++ temporarily switch to standard time at 03:00 the last Saturday before ++ Ramadan, and back to DST at 02:00 the first Saturday after Ramadan. ++ ++ Changes affecting past time stamps ++ ++ The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of ++ "MSD" for Moscow's double daylight time in summer 1921. Also, a typo ++ "VLASST" has been repaired to be "VLAST" for Vladivostok summer time ++ in 1991. (Thanks to Hank W. for reporting the problems.) ++ ++ Changes affecting commentary ++ ++ tz-link.htm now cites RFC 7265 for jCal, mentions PTP and the ++ draft CalDAV extension, updates URLs for TSP, TZInfo, IATA, and ++ removes stale pointers to World Time Explorer and WORLDTIME. ++ ++ ++Release 2014d - 2014-05-27 21:34:40 -0700 ++ ++ Changes affecting code ++ ++ zic no longer generates files containing time stamps before the Big Bang. ++ This works around GNOME bug 730332 ++ <https://bugzilla.gnome.org/show_bug.cgi?id=730332>. ++ (Thanks to Leonardo Chiquitto for reporting the bug, and to ++ Arthur David Olson and James Cloos for suggesting improvements to the fix.) ++ ++ Changes affecting documentation ++ ++ tz-link.htm now mentions GNOME. ++ ++ ++Release 2014c - 2014-05-13 07:44:13 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Egypt observes DST starting 2014-05-15 at 24:00. ++ (Thanks to Ahmad El-Dardiry and Gunther Vermier.) ++ Details have not been announced, except that DST will not be observed ++ during Ramadan.

(Thanks to Michael Forney.) ++ ++ A dependency typo in the 'zdump' rule has been fixed. ++ (Thanks to Andrew Paprocki.) ++ ++ The Makefile has been simplified by assuming that 'mkdir -p' and 'cp -f' ++ work as specified by POSIX.2-1992 or later; this is portable nowadays. ++ ++ 'make clean' no longer removes 'leapseconds', since it's ++ host-independent and is part of the distribution. ++ ++ The unused makefile macros TZCSRCS, TZDSRCS, DATESRCS have been removed. ++ ++ Changes affecting documentation and commentary ++ ++ tz-link.htm now mentions TC TIMEZONE's draft time zone service protocol ++ (thanks to Mike Douglass) and TimezoneJS.Date (thanks to Jim Fehrle). ++ ++ Update URLs in tz-link page. Add URLs for Microsoft Windows, since ++ 8.1 introduces tz support. Remove URLs for Tru64 and UnixWare (no ++ longer maintained) and for old advisories. SOFA now does C. ++ ++Release 2013g - 2013-09-30 21:08:26 -0700 ++ ++ Changes affecting current and near-future time stamps ++ ++ Morocco now observes DST from the last Sunday in March to the last ++ Sunday in October, not April to September respectively. (Thanks ++ to Steffen Thorsen.) ++ ++ Changes affecting 'zic' ++ ++ 'zic' now runs on platforms that lack both hard links and symlinks. ++ (Thanks to Theo Veenker for reporting the problem, for MinGW.) ++ Also, fix some bugs on platforms that lack hard links but have symlinks. ++ ++ 'zic -v' again warns that Asia/Tehran has no POSIX environment variable ++ to predict the far future, fixing a bug introduced in 2013e. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is again put into the tzdata tarball. ++ Also, 'leapseconds.awk', so tzdata is self-contained. (Thanks to ++ Matt Burgess and Ian Abbott.) The timestamps of these and other ++ dependent files in tarballs are adjusted more consistently. ++ ++ Changes affecting documentation and commentary ++ ++ The README file is now part of the data tarball as well as the code. ++ It now states that files are public domain unless otherwise specified. ++ (Thanks to Andrew Main (Zefram) for asking for clarifications.) ++ Its details about the 1989 release moved to a place of honor near ++ the end of NEWS. ++ ++ ++Release 2013f - 2013-09-24 23:37:36 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Tocantins will very likely not observe DST starting this spring. ++ (Thanks to Steffen Thorsen.) ++ ++ Jordan will likely stay at UT +03 indefinitely, and will not fall ++ back this fall. ++ ++ Palestine will fall back at 00:00, not 01:00. (Thanks to Steffen Thorsen.) ++ ++ Changes affecting API ++ ++ The types of the global variables 'timezone' and 'altzone' (if present) ++ have been changed back to 'long'. This is required for 'timezone' ++ by POSIX, and for 'altzone' by common practice, e.g., Solaris 11. ++ These variables were originally 'long' in the tz code, but were ++ mistakenly changed to 'time_t' in 1987; nobody reported the ++ incompatibility until now. The difference matters on x32, where ++ 'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.) ++ ++ Changes affecting the build procedure ++ ++ Avoid long strings in leapseconds.awk to work around a mawk bug. ++ (Thanks to Cyril Baurand.) ++ ++ Changes affecting documentation and commentary ++ ++ New file 'NEWS' that contains release notes like this one. ++ ++ Paraguay's law does not specify DST transition time; 00:00 is customary. ++ (Thanks to Waldemar Villamayor-Venialbo.) ++ ++ Minor capitalization fixes. ++ ++ Changes affecting version-control only ++ ++ The experimental GitHub repository now contains annotated and ++ signed tags for recent releases, e.g., '2013e' for Release 2013e. ++ Releases are tagged starting with 2012e; earlier releases were ++ done differently, and tags would either not have a simple name or ++ not exactly match what was released. ++ ++ 'make set-timestamps' is now simpler and a bit more portable. ++ ++ ++Release 2013e - 2013-09-19 23:50:04 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ This year Fiji will start DST on October 27, not October 20. ++ (Thanks to David Wheeler for the heads-up.) For now, guess that ++ Fiji will continue to spring forward the Sunday before the fourth ++ Monday in October. ++ ++ Changes affecting current and future time zone abbreviations ++ ++ Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian ++ time zone abbreviations since 1932. (Thanks to George Ziegler, ++ Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and ++ Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, ++ Asia/Makassar, and Asia/Pontianak. ++ ++ Use ART (UT -03, standard time), rather than WARST (also -03, but ++ daylight saving time) for San Luis, Argentina since 2009. ++ ++ Changes affecting Godthåb time stamps after 2037 if version mismatch ++ ++ Allow POSIX-like TZ strings where the transition time's hour can ++ range from -167 through 167, instead of the POSIX-required 0 ++ through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the ++ new Fiji rules. This is a more-compact way to represent ++ far-future time stamps for America/Godthab, America/Santiago, ++ Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, ++ Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by ++ this change. (Derived from a suggestion by Arthur David Olson.) ++ ++ Allow POSIX-like TZ strings where daylight saving time is in ++ effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western ++ Argentina Summer Time all year. This supports a more-compact way ++ to represent the 2013d data for America/Argentina/San_Luis. ++ Because of the change for San Luis noted above this change does not ++ affect the current data. (Thanks to Andrew Main (Zefram) for ++ suggestions that improved this change.) ++ ++ Where these two TZ changes take effect, there is a minor extension ++ to the tz file format in that it allows new values for the ++ embedded TZ-format string, and the tz file format version number ++ has therefore been increased from 2 to 3 as a precaution. ++ Version-2-based client code should continue to work as before for ++ all time stamps before 2038. Existing version-2-based client code ++ (tzcode, GNU/Linux, Solaris) has been tested on version-3-format ++ files, and typically works in practice even for time stamps after ++ 2037; the only known exception is America/Godthab. ++ ++ Changes affecting time stamps before 1970 ++ ++ Pacific/Johnston is now a link to Pacific/Honolulu. This corrects ++ some errors before 1947. ++ ++ Some zones have been turned into links, when they differ from existing ++ zones only in older data entries that were likely invented or that ++ differ only in LMT or transitions from LMT. These changes affect ++ only time stamps before 1943. The affected zones are: ++ Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, ++ America/Grenada, America/Guadeloupe, America/Marigot, ++ America/Montserrat, America/St_Barthelemy, America/St_Kitts, ++ America/St_Lucia, America/St_Thomas, America/St_Vincent, ++ America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for ++ confirming that the old Europe/Vaduz zone was wrong and the new ++ link is better for WWII-era times.) ++ ++ Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects ++ America/Cayman, America/Jamaica and America/Grand_Turk time stamps ++ from 1890 to 1912. ++ ++ Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. ++ This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks ++ to Alois Treindl). ++ ++ Change the date of the circa-1850 Zurich transition from 1849-09-12 ++ to 1853-07-16, overriding Shanks with data from Messerli about ++ postal and telegraph time in Switzerland. ++ ++ Changes affecting time zone abbreviations before 1970 ++ ++ For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, ++ as Jakarta was called Batavia back then. ++ ++ Changes affecting API ++ ++ The 'zic' command now outputs a dummy transition when far-future ++ data can't be summarized using a TZ string, and uses a 402-year ++ window rather than a 400-year window. For the current data, this ++ affects only the Asia/Tehran file. It does not affect any of the ++ time stamps that this file represents, so zdump outputs the same ++ information as before. (Thanks to Andrew Main (Zefram).) ++ ++ The 'date' command has a new '-r' option, which lets you specify ++ the integer time to display, a la FreeBSD. ++ ++ The 'tzselect' command has two new options '-c' and '-n', which lets you ++ select a zone based on latitude and longitude. ++ ++ The 'zic' command's '-v' option now warns about constructs that ++ require the new version-3 binary file format. (Thanks to Arthur ++ David Olson for the suggestion.) ++ ++ Support for floating-point time_t has been removed. ++ It was always dicey, and POSIX no longer requires it. ++ (Thanks to Eric Blake for suggesting to the POSIX committee to ++ remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy ++ Heninger, Arthur David Olson, and Alois Treindl, for reporting ++ bugs and elucidating some of the corners of the old floating-point ++ implementation.) ++ ++ The signatures of 'offtime', 'timeoff', and 'gtime' have been ++ changed back to the old practice of using 'long' to represent UT ++ offsets. This had been inadvertently and mistakenly changed to ++ 'int_fast32_t'. (Thanks to Christos Zoulas.) ++ ++ The code avoids undefined behavior on integer overflow in some ++ more places, including gmtime, localtime, mktime and zdump. ++ ++ Changes affecting the zdump utility ++ ++ zdump now outputs "UT" when referring to Universal Time, not "UTC". ++ "UTC" does not make sense for time stamps that predate the introduction ++ of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen ++ for clarifying UT vs UTC.) ++ ++ Data changes affecting behavior of tzselect and similar programs ++ ++ Country code BQ is now called the more-common name "Caribbean Netherlands" ++ rather than the more-official "Bonaire, St Eustatius & Saba". ++ ++ Remove from zone.tab the names America/Montreal, America/Shiprock, ++ and Antarctica/South_Pole, as they are equivalent to existing ++ same-country-code zones for post-1970 time stamps. The data entries for ++ these names are unchanged, so the names continue to work as before. ++ ++ Changes affecting code internals ++ ++ zic -c now runs way faster on 64-bit hosts when given large numbers. ++ ++ zic now uses vfprintf to avoid allocating and freeing some memory. ++ ++ tzselect now computes the list of continents from the data, ++ rather than have it hard-coded. ++ ++ Minor changes pacify GCC 4.7.3 and GCC 4.8.1. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is now generated automatically from a ++ new file 'leap-seconds.list', which is a copy of ++ <ftp://time.nist.gov/pub/leap-seconds.list>. ++ A new source file 'leapseconds.awk' implements this. ++ The goal is simplification of the future maintenance of 'leapseconds'. ++ ++ When building the 'posix' or 'right' subdirectories, if the ++ subdirectory would be a copy of the default subdirectory, it is ++ now made a symbolic link if that is supported. This saves about ++ 2 MB of file system space. ++ ++ The links America/Shiprock and Antarctica/South_Pole have been ++ moved to the 'backward' file. This affects only nondefault builds ++ that omit 'backward'. ++ ++ Changes affecting version-control only ++ ++ .gitignore now ignores 'date'. ++ ++ Changes affecting documentation and commentary ++ ++ Changes to the 'tzfile' man page ++ ++ It now mentions that the binary file format may be extended in ++ future versions by appending data. ++ ++ It now refers to the 'zdump' and 'zic' man pages. ++ ++ Changes to the 'zic' man page ++ ++ It lists conditions that elicit a warning with '-v'. ++ ++ It says that the behavior is unspecified when duplicate names ++ are given, or if the source of one link is the target of another. ++ ++ Its examples are updated to match the latest data. ++ ++ The definition of white space has been clarified slightly. ++ (Thanks to Michael Deckers.) ++ ++ Changes to the 'Theory' file ++ ++ There is a new section about the accuracy of the tz database, ++ describing the many ways that errors can creep in, and ++ explaining why so many of the pre-1970 time stamps are wrong or ++ misleading (thanks to Steve Allen, Lester Caine, and Garrett ++ Wollman for discussions that contributed to this). ++ ++ The 'Theory' file describes LMT better (this follows a ++ suggestion by Guy Harris). ++ ++ It refers to the 2013 edition of POSIX rather than the 2004 edition. ++ ++ It's mentioned that excluding 'backward' should not affect the ++ other data, and it suggests at least one zone.tab name per ++ inhabited country (thanks to Stephen Colebourne). ++ ++ Some longstanding restrictions on names are documented, e.g., ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ ++ It gives more reasons for the 1970 cutoff. ++ ++ It now mentions which time_t variants are supported, such as ++ signed integer time_t. (Thanks to Paul Goyette for reporting ++ typos in an experimental version of this change.) ++ ++ (Thanks to Philip Newton for correcting typos in these changes.) ++ ++ Documentation and commentary is more careful to distinguish UT in ++ general from UTC in particular. (Thanks to Steve Allen.) ++ ++ Add a better source for the Zurich 1894 transition. ++ (Thanks to Pierre-Yves Berger.) ++ ++ Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.) ++ ++ ++Release 2013d - 2013-07-05 07:38:01 -0700 ++ ++ Changes affecting future time stamps: ++ ++ Morocco's midsummer transitions this year are July 7 and August 10, ++ not July 9 and August 8. (Thanks to Andrew Paprocki.) ++ ++ Israel now falls back on the last Sunday of October. ++ (Thanks to Ephraim Silverberg.) ++ ++ Changes affecting past time stamps: ++ ++ Specify Jerusalem's location more precisely; this changes the pre-1880 ++ times by 2 s. ++ ++ Changing affecting metadata only: ++ ++ Fix typos in the entries for country codes BQ and SX. ++ ++ Changes affecting code: ++ ++ Rework the code to fix a bug with handling Australia/Macquarie on ++ 32-bit hosts (thanks to Arthur David Olson). ++ ++ Port to platforms like NetBSD, where time_t can be wider than long. ++ ++ Add support for testing time_t types other than the system's. ++ Run 'make check_time_t_alternatives' to try this out. ++ Currently, the tests fail for unsigned time_t; ++ this should get fixed at some point. ++ ++ Changes affecting documentation and commentary: ++ ++ Deemphasize the significance of national borders. ++ ++ Update the zdump man page. ++ ++ Remove obsolete NOID comment (thanks to Denis Excoffier). ++ ++ Update several URLs and comments in the web pages. ++ ++ Spelling fixes (thanks to Kevin Lyda and Jonathan Leffler). ++ ++ Update URL for CLDR Zone->Tzid table (thanks to Yoshito Umaoka). ++ ++ ++Release 2013c - 2013-04-19 16:17:40 -0700 ++ ++ Changes affecting current and future time stamps: ++ ++ Palestine observed DST starting March 29, 2013.

Second, the Pridnestrovian Moldavian Republic ++ (Europe/Tiraspol) decided not to split from the rest of Moldova after ++ all, and consequently that zone has been removed (again) and reinstated ++ in the "backward" file as a link to Europe/Chisinau. And third, the ++ end date for Fiji's summer time this summer was moved forward from the ++ earlier planned Feb 26, to Jan 22. ++ ++ Apart from that, Moldova (MD) returns to a single entry in zone.tab ++ (and the incorrect syntax that was in the 2011m version of that file ++ is so fixed - it would have been fixed in a different way had this ++ change not happened - that's the "missing" sccs version id). ++ ++ ++Release data2011m - 2011-10-24 21:42:16 +0700 ++ ++ In particular, the typos in comments in the data (2011-11-17 should have ++ been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that ++ Tim Parenti noted) have been fixed, and the change for Ukraine has been ++ made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to ++ Tim Parenti, and also Denys Gavrysh) ++ ++ In addition, I added Europe/Tiraspol to zone.tab. ++ ++ This time, all the files have new version numbers...

The text has been ++adapted and reformatted for the purposes of this file. ++ ++Traditionally a release R consists of a pair of tarball files, ++tzcodeR.tar.gz and tzdataR.tar.gz. However, some releases (e.g., ++code2010a, data2012c) consist of just one or the other tarball, and a ++few (e.g., code2012c-data2012d) have tarballs with mixed version ++numbers. Recent releases also come in an experimental format ++consisting of a single tarball tzdb-R.tar.lz with extra data. ++ ++Release time stamps are taken from the release's commit (for newer, ++Git-based releases), from the newest file in the tarball (for older ++releases, where this info is available) or from the email announcing ++the release (if all else fails; these are marked with a time zone of ++-0000 and an "is missing!" comment). ++ ++Earlier versions of the code and data were not announced on the tz ++list and are not summarized here. ++ ++This file is in the public domain. ++ ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/README.orig ++++ contrib/tzdata/README +@@ -0,0 +1,71 @@ ++README for the tz distribution ++ ++"What time is it?" -- Richard Deacon as The King ++"Any time you want it to be." -- Frank Baxter as The Scientist ++ (from the Bell System film "About Time") ++ ++The Time Zone Database (often called tz or zoneinfo) contains code and ++data that represent the history of local time for many representative ++locations around the globe.

To represent this ++data, the world is partitioned into regions whose clocks all agree ++about time stamps that occur after the somewhat-arbitrary cutoff point ++of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region, ++the database records all known clock transitions, and labels the region ++with a notable location. Although 1970 is a somewhat-arbitrary ++cutoff, there are significant challenges to moving the cutoff earlier ++even by a decade or two, due to the wide variety of local practices ++before computer timekeeping became prevalent. ++ ++Clock transitions before 1970 are recorded for each such location, ++because most systems support time stamps before 1970 and could ++misbehave if data entries were omitted for pre-1970 transitions. ++However, the database is not designed for and does not suffice for ++applications requiring accurate handling of all past times everywhere, ++as it would take far too much effort and guesswork to record all ++details of pre-1970 civil timekeeping. ++ ++As described below, reference source code for using the tz database is ++also available. The tz code is upwards compatible with POSIX, an ++international standard for UNIX-like systems. As of this writing, the ++current edition of POSIX is: ++ ++ The Open Group Base Specifications Issue 7 ++ IEEE Std 1003.1, 2013 Edition ++ <http://pubs.opengroup.org/onlinepubs/9699919799/> ++ ++ ++ ++----- Names of time zone rules ----- ++ ++Each of the database's time zone rules has a unique name. ++Inexperienced users are not expected to select these names unaided. ++Distributors should provide documentation and/or a simple selection ++interface that explains the names; for one example, see the 'tzselect' ++program in the tz code. The Unicode Common Locale Data Repository ++<http://cldr.unicode.org/> contains data that may be useful for other ++selection interfaces. ++ ++The time zone rule naming conventions attempt to strike a balance ++among the following goals: ++ ++ * Uniquely identify every region where clocks have agreed since 1970. ++ This is essential for the intended use: static clocks keeping local ++ civil time. ++ ++ * Indicate to experts where that region is. ++ ++ * Be robust in the presence of political changes. For example, names ++ of countries are ordinarily not used, to avoid incompatibilities ++ when countries change their name (e.g. Zaire->Congo) or when ++ locations change countries (e.g. Hong Kong from UK colony to ++ China). ++ ++ * Be portable to a wide variety of implementations. ++ ++ * Use a consistent naming conventions over the entire world. ++ ++Names normally have the form AREA/LOCATION, where AREA is the name ++of a continent or ocean, and LOCATION is the name of a specific ++location within that region. North and South America share the same ++area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York', ++and 'Pacific/Honolulu'. ++ ++Here are the general rules used for choosing location names, ++in decreasing order of importance: ++ ++ Use only valid POSIX file name components (i.e., the parts of ++ names other than '/'). Do not use the file name ++ components '.' and '..'. Within a file name component, ++ use only ASCII letters, '.', '-' and '_'. Do not use ++ digits, as that might create an ambiguity with POSIX ++ TZ strings. A file name component must not exceed 14 ++ characters or start with '-'. E.g., prefer 'Brunei' ++ to 'Bandar_Seri_Begawan'. Exceptions: see the discussion ++ of legacy names below. ++ A name must not be empty, or contain '//', or start or end with '/'. ++ Do not use names that differ only in case. Although the reference ++ implementation is case-sensitive, some other implementations ++ are not, and they would mishandle names differing only in case. ++ If one name A is an initial prefix of another name AB (ignoring case), ++ then B must not start with '/', as a regular file cannot have ++ the same name as a directory in POSIX. For example, ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ Uninhabited regions like the North Pole and Bouvet Island ++ do not need locations, since local time is not defined there. ++ There should typically be at least one name for each ISO 3166-1 ++ officially assigned two-letter code for an inhabited country ++ or territory. ++ If all the clocks in a region have agreed since 1970, ++ don't bother to include more than one location ++ even if subregions' clocks disagreed before 1970. ++ Otherwise these tables would become annoyingly large. ++ If a name is ambiguous, use a less ambiguous alternative; ++ e.g. many cities are named San José and Georgetown, so ++ prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'. ++ Keep locations compact. Use cities or small islands, not countries ++ or regions, so that any future time zone changes do not split ++ locations into different time zones. E.g. prefer 'Paris' ++ to 'France', since France has had multiple time zones. ++ Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and ++ prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'. ++ The POSIX file name restrictions encourage this rule. ++ Use the most populous among locations in a zone, ++ e.g. prefer 'Shanghai' to 'Beijing'. Among locations with ++ similar populations, pick the best-known location, ++ e.g. prefer 'Rome' to 'Milan'. ++ Use the singular form, e.g. prefer 'Canary' to 'Canaries'. ++ Omit common suffixes like '_Islands' and '_City', unless that ++ would lead to ambiguity. E.g. prefer 'Cayman' to ++ 'Cayman_Islands' and 'Guatemala' to 'Guatemala_City', ++ but prefer 'Mexico_City' to 'Mexico' because the country ++ of Mexico has several time zones. ++ Use '_' to represent a space. ++ Omit '.' from abbreviations in names, e.g. prefer 'St_Helena' ++ to 'St._Helena'. ++ Do not change established names if they only marginally ++ violate the above rules. For example, don't change ++ the existing name 'Rome' to 'Milan' merely because ++ Milan's population has grown to be somewhat greater ++ than Rome's. ++ If a name is changed, put its old spelling in the 'backward' file. ++ This means old spellings will continue to work. ++ ++The file 'zone1970.tab' lists geographical locations used to name time ++zone rules. It is intended to be an exhaustive list of names for ++geographic regions as described above; this is a subset of the names ++in the data. Although a 'zone1970.tab' location's longitude ++corresponds to its LMT offset with one hour for every 15 degrees east ++longitude, this relationship is not exact. ++ ++Older versions of this package used a different naming scheme, ++and these older names are still supported. ++See the file 'backward' for most of these older names ++(e.g., 'US/Eastern' instead of 'America/New_York'). ++The other old-fashioned names still supported are ++'WET', 'CET', 'MET', and 'EET' (see the file 'europe'). ++ ++Older versions of this package defined legacy names that are ++incompatible with the first rule of location names, but which are ++still supported. These legacy names are mostly defined in the file ++'etcetera'. Also, the file 'backward' defines the legacy names ++'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file ++'northamerica' defines the legacy names 'EST5EDT', 'CST6CDT', ++'MST7MDT', and 'PST8PDT'. ++ ++Excluding 'backward' should not affect the other data. If ++'backward' is excluded, excluding 'etcetera' should not affect the ++remaining data. ++ ++ ++----- Time zone abbreviations ----- ++ ++When this package is installed, it generates time zone abbreviations ++like 'EST' to be compatible with human tradition and POSIX. ++Here are the general rules used for choosing time zone abbreviations, ++in decreasing order of importance: ++ ++ Use three or more characters that are ASCII alphanumerics or '+' or '-'. ++ Previous editions of this database also used characters like ++ ' ' and '?', but these characters have a special meaning to ++ the shell and cause commands like ++ set `date` ++ to have unexpected effects. ++ Previous editions of this rule required upper-case letters, ++ but the Congressman who introduced Chamorro Standard Time ++ preferred "ChST", so lower-case letters are now allowed. ++ Also, POSIX from 2001 on relaxed the rule to allow '-', '+', ++ and alphanumeric characters from the portable character set ++ in the current locale. In practice ASCII alphanumerics and ++ '+' and '-' are safe in all locales. ++ ++ In other words, in the C locale the POSIX extended regular ++ expression [-+[:alnum:]]{3,} should match the abbreviation. ++ This guarantees that all abbreviations could have been ++ specified by a POSIX TZ string. ++ ++ Use abbreviations that are in common use among English-speakers, ++ e.g. 'EST' for Eastern Standard Time in North America. ++ We assume that applications translate them to other languages ++ as part of the normal localization process; for example, ++ a French application might translate 'EST' to 'HNE'. ++ ++ For zones whose times are taken from a city's longitude, use the ++ traditional xMT notation, e.g. 'PMT' for Paris Mean Time. ++ The only name like this in current use is 'GMT'. ++ ++ Use 'LMT' for local mean time of locations before the introduction ++ of standard time; see "Scope of the tz database". ++ ++ If there is no common English abbreviation, use numeric offsets like ++ -05 and +0830 that are generated by zic's %z notation. ++ ++ [The remaining guidelines predate the introduction of %z. ++ They are problematic as they mean tz data entries invent ++ notation rather than record it. These guidelines are now ++ deprecated and the plan is to gradually move to %z for ++ inhabited locations and to "-00" for uninhabited locations.] ++ ++ If there is no common English abbreviation, abbreviate the English ++ translation of the usual phrase used by native speakers. ++ If this is not available or is a phrase mentioning the country ++ (e.g. "Cape Verde Time"), then: ++ ++ When a country is identified with a single or principal zone, ++ append 'T' to the country's ISO code, e.g. 'CVT' for ++ Cape Verde Time. For summer time append 'ST'; ++ for double summer time append 'DST'; etc. ++ Otherwise, take the first three letters of an English place ++ name identifying each zone and append 'T', 'ST', etc. ++ as before; e.g. 'VLAST' for VLAdivostok Summer Time. ++ ++ Use UT (with time zone abbreviation '-00') for locations while ++ uninhabited. The leading '-' is a flag that the time ++ zone is in some sense undefined; this notation is ++ derived from Internet RFC 3339. ++ ++Application writers should note that these abbreviations are ambiguous ++in practice: e.g. 'CST' has a different meaning in China than ++it does in the United States. In new applications, it's often better ++to use numeric UT offsets like '-0600' instead of time zone ++abbreviations like 'CST'; this avoids the ambiguity. ++ ++ ++----- Accuracy of the tz database ----- ++ ++The tz database is not authoritative, and it surely has errors. ++Corrections are welcome and encouraged; see the file CONTRIBUTING. ++Users requiring authoritative data should consult national standards ++bodies and the references cited in the database's comments. ++ ++Errors in the tz database arise from many sources: ++ ++ * The tz database predicts future time stamps, and current predictions ++ will be incorrect after future governments change the rules. ++ For example, if today someone schedules a meeting for 13:00 next ++ October 1, Casablanca time, and tomorrow Morocco changes its ++ daylight saving rules, software can mess up after the rule change ++ if it blithely relies on conversions made before the change. ++ ++ * The pre-1970 entries in this database cover only a tiny sliver of how ++ clocks actually behaved; the vast majority of the necessary ++ information was lost or never recorded. Thousands more zones would ++ be needed if the tz database's scope were extended to cover even ++ just the known or guessed history of standard time; for example, ++ the current single entry for France would need to split into dozens ++ of entries, perhaps hundreds. And in most of the world even this ++ approach would be misleading due to widespread disagreement or ++ indifference about what times should be observed. In her 2015 book ++ "The Global Transformation of Time, 1870-1950", Vanessa Ogle writes ++ "Outside of Europe and North America there was no system of time ++ zones at all, often not even a stable landscape of mean times, ++ prior to the middle decades of the twentieth century". See: ++ Timothy Shenk, Booked: A Global History of Time. Dissent 2015-12-17 ++ https://www.dissentmagazine.org/blog/booked-a-global-history-of-time-vanessa-ogle ++ ++ * Most of the pre-1970 data entries come from unreliable sources, often ++ astrology books that lack citations and whose compilers evidently ++ invented entries when the true facts were unknown, without ++ reporting which entries were known and which were invented. ++ These books often contradict each other or give implausible entries, ++ and on the rare occasions when they are checked they are ++ typically found to be incorrect. ++ ++ * For the UK the tz database relies on years of first-class work done by ++ Joseph Myers and others; see <http://www.polyomino.org.uk/british-time/>. ++ Other countries are not done nearly as well. ++ ++ * Sometimes, different people in the same city would maintain clocks ++ that differed significantly. Railway time was used by railroad ++ companies (which did not always agree with each other), ++ church-clock time was used for birth certificates, etc. ++ Often this was merely common practice, but sometimes it was set by law. ++ For example, from 1891 to 1911 the UT offset in France was legally ++ 0:09:21 outside train stations and 0:04:21 inside. ++ ++ * Although a named location in the tz database stands for the ++ containing region, its pre-1970 data entries are often accurate for ++ only a small subset of that region. For example, Europe/London ++ stands for the United Kingdom, but its pre-1847 times are valid ++ only for locations that have London's exact meridian, and its 1847 ++ transition to GMT is known to be valid only for the L&NW and the ++ Caledonian railways. ++ ++ * The tz database does not record the earliest time for which a zone's ++ data entries are thereafter valid for every location in the region. ++ For example, Europe/London is valid for all locations in its ++ region after GMT was made the standard time, but the date of ++ standardization (1880-08-02) is not in the tz database, other than ++ in commentary. For many zones the earliest time of validity is ++ unknown. ++ ++ * The tz database does not record a region's boundaries, and in many ++ cases the boundaries are not known. For example, the zone ++ America/Kentucky/Louisville represents a region around the city of ++ Louisville, the boundaries of which are unclear. ++ ++ * Changes that are modeled as instantaneous transitions in the tz ++ database were often spread out over hours, days, or even decades. ++ ++ * Even if the time is specified by law, locations sometimes ++ deliberately flout the law. ++ ++ * Early timekeeping practices, even assuming perfect clocks, were ++ often not specified to the accuracy that the tz database requires. ++ ++ * Sometimes historical timekeeping was specified more precisely ++ than what the tz database can handle. For example, from 1909 to ++ 1937 Netherlands clocks were legally UT +00:19:32.13, but the tz ++ database cannot represent the fractional second. ++ ++ * Even when all the timestamp transitions recorded by the tz database ++ are correct, the tz rules that generate them may not faithfully ++ reflect the historical rules. For example, from 1922 until World ++ War II the UK moved clocks forward the day following the third ++ Saturday in April unless that was Easter, in which case it moved ++ clocks forward the previous Sunday. Because the tz database has no ++ way to specify Easter, these exceptional years are entered as ++ separate tz Rule lines, even though the legal rules did not change. ++ ++ * The tz database models pre-standard time using the proleptic Gregorian ++ calendar and local mean time (LMT), but many people used other ++ calendars and other timescales. For example, the Roman Empire used ++ the Julian calendar, and had 12 varying-length daytime hours with a ++ non-hour-based system at night. ++ ++ * Early clocks were less reliable, and data entries do not represent ++ this unreliability. ++ ++ * As for leap seconds, civil time was not based on atomic time before ++ 1972, and we don't know the history of earth's rotation accurately ++ enough to map SI seconds to historical solar time to more than ++ about one-hour accuracy. See: Morrison LV, Stephenson FR. ++ Historical values of the Earth's clock error Delta T and the ++ calculation of eclipses. J Hist Astron. 2004;35:327-36 ++ <http://adsabs.harvard.edu/full/2004JHA....35..327M>; ++ Historical values of the Earth's clock error. J Hist Astron. 2005;36:339 ++ <http://adsabs.harvard.edu/full/2005JHA....36..339M>. ++ ++ * The relationship between POSIX time (that is, UTC but ignoring leap ++ seconds) and UTC is not agreed upon after 1972. Although the POSIX ++ clock officially stops during an inserted leap second, at least one ++ proposed standard has it jumping back a second instead; and in ++ practice POSIX clocks more typically either progress glacially during ++ a leap second, or are slightly slowed while near a leap second. ++ ++ * The tz database does not represent how uncertain its information is. ++ Ideally it would contain information about when data entries are ++ incomplete or dicey. Partial temporal knowledge is a field of ++ active research, though, and it's not clear how to apply it here. ++ ++In short, many, perhaps most, of the tz database's pre-1970 and future ++time stamps are either wrong or misleading. Any attempt to pass the ++tz database off as the definition of time should be unacceptable to ++anybody who cares about the facts. In particular, the tz database's ++LMT offsets should not be considered meaningful, and should not prompt ++creation of zones merely because two locations differ in LMT or ++transitioned to standard time at different dates. ++ ++ ++----- Time and date functions ----- ++ ++The tz code contains time and date functions that are upwards ++compatible with those of POSIX. ++ ++POSIX has the following properties and limitations. ++ ++* In POSIX, time display in a process is controlled by the ++ environment variable TZ. Unfortunately, the POSIX TZ string takes ++ a form that is hard to describe and is error-prone in practice. ++ Also, POSIX TZ strings can't deal with other (for example, Israeli) ++ daylight saving time rules, or situations where more than two ++ time zone abbreviations are used in an area. ++ ++ The POSIX TZ string takes the following form: ++ ++ stdoffset[dst[offset][,date[/time],date[/time]]] ++ ++ where: ++ ++ std and dst ++ are 3 or more characters specifying the standard ++ and daylight saving time (DST) zone names. ++ Starting with POSIX.1-2001, std and dst may also be ++ in a quoted form like "<UTC+10>"; this allows ++ "+" and "-" in the names. ++ offset ++ is of the form '[+-]hh:[mm[:ss]]' and specifies the ++ offset west of UT. 'hh' may be a single digit; 0<=hh<=24. ++ The default DST offset is one hour ahead of standard time. ++ date[/time],date[/time] ++ specifies the beginning and end of DST. If this is absent, ++ the system supplies its own rules for DST, and these can ++ differ from year to year; typically US DST rules are used. ++ time ++ takes the form 'hh:[mm[:ss]]' and defaults to 02:00. ++ This is the same format as the offset, except that a ++ leading '+' or '-' is not allowed. ++ date ++ takes one of the following forms: ++ Jn (1<=n<=365) ++ origin-1 day number not counting February 29 ++ n (0<=n<=365) ++ origin-0 day number counting February 29 if present ++ Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) ++ for the dth day of week n of month m of the year, ++ where week 1 is the first week in which day d appears, ++ and '5' stands for the last week in which day d appears ++ (which may be either the 4th or 5th week). ++ Typically, this is the only useful form; ++ the n and Jn forms are rarely used. ++ ++ Here is an example POSIX TZ string, for US Pacific time using rules ++ appropriate from 1987 through 2006: ++ ++ TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00' ++ ++ This POSIX TZ string is hard to remember, and mishandles time stamps ++ before 1987 and after 2006. With this package you can use this ++ instead: ++ ++ TZ='America/Los_Angeles' ++ ++* POSIX does not define the exact meaning of TZ values like "EST5EDT". ++ Typically the current US DST rules are used to interpret such values, ++ but this means that the US DST rules are compiled into each program ++ that does time conversion. This means that when US time conversion ++ rules change (as in the United States in 1987), all programs that ++ do time conversion must be recompiled to ensure proper results. ++ ++* The TZ environment variable is process-global, which makes it hard ++ to write efficient, thread-safe applications that need access ++ to multiple time zones. ++ ++* In POSIX, there's no tamper-proof way for a process to learn the ++ system's best idea of local wall clock. (This is important for ++ applications that an administrator wants used only at certain times - ++ without regard to whether the user has fiddled the "TZ" environment ++ variable. While an administrator can "do everything in UTC" to get ++ around the problem, doing so is inconvenient and precludes handling ++ daylight saving time shifts - as might be required to limit phone ++ calls to off-peak hours.) ++ ++* POSIX provides no convenient and efficient way to determine the UT ++ offset and time zone abbreviation of arbitrary time stamps, ++ particularly for time zone settings that do not fit into the ++ POSIX model. ++ ++* POSIX requires that systems ignore leap seconds. ++ ++* The tz code attempts to support all the time_t implementations ++ allowed by POSIX. The time_t type represents a nonnegative count of ++ seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds. ++ In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit ++ signed time_t values stop working after 2038-01-19 03:14:07 UTC, so ++ new implementations these days typically use a signed 64-bit integer. ++ Unsigned 32-bit integers are used on one or two platforms, ++ and 36-bit and 40-bit integers are also used occasionally. ++ Although earlier POSIX versions allowed time_t to be a ++ floating-point type, this was not supported by any practical ++ systems, and POSIX.1-2013 and the tz code both require time_t ++ to be an integer type. ++ ++These are the extensions that have been made to the POSIX functions: ++ ++* The "TZ" environment variable is used in generating the name of a file ++ from which time zone information is read (or is interpreted a la ++ POSIX); "TZ" is no longer constrained to be a three-letter time zone ++ name followed by a number of hours and an optional three-letter ++ daylight time zone name. The daylight saving time rules to be used ++ for a particular time zone are encoded in the time zone file; ++ the format of the file allows U.S., Australian, and other rules to be ++ encoded, and allows for situations where more than two time zone ++ abbreviations are used. ++ ++ It was recognized that allowing the "TZ" environment variable to ++ take on values such as "America/New_York" might cause "old" programs ++ (that expect "TZ" to have a certain form) to operate incorrectly; ++ consideration was given to using some other environment variable ++ (for example, "TIMEZONE") to hold the string used to generate the ++ time zone information file name. In the end, however, it was decided ++ to continue using "TZ": it is widely used for time zone purposes; ++ separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; ++ and systems where "new" forms of "TZ" might cause problems can simply ++ use TZ values such as "EST5EDT" which can be used both by ++ "new" programs (a la POSIX) and "old" programs (as zone names and ++ offsets). ++ ++* The code supports platforms with a UT offset member in struct tm, ++ e.g., tm_gmtoff. ++ ++* The code supports platforms with a time zone abbreviation member in ++ struct tm, e.g., tm_zone. ++ ++* Since the "TZ" environment variable can now be used to control time ++ conversion, the "daylight" and "timezone" variables are no longer ++ needed. (These variables are defined and set by "tzset"; however, their ++ values will not be used by "localtime.") ++ ++* Functions tzalloc, tzfree, localtime_rz, and mktime_z for ++ more-efficient thread-safe applications that need to use ++ multiple time zones. The tzalloc and tzfree functions ++ allocate and free objects of type timezone_t, and localtime_rz ++ and mktime_z are like localtime_r and mktime with an extra ++ timezone_t argument. The functions were inspired by NetBSD. ++ ++* A function "tzsetwall" has been added to arrange for the system's ++ best approximation to local wall clock time to be delivered by ++ subsequent calls to "localtime." Source code for portable ++ applications that "must" run on local wall clock time should call ++ "tzsetwall();" if such code is moved to "old" systems that don't ++ provide tzsetwall, you won't be able to generate an executable program. ++ (These time zone functions also arrange for local wall clock time to be ++ used if tzset is called - directly or indirectly - and there's no "TZ" ++ environment variable; portable applications should not, however, rely ++ on this behavior since it's not the way SVR2 systems behave.) ++ ++* Negative time_t values are supported, on systems where time_t is signed. ++ ++* These functions can account for leap seconds, thanks to Bradley White. ++ ++Points of interest to folks with other systems: ++ ++* Code compatible with this package is already part of many platforms, ++ including GNU/Linux, Android, the BSDs, Chromium OS, Cygwin, AIX, iOS, ++ BlackBery 10, macOS, Microsoft Windows, OpenVMS, and Solaris. ++ On such hosts, the primary use of this package ++ is to update obsolete time zone rule tables. ++ To do this, you may need to compile the time zone compiler ++ 'zic' supplied with this package instead of using the system 'zic', ++ since the format of zic's input is occasionally extended, ++ and a platform may still be shipping an older zic. ++ ++* The UNIX Version 7 "timezone" function is not present in this package; ++ it's impossible to reliably map timezone's arguments (a "minutes west ++ of GMT" value and a "daylight saving time in effect" flag) to a ++ time zone abbreviation, and we refuse to guess. ++ Programs that in the past used the timezone function may now examine ++ tzname[localtime(&clock)->tm_isdst] to learn the correct time ++ zone abbreviation to use. Alternatively, use ++ localtime(&clock)->tm_zone if this has been enabled. ++ ++* The 4.2BSD gettimeofday function is not used in this package. ++ This formerly let users obtain the current UTC offset and DST flag, ++ but this functionality was removed in later versions of BSD. ++ ++* In SVR2, time conversion fails for near-minimum or near-maximum ++ time_t values when doing conversions for places that don't use UT. ++ This package takes care to do these conversions correctly. ++ A comment in the source code tells how to get compatibly wrong ++ results. ++ ++The functions that are conditionally compiled if STD_INSPIRED is defined ++should, at this point, be looked on primarily as food for thought. They are ++not in any sense "standard compatible" - some are not, in fact, specified in ++*any* standard. They do, however, represent responses of various authors to ++standardization proposals. ++ ++Other time conversion proposals, in particular the one developed by folks at ++Hewlett Packard, offer a wider selection of functions that provide capabilities ++beyond those provided here. The absence of such functions from this package ++is not meant to discourage the development, standardization, or use of such ++functions. Rather, their absence reflects the decision to make this package ++contain valid extensions to POSIX, to ensure its broad acceptability. If ++more powerful time conversion functions can be standardized, so much the ++better. ++ ++ ++----- Interface stability ----- ++ ++The tz code and data supply the following interfaces: ++ ++ * A set of zone names as per "Names of time zone rules" above. ++ ++ * Library functions described in "Time and date functions" above. ++ ++ * The programs tzselect, zdump, and zic, documented in their man pages. ++ ++ * The format of zic input files, documented in the zic man page. ++ ++ * The format of zic output files, documented in the tzfile man page. ++ ++ * The format of zone table files, documented in zone1970.tab. ++ ++ * The format of the country code file, documented in iso3166.tab. ++ ++When these interfaces are changed, an effort is made to preserve ++backward compatibility. For example, tz data files typically do not ++rely on recently-added zic features, so that users can run older zic ++versions to process newer data files. ++ ++Interfaces not listed above are less stable. For example, users ++should not rely on particular UT offsets or abbreviations for time ++stamps, as data entries are often based on guesswork and these guesses ++may be corrected or improved. ++ ++ ++----- Calendrical issues ----- ++ ++Calendrical issues are a bit out of scope for a time zone database, ++but they indicate the sort of problems that we would run into if we ++extended the time zone database further into the past. An excellent ++resource in this area is Nachum Dershowitz and Edward M. Reingold, ++Calendrical Calculations: Third Edition, Cambridge University Press (2008) ++<http://emr.cs.iit.edu/home/reingold/calendar-book/third-edition/>. ++Other information and sources are given below. They sometimes disagree. ++ ++ ++France ++ ++Gregorian calendar adopted 1582-12-20. ++French Revolutionary calendar used 1793-11-24 through 1805-12-31, ++and (in Paris only) 1871-05-06 through 1871-05-23. ++ ++ ++Russia ++ ++From Chris Carrier (1996-12-02): ++On 1929-10-01 the Soviet Union instituted an "Eternal Calendar" ++with 30-day months plus 5 holidays, with a 5-day week. ++On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the ++Gregorian calendar while retaining the 6-day week; on 1940-06-27 it ++reverted to the 7-day week. With the 6-day week the usual days ++off were the 6th, 12th, 18th, 24th and 30th of the month. ++(Source: Evitiar Zerubavel, _The Seven Day Circle_) ++ ++ ++Mark Brader reported a similar story in "The Book of Calendars", edited ++by Frank Parise (1982, Facts on File, ISBN 0-8719-6467-8), page 377.

Grotefend, _Taschenbuch der Zeitrechnung des deutschen ++Mittelalters und der Neuzeit_, herausgegeben von Dr. O. Grotefend ++(Hannover: Hahnsche Buchhandlung, 1941), pp. 26-28. ++ ++ ++----- Time and time zones on Mars ----- ++ ++Some people's work schedules use Mars time. Jet Propulsion Laboratory ++(JPL) coordinators have kept Mars time on and off at least since 1997 ++for the Mars Pathfinder mission. Some of their family members have ++also adapted to Mars time. Dozens of special Mars watches were built ++for JPL workers who kept Mars time during the Mars Exploration ++Rovers mission (2004). These timepieces look like normal Seikos and ++Citizens but use Mars seconds rather than terrestrial seconds. ++ ++A Mars solar day is called a "sol" and has a mean period equal to ++about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is ++divided into a conventional 24-hour clock, so each Mars second equals ++about 1.02749125 terrestrial seconds. ++ ++The prime meridian of Mars goes through the center of the crater ++Airy-0, named in honor of the British astronomer who built the ++Greenwich telescope that defines Earth's prime meridian. Mean solar ++time on the Mars prime meridian is called Mars Coordinated Time (MTC). ++ ++Each landed mission on Mars has adopted a different reference for ++solar time keeping, so there is no real standard for Mars time zones. ++For example, the Mars Exploration Rover project (2004) defined two ++time zones "Local Solar Time A" and "Local Solar Time B" for its two ++missions, each zone designed so that its time equals local true solar ++time at approximately the middle of the nominal mission. Such a "time ++zone" is not particularly suited for any application other than the ++mission itself. ++ ++Many calendars have been proposed for Mars, but none have achieved ++wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a ++sequential count of Mars solar days elapsed since about 1873-12-29 ++12:00 GMT. ++ ++The tz database does not currently support Mars time, but it is ++documented here in the hopes that support will be added eventually. ++ ++Sources: ++ ++Michael Allison and Robert Schmunk, ++"Technical Notes on Mars Solar Time as Adopted by the Mars24 Sunclock" ++<http://www.giss.nasa.gov/tools/mars24/help/notes.html> (2012-08-08). ++ ++Jia-Rui Chong, "Workdays Fit for a Martian", Los Angeles Times ++<http://articles.latimes.com/2004/jan/14/science/sci-marstime14> ++(2004-01-14), pp A1, A20-A21. ++ ++Tom Chmielewski, "Jet Lag Is Worse on Mars", The Atlantic (2015-02-26) ++<http://www.theatlantic.com/technology/archive/2015/02/jet-lag-is-worse-on-mars/386033/> ++ ++----- ++ ++This file is in the public domain, so clarified as of 2009-05-17 by ++Arthur David Olson. ++ ++----- ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/africa.orig ++++ contrib/tzdata/africa +@@ -343,6 +343,12 @@ + # decision to abandon DST permanently.

This arranges for the functions ++# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", ++# "posix2time", and "time2posix" to be added to the time conversion library. ++# "tzsetwall" is like "tzset" except that it arranges for local wall clock ++# time (rather than the time specified in the TZ environment variable) ++# to be used. ++# "offtime" is like "gmtime" except that it accepts a second (long) argument ++# that gives an offset to add to the time_t when converting it. ++# "timelocal" is equivalent to "mktime". ++# "timegm" is like "timelocal" except that it turns a struct tm into ++# a time_t using UT (rather than local time as "timelocal" does). ++# "timeoff" is like "timegm" except that it accepts a second (long) argument ++# that gives an offset to use when converting to a time_t. ++# "posix2time" and "time2posix" are described in an included manual page. ++# X3J11's work does not describe any of these functions. ++# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. ++# These functions may well disappear in future releases of the time ++# conversion package. ++# ++# If you don't want functions that were inspired by NetBSD, add ++# -DNETBSD_INSPIRED=0 ++# to the end of the "CFLAGS=" line. Otherwise, the functions ++# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the ++# time library, and if STD_INSPIRED is also defined the functions ++# "posix2time_z" and "time2posix_z" are added as well. ++# The functions ending in "_z" (or "_rz") are like their unsuffixed ++# (or suffixed-by-"_r") counterparts, except with an extra first ++# argument of opaque type timezone_t that specifies the time zone. ++# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. ++# ++# If you want to allocate state structures in localtime, add ++# -DALL_STATE ++# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. ++# ++# If you want an "altzone" variable (a la System V Release 3.1), add ++# -DALTZONE ++# to the end of the "CFLAGS=" line. ++# This variable is not described in X3J11's work. ++# ++# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put ++# out by the National Institute of Standards and Technology ++# which claims to test C and Posix conformance.

The affected ++ zones are Europe/Kirov, Europe/Moscow, Europe/Samara, and ++ Europe/Ulyanovsk. (Thanks to Alexander Belopolsky.) ++ ++ Changes to past and future time zone abbreviations ++ ++ The Factory zone now uses the time zone abbreviation -00 instead ++ of a long English-language string, as -00 is now the normal way to ++ represent an undefined time zone. ++ ++ Several zones in Antarctica and the former Soviet Union, along ++ with zones intended for ships at sea that cannot use POSIX TZ ++ strings, now use numeric time zone abbreviations instead of ++ invented or obsolete alphanumeric abbreviations. The affected ++ zones are Antarctica/Casey, Antarctica/Davis, ++ Antarctica/DumontDUrville, Antarctica/Mawson, Antarctica/Rothera, ++ Antarctica/Syowa, Antarctica/Troll, Antarctica/Vostok, ++ Asia/Anadyr, Asia/Ashgabat, Asia/Baku, Asia/Bishkek, Asia/Chita, ++ Asia/Dushanbe, Asia/Irkutsk, Asia/Kamchatka, Asia/Khandyga, ++ Asia/Krasnoyarsk, Asia/Magadan, Asia/Omsk, Asia/Sakhalin, ++ Asia/Samarkand, Asia/Srednekolymsk, Asia/Tashkent, Asia/Tbilisi, ++ Asia/Ust-Nera, Asia/Vladivostok, Asia/Yakutsk, Asia/Yekaterinburg, ++ Asia/Yerevan, Etc/GMT-14, Etc/GMT-13, Etc/GMT-12, Etc/GMT-11, ++ Etc/GMT-10, Etc/GMT-9, Etc/GMT-8, Etc/GMT-7, Etc/GMT-6, Etc/GMT-5, ++ Etc/GMT-4, Etc/GMT-3, Etc/GMT-2, Etc/GMT-1, Etc/GMT+1, Etc/GMT+2, ++ Etc/GMT+3, Etc/GMT+4, Etc/GMT+5, Etc/GMT+6, Etc/GMT+7, Etc/GMT+8, ++ Etc/GMT+9, Etc/GMT+10, Etc/GMT+11, Etc/GMT+12, Europe/Kaliningrad, ++ Europe/Minsk, Europe/Samara, Europe/Volgograd, and ++ Indian/Kerguelen. For Europe/Moscow the invented abbreviation MSM ++ was replaced by +05, whereas MSK and MSD were kept as they are not ++ our invention and are widely used. ++ ++ Changes to zone names ++ ++ Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link. ++ (Thanks to David Massoud.) ++ ++ Changes to code ++ ++ zic no longer generates binary files containing POSIX TZ-like ++ strings that disagree with the local time type after the last ++ explicit transition in the data. This fixes a bug with ++ Africa/Casablanca and Africa/El_Aaiun in some year-2037 time ++ stamps on the reference platform. (Thanks to Alexander Belopolsky ++ for reporting the bug and suggesting a way forward.) ++ ++ If the installed localtime and/or posixrules files are symbolic ++ links, zic now keeps them symbolic links when updating them, for ++ compatibility with platforms like OpenSUSE where other programs ++ configure these files as symlinks. ++ ++ zic now avoids hard linking to symbolic links, avoids some ++ unnecessary mkdir and stat system calls, and uses shorter file ++ names internally. ++ ++ zdump has a new -i option to generate transitions in a ++ more-compact but still human-readable format. This option is ++ experimental, and the output format may change in future versions. ++ (Thanks to Jon Skeet for suggesting that an option was needed, ++ and thanks to Tim Parenti and Chris Rovick for further comments.) ++ ++ Changes to build procedure ++ ++ An experimental distribution format is available, in addition ++ to the traditional format which will continue to be distributed. ++ The new format is a tarball tzdb-VERSION.tar.lz with signature ++ file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory ++ tzdb-VERSION containing the code and data of the traditional ++ two-tarball format, along with extra data that may be useful. ++ (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others ++ for comments about the experimental format.) ++ ++ The release version number is now more accurate in the usual case ++ where releases are built from a Git repository. For example, if ++ 23 commits and some working-file changes have been made since ++ release 2016g, the version number is now something like ++ '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. ++ Official releases uses the same version number format as before, ++ e.g., '2016g'. To support the more-accurate version number, its ++ specification has moved from a line in the Makefile to a new ++ source file 'version'. ++ ++ The experimental distribution contains a file to2050.tzs that ++ contains what should be the output of 'zdump -i -c 2050' on ++ primary zones. If this file is available, 'make check' now checks ++ that zdump generates this output. ++ ++ 'make check_web' now works on Fedora-like distributions. ++ ++ Changes to documentation and commentary ++ ++ tzfile.5 now documents the new restriction on POSIX TZ-like ++ strings that is now implemented by zic. ++ ++ Comments now cite URLs for some 1917-1921 Russian DST decrees. ++ (Thanks to Alexander Belopolsky.) ++ ++ tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J ++ (thanks to Meno Hochschild) and ThreeTen-Extra, and its ++ description of Java 8 has been brought up to date (thanks to ++ Stephen Colebourne). Its description of local time on Mars has ++ been updated to match current practice, and URLs have been updated ++ and some obsolete ones removed. ++ ++ ++Release 2016f - 2016-07-05 16:26:51 +0200 ++ ++ Changes affecting future time stamps ++ ++ The Egyptian government changed its mind on short notice, and ++ Africa/Cairo will not introduce DST starting 2016-07-07 after all. ++ (Thanks to Mina Samuel.) ++ ++ Asia/Novosibirsk switches from +06 to +07 on 2016-07-24 at 02:00. ++ (Thanks to Stepan Golosunov.) ++ ++ Changes to past and future time stamps ++ ++ Asia/Novokuznetsk and Asia/Novosibirsk now use numeric time zone ++ abbreviations instead of invented ones. ++ ++ Changes affecting past time stamps ++ ++ Europe/Minsk's 1992-03-29 spring-forward transition was at 02:00 not 00:00. ++ (Thanks to Stepan Golosunov.) ++ ++ ++Release 2016e - 2016-06-14 08:46:16 -0700 ++ ++ Changes affecting future time stamps ++ ++ Africa/Cairo observes DST in 2016 from July 7 to the end of October. ++ Guess October 27 and 24:00 transitions.

This is inspired by Internet ++ RFC 3339 and is more consistent with numeric time zone ++ abbreviations already used elsewhere. The change affects several ++ arctic and antarctic locations, e.g., America/Cambridge_Bay before ++ 1920 and Antarctica/Troll before 2005. ++ ++ Asia/Baku's 1992-09-27 transition from +04 (DST) to +04 (non-DST) was ++ at 03:00, not 23:00 the previous day.

The new file is not recommended ++ for ordinary use and its entries are not installed by default. ++ (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and ++ Isle of Man entries.) ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Bangui, Africa/Brazzaville, ++ Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, ++ Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. ++ ++ Changes affecting code ++ ++ Unless NETBSD_INSPIRED is defined to 0, the tz library now ++ supplies functions for creating and using objects that represent ++ time zones. The new functions are tzalloc, tzfree, localtime_rz, ++ mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and ++ time2posix_z. They are intended for performance: for example, ++ localtime_rz (unlike localtime_r) is trivially thread-safe without ++ locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired ++ functions, and to Alan Barrett and Jonathan Lennox for helping to ++ debug the change.) ++ ++ zdump now builds with the tz library unless USE_LTZ is defined to 0, ++ This lets zdump use tz features even if the system library lacks them. ++ To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 ++ TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. ++ ++ zdump now uses localtime_rz if available, as it's significantly faster, ++ and it can help zdump better diagnose invalid time zone names. ++ Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ ++ defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is ++ not available, zdump now uses localtime_r and tzset if available, ++ as this is a bit cleaner and faster than plain localtime. Compile ++ with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system ++ lacks these two functions. ++ ++ If THREAD_SAFE is defined to 1, the tz library is now thread-safe. ++ Although not needed for tz's own applications, which are single-threaded, ++ this supports POSIX better if the tz library is used in multithreaded apps. ++ ++ Some crashes have been fixed when zdump or the tz library is given ++ invalid or outlandish input. ++ ++ The tz library no longer mishandles leap seconds on platforms with ++ unsigned time_t in time zones that lack ordinary transitions after 1970. ++ ++ The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not ++ already defined, to make it easier to configure on common platforms. ++ Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. ++ ++ Unless the new macro UNINIT_TRAP is defined to 1, the tz code now ++ assumes that reading uninitialized memory yields garbage values ++ but does not cause other problems such as traps. ++ ++ If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now ++ more likely to guess right for ambiguous time stamps near ++ transitions where tm_isdst does not change. ++ ++ If HAVE_STRFTIME_L is defined to 1, the tz library now defines ++ strftime_l for compatibility with recent versions of POSIX. ++ Only the C locale is supported, though. HAVE_STRFTIME_L defaults ++ to 1 on recent POSIX versions, and to 0 otherwise. ++ ++ tzselect -c now uses a hybrid distance measure that works better ++ in Africa. (Thanks to Alan Barrett for noting the problem.) ++ ++ The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, ++ or when time_tz is defined. ++ ++ When HAVE_UTMPX_H is set the 'date' command now builds on systems ++ whose <utmpx.h> file does not define WTMPX_FILE, and when setting ++ the date it updates the wtmpx file if _PATH_WTMPX is defined. ++ This affects GNU/Linux and similar systems. ++ ++ For easier maintenance later, some C code has been simplified, ++ some lint has been removed, and the code has been tweaked so that ++ plain 'make' is more likely to work. ++ ++ The C type 'bool' is now used for boolean values, instead of 'int'. ++ ++ The long-obsolete LOCALE_HOME code has been removed. ++ ++ The long-obsolete 'gtime' function has been removed. ++ ++ Changes affecting build procedure ++ ++ 'zdump' no longer links in ialloc.o, as it's not needed. ++ ++ 'make check_time_t_alternatives' no longer assumes GNU diff. ++ ++ Changes affecting distribution tarballs ++ ++ The files checktab.awk and zoneinfo2tdf.pl are now distributed in ++ the tzdata tarball instead of the tzcode tarball, since they help ++ maintain the data. The NEWS and Theory files are now also ++ distributed in the tzdata tarball, as they're relevant for data. ++ (Thanks to Alan Barrett for pointing this out.) Also, the ++ leapseconds.awk file is no longer distributed in the tzcode ++ tarball, since it belongs in the tzdata tarball (where 2014f ++ inadvertently also distributed it). ++ ++ Changes affecting documentation and commentary ++ ++ A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for ++ suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms ++ for debugging it.) ++ ++ The man pages have been updated to use function prototypes, ++ to document thread-safe variants like localtime_r, and to document ++ the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and ++ mktime_z. ++ ++ The fields in Link lines have been renamed to be more descriptive ++ and more like the parameters of 'ln'. LINK-FROM has become TARGET, ++ and LINK-TO has become LINK-NAME. ++ ++ tz-link.htm mentions the IETF's tzdist working group; Windows ++ Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. ++ ++ Some broken URLs have been fixed in the commentary.

Two zones are added: Asia/Chita (split ++ from Asia/Yakutsk, and also with two hours subtracted) and ++ Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour ++ subtracted). (Thanks to Tim Parenti for much of the above.) ++ ++ Changes affecting time zone abbreviations ++ ++ Australian eastern time zone abbreviations are now AEST/AEDT not EST, ++ and similarly for the other Australian zones.

JWST now stands for Western Standard ++ Time, and JCST for Central Standard Time (formerly this was CJT). ++ These abbreviations are now used for time in Korea, Taiwan, ++ and Sakhalin while controlled by Japan. ++ ++ Changes affecting past time stamps ++ ++ China's five zones have been simplified to two, since the post-1970 ++ differences in the other three seem to have been imaginary. The ++ zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been ++ removed; backwards-compatibility links still work, albeit with ++ different behaviors for time stamps before May 1980. Asia/Urumqi's ++ 1980 transition to UT +08 has been removed, so that it is now at ++ +06 and not +08. (Thanks to Luther Ma and to Alois Treindl; ++ Treindl sent helpful translations of two papers by Guo Qingsheng.) ++ ++ Some zones have been turned into links, when they differed from existing ++ zones only for older UTC offsets where data entries were likely invented. ++ These changes affect UTC offsets in pre-1970 time stamps only. This is ++ similar to the change in release 2013e, except this time for western ++ Africa. The affected zones are: Africa/Bamako, Africa/Banjul, ++ Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, ++ Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and ++ Atlantic/St_Helena. This also affects the backwards-compatibility ++ link Africa/Timbuktu.

Its ++ transition to standard time has been changed from 1928 to 1901. ++ ++ Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, ++ then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. ++ In 1946 it observed DST from 05-15 through 09-30; in 1947 ++ from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. ++ (Thanks to Yu-Cheng Chuang.) ++ ++ Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. ++ ++ Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not ++ 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) ++ ++ Pacific/Pago_Pago has been changed from UT -11:30 to -11 for the ++ period from 1911 to 1950. ++ ++ Pacific/Chatham has been changed to New Zealand standard time plus ++ 45 minutes for the period before 1957, reflecting a 1956 remark in ++ the New Zealand parliament. ++ ++ Europe/Budapest has several pre-1946 corrections: in 1918 the transition ++ out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in ++ 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 ++ not 04-06 at 02:00; and there was no DST in 1920. ++ ++ Africa/Accra is now assumed to have observed DST from 1920 through 1935. ++ ++ Time in Russia before 1927 or so has been corrected by a few seconds in ++ the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, ++ Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and ++ Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 ++ point. (Thanks to Vladimir Karpinsky for the Moscow changes.) ++ ++ Changes affecting data format ++ ++ A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. ++ The new file's extended format allows multiple country codes per zone. ++ The older file is still installed but is deprecated; its format is ++ not changing and it will still be distributed for a while, but new ++ applications should use the new file. ++ ++ The new file format simplifies maintenance of obscure locations. ++ To test this, it adds coverage for the Crozet Islands and the ++ Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) ++ ++ The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. ++ It is still ASCII now, but commentary about the switch has been added. ++ The new file 'zone1970.tab' already uses UTF-8. ++ ++ Changes affecting code ++ ++ 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE ++ is defined. (Thanks to Elliott Hughes for reporting the problem.) ++ ++ 'zic' no longer mishandles input when ignoring case in locales that ++ are not compatible with English, e.g., unibyte Turkish locales when ++ compiled with HAVE_GETTEXT. ++ ++ Error diagnostics of 'zic' and 'yearistype' have been reworded so that ++ they no longer use ASCII '-' as if it were a dash. ++ ++ 'zic' now rejects output file names that contain '.' or '..' components. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ 'zic -v' now warns about output file names that do not follow ++ POSIX rules, or that contain a digit or '.'. (Thanks to Arthur ++ David Olson for starting the ball rolling on this.) ++ ++ Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. ++ ++ Changes affecting build procedure ++ ++ 'zic' no longer links in localtime.o and asctime.o, as they're not needed. ++ (Thanks to John Cochran.) ++ ++ Changes affecting documentation and commentary ++ ++ The 'Theory' file documents legacy names, the longstanding ++ exceptions to the POSIX-inspired file name rules. ++ ++ The 'zic' documentation clarifies the role of time types when ++ interpreting dates. (Thanks to Arthur David Olson.) ++ ++ Documentation and commentary now prefer UTF-8 to US-ASCII, ++ allowing the use of proper accents in foreign words and names. ++ Code and data have not changed because of this. (Thanks to ++ Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug ++ this.) ++ ++ Non-HTML documentation and commentary now use plain-text URLs instead of ++ HTML insertions, and are more consistent about bracketing URLs when they ++ are not already surrounded by white space. (Thanks to suggestions by ++ Steffen Nurpmeso.) ++ ++ There is new commentary about Xujiahui Observatory, the five time-zone ++ project in China from 1918 to 1949, timekeeping in Japanese-occupied ++ Shanghai, and Tibet Time in the 1950s.

(Thanks to Elliott Hughes.) ++ ++ Changes affecting the build procedure ++ ++ Avoid long strings in leapseconds.awk to work around a mawk bug. ++ (Thanks to Cyril Baurand.) ++ ++ Changes affecting documentation and commentary ++ ++ New file 'NEWS' that contains release notes like this one. ++ ++ Paraguay's law does not specify DST transition time; 00:00 is customary. ++ (Thanks to Waldemar Villamayor-Venialbo.) ++ ++ Minor capitalization fixes. ++ ++ Changes affecting version-control only ++ ++ The experimental GitHub repository now contains annotated and ++ signed tags for recent releases, e.g., '2013e' for Release 2013e. ++ Releases are tagged starting with 2012e; earlier releases were ++ done differently, and tags would either not have a simple name or ++ not exactly match what was released. ++ ++ 'make set-timestamps' is now simpler and a bit more portable. ++ ++ ++Release 2013e - 2013-09-19 23:50:04 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ This year Fiji will start DST on October 27, not October 20. ++ (Thanks to David Wheeler for the heads-up.) For now, guess that ++ Fiji will continue to spring forward the Sunday before the fourth ++ Monday in October. ++ ++ Changes affecting current and future time zone abbreviations ++ ++ Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian ++ time zone abbreviations since 1932. (Thanks to George Ziegler, ++ Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and ++ Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, ++ Asia/Makassar, and Asia/Pontianak. ++ ++ Use ART (UT -03, standard time), rather than WARST (also -03, but ++ daylight saving time) for San Luis, Argentina since 2009. ++ ++ Changes affecting Godthåb time stamps after 2037 if version mismatch ++ ++ Allow POSIX-like TZ strings where the transition time's hour can ++ range from -167 through 167, instead of the POSIX-required 0 ++ through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the ++ new Fiji rules. This is a more-compact way to represent ++ far-future time stamps for America/Godthab, America/Santiago, ++ Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, ++ Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by ++ this change. (Derived from a suggestion by Arthur David Olson.) ++ ++ Allow POSIX-like TZ strings where daylight saving time is in ++ effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western ++ Argentina Summer Time all year. This supports a more-compact way ++ to represent the 2013d data for America/Argentina/San_Luis. ++ Because of the change for San Luis noted above this change does not ++ affect the current data. (Thanks to Andrew Main (Zefram) for ++ suggestions that improved this change.) ++ ++ Where these two TZ changes take effect, there is a minor extension ++ to the tz file format in that it allows new values for the ++ embedded TZ-format string, and the tz file format version number ++ has therefore been increased from 2 to 3 as a precaution. ++ Version-2-based client code should continue to work as before for ++ all time stamps before 2038. Existing version-2-based client code ++ (tzcode, GNU/Linux, Solaris) has been tested on version-3-format ++ files, and typically works in practice even for time stamps after ++ 2037; the only known exception is America/Godthab. ++ ++ Changes affecting time stamps before 1970 ++ ++ Pacific/Johnston is now a link to Pacific/Honolulu. This corrects ++ some errors before 1947. ++ ++ Some zones have been turned into links, when they differ from existing ++ zones only in older data entries that were likely invented or that ++ differ only in LMT or transitions from LMT. These changes affect ++ only time stamps before 1943. The affected zones are: ++ Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, ++ America/Grenada, America/Guadeloupe, America/Marigot, ++ America/Montserrat, America/St_Barthelemy, America/St_Kitts, ++ America/St_Lucia, America/St_Thomas, America/St_Vincent, ++ America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for ++ confirming that the old Europe/Vaduz zone was wrong and the new ++ link is better for WWII-era times.) ++ ++ Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects ++ America/Cayman, America/Jamaica and America/Grand_Turk time stamps ++ from 1890 to 1912. ++ ++ Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. ++ This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks ++ to Alois Treindl). ++ ++ Change the date of the circa-1850 Zurich transition from 1849-09-12 ++ to 1853-07-16, overriding Shanks with data from Messerli about ++ postal and telegraph time in Switzerland. ++ ++ Changes affecting time zone abbreviations before 1970 ++ ++ For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, ++ as Jakarta was called Batavia back then. ++ ++ Changes affecting API ++ ++ The 'zic' command now outputs a dummy transition when far-future ++ data can't be summarized using a TZ string, and uses a 402-year ++ window rather than a 400-year window. For the current data, this ++ affects only the Asia/Tehran file. It does not affect any of the ++ time stamps that this file represents, so zdump outputs the same ++ information as before. (Thanks to Andrew Main (Zefram).) ++ ++ The 'date' command has a new '-r' option, which lets you specify ++ the integer time to display, a la FreeBSD. ++ ++ The 'tzselect' command has two new options '-c' and '-n', which lets you ++ select a zone based on latitude and longitude. ++ ++ The 'zic' command's '-v' option now warns about constructs that ++ require the new version-3 binary file format. (Thanks to Arthur ++ David Olson for the suggestion.) ++ ++ Support for floating-point time_t has been removed. ++ It was always dicey, and POSIX no longer requires it. ++ (Thanks to Eric Blake for suggesting to the POSIX committee to ++ remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy ++ Heninger, Arthur David Olson, and Alois Treindl, for reporting ++ bugs and elucidating some of the corners of the old floating-point ++ implementation.) ++ ++ The signatures of 'offtime', 'timeoff', and 'gtime' have been ++ changed back to the old practice of using 'long' to represent UT ++ offsets. This had been inadvertently and mistakenly changed to ++ 'int_fast32_t'. (Thanks to Christos Zoulas.) ++ ++ The code avoids undefined behavior on integer overflow in some ++ more places, including gmtime, localtime, mktime and zdump. ++ ++ Changes affecting the zdump utility ++ ++ zdump now outputs "UT" when referring to Universal Time, not "UTC". ++ "UTC" does not make sense for time stamps that predate the introduction ++ of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen ++ for clarifying UT vs UTC.) ++ ++ Data changes affecting behavior of tzselect and similar programs ++ ++ Country code BQ is now called the more-common name "Caribbean Netherlands" ++ rather than the more-official "Bonaire, St Eustatius & Saba". ++ ++ Remove from zone.tab the names America/Montreal, America/Shiprock, ++ and Antarctica/South_Pole, as they are equivalent to existing ++ same-country-code zones for post-1970 time stamps. The data entries for ++ these names are unchanged, so the names continue to work as before. ++ ++ Changes affecting code internals ++ ++ zic -c now runs way faster on 64-bit hosts when given large numbers. ++ ++ zic now uses vfprintf to avoid allocating and freeing some memory. ++ ++ tzselect now computes the list of continents from the data, ++ rather than have it hard-coded. ++ ++ Minor changes pacify GCC 4.7.3 and GCC 4.8.1. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is now generated automatically from a ++ new file 'leap-seconds.list', which is a copy of ++ <ftp://time.nist.gov/pub/leap-seconds.list>. ++ A new source file 'leapseconds.awk' implements this. ++ The goal is simplification of the future maintenance of 'leapseconds'. ++ ++ When building the 'posix' or 'right' subdirectories, if the ++ subdirectory would be a copy of the default subdirectory, it is ++ now made a symbolic link if that is supported. This saves about ++ 2 MB of file system space. ++ ++ The links America/Shiprock and Antarctica/South_Pole have been ++ moved to the 'backward' file. This affects only nondefault builds ++ that omit 'backward'. ++ ++ Changes affecting version-control only ++ ++ .gitignore now ignores 'date'. ++ ++ Changes affecting documentation and commentary ++ ++ Changes to the 'tzfile' man page ++ ++ It now mentions that the binary file format may be extended in ++ future versions by appending data. ++ ++ It now refers to the 'zdump' and 'zic' man pages. ++ ++ Changes to the 'zic' man page ++ ++ It lists conditions that elicit a warning with '-v'. ++ ++ It says that the behavior is unspecified when duplicate names ++ are given, or if the source of one link is the target of another. ++ ++ Its examples are updated to match the latest data. ++ ++ The definition of white space has been clarified slightly. ++ (Thanks to Michael Deckers.) ++ ++ Changes to the 'Theory' file ++ ++ There is a new section about the accuracy of the tz database, ++ describing the many ways that errors can creep in, and ++ explaining why so many of the pre-1970 time stamps are wrong or ++ misleading (thanks to Steve Allen, Lester Caine, and Garrett ++ Wollman for discussions that contributed to this). ++ ++ The 'Theory' file describes LMT better (this follows a ++ suggestion by Guy Harris). ++ ++ It refers to the 2013 edition of POSIX rather than the 2004 edition. ++ ++ It's mentioned that excluding 'backward' should not affect the ++ other data, and it suggests at least one zone.tab name per ++ inhabited country (thanks to Stephen Colebourne). ++ ++ Some longstanding restrictions on names are documented, e.g., ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ ++ It gives more reasons for the 1970 cutoff. ++ ++ It now mentions which time_t variants are supported, such as ++ signed integer time_t. (Thanks to Paul Goyette for reporting ++ typos in an experimental version of this change.) ++ ++ (Thanks to Philip Newton for correcting typos in these changes.) ++ ++ Documentation and commentary is more careful to distinguish UT in ++ general from UTC in particular.

Since Mar 11 (the old start ++ date, as listed in 2012a) is just a little over a week away, this ++ change is urgent. ++ ++ Less importantly, an excess tab in one of the changes in zone.tab ++ in 2012a has been removed. ++ ++ ++Release 2012a - 2012-03-01 18:28:10 +0700 ++ ++ The changes in tzcode2012a (compared to the previous version, 2011i) ++ are entirely to the README and tz-art.htm and tz-link.htm files, if ++ none of those concern you, you can ignore the code update.

Second, the Pridnestrovian Moldavian Republic ++ (Europe/Tiraspol) decided not to split from the rest of Moldova after ++ all, and consequently that zone has been removed (again) and reinstated ++ in the "backward" file as a link to Europe/Chisinau. And third, the ++ end date for Fiji's summer time this summer was moved forward from the ++ earlier planned Feb 26, to Jan 22. ++ ++ Apart from that, Moldova (MD) returns to a single entry in zone.tab ++ (and the incorrect syntax that was in the 2011m version of that file ++ is so fixed - it would have been fixed in a different way had this ++ change not happened - that's the "missing" sccs version id). ++ ++ ++Release data2011m - 2011-10-24 21:42:16 +0700 ++ ++ In particular, the typos in comments in the data (2011-11-17 should have ++ been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that ++ Tim Parenti noted) have been fixed, and the change for Ukraine has been ++ made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to ++ Tim Parenti, and also Denys Gavrysh) ++ ++ In addition, I added Europe/Tiraspol to zone.tab. ++ ++ This time, all the files have new version numbers...

However, some releases (e.g., ++code2010a, data2012c) consist of just one or the other tarball, and a ++few (e.g., code2012c-data2012d) have tarballs with mixed version ++numbers. Recent releases also come in an experimental format ++consisting of a single tarball tzdb-R.tar.lz with extra data. ++ ++Release time stamps are taken from the release's commit (for newer, ++Git-based releases), from the newest file in the tarball (for older ++releases, where this info is available) or from the email announcing ++the release (if all else fails; these are marked with a time zone of ++-0000 and an "is missing!" comment). ++ ++Earlier versions of the code and data were not announced on the tz ++list and are not summarized here. ++ ++This file is in the public domain. ++ ++Local Variables: ++coding: utf-8 ++End: +Index: contrib/tzdata/README +=================================================================== +--- contrib/tzdata/README (nonexistent) ++++ contrib/tzdata/README (working copy) +@@ -0,0 +1,71 @@ ++README for the tz distribution ++ ++"What time is it?" -- Richard Deacon as The King ++"Any time you want it to be." -- Frank Baxter as The Scientist ++ (from the Bell System film "About Time") ++ ++The Time Zone Database (often called tz or zoneinfo) contains code and ++data that represent the history of local time for many representative ++locations around the globe.

To represent this ++data, the world is partitioned into regions whose clocks all agree ++about time stamps that occur after the somewhat-arbitrary cutoff point ++of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region, ++the database records all known clock transitions, and labels the region ++with a notable location. Although 1970 is a somewhat-arbitrary ++cutoff, there are significant challenges to moving the cutoff earlier ++even by a decade or two, due to the wide variety of local practices ++before computer timekeeping became prevalent. ++ ++Clock transitions before 1970 are recorded for each such location, ++because most systems support time stamps before 1970 and could ++misbehave if data entries were omitted for pre-1970 transitions. ++However, the database is not designed for and does not suffice for ++applications requiring accurate handling of all past times everywhere, ++as it would take far too much effort and guesswork to record all ++details of pre-1970 civil timekeeping. ++ ++As described below, reference source code for using the tz database is ++also available. The tz code is upwards compatible with POSIX, an ++international standard for UNIX-like systems. As of this writing, the ++current edition of POSIX is: ++ ++ The Open Group Base Specifications Issue 7 ++ IEEE Std 1003.1, 2013 Edition ++ <http://pubs.opengroup.org/onlinepubs/9699919799/> ++ ++ ++ ++----- Names of time zone rules ----- ++ ++Each of the database's time zone rules has a unique name. ++Inexperienced users are not expected to select these names unaided. ++Distributors should provide documentation and/or a simple selection ++interface that explains the names; for one example, see the 'tzselect' ++program in the tz code. The Unicode Common Locale Data Repository ++<http://cldr.unicode.org/> contains data that may be useful for other ++selection interfaces. ++ ++The time zone rule naming conventions attempt to strike a balance ++among the following goals: ++ ++ * Uniquely identify every region where clocks have agreed since 1970. ++ This is essential for the intended use: static clocks keeping local ++ civil time. ++ ++ * Indicate to experts where that region is. ++ ++ * Be robust in the presence of political changes. For example, names ++ of countries are ordinarily not used, to avoid incompatibilities ++ when countries change their name (e.g. Zaire->Congo) or when ++ locations change countries (e.g. Hong Kong from UK colony to ++ China). ++ ++ * Be portable to a wide variety of implementations. ++ ++ * Use a consistent naming conventions over the entire world. ++ ++Names normally have the form AREA/LOCATION, where AREA is the name ++of a continent or ocean, and LOCATION is the name of a specific ++location within that region. North and South America share the same ++area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York', ++and 'Pacific/Honolulu'. ++ ++Here are the general rules used for choosing location names, ++in decreasing order of importance: ++ ++ Use only valid POSIX file name components (i.e., the parts of ++ names other than '/'). Do not use the file name ++ components '.' and '..'. Within a file name component, ++ use only ASCII letters, '.', '-' and '_'. Do not use ++ digits, as that might create an ambiguity with POSIX ++ TZ strings. A file name component must not exceed 14 ++ characters or start with '-'. E.g., prefer 'Brunei' ++ to 'Bandar_Seri_Begawan'. Exceptions: see the discussion ++ of legacy names below. ++ A name must not be empty, or contain '//', or start or end with '/'. ++ Do not use names that differ only in case. Although the reference ++ implementation is case-sensitive, some other implementations ++ are not, and they would mishandle names differing only in case. ++ If one name A is an initial prefix of another name AB (ignoring case), ++ then B must not start with '/', as a regular file cannot have ++ the same name as a directory in POSIX. For example, ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ Uninhabited regions like the North Pole and Bouvet Island ++ do not need locations, since local time is not defined there. ++ There should typically be at least one name for each ISO 3166-1 ++ officially assigned two-letter code for an inhabited country ++ or territory. ++ If all the clocks in a region have agreed since 1970, ++ don't bother to include more than one location ++ even if subregions' clocks disagreed before 1970. ++ Otherwise these tables would become annoyingly large. ++ If a name is ambiguous, use a less ambiguous alternative; ++ e.g. many cities are named San José and Georgetown, so ++ prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'. ++ Keep locations compact. Use cities or small islands, not countries ++ or regions, so that any future time zone changes do not split ++ locations into different time zones. E.g. prefer 'Paris' ++ to 'France', since France has had multiple time zones. ++ Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and ++ prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'. ++ The POSIX file name restrictions encourage this rule. ++ Use the most populous among locations in a zone, ++ e.g. prefer 'Shanghai' to 'Beijing'. Among locations with ++ similar populations, pick the best-known location, ++ e.g. prefer 'Rome' to 'Milan'. ++ Use the singular form, e.g. prefer 'Canary' to 'Canaries'. ++ Omit common suffixes like '_Islands' and '_City', unless that ++ would lead to ambiguity. E.g. prefer 'Cayman' to ++ 'Cayman_Islands' and 'Guatemala' to 'Guatemala_City', ++ but prefer 'Mexico_City' to 'Mexico' because the country ++ of Mexico has several time zones. ++ Use '_' to represent a space. ++ Omit '.' from abbreviations in names, e.g. prefer 'St_Helena' ++ to 'St._Helena'. ++ Do not change established names if they only marginally ++ violate the above rules. For example, don't change ++ the existing name 'Rome' to 'Milan' merely because ++ Milan's population has grown to be somewhat greater ++ than Rome's. ++ If a name is changed, put its old spelling in the 'backward' file. ++ This means old spellings will continue to work. ++ ++The file 'zone1970.tab' lists geographical locations used to name time ++zone rules. It is intended to be an exhaustive list of names for ++geographic regions as described above; this is a subset of the names ++in the data. Although a 'zone1970.tab' location's longitude ++corresponds to its LMT offset with one hour for every 15 degrees east ++longitude, this relationship is not exact. ++ ++Older versions of this package used a different naming scheme, ++and these older names are still supported. ++See the file 'backward' for most of these older names ++(e.g., 'US/Eastern' instead of 'America/New_York'). ++The other old-fashioned names still supported are ++'WET', 'CET', 'MET', and 'EET' (see the file 'europe'). ++ ++Older versions of this package defined legacy names that are ++incompatible with the first rule of location names, but which are ++still supported. These legacy names are mostly defined in the file ++'etcetera'. Also, the file 'backward' defines the legacy names ++'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file ++'northamerica' defines the legacy names 'EST5EDT', 'CST6CDT', ++'MST7MDT', and 'PST8PDT'. ++ ++Excluding 'backward' should not affect the other data. If ++'backward' is excluded, excluding 'etcetera' should not affect the ++remaining data. ++ ++ ++----- Time zone abbreviations ----- ++ ++When this package is installed, it generates time zone abbreviations ++like 'EST' to be compatible with human tradition and POSIX. ++Here are the general rules used for choosing time zone abbreviations, ++in decreasing order of importance: ++ ++ Use three or more characters that are ASCII alphanumerics or '+' or '-'. ++ Previous editions of this database also used characters like ++ ' ' and '?', but these characters have a special meaning to ++ the shell and cause commands like ++ set `date` ++ to have unexpected effects. ++ Previous editions of this rule required upper-case letters, ++ but the Congressman who introduced Chamorro Standard Time ++ preferred "ChST", so lower-case letters are now allowed. ++ Also, POSIX from 2001 on relaxed the rule to allow '-', '+', ++ and alphanumeric characters from the portable character set ++ in the current locale. In practice ASCII alphanumerics and ++ '+' and '-' are safe in all locales. ++ ++ In other words, in the C locale the POSIX extended regular ++ expression [-+[:alnum:]]{3,} should match the abbreviation. ++ This guarantees that all abbreviations could have been ++ specified by a POSIX TZ string. ++ ++ Use abbreviations that are in common use among English-speakers, ++ e.g. 'EST' for Eastern Standard Time in North America. ++ We assume that applications translate them to other languages ++ as part of the normal localization process; for example, ++ a French application might translate 'EST' to 'HNE'. ++ ++ For zones whose times are taken from a city's longitude, use the ++ traditional xMT notation, e.g. 'PMT' for Paris Mean Time. ++ The only name like this in current use is 'GMT'. ++ ++ Use 'LMT' for local mean time of locations before the introduction ++ of standard time; see "Scope of the tz database". ++ ++ If there is no common English abbreviation, use numeric offsets like ++ -05 and +0830 that are generated by zic's %z notation. ++ ++ [The remaining guidelines predate the introduction of %z. ++ They are problematic as they mean tz data entries invent ++ notation rather than record it. These guidelines are now ++ deprecated and the plan is to gradually move to %z for ++ inhabited locations and to "-00" for uninhabited locations.] ++ ++ If there is no common English abbreviation, abbreviate the English ++ translation of the usual phrase used by native speakers. ++ If this is not available or is a phrase mentioning the country ++ (e.g. "Cape Verde Time"), then: ++ ++ When a country is identified with a single or principal zone, ++ append 'T' to the country's ISO code, e.g. 'CVT' for ++ Cape Verde Time. For summer time append 'ST'; ++ for double summer time append 'DST'; etc. ++ Otherwise, take the first three letters of an English place ++ name identifying each zone and append 'T', 'ST', etc. ++ as before; e.g. 'VLAST' for VLAdivostok Summer Time. ++ ++ Use UT (with time zone abbreviation '-00') for locations while ++ uninhabited. The leading '-' is a flag that the time ++ zone is in some sense undefined; this notation is ++ derived from Internet RFC 3339. ++ ++Application writers should note that these abbreviations are ambiguous ++in practice: e.g. 'CST' has a different meaning in China than ++it does in the United States. In new applications, it's often better ++to use numeric UT offsets like '-0600' instead of time zone ++abbreviations like 'CST'; this avoids the ambiguity. ++ ++ ++----- Accuracy of the tz database ----- ++ ++The tz database is not authoritative, and it surely has errors. ++Corrections are welcome and encouraged; see the file CONTRIBUTING. ++Users requiring authoritative data should consult national standards ++bodies and the references cited in the database's comments. ++ ++Errors in the tz database arise from many sources: ++ ++ * The tz database predicts future time stamps, and current predictions ++ will be incorrect after future governments change the rules. ++ For example, if today someone schedules a meeting for 13:00 next ++ October 1, Casablanca time, and tomorrow Morocco changes its ++ daylight saving rules, software can mess up after the rule change ++ if it blithely relies on conversions made before the change. ++ ++ * The pre-1970 entries in this database cover only a tiny sliver of how ++ clocks actually behaved; the vast majority of the necessary ++ information was lost or never recorded. Thousands more zones would ++ be needed if the tz database's scope were extended to cover even ++ just the known or guessed history of standard time; for example, ++ the current single entry for France would need to split into dozens ++ of entries, perhaps hundreds. And in most of the world even this ++ approach would be misleading due to widespread disagreement or ++ indifference about what times should be observed. In her 2015 book ++ "The Global Transformation of Time, 1870-1950", Vanessa Ogle writes ++ "Outside of Europe and North America there was no system of time ++ zones at all, often not even a stable landscape of mean times, ++ prior to the middle decades of the twentieth century". See: ++ Timothy Shenk, Booked: A Global History of Time. Dissent 2015-12-17 ++ https://www.dissentmagazine.org/blog/booked-a-global-history-of-time-vanessa-ogle ++ ++ * Most of the pre-1970 data entries come from unreliable sources, often ++ astrology books that lack citations and whose compilers evidently ++ invented entries when the true facts were unknown, without ++ reporting which entries were known and which were invented. ++ These books often contradict each other or give implausible entries, ++ and on the rare occasions when they are checked they are ++ typically found to be incorrect. ++ ++ * For the UK the tz database relies on years of first-class work done by ++ Joseph Myers and others; see <http://www.polyomino.org.uk/british-time/>. ++ Other countries are not done nearly as well. ++ ++ * Sometimes, different people in the same city would maintain clocks ++ that differed significantly. Railway time was used by railroad ++ companies (which did not always agree with each other), ++ church-clock time was used for birth certificates, etc. ++ Often this was merely common practice, but sometimes it was set by law. ++ For example, from 1891 to 1911 the UT offset in France was legally ++ 0:09:21 outside train stations and 0:04:21 inside. ++ ++ * Although a named location in the tz database stands for the ++ containing region, its pre-1970 data entries are often accurate for ++ only a small subset of that region. For example, Europe/London ++ stands for the United Kingdom, but its pre-1847 times are valid ++ only for locations that have London's exact meridian, and its 1847 ++ transition to GMT is known to be valid only for the L&NW and the ++ Caledonian railways. ++ ++ * The tz database does not record the earliest time for which a zone's ++ data entries are thereafter valid for every location in the region. ++ For example, Europe/London is valid for all locations in its ++ region after GMT was made the standard time, but the date of ++ standardization (1880-08-02) is not in the tz database, other than ++ in commentary. For many zones the earliest time of validity is ++ unknown. ++ ++ * The tz database does not record a region's boundaries, and in many ++ cases the boundaries are not known. For example, the zone ++ America/Kentucky/Louisville represents a region around the city of ++ Louisville, the boundaries of which are unclear. ++ ++ * Changes that are modeled as instantaneous transitions in the tz ++ database were often spread out over hours, days, or even decades. ++ ++ * Even if the time is specified by law, locations sometimes ++ deliberately flout the law. ++ ++ * Early timekeeping practices, even assuming perfect clocks, were ++ often not specified to the accuracy that the tz database requires. ++ ++ * Sometimes historical timekeeping was specified more precisely ++ than what the tz database can handle. For example, from 1909 to ++ 1937 Netherlands clocks were legally UT +00:19:32.13, but the tz ++ database cannot represent the fractional second. ++ ++ * Even when all the timestamp transitions recorded by the tz database ++ are correct, the tz rules that generate them may not faithfully ++ reflect the historical rules. For example, from 1922 until World ++ War II the UK moved clocks forward the day following the third ++ Saturday in April unless that was Easter, in which case it moved ++ clocks forward the previous Sunday. Because the tz database has no ++ way to specify Easter, these exceptional years are entered as ++ separate tz Rule lines, even though the legal rules did not change. ++ ++ * The tz database models pre-standard time using the proleptic Gregorian ++ calendar and local mean time (LMT), but many people used other ++ calendars and other timescales. For example, the Roman Empire used ++ the Julian calendar, and had 12 varying-length daytime hours with a ++ non-hour-based system at night. ++ ++ * Early clocks were less reliable, and data entries do not represent ++ this unreliability. ++ ++ * As for leap seconds, civil time was not based on atomic time before ++ 1972, and we don't know the history of earth's rotation accurately ++ enough to map SI seconds to historical solar time to more than ++ about one-hour accuracy. See: Morrison LV, Stephenson FR. ++ Historical values of the Earth's clock error Delta T and the ++ calculation of eclipses. J Hist Astron. 2004;35:327-36 ++ <http://adsabs.harvard.edu/full/2004JHA....35..327M>; ++ Historical values of the Earth's clock error. J Hist Astron. 2005;36:339 ++ <http://adsabs.harvard.edu/full/2005JHA....36..339M>. ++ ++ * The relationship between POSIX time (that is, UTC but ignoring leap ++ seconds) and UTC is not agreed upon after 1972. Although the POSIX ++ clock officially stops during an inserted leap second, at least one ++ proposed standard has it jumping back a second instead; and in ++ practice POSIX clocks more typically either progress glacially during ++ a leap second, or are slightly slowed while near a leap second. ++ ++ * The tz database does not represent how uncertain its information is. ++ Ideally it would contain information about when data entries are ++ incomplete or dicey. Partial temporal knowledge is a field of ++ active research, though, and it's not clear how to apply it here. ++ ++In short, many, perhaps most, of the tz database's pre-1970 and future ++time stamps are either wrong or misleading. Any attempt to pass the ++tz database off as the definition of time should be unacceptable to ++anybody who cares about the facts. In particular, the tz database's ++LMT offsets should not be considered meaningful, and should not prompt ++creation of zones merely because two locations differ in LMT or ++transitioned to standard time at different dates. ++ ++ ++----- Time and date functions ----- ++ ++The tz code contains time and date functions that are upwards ++compatible with those of POSIX. ++ ++POSIX has the following properties and limitations. ++ ++* In POSIX, time display in a process is controlled by the ++ environment variable TZ. Unfortunately, the POSIX TZ string takes ++ a form that is hard to describe and is error-prone in practice. ++ Also, POSIX TZ strings can't deal with other (for example, Israeli) ++ daylight saving time rules, or situations where more than two ++ time zone abbreviations are used in an area. ++ ++ The POSIX TZ string takes the following form: ++ ++ stdoffset[dst[offset][,date[/time],date[/time]]] ++ ++ where: ++ ++ std and dst ++ are 3 or more characters specifying the standard ++ and daylight saving time (DST) zone names. ++ Starting with POSIX.1-2001, std and dst may also be ++ in a quoted form like "<UTC+10>"; this allows ++ "+" and "-" in the names. ++ offset ++ is of the form '[+-]hh:[mm[:ss]]' and specifies the ++ offset west of UT. 'hh' may be a single digit; 0<=hh<=24. ++ The default DST offset is one hour ahead of standard time. ++ date[/time],date[/time] ++ specifies the beginning and end of DST. If this is absent, ++ the system supplies its own rules for DST, and these can ++ differ from year to year; typically US DST rules are used. ++ time ++ takes the form 'hh:[mm[:ss]]' and defaults to 02:00. ++ This is the same format as the offset, except that a ++ leading '+' or '-' is not allowed. ++ date ++ takes one of the following forms: ++ Jn (1<=n<=365) ++ origin-1 day number not counting February 29 ++ n (0<=n<=365) ++ origin-0 day number counting February 29 if present ++ Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) ++ for the dth day of week n of month m of the year, ++ where week 1 is the first week in which day d appears, ++ and '5' stands for the last week in which day d appears ++ (which may be either the 4th or 5th week). ++ Typically, this is the only useful form; ++ the n and Jn forms are rarely used. ++ ++ Here is an example POSIX TZ string, for US Pacific time using rules ++ appropriate from 1987 through 2006: ++ ++ TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00' ++ ++ This POSIX TZ string is hard to remember, and mishandles time stamps ++ before 1987 and after 2006. With this package you can use this ++ instead: ++ ++ TZ='America/Los_Angeles' ++ ++* POSIX does not define the exact meaning of TZ values like "EST5EDT". ++ Typically the current US DST rules are used to interpret such values, ++ but this means that the US DST rules are compiled into each program ++ that does time conversion. This means that when US time conversion ++ rules change (as in the United States in 1987), all programs that ++ do time conversion must be recompiled to ensure proper results. ++ ++* The TZ environment variable is process-global, which makes it hard ++ to write efficient, thread-safe applications that need access ++ to multiple time zones. ++ ++* In POSIX, there's no tamper-proof way for a process to learn the ++ system's best idea of local wall clock. (This is important for ++ applications that an administrator wants used only at certain times - ++ without regard to whether the user has fiddled the "TZ" environment ++ variable. While an administrator can "do everything in UTC" to get ++ around the problem, doing so is inconvenient and precludes handling ++ daylight saving time shifts - as might be required to limit phone ++ calls to off-peak hours.) ++ ++* POSIX provides no convenient and efficient way to determine the UT ++ offset and time zone abbreviation of arbitrary time stamps, ++ particularly for time zone settings that do not fit into the ++ POSIX model. ++ ++* POSIX requires that systems ignore leap seconds. ++ ++* The tz code attempts to support all the time_t implementations ++ allowed by POSIX. The time_t type represents a nonnegative count of ++ seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds. ++ In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit ++ signed time_t values stop working after 2038-01-19 03:14:07 UTC, so ++ new implementations these days typically use a signed 64-bit integer. ++ Unsigned 32-bit integers are used on one or two platforms, ++ and 36-bit and 40-bit integers are also used occasionally. ++ Although earlier POSIX versions allowed time_t to be a ++ floating-point type, this was not supported by any practical ++ systems, and POSIX.1-2013 and the tz code both require time_t ++ to be an integer type. ++ ++These are the extensions that have been made to the POSIX functions: ++ ++* The "TZ" environment variable is used in generating the name of a file ++ from which time zone information is read (or is interpreted a la ++ POSIX); "TZ" is no longer constrained to be a three-letter time zone ++ name followed by a number of hours and an optional three-letter ++ daylight time zone name. The daylight saving time rules to be used ++ for a particular time zone are encoded in the time zone file; ++ the format of the file allows U.S., Australian, and other rules to be ++ encoded, and allows for situations where more than two time zone ++ abbreviations are used. ++ ++ It was recognized that allowing the "TZ" environment variable to ++ take on values such as "America/New_York" might cause "old" programs ++ (that expect "TZ" to have a certain form) to operate incorrectly; ++ consideration was given to using some other environment variable ++ (for example, "TIMEZONE") to hold the string used to generate the ++ time zone information file name. In the end, however, it was decided ++ to continue using "TZ": it is widely used for time zone purposes; ++ separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; ++ and systems where "new" forms of "TZ" might cause problems can simply ++ use TZ values such as "EST5EDT" which can be used both by ++ "new" programs (a la POSIX) and "old" programs (as zone names and ++ offsets). ++ ++* The code supports platforms with a UT offset member in struct tm, ++ e.g., tm_gmtoff. ++ ++* The code supports platforms with a time zone abbreviation member in ++ struct tm, e.g., tm_zone. ++ ++* Since the "TZ" environment variable can now be used to control time ++ conversion, the "daylight" and "timezone" variables are no longer ++ needed. (These variables are defined and set by "tzset"; however, their ++ values will not be used by "localtime.") ++ ++* Functions tzalloc, tzfree, localtime_rz, and mktime_z for ++ more-efficient thread-safe applications that need to use ++ multiple time zones. The tzalloc and tzfree functions ++ allocate and free objects of type timezone_t, and localtime_rz ++ and mktime_z are like localtime_r and mktime with an extra ++ timezone_t argument. The functions were inspired by NetBSD. ++ ++* A function "tzsetwall" has been added to arrange for the system's ++ best approximation to local wall clock time to be delivered by ++ subsequent calls to "localtime." Source code for portable ++ applications that "must" run on local wall clock time should call ++ "tzsetwall();" if such code is moved to "old" systems that don't ++ provide tzsetwall, you won't be able to generate an executable program. ++ (These time zone functions also arrange for local wall clock time to be ++ used if tzset is called - directly or indirectly - and there's no "TZ" ++ environment variable; portable applications should not, however, rely ++ on this behavior since it's not the way SVR2 systems behave.) ++ ++* Negative time_t values are supported, on systems where time_t is signed. ++ ++* These functions can account for leap seconds, thanks to Bradley White. ++ ++Points of interest to folks with other systems: ++ ++* Code compatible with this package is already part of many platforms, ++ including GNU/Linux, Android, the BSDs, Chromium OS, Cygwin, AIX, iOS, ++ BlackBery 10, macOS, Microsoft Windows, OpenVMS, and Solaris. ++ On such hosts, the primary use of this package ++ is to update obsolete time zone rule tables. ++ To do this, you may need to compile the time zone compiler ++ 'zic' supplied with this package instead of using the system 'zic', ++ since the format of zic's input is occasionally extended, ++ and a platform may still be shipping an older zic. ++ ++* The UNIX Version 7 "timezone" function is not present in this package; ++ it's impossible to reliably map timezone's arguments (a "minutes west ++ of GMT" value and a "daylight saving time in effect" flag) to a ++ time zone abbreviation, and we refuse to guess. ++ Programs that in the past used the timezone function may now examine ++ tzname[localtime(&clock)->tm_isdst] to learn the correct time ++ zone abbreviation to use. Alternatively, use ++ localtime(&clock)->tm_zone if this has been enabled. ++ ++* The 4.2BSD gettimeofday function is not used in this package. ++ This formerly let users obtain the current UTC offset and DST flag, ++ but this functionality was removed in later versions of BSD. ++ ++* In SVR2, time conversion fails for near-minimum or near-maximum ++ time_t values when doing conversions for places that don't use UT. ++ This package takes care to do these conversions correctly. ++ A comment in the source code tells how to get compatibly wrong ++ results. ++ ++The functions that are conditionally compiled if STD_INSPIRED is defined ++should, at this point, be looked on primarily as food for thought. They are ++not in any sense "standard compatible" - some are not, in fact, specified in ++*any* standard. They do, however, represent responses of various authors to ++standardization proposals. ++ ++Other time conversion proposals, in particular the one developed by folks at ++Hewlett Packard, offer a wider selection of functions that provide capabilities ++beyond those provided here. The absence of such functions from this package ++is not meant to discourage the development, standardization, or use of such ++functions. Rather, their absence reflects the decision to make this package ++contain valid extensions to POSIX, to ensure its broad acceptability. If ++more powerful time conversion functions can be standardized, so much the ++better. ++ ++ ++----- Interface stability ----- ++ ++The tz code and data supply the following interfaces: ++ ++ * A set of zone names as per "Names of time zone rules" above. ++ ++ * Library functions described in "Time and date functions" above. ++ ++ * The programs tzselect, zdump, and zic, documented in their man pages. ++ ++ * The format of zic input files, documented in the zic man page. ++ ++ * The format of zic output files, documented in the tzfile man page. ++ ++ * The format of zone table files, documented in zone1970.tab. ++ ++ * The format of the country code file, documented in iso3166.tab. ++ ++When these interfaces are changed, an effort is made to preserve ++backward compatibility. For example, tz data files typically do not ++rely on recently-added zic features, so that users can run older zic ++versions to process newer data files. ++ ++Interfaces not listed above are less stable. For example, users ++should not rely on particular UT offsets or abbreviations for time ++stamps, as data entries are often based on guesswork and these guesses ++may be corrected or improved. ++ ++ ++----- Calendrical issues ----- ++ ++Calendrical issues are a bit out of scope for a time zone database, ++but they indicate the sort of problems that we would run into if we ++extended the time zone database further into the past. An excellent ++resource in this area is Nachum Dershowitz and Edward M. Reingold, ++Calendrical Calculations: Third Edition, Cambridge University Press (2008) ++<http://emr.cs.iit.edu/home/reingold/calendar-book/third-edition/>. ++Other information and sources are given below.

Jet Propulsion Laboratory ++(JPL) coordinators have kept Mars time on and off at least since 1997 ++for the Mars Pathfinder mission. Some of their family members have ++also adapted to Mars time. Dozens of special Mars watches were built ++for JPL workers who kept Mars time during the Mars Exploration ++Rovers mission (2004). These timepieces look like normal Seikos and ++Citizens but use Mars seconds rather than terrestrial seconds. ++ ++A Mars solar day is called a "sol" and has a mean period equal to ++about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is ++divided into a conventional 24-hour clock, so each Mars second equals ++about 1.02749125 terrestrial seconds. ++ ++The prime meridian of Mars goes through the center of the crater ++Airy-0, named in honor of the British astronomer who built the ++Greenwich telescope that defines Earth's prime meridian. Mean solar ++time on the Mars prime meridian is called Mars Coordinated Time (MTC). ++ ++Each landed mission on Mars has adopted a different reference for ++solar time keeping, so there is no real standard for Mars time zones. ++For example, the Mars Exploration Rover project (2004) defined two ++time zones "Local Solar Time A" and "Local Solar Time B" for its two ++missions, each zone designed so that its time equals local true solar ++time at approximately the middle of the nominal mission. Such a "time ++zone" is not particularly suited for any application other than the ++mission itself. ++ ++Many calendars have been proposed for Mars, but none have achieved ++wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a ++sequential count of Mars solar days elapsed since about 1873-12-29 ++12:00 GMT. ++ ++The tz database does not currently support Mars time, but it is ++documented here in the hopes that support will be added eventually. ++ ++Sources: ++ ++Michael Allison and Robert Schmunk, ++"Technical Notes on Mars Solar Time as Adopted by the Mars24 Sunclock" ++<http://www.giss.nasa.gov/tools/mars24/help/notes.html> (2012-08-08). ++ ++Jia-Rui Chong, "Workdays Fit for a Martian", Los Angeles Times ++<http://articles.latimes.com/2004/jan/14/science/sci-marstime14> ++(2004-01-14), pp A1, A20-A21. ++ ++Tom Chmielewski, "Jet Lag Is Worse on Mars", The Atlantic (2015-02-26) ++<http://www.theatlantic.com/technology/archive/2015/02/jet-lag-is-worse-on-mars/386033/> ++ ++----- ++ ++This file is in the public domain, so clarified as of 2009-05-17 by ++Arthur David Olson. ++ ++----- ++Local Variables: ++coding: utf-8 ++End: +Index: contrib/tzdata/africa +=================================================================== +--- contrib/tzdata/africa (revision 309576) ++++ contrib/tzdata/africa (working copy) +@@ -343,6 +343,12 @@ Rule Egypt 2007 only - Sep Thu>=1 24:00 0 - + # decision to abandon DST permanently.

This fixes a bug with ++ Africa/Casablanca and Africa/El_Aaiun in some year-2037 time ++ stamps on the reference platform. (Thanks to Alexander Belopolsky ++ for reporting the bug and suggesting a way forward.) ++ ++ If the installed localtime and/or posixrules files are symbolic ++ links, zic now keeps them symbolic links when updating them, for ++ compatibility with platforms like OpenSUSE where other programs ++ configure these files as symlinks. ++ ++ zic now avoids hard linking to symbolic links, avoids some ++ unnecessary mkdir and stat system calls, and uses shorter file ++ names internally. ++ ++ zdump has a new -i option to generate transitions in a ++ more-compact but still human-readable format. This option is ++ experimental, and the output format may change in future versions. ++ (Thanks to Jon Skeet for suggesting that an option was needed, ++ and thanks to Tim Parenti and Chris Rovick for further comments.) ++ ++ Changes to build procedure ++ ++ An experimental distribution format is available, in addition ++ to the traditional format which will continue to be distributed. ++ The new format is a tarball tzdb-VERSION.tar.lz with signature ++ file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory ++ tzdb-VERSION containing the code and data of the traditional ++ two-tarball format, along with extra data that may be useful. ++ (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others ++ for comments about the experimental format.) ++ ++ The release version number is now more accurate in the usual case ++ where releases are built from a Git repository. For example, if ++ 23 commits and some working-file changes have been made since ++ release 2016g, the version number is now something like ++ '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. ++ Official releases uses the same version number format as before, ++ e.g., '2016g'. To support the more-accurate version number, its ++ specification has moved from a line in the Makefile to a new ++ source file 'version'. ++ ++ The experimental distribution contains a file to2050.tzs that ++ contains what should be the output of 'zdump -i -c 2050' on ++ primary zones. If this file is available, 'make check' now checks ++ that zdump generates this output. ++ ++ 'make check_web' now works on Fedora-like distributions. ++ ++ Changes to documentation and commentary ++ ++ tzfile.5 now documents the new restriction on POSIX TZ-like ++ strings that is now implemented by zic. ++ ++ Comments now cite URLs for some 1917-1921 Russian DST decrees. ++ (Thanks to Alexander Belopolsky.) ++ ++ tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J ++ (thanks to Meno Hochschild) and ThreeTen-Extra, and its ++ description of Java 8 has been brought up to date (thanks to ++ Stephen Colebourne).

(Thanks to Christos Zoulas.) ++ It also includes some uses of uninitialized variables after tzalloc. ++ The new code uses the standard type 'ssize_t', which the Makefile ++ now gives porting advice about. ++ ++ Changes affecting commentary ++ ++ Updated URLs for NRC Canada (thanks to Matt Johnson and Brian Inglis). ++ ++ ++Release 2014h - 2014-09-25 18:59:03 -0700 ++ ++ Changes affecting past time stamps ++ ++ America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28. ++ ++ Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01, ++ not 1920-01-06. The old entry was based on a misinterpretation of Shanks. ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Blantyre, Africa/Bujumbura, ++ Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi, ++ Africa/Lusaka, Africa/Maseru, and Africa/Mbabane. ++ ++ Changes affecting code ++ ++ zdump -V and -v now output gmtoff= values on all platforms, ++ not merely on platforms defining TM_GMTOFF. ++ ++ The tz library's localtime and mktime functions now set tzname to a value ++ appropriate for the requested time stamp, and zdump now uses this ++ on platforms not defining TM_ZONE, fixing a 2014g regression. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ The tz library no longer sets tzname if localtime or mktime fails. ++ ++ zdump -c no longer mishandles transitions near year boundaries. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ An access to uninitialized data has been fixed. ++ (Thanks to Jörg Richter for reporting the problem.) ++ ++ When THREAD_SAFE is defined, the code ports to the C11 memory model. ++ A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined ++ and two threads race to initialize data used by gmtime-like functions. ++ (Thanks to Andy Heninger for reporting the problems.) ++ ++ Changes affecting build procedure ++ ++ 'make check' now checks better for properly-sorted data. ++ ++ Changes affecting documentation and commentary ++ ++ zdump's gmtoff=N output is now documented, and its isdst=D output ++ is now documented to possibly output D values other than 0 or 1. ++ ++ zdump -c's treatment of years is now documented to use the ++ Gregorian calendar and Universal Time without leap seconds, ++ and its behavior at cutoff boundaries is now documented better. ++ (Thanks to Arthur David Olson and Tim Parenti for reporting the problems.) ++ ++ Programs are now documented to use the proleptic Gregorian calendar. ++ (Thanks to Alan Barrett for the suggestion.) ++ ++ Fractional-second GMT offsets have been documented for civil time ++ in 19th-century Chennai, Jakarta, and New York. ++ ++ ++Release 2014g - 2014-08-28 12:31:23 -0700 ++ ++ Changes affecting future time stamps ++ ++ Turks & Caicos is switching from US eastern time to UT -04 ++ year-round, modeled as a switch on 2014-11-02 at 02:00. ++ [As noted in 2014j, this switch was later delayed.] ++ ++ Changes affecting past time stamps ++ ++ Time in Russia or the USSR before 1926 or so has been corrected by ++ a few seconds in the following zones: Asia/Irkutsk, ++ Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi, ++ Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For ++ Asia/Yekaterinburg the correction is a few minutes. (Thanks to ++ Vladimir Karpinsky.) ++ ++ The Portuguese decree of 1911-05-26 took effect on 1912-01-01. ++ This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, ++ Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912 ++ GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. ++ (Thanks to Stephen Colebourne for pointing to the decree.) ++ ++ Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59. ++ ++ A new file 'backzone' contains data which may appeal to ++ connoisseurs of old time stamps, although it is out of scope for ++ the tz database, is often poorly sourced, and contains some data ++ that is known to be incorrect. The new file is not recommended ++ for ordinary use and its entries are not installed by default. ++ (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and ++ Isle of Man entries.) ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Bangui, Africa/Brazzaville, ++ Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, ++ Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. ++ ++ Changes affecting code ++ ++ Unless NETBSD_INSPIRED is defined to 0, the tz library now ++ supplies functions for creating and using objects that represent ++ time zones. The new functions are tzalloc, tzfree, localtime_rz, ++ mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and ++ time2posix_z. They are intended for performance: for example, ++ localtime_rz (unlike localtime_r) is trivially thread-safe without ++ locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired ++ functions, and to Alan Barrett and Jonathan Lennox for helping to ++ debug the change.) ++ ++ zdump now builds with the tz library unless USE_LTZ is defined to 0, ++ This lets zdump use tz features even if the system library lacks them. ++ To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 ++ TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. ++ ++ zdump now uses localtime_rz if available, as it's significantly faster, ++ and it can help zdump better diagnose invalid time zone names. ++ Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ ++ defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is ++ not available, zdump now uses localtime_r and tzset if available, ++ as this is a bit cleaner and faster than plain localtime. Compile ++ with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system ++ lacks these two functions. ++ ++ If THREAD_SAFE is defined to 1, the tz library is now thread-safe. ++ Although not needed for tz's own applications, which are single-threaded, ++ this supports POSIX better if the tz library is used in multithreaded apps. ++ ++ Some crashes have been fixed when zdump or the tz library is given ++ invalid or outlandish input. ++ ++ The tz library no longer mishandles leap seconds on platforms with ++ unsigned time_t in time zones that lack ordinary transitions after 1970. ++ ++ The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not ++ already defined, to make it easier to configure on common platforms. ++ Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. ++ ++ Unless the new macro UNINIT_TRAP is defined to 1, the tz code now ++ assumes that reading uninitialized memory yields garbage values ++ but does not cause other problems such as traps. ++ ++ If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now ++ more likely to guess right for ambiguous time stamps near ++ transitions where tm_isdst does not change. ++ ++ If HAVE_STRFTIME_L is defined to 1, the tz library now defines ++ strftime_l for compatibility with recent versions of POSIX. ++ Only the C locale is supported, though. HAVE_STRFTIME_L defaults ++ to 1 on recent POSIX versions, and to 0 otherwise. ++ ++ tzselect -c now uses a hybrid distance measure that works better ++ in Africa. (Thanks to Alan Barrett for noting the problem.) ++ ++ The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, ++ or when time_tz is defined. ++ ++ When HAVE_UTMPX_H is set the 'date' command now builds on systems ++ whose <utmpx.h> file does not define WTMPX_FILE, and when setting ++ the date it updates the wtmpx file if _PATH_WTMPX is defined. ++ This affects GNU/Linux and similar systems. ++ ++ For easier maintenance later, some C code has been simplified, ++ some lint has been removed, and the code has been tweaked so that ++ plain 'make' is more likely to work. ++ ++ The C type 'bool' is now used for boolean values, instead of 'int'. ++ ++ The long-obsolete LOCALE_HOME code has been removed. ++ ++ The long-obsolete 'gtime' function has been removed. ++ ++ Changes affecting build procedure ++ ++ 'zdump' no longer links in ialloc.o, as it's not needed. ++ ++ 'make check_time_t_alternatives' no longer assumes GNU diff. ++ ++ Changes affecting distribution tarballs ++ ++ The files checktab.awk and zoneinfo2tdf.pl are now distributed in ++ the tzdata tarball instead of the tzcode tarball, since they help ++ maintain the data. The NEWS and Theory files are now also ++ distributed in the tzdata tarball, as they're relevant for data. ++ (Thanks to Alan Barrett for pointing this out.) Also, the ++ leapseconds.awk file is no longer distributed in the tzcode ++ tarball, since it belongs in the tzdata tarball (where 2014f ++ inadvertently also distributed it). ++ ++ Changes affecting documentation and commentary ++ ++ A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for ++ suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms ++ for debugging it.) ++ ++ The man pages have been updated to use function prototypes, ++ to document thread-safe variants like localtime_r, and to document ++ the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and ++ mktime_z. ++ ++ The fields in Link lines have been renamed to be more descriptive ++ and more like the parameters of 'ln'. LINK-FROM has become TARGET, ++ and LINK-TO has become LINK-NAME. ++ ++ tz-link.htm mentions the IETF's tzdist working group; Windows ++ Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. ++ ++ Some broken URLs have been fixed in the commentary. (Thanks to ++ Lester Caine.) ++ ++ Commentary about Philippines DST has been updated, and commentary ++ on pre-1970 time in India has been added. ++ ++ ++Release 2014f - 2014-08-05 17:42:36 -0700 ++ ++ Changes affecting future time stamps ++ ++ Russia will subtract an hour from most of its time zones on 2014-10-26 ++ at 02:00 local time. (Thanks to Alexander Krivenyshev.) ++ There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky ++ Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug ++ (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast ++ (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic ++ (Europe/Samara) are not changing their clocks. The changed zones are ++ Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, ++ Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, ++ Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, ++ Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours ++ subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, ++ but not its UTC offset. Two zones are added: Asia/Chita (split ++ from Asia/Yakutsk, and also with two hours subtracted) and ++ Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour ++ subtracted). (Thanks to Tim Parenti for much of the above.) ++ ++ Changes affecting time zone abbreviations ++ ++ Australian eastern time zone abbreviations are now AEST/AEDT not EST, ++ and similarly for the other Australian zones. That is, for eastern ++ standard and daylight saving time the abbreviations are AEST and AEDT ++ instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT, ++ and AWST/AWDT are now used instead of the former CST, CWST, and WST. ++ This change does not affect UTC offsets, only time zone abbreviations. ++ (Thanks to Rich Tibbett and many others.) ++ ++ Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UT +07) ++ effective 2014-10-26 at 02:00 local time. ++ ++ The time zone abbreviation for Xinjiang Time (observed in Ürümqi) ++ has been changed from URUT to XJT. (Thanks to Luther Ma.) ++ ++ Prefer MSK/MSD for Moscow time in Russia, even in other cities. ++ Similarly, prefer EET/EEST for eastern European time in Russia. ++ ++ Change time zone abbreviations in (western) Samoa to use "ST" and ++ "DT" suffixes, as this is more likely to match common practice. ++ Prefix "W" to (western) Samoa time when its standard-time offset ++ disagrees with that of American Samoa. ++ ++ America/Metlakatla now uses PST, not MeST, to abbreviate its time zone. ++ ++ Time zone abbreviations have been updated for Japan's two time ++ zones used 1896-1937. JWST now stands for Western Standard ++ Time, and JCST for Central Standard Time (formerly this was CJT). ++ These abbreviations are now used for time in Korea, Taiwan, ++ and Sakhalin while controlled by Japan. ++ ++ Changes affecting past time stamps ++ ++ China's five zones have been simplified to two, since the post-1970 ++ differences in the other three seem to have been imaginary. The ++ zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been ++ removed; backwards-compatibility links still work, albeit with ++ different behaviors for time stamps before May 1980. Asia/Urumqi's ++ 1980 transition to UT +08 has been removed, so that it is now at ++ +06 and not +08. (Thanks to Luther Ma and to Alois Treindl; ++ Treindl sent helpful translations of two papers by Guo Qingsheng.) ++ ++ Some zones have been turned into links, when they differed from existing ++ zones only for older UTC offsets where data entries were likely invented. ++ These changes affect UTC offsets in pre-1970 time stamps only. This is ++ similar to the change in release 2013e, except this time for western ++ Africa. The affected zones are: Africa/Bamako, Africa/Banjul, ++ Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, ++ Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and ++ Atlantic/St_Helena. This also affects the backwards-compatibility ++ link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, ++ Tim Parenti, and David Patte for reporting problems in earlier ++ versions of this change.) ++ ++ Asia/Shanghai's pre-standard-time UT offset has been changed from ++ 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its ++ transition to standard time has been changed from 1928 to 1901. ++ ++ Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, ++ then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. ++ In 1946 it observed DST from 05-15 through 09-30; in 1947 ++ from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. ++ (Thanks to Yu-Cheng Chuang.) ++ ++ Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. ++ ++ Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not ++ 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) ++ ++ Pacific/Pago_Pago has been changed from UT -11:30 to -11 for the ++ period from 1911 to 1950. ++ ++ Pacific/Chatham has been changed to New Zealand standard time plus ++ 45 minutes for the period before 1957, reflecting a 1956 remark in ++ the New Zealand parliament. ++ ++ Europe/Budapest has several pre-1946 corrections: in 1918 the transition ++ out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in ++ 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 ++ not 04-06 at 02:00; and there was no DST in 1920. ++ ++ Africa/Accra is now assumed to have observed DST from 1920 through 1935. ++ ++ Time in Russia before 1927 or so has been corrected by a few seconds in ++ the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, ++ Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and ++ Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 ++ point. (Thanks to Vladimir Karpinsky for the Moscow changes.) ++ ++ Changes affecting data format ++ ++ A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. ++ The new file's extended format allows multiple country codes per zone. ++ The older file is still installed but is deprecated; its format is ++ not changing and it will still be distributed for a while, but new ++ applications should use the new file. ++ ++ The new file format simplifies maintenance of obscure locations. ++ To test this, it adds coverage for the Crozet Islands and the ++ Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) ++ ++ The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. ++ It is still ASCII now, but commentary about the switch has been added. ++ The new file 'zone1970.tab' already uses UTF-8. ++ ++ Changes affecting code ++ ++ 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE ++ is defined. (Thanks to Elliott Hughes for reporting the problem.) ++ ++ 'zic' no longer mishandles input when ignoring case in locales that ++ are not compatible with English, e.g., unibyte Turkish locales when ++ compiled with HAVE_GETTEXT. ++ ++ Error diagnostics of 'zic' and 'yearistype' have been reworded so that ++ they no longer use ASCII '-' as if it were a dash. ++ ++ 'zic' now rejects output file names that contain '.' or '..' components. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ 'zic -v' now warns about output file names that do not follow ++ POSIX rules, or that contain a digit or '.'. (Thanks to Arthur ++ David Olson for starting the ball rolling on this.) ++ ++ Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. ++ ++ Changes affecting build procedure ++ ++ 'zic' no longer links in localtime.o and asctime.o, as they're not needed. ++ (Thanks to John Cochran.) ++ ++ Changes affecting documentation and commentary ++ ++ The 'Theory' file documents legacy names, the longstanding ++ exceptions to the POSIX-inspired file name rules. ++ ++ The 'zic' documentation clarifies the role of time types when ++ interpreting dates. (Thanks to Arthur David Olson.) ++ ++ Documentation and commentary now prefer UTF-8 to US-ASCII, ++ allowing the use of proper accents in foreign words and names. ++ Code and data have not changed because of this. (Thanks to ++ Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug ++ this.) ++ ++ Non-HTML documentation and commentary now use plain-text URLs instead of ++ HTML insertions, and are more consistent about bracketing URLs when they ++ are not already surrounded by white space. (Thanks to suggestions by ++ Steffen Nurpmeso.) ++ ++ There is new commentary about Xujiahui Observatory, the five time-zone ++ project in China from 1918 to 1949, timekeeping in Japanese-occupied ++ Shanghai, and Tibet Time in the 1950s.

(Thanks to Michael Forney.) ++ ++ A dependency typo in the 'zdump' rule has been fixed. ++ (Thanks to Andrew Paprocki.) ++ ++ The Makefile has been simplified by assuming that 'mkdir -p' and 'cp -f' ++ work as specified by POSIX.2-1992 or later; this is portable nowadays. ++ ++ 'make clean' no longer removes 'leapseconds', since it's ++ host-independent and is part of the distribution. ++ ++ The unused makefile macros TZCSRCS, TZDSRCS, DATESRCS have been removed. ++ ++ Changes affecting documentation and commentary ++ ++ tz-link.htm now mentions TC TIMEZONE's draft time zone service protocol ++ (thanks to Mike Douglass) and TimezoneJS.Date (thanks to Jim Fehrle). ++ ++ Update URLs in tz-link page. Add URLs for Microsoft Windows, since ++ 8.1 introduces tz support. Remove URLs for Tru64 and UnixWare (no ++ longer maintained) and for old advisories. SOFA now does C. ++ ++Release 2013g - 2013-09-30 21:08:26 -0700 ++ ++ Changes affecting current and near-future time stamps ++ ++ Morocco now observes DST from the last Sunday in March to the last ++ Sunday in October, not April to September respectively. (Thanks ++ to Steffen Thorsen.) ++ ++ Changes affecting 'zic' ++ ++ 'zic' now runs on platforms that lack both hard links and symlinks. ++ (Thanks to Theo Veenker for reporting the problem, for MinGW.) ++ Also, fix some bugs on platforms that lack hard links but have symlinks. ++ ++ 'zic -v' again warns that Asia/Tehran has no POSIX environment variable ++ to predict the far future, fixing a bug introduced in 2013e. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is again put into the tzdata tarball. ++ Also, 'leapseconds.awk', so tzdata is self-contained. (Thanks to ++ Matt Burgess and Ian Abbott.) The timestamps of these and other ++ dependent files in tarballs are adjusted more consistently. ++ ++ Changes affecting documentation and commentary ++ ++ The README file is now part of the data tarball as well as the code. ++ It now states that files are public domain unless otherwise specified. ++ (Thanks to Andrew Main (Zefram) for asking for clarifications.) ++ Its details about the 1989 release moved to a place of honor near ++ the end of NEWS. ++ ++ ++Release 2013f - 2013-09-24 23:37:36 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Tocantins will very likely not observe DST starting this spring. ++ (Thanks to Steffen Thorsen.) ++ ++ Jordan will likely stay at UT +03 indefinitely, and will not fall ++ back this fall. ++ ++ Palestine will fall back at 00:00, not 01:00. (Thanks to Steffen Thorsen.) ++ ++ Changes affecting API ++ ++ The types of the global variables 'timezone' and 'altzone' (if present) ++ have been changed back to 'long'. This is required for 'timezone' ++ by POSIX, and for 'altzone' by common practice, e.g., Solaris 11. ++ These variables were originally 'long' in the tz code, but were ++ mistakenly changed to 'time_t' in 1987; nobody reported the ++ incompatibility until now. The difference matters on x32, where ++ 'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.) ++ ++ Changes affecting the build procedure ++ ++ Avoid long strings in leapseconds.awk to work around a mawk bug. ++ (Thanks to Cyril Baurand.) ++ ++ Changes affecting documentation and commentary ++ ++ New file 'NEWS' that contains release notes like this one. ++ ++ Paraguay's law does not specify DST transition time; 00:00 is customary. ++ (Thanks to Waldemar Villamayor-Venialbo.) ++ ++ Minor capitalization fixes. ++ ++ Changes affecting version-control only ++ ++ The experimental GitHub repository now contains annotated and ++ signed tags for recent releases, e.g., '2013e' for Release 2013e. ++ Releases are tagged starting with 2012e; earlier releases were ++ done differently, and tags would either not have a simple name or ++ not exactly match what was released. ++ ++ 'make set-timestamps' is now simpler and a bit more portable. ++ ++ ++Release 2013e - 2013-09-19 23:50:04 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ This year Fiji will start DST on October 27, not October 20. ++ (Thanks to David Wheeler for the heads-up.) For now, guess that ++ Fiji will continue to spring forward the Sunday before the fourth ++ Monday in October. ++ ++ Changes affecting current and future time zone abbreviations ++ ++ Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian ++ time zone abbreviations since 1932. (Thanks to George Ziegler, ++ Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and ++ Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, ++ Asia/Makassar, and Asia/Pontianak. ++ ++ Use ART (UT -03, standard time), rather than WARST (also -03, but ++ daylight saving time) for San Luis, Argentina since 2009. ++ ++ Changes affecting Godthåb time stamps after 2037 if version mismatch ++ ++ Allow POSIX-like TZ strings where the transition time's hour can ++ range from -167 through 167, instead of the POSIX-required 0 ++ through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the ++ new Fiji rules. This is a more-compact way to represent ++ far-future time stamps for America/Godthab, America/Santiago, ++ Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, ++ Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by ++ this change. (Derived from a suggestion by Arthur David Olson.) ++ ++ Allow POSIX-like TZ strings where daylight saving time is in ++ effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western ++ Argentina Summer Time all year. This supports a more-compact way ++ to represent the 2013d data for America/Argentina/San_Luis. ++ Because of the change for San Luis noted above this change does not ++ affect the current data. (Thanks to Andrew Main (Zefram) for ++ suggestions that improved this change.) ++ ++ Where these two TZ changes take effect, there is a minor extension ++ to the tz file format in that it allows new values for the ++ embedded TZ-format string, and the tz file format version number ++ has therefore been increased from 2 to 3 as a precaution. ++ Version-2-based client code should continue to work as before for ++ all time stamps before 2038. Existing version-2-based client code ++ (tzcode, GNU/Linux, Solaris) has been tested on version-3-format ++ files, and typically works in practice even for time stamps after ++ 2037; the only known exception is America/Godthab. ++ ++ Changes affecting time stamps before 1970 ++ ++ Pacific/Johnston is now a link to Pacific/Honolulu. This corrects ++ some errors before 1947. ++ ++ Some zones have been turned into links, when they differ from existing ++ zones only in older data entries that were likely invented or that ++ differ only in LMT or transitions from LMT. These changes affect ++ only time stamps before 1943. The affected zones are: ++ Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, ++ America/Grenada, America/Guadeloupe, America/Marigot, ++ America/Montserrat, America/St_Barthelemy, America/St_Kitts, ++ America/St_Lucia, America/St_Thomas, America/St_Vincent, ++ America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for ++ confirming that the old Europe/Vaduz zone was wrong and the new ++ link is better for WWII-era times.) ++ ++ Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects ++ America/Cayman, America/Jamaica and America/Grand_Turk time stamps ++ from 1890 to 1912. ++ ++ Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. ++ This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks ++ to Alois Treindl). ++ ++ Change the date of the circa-1850 Zurich transition from 1849-09-12 ++ to 1853-07-16, overriding Shanks with data from Messerli about ++ postal and telegraph time in Switzerland. ++ ++ Changes affecting time zone abbreviations before 1970 ++ ++ For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, ++ as Jakarta was called Batavia back then. ++ ++ Changes affecting API ++ ++ The 'zic' command now outputs a dummy transition when far-future ++ data can't be summarized using a TZ string, and uses a 402-year ++ window rather than a 400-year window. For the current data, this ++ affects only the Asia/Tehran file. It does not affect any of the ++ time stamps that this file represents, so zdump outputs the same ++ information as before. (Thanks to Andrew Main (Zefram).) ++ ++ The 'date' command has a new '-r' option, which lets you specify ++ the integer time to display, a la FreeBSD. ++ ++ The 'tzselect' command has two new options '-c' and '-n', which lets you ++ select a zone based on latitude and longitude. ++ ++ The 'zic' command's '-v' option now warns about constructs that ++ require the new version-3 binary file format. (Thanks to Arthur ++ David Olson for the suggestion.) ++ ++ Support for floating-point time_t has been removed. ++ It was always dicey, and POSIX no longer requires it. ++ (Thanks to Eric Blake for suggesting to the POSIX committee to ++ remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy ++ Heninger, Arthur David Olson, and Alois Treindl, for reporting ++ bugs and elucidating some of the corners of the old floating-point ++ implementation.) ++ ++ The signatures of 'offtime', 'timeoff', and 'gtime' have been ++ changed back to the old practice of using 'long' to represent UT ++ offsets. This had been inadvertently and mistakenly changed to ++ 'int_fast32_t'. (Thanks to Christos Zoulas.) ++ ++ The code avoids undefined behavior on integer overflow in some ++ more places, including gmtime, localtime, mktime and zdump. ++ ++ Changes affecting the zdump utility ++ ++ zdump now outputs "UT" when referring to Universal Time, not "UTC". ++ "UTC" does not make sense for time stamps that predate the introduction ++ of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen ++ for clarifying UT vs UTC.) ++ ++ Data changes affecting behavior of tzselect and similar programs ++ ++ Country code BQ is now called the more-common name "Caribbean Netherlands" ++ rather than the more-official "Bonaire, St Eustatius & Saba". ++ ++ Remove from zone.tab the names America/Montreal, America/Shiprock, ++ and Antarctica/South_Pole, as they are equivalent to existing ++ same-country-code zones for post-1970 time stamps. The data entries for ++ these names are unchanged, so the names continue to work as before. ++ ++ Changes affecting code internals ++ ++ zic -c now runs way faster on 64-bit hosts when given large numbers. ++ ++ zic now uses vfprintf to avoid allocating and freeing some memory. ++ ++ tzselect now computes the list of continents from the data, ++ rather than have it hard-coded. ++ ++ Minor changes pacify GCC 4.7.3 and GCC 4.8.1. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is now generated automatically from a ++ new file 'leap-seconds.list', which is a copy of ++ <ftp://time.nist.gov/pub/leap-seconds.list>. ++ A new source file 'leapseconds.awk' implements this. ++ The goal is simplification of the future maintenance of 'leapseconds'. ++ ++ When building the 'posix' or 'right' subdirectories, if the ++ subdirectory would be a copy of the default subdirectory, it is ++ now made a symbolic link if that is supported. This saves about ++ 2 MB of file system space. ++ ++ The links America/Shiprock and Antarctica/South_Pole have been ++ moved to the 'backward' file. This affects only nondefault builds ++ that omit 'backward'. ++ ++ Changes affecting version-control only ++ ++ .gitignore now ignores 'date'. ++ ++ Changes affecting documentation and commentary ++ ++ Changes to the 'tzfile' man page ++ ++ It now mentions that the binary file format may be extended in ++ future versions by appending data. ++ ++ It now refers to the 'zdump' and 'zic' man pages. ++ ++ Changes to the 'zic' man page ++ ++ It lists conditions that elicit a warning with '-v'. ++ ++ It says that the behavior is unspecified when duplicate names ++ are given, or if the source of one link is the target of another. ++ ++ Its examples are updated to match the latest data. ++ ++ The definition of white space has been clarified slightly. ++ (Thanks to Michael Deckers.) ++ ++ Changes to the 'Theory' file ++ ++ There is a new section about the accuracy of the tz database, ++ describing the many ways that errors can creep in, and ++ explaining why so many of the pre-1970 time stamps are wrong or ++ misleading (thanks to Steve Allen, Lester Caine, and Garrett ++ Wollman for discussions that contributed to this). ++ ++ The 'Theory' file describes LMT better (this follows a ++ suggestion by Guy Harris). ++ ++ It refers to the 2013 edition of POSIX rather than the 2004 edition. ++ ++ It's mentioned that excluding 'backward' should not affect the ++ other data, and it suggests at least one zone.tab name per ++ inhabited country (thanks to Stephen Colebourne). ++ ++ Some longstanding restrictions on names are documented, e.g., ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ ++ It gives more reasons for the 1970 cutoff. ++ ++ It now mentions which time_t variants are supported, such as ++ signed integer time_t. (Thanks to Paul Goyette for reporting ++ typos in an experimental version of this change.) ++ ++ (Thanks to Philip Newton for correcting typos in these changes.) ++ ++ Documentation and commentary is more careful to distinguish UT in ++ general from UTC in particular. (Thanks to Steve Allen.) ++ ++ Add a better source for the Zurich 1894 transition. ++ (Thanks to Pierre-Yves Berger.) ++ ++ Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.) ++ ++ ++Release 2013d - 2013-07-05 07:38:01 -0700 ++ ++ Changes affecting future time stamps: ++ ++ Morocco's midsummer transitions this year are July 7 and August 10, ++ not July 9 and August 8. (Thanks to Andrew Paprocki.) ++ ++ Israel now falls back on the last Sunday of October. ++ (Thanks to Ephraim Silverberg.) ++ ++ Changes affecting past time stamps: ++ ++ Specify Jerusalem's location more precisely; this changes the pre-1880 ++ times by 2 s. ++ ++ Changing affecting metadata only: ++ ++ Fix typos in the entries for country codes BQ and SX. ++ ++ Changes affecting code: ++ ++ Rework the code to fix a bug with handling Australia/Macquarie on ++ 32-bit hosts (thanks to Arthur David Olson). ++ ++ Port to platforms like NetBSD, where time_t can be wider than long. ++ ++ Add support for testing time_t types other than the system's. ++ Run 'make check_time_t_alternatives' to try this out. ++ Currently, the tests fail for unsigned time_t; ++ this should get fixed at some point. ++ ++ Changes affecting documentation and commentary: ++ ++ Deemphasize the significance of national borders. ++ ++ Update the zdump man page. ++ ++ Remove obsolete NOID comment (thanks to Denis Excoffier). ++ ++ Update several URLs and comments in the web pages. ++ ++ Spelling fixes (thanks to Kevin Lyda and Jonathan Leffler). ++ ++ Update URL for CLDR Zone->Tzid table (thanks to Yoshito Umaoka). ++ ++ ++Release 2013c - 2013-04-19 16:17:40 -0700 ++ ++ Changes affecting current and future time stamps: ++ ++ Palestine observed DST starting March 29, 2013.

Second, the Pridnestrovian Moldavian Republic ++ (Europe/Tiraspol) decided not to split from the rest of Moldova after ++ all, and consequently that zone has been removed (again) and reinstated ++ in the "backward" file as a link to Europe/Chisinau. And third, the ++ end date for Fiji's summer time this summer was moved forward from the ++ earlier planned Feb 26, to Jan 22. ++ ++ Apart from that, Moldova (MD) returns to a single entry in zone.tab ++ (and the incorrect syntax that was in the 2011m version of that file ++ is so fixed - it would have been fixed in a different way had this ++ change not happened - that's the "missing" sccs version id). ++ ++ ++Release data2011m - 2011-10-24 21:42:16 +0700 ++ ++ In particular, the typos in comments in the data (2011-11-17 should have ++ been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that ++ Tim Parenti noted) have been fixed, and the change for Ukraine has been ++ made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to ++ Tim Parenti, and also Denys Gavrysh) ++ ++ In addition, I added Europe/Tiraspol to zone.tab. ++ ++ This time, all the files have new version numbers...

The text has been ++adapted and reformatted for the purposes of this file. ++ ++Traditionally a release R consists of a pair of tarball files, ++tzcodeR.tar.gz and tzdataR.tar.gz. However, some releases (e.g., ++code2010a, data2012c) consist of just one or the other tarball, and a ++few (e.g., code2012c-data2012d) have tarballs with mixed version ++numbers. Recent releases also come in an experimental format ++consisting of a single tarball tzdb-R.tar.lz with extra data. ++ ++Release time stamps are taken from the release's commit (for newer, ++Git-based releases), from the newest file in the tarball (for older ++releases, where this info is available) or from the email announcing ++the release (if all else fails; these are marked with a time zone of ++-0000 and an "is missing!" comment). ++ ++Earlier versions of the code and data were not announced on the tz ++list and are not summarized here. ++ ++This file is in the public domain. ++ ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/README.orig ++++ contrib/tzdata/README +@@ -0,0 +1,71 @@ ++README for the tz distribution ++ ++"What time is it?" -- Richard Deacon as The King ++"Any time you want it to be." -- Frank Baxter as The Scientist ++ (from the Bell System film "About Time") ++ ++The Time Zone Database (often called tz or zoneinfo) contains code and ++data that represent the history of local time for many representative ++locations around the globe.

To represent this ++data, the world is partitioned into regions whose clocks all agree ++about time stamps that occur after the somewhat-arbitrary cutoff point ++of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region, ++the database records all known clock transitions, and labels the region ++with a notable location. Although 1970 is a somewhat-arbitrary ++cutoff, there are significant challenges to moving the cutoff earlier ++even by a decade or two, due to the wide variety of local practices ++before computer timekeeping became prevalent. ++ ++Clock transitions before 1970 are recorded for each such location, ++because most systems support time stamps before 1970 and could ++misbehave if data entries were omitted for pre-1970 transitions. ++However, the database is not designed for and does not suffice for ++applications requiring accurate handling of all past times everywhere, ++as it would take far too much effort and guesswork to record all ++details of pre-1970 civil timekeeping. ++ ++As described below, reference source code for using the tz database is ++also available. The tz code is upwards compatible with POSIX, an ++international standard for UNIX-like systems. As of this writing, the ++current edition of POSIX is: ++ ++ The Open Group Base Specifications Issue 7 ++ IEEE Std 1003.1, 2013 Edition ++ <http://pubs.opengroup.org/onlinepubs/9699919799/> ++ ++ ++ ++----- Names of time zone rules ----- ++ ++Each of the database's time zone rules has a unique name. ++Inexperienced users are not expected to select these names unaided. ++Distributors should provide documentation and/or a simple selection ++interface that explains the names; for one example, see the 'tzselect' ++program in the tz code. The Unicode Common Locale Data Repository ++<http://cldr.unicode.org/> contains data that may be useful for other ++selection interfaces. ++ ++The time zone rule naming conventions attempt to strike a balance ++among the following goals: ++ ++ * Uniquely identify every region where clocks have agreed since 1970. ++ This is essential for the intended use: static clocks keeping local ++ civil time. ++ ++ * Indicate to experts where that region is. ++ ++ * Be robust in the presence of political changes. For example, names ++ of countries are ordinarily not used, to avoid incompatibilities ++ when countries change their name (e.g. Zaire->Congo) or when ++ locations change countries (e.g. Hong Kong from UK colony to ++ China). ++ ++ * Be portable to a wide variety of implementations. ++ ++ * Use a consistent naming conventions over the entire world. ++ ++Names normally have the form AREA/LOCATION, where AREA is the name ++of a continent or ocean, and LOCATION is the name of a specific ++location within that region. North and South America share the same ++area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York', ++and 'Pacific/Honolulu'. ++ ++Here are the general rules used for choosing location names, ++in decreasing order of importance: ++ ++ Use only valid POSIX file name components (i.e., the parts of ++ names other than '/'). Do not use the file name ++ components '.' and '..'. Within a file name component, ++ use only ASCII letters, '.', '-' and '_'. Do not use ++ digits, as that might create an ambiguity with POSIX ++ TZ strings. A file name component must not exceed 14 ++ characters or start with '-'. E.g., prefer 'Brunei' ++ to 'Bandar_Seri_Begawan'. Exceptions: see the discussion ++ of legacy names below. ++ A name must not be empty, or contain '//', or start or end with '/'. ++ Do not use names that differ only in case. Although the reference ++ implementation is case-sensitive, some other implementations ++ are not, and they would mishandle names differing only in case. ++ If one name A is an initial prefix of another name AB (ignoring case), ++ then B must not start with '/', as a regular file cannot have ++ the same name as a directory in POSIX. For example, ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ Uninhabited regions like the North Pole and Bouvet Island ++ do not need locations, since local time is not defined there. ++ There should typically be at least one name for each ISO 3166-1 ++ officially assigned two-letter code for an inhabited country ++ or territory. ++ If all the clocks in a region have agreed since 1970, ++ don't bother to include more than one location ++ even if subregions' clocks disagreed before 1970. ++ Otherwise these tables would become annoyingly large. ++ If a name is ambiguous, use a less ambiguous alternative; ++ e.g. many cities are named San José and Georgetown, so ++ prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'. ++ Keep locations compact. Use cities or small islands, not countries ++ or regions, so that any future time zone changes do not split ++ locations into different time zones. E.g. prefer 'Paris' ++ to 'France', since France has had multiple time zones. ++ Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and ++ prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'. ++ The POSIX file name restrictions encourage this rule. ++ Use the most populous among locations in a zone, ++ e.g. prefer 'Shanghai' to 'Beijing'. Among locations with ++ similar populations, pick the best-known location, ++ e.g. prefer 'Rome' to 'Milan'. ++ Use the singular form, e.g. prefer 'Canary' to 'Canaries'. ++ Omit common suffixes like '_Islands' and '_City', unless that ++ would lead to ambiguity. E.g. prefer 'Cayman' to ++ 'Cayman_Islands' and 'Guatemala' to 'Guatemala_City', ++ but prefer 'Mexico_City' to 'Mexico' because the country ++ of Mexico has several time zones. ++ Use '_' to represent a space. ++ Omit '.' from abbreviations in names, e.g. prefer 'St_Helena' ++ to 'St._Helena'. ++ Do not change established names if they only marginally ++ violate the above rules. For example, don't change ++ the existing name 'Rome' to 'Milan' merely because ++ Milan's population has grown to be somewhat greater ++ than Rome's. ++ If a name is changed, put its old spelling in the 'backward' file. ++ This means old spellings will continue to work. ++ ++The file 'zone1970.tab' lists geographical locations used to name time ++zone rules. It is intended to be an exhaustive list of names for ++geographic regions as described above; this is a subset of the names ++in the data. Although a 'zone1970.tab' location's longitude ++corresponds to its LMT offset with one hour for every 15 degrees east ++longitude, this relationship is not exact. ++ ++Older versions of this package used a different naming scheme, ++and these older names are still supported. ++See the file 'backward' for most of these older names ++(e.g., 'US/Eastern' instead of 'America/New_York'). ++The other old-fashioned names still supported are ++'WET', 'CET', 'MET', and 'EET' (see the file 'europe'). ++ ++Older versions of this package defined legacy names that are ++incompatible with the first rule of location names, but which are ++still supported. These legacy names are mostly defined in the file ++'etcetera'. Also, the file 'backward' defines the legacy names ++'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file ++'northamerica' defines the legacy names 'EST5EDT', 'CST6CDT', ++'MST7MDT', and 'PST8PDT'. ++ ++Excluding 'backward' should not affect the other data. If ++'backward' is excluded, excluding 'etcetera' should not affect the ++remaining data. ++ ++ ++----- Time zone abbreviations ----- ++ ++When this package is installed, it generates time zone abbreviations ++like 'EST' to be compatible with human tradition and POSIX. ++Here are the general rules used for choosing time zone abbreviations, ++in decreasing order of importance: ++ ++ Use three or more characters that are ASCII alphanumerics or '+' or '-'. ++ Previous editions of this database also used characters like ++ ' ' and '?', but these characters have a special meaning to ++ the shell and cause commands like ++ set `date` ++ to have unexpected effects. ++ Previous editions of this rule required upper-case letters, ++ but the Congressman who introduced Chamorro Standard Time ++ preferred "ChST", so lower-case letters are now allowed. ++ Also, POSIX from 2001 on relaxed the rule to allow '-', '+', ++ and alphanumeric characters from the portable character set ++ in the current locale. In practice ASCII alphanumerics and ++ '+' and '-' are safe in all locales. ++ ++ In other words, in the C locale the POSIX extended regular ++ expression [-+[:alnum:]]{3,} should match the abbreviation. ++ This guarantees that all abbreviations could have been ++ specified by a POSIX TZ string. ++ ++ Use abbreviations that are in common use among English-speakers, ++ e.g. 'EST' for Eastern Standard Time in North America. ++ We assume that applications translate them to other languages ++ as part of the normal localization process; for example, ++ a French application might translate 'EST' to 'HNE'. ++ ++ For zones whose times are taken from a city's longitude, use the ++ traditional xMT notation, e.g. 'PMT' for Paris Mean Time. ++ The only name like this in current use is 'GMT'. ++ ++ Use 'LMT' for local mean time of locations before the introduction ++ of standard time; see "Scope of the tz database". ++ ++ If there is no common English abbreviation, use numeric offsets like ++ -05 and +0830 that are generated by zic's %z notation. ++ ++ [The remaining guidelines predate the introduction of %z. ++ They are problematic as they mean tz data entries invent ++ notation rather than record it. These guidelines are now ++ deprecated and the plan is to gradually move to %z for ++ inhabited locations and to "-00" for uninhabited locations.] ++ ++ If there is no common English abbreviation, abbreviate the English ++ translation of the usual phrase used by native speakers. ++ If this is not available or is a phrase mentioning the country ++ (e.g. "Cape Verde Time"), then: ++ ++ When a country is identified with a single or principal zone, ++ append 'T' to the country's ISO code, e.g. 'CVT' for ++ Cape Verde Time. For summer time append 'ST'; ++ for double summer time append 'DST'; etc. ++ Otherwise, take the first three letters of an English place ++ name identifying each zone and append 'T', 'ST', etc. ++ as before; e.g. 'VLAST' for VLAdivostok Summer Time. ++ ++ Use UT (with time zone abbreviation '-00') for locations while ++ uninhabited. The leading '-' is a flag that the time ++ zone is in some sense undefined; this notation is ++ derived from Internet RFC 3339. ++ ++Application writers should note that these abbreviations are ambiguous ++in practice: e.g. 'CST' has a different meaning in China than ++it does in the United States. In new applications, it's often better ++to use numeric UT offsets like '-0600' instead of time zone ++abbreviations like 'CST'; this avoids the ambiguity. ++ ++ ++----- Accuracy of the tz database ----- ++ ++The tz database is not authoritative, and it surely has errors. ++Corrections are welcome and encouraged; see the file CONTRIBUTING. ++Users requiring authoritative data should consult national standards ++bodies and the references cited in the database's comments. ++ ++Errors in the tz database arise from many sources: ++ ++ * The tz database predicts future time stamps, and current predictions ++ will be incorrect after future governments change the rules. ++ For example, if today someone schedules a meeting for 13:00 next ++ October 1, Casablanca time, and tomorrow Morocco changes its ++ daylight saving rules, software can mess up after the rule change ++ if it blithely relies on conversions made before the change. ++ ++ * The pre-1970 entries in this database cover only a tiny sliver of how ++ clocks actually behaved; the vast majority of the necessary ++ information was lost or never recorded. Thousands more zones would ++ be needed if the tz database's scope were extended to cover even ++ just the known or guessed history of standard time; for example, ++ the current single entry for France would need to split into dozens ++ of entries, perhaps hundreds. And in most of the world even this ++ approach would be misleading due to widespread disagreement or ++ indifference about what times should be observed. In her 2015 book ++ "The Global Transformation of Time, 1870-1950", Vanessa Ogle writes ++ "Outside of Europe and North America there was no system of time ++ zones at all, often not even a stable landscape of mean times, ++ prior to the middle decades of the twentieth century". See: ++ Timothy Shenk, Booked: A Global History of Time. Dissent 2015-12-17 ++ https://www.dissentmagazine.org/blog/booked-a-global-history-of-time-vanessa-ogle ++ ++ * Most of the pre-1970 data entries come from unreliable sources, often ++ astrology books that lack citations and whose compilers evidently ++ invented entries when the true facts were unknown, without ++ reporting which entries were known and which were invented. ++ These books often contradict each other or give implausible entries, ++ and on the rare occasions when they are checked they are ++ typically found to be incorrect. ++ ++ * For the UK the tz database relies on years of first-class work done by ++ Joseph Myers and others; see <http://www.polyomino.org.uk/british-time/>. ++ Other countries are not done nearly as well. ++ ++ * Sometimes, different people in the same city would maintain clocks ++ that differed significantly. Railway time was used by railroad ++ companies (which did not always agree with each other), ++ church-clock time was used for birth certificates, etc. ++ Often this was merely common practice, but sometimes it was set by law. ++ For example, from 1891 to 1911 the UT offset in France was legally ++ 0:09:21 outside train stations and 0:04:21 inside. ++ ++ * Although a named location in the tz database stands for the ++ containing region, its pre-1970 data entries are often accurate for ++ only a small subset of that region. For example, Europe/London ++ stands for the United Kingdom, but its pre-1847 times are valid ++ only for locations that have London's exact meridian, and its 1847 ++ transition to GMT is known to be valid only for the L&NW and the ++ Caledonian railways. ++ ++ * The tz database does not record the earliest time for which a zone's ++ data entries are thereafter valid for every location in the region. ++ For example, Europe/London is valid for all locations in its ++ region after GMT was made the standard time, but the date of ++ standardization (1880-08-02) is not in the tz database, other than ++ in commentary. For many zones the earliest time of validity is ++ unknown. ++ ++ * The tz database does not record a region's boundaries, and in many ++ cases the boundaries are not known. For example, the zone ++ America/Kentucky/Louisville represents a region around the city of ++ Louisville, the boundaries of which are unclear. ++ ++ * Changes that are modeled as instantaneous transitions in the tz ++ database were often spread out over hours, days, or even decades. ++ ++ * Even if the time is specified by law, locations sometimes ++ deliberately flout the law. ++ ++ * Early timekeeping practices, even assuming perfect clocks, were ++ often not specified to the accuracy that the tz database requires. ++ ++ * Sometimes historical timekeeping was specified more precisely ++ than what the tz database can handle. For example, from 1909 to ++ 1937 Netherlands clocks were legally UT +00:19:32.13, but the tz ++ database cannot represent the fractional second. ++ ++ * Even when all the timestamp transitions recorded by the tz database ++ are correct, the tz rules that generate them may not faithfully ++ reflect the historical rules. For example, from 1922 until World ++ War II the UK moved clocks forward the day following the third ++ Saturday in April unless that was Easter, in which case it moved ++ clocks forward the previous Sunday. Because the tz database has no ++ way to specify Easter, these exceptional years are entered as ++ separate tz Rule lines, even though the legal rules did not change. ++ ++ * The tz database models pre-standard time using the proleptic Gregorian ++ calendar and local mean time (LMT), but many people used other ++ calendars and other timescales. For example, the Roman Empire used ++ the Julian calendar, and had 12 varying-length daytime hours with a ++ non-hour-based system at night. ++ ++ * Early clocks were less reliable, and data entries do not represent ++ this unreliability. ++ ++ * As for leap seconds, civil time was not based on atomic time before ++ 1972, and we don't know the history of earth's rotation accurately ++ enough to map SI seconds to historical solar time to more than ++ about one-hour accuracy. See: Morrison LV, Stephenson FR. ++ Historical values of the Earth's clock error Delta T and the ++ calculation of eclipses. J Hist Astron. 2004;35:327-36 ++ <http://adsabs.harvard.edu/full/2004JHA....35..327M>; ++ Historical values of the Earth's clock error. J Hist Astron. 2005;36:339 ++ <http://adsabs.harvard.edu/full/2005JHA....36..339M>. ++ ++ * The relationship between POSIX time (that is, UTC but ignoring leap ++ seconds) and UTC is not agreed upon after 1972. Although the POSIX ++ clock officially stops during an inserted leap second, at least one ++ proposed standard has it jumping back a second instead; and in ++ practice POSIX clocks more typically either progress glacially during ++ a leap second, or are slightly slowed while near a leap second. ++ ++ * The tz database does not represent how uncertain its information is. ++ Ideally it would contain information about when data entries are ++ incomplete or dicey. Partial temporal knowledge is a field of ++ active research, though, and it's not clear how to apply it here. ++ ++In short, many, perhaps most, of the tz database's pre-1970 and future ++time stamps are either wrong or misleading. Any attempt to pass the ++tz database off as the definition of time should be unacceptable to ++anybody who cares about the facts. In particular, the tz database's ++LMT offsets should not be considered meaningful, and should not prompt ++creation of zones merely because two locations differ in LMT or ++transitioned to standard time at different dates. ++ ++ ++----- Time and date functions ----- ++ ++The tz code contains time and date functions that are upwards ++compatible with those of POSIX. ++ ++POSIX has the following properties and limitations. ++ ++* In POSIX, time display in a process is controlled by the ++ environment variable TZ. Unfortunately, the POSIX TZ string takes ++ a form that is hard to describe and is error-prone in practice. ++ Also, POSIX TZ strings can't deal with other (for example, Israeli) ++ daylight saving time rules, or situations where more than two ++ time zone abbreviations are used in an area. ++ ++ The POSIX TZ string takes the following form: ++ ++ stdoffset[dst[offset][,date[/time],date[/time]]] ++ ++ where: ++ ++ std and dst ++ are 3 or more characters specifying the standard ++ and daylight saving time (DST) zone names. ++ Starting with POSIX.1-2001, std and dst may also be ++ in a quoted form like "<UTC+10>"; this allows ++ "+" and "-" in the names. ++ offset ++ is of the form '[+-]hh:[mm[:ss]]' and specifies the ++ offset west of UT. 'hh' may be a single digit; 0<=hh<=24. ++ The default DST offset is one hour ahead of standard time. ++ date[/time],date[/time] ++ specifies the beginning and end of DST. If this is absent, ++ the system supplies its own rules for DST, and these can ++ differ from year to year; typically US DST rules are used. ++ time ++ takes the form 'hh:[mm[:ss]]' and defaults to 02:00. ++ This is the same format as the offset, except that a ++ leading '+' or '-' is not allowed. ++ date ++ takes one of the following forms: ++ Jn (1<=n<=365) ++ origin-1 day number not counting February 29 ++ n (0<=n<=365) ++ origin-0 day number counting February 29 if present ++ Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) ++ for the dth day of week n of month m of the year, ++ where week 1 is the first week in which day d appears, ++ and '5' stands for the last week in which day d appears ++ (which may be either the 4th or 5th week). ++ Typically, this is the only useful form; ++ the n and Jn forms are rarely used. ++ ++ Here is an example POSIX TZ string, for US Pacific time using rules ++ appropriate from 1987 through 2006: ++ ++ TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00' ++ ++ This POSIX TZ string is hard to remember, and mishandles time stamps ++ before 1987 and after 2006. With this package you can use this ++ instead: ++ ++ TZ='America/Los_Angeles' ++ ++* POSIX does not define the exact meaning of TZ values like "EST5EDT". ++ Typically the current US DST rules are used to interpret such values, ++ but this means that the US DST rules are compiled into each program ++ that does time conversion. This means that when US time conversion ++ rules change (as in the United States in 1987), all programs that ++ do time conversion must be recompiled to ensure proper results. ++ ++* The TZ environment variable is process-global, which makes it hard ++ to write efficient, thread-safe applications that need access ++ to multiple time zones. ++ ++* In POSIX, there's no tamper-proof way for a process to learn the ++ system's best idea of local wall clock. (This is important for ++ applications that an administrator wants used only at certain times - ++ without regard to whether the user has fiddled the "TZ" environment ++ variable. While an administrator can "do everything in UTC" to get ++ around the problem, doing so is inconvenient and precludes handling ++ daylight saving time shifts - as might be required to limit phone ++ calls to off-peak hours.) ++ ++* POSIX provides no convenient and efficient way to determine the UT ++ offset and time zone abbreviation of arbitrary time stamps, ++ particularly for time zone settings that do not fit into the ++ POSIX model. ++ ++* POSIX requires that systems ignore leap seconds. ++ ++* The tz code attempts to support all the time_t implementations ++ allowed by POSIX. The time_t type represents a nonnegative count of ++ seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds. ++ In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit ++ signed time_t values stop working after 2038-01-19 03:14:07 UTC, so ++ new implementations these days typically use a signed 64-bit integer. ++ Unsigned 32-bit integers are used on one or two platforms, ++ and 36-bit and 40-bit integers are also used occasionally. ++ Although earlier POSIX versions allowed time_t to be a ++ floating-point type, this was not supported by any practical ++ systems, and POSIX.1-2013 and the tz code both require time_t ++ to be an integer type. ++ ++These are the extensions that have been made to the POSIX functions: ++ ++* The "TZ" environment variable is used in generating the name of a file ++ from which time zone information is read (or is interpreted a la ++ POSIX); "TZ" is no longer constrained to be a three-letter time zone ++ name followed by a number of hours and an optional three-letter ++ daylight time zone name. The daylight saving time rules to be used ++ for a particular time zone are encoded in the time zone file; ++ the format of the file allows U.S., Australian, and other rules to be ++ encoded, and allows for situations where more than two time zone ++ abbreviations are used. ++ ++ It was recognized that allowing the "TZ" environment variable to ++ take on values such as "America/New_York" might cause "old" programs ++ (that expect "TZ" to have a certain form) to operate incorrectly; ++ consideration was given to using some other environment variable ++ (for example, "TIMEZONE") to hold the string used to generate the ++ time zone information file name. In the end, however, it was decided ++ to continue using "TZ": it is widely used for time zone purposes; ++ separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; ++ and systems where "new" forms of "TZ" might cause problems can simply ++ use TZ values such as "EST5EDT" which can be used both by ++ "new" programs (a la POSIX) and "old" programs (as zone names and ++ offsets). ++ ++* The code supports platforms with a UT offset member in struct tm, ++ e.g., tm_gmtoff. ++ ++* The code supports platforms with a time zone abbreviation member in ++ struct tm, e.g., tm_zone. ++ ++* Since the "TZ" environment variable can now be used to control time ++ conversion, the "daylight" and "timezone" variables are no longer ++ needed. (These variables are defined and set by "tzset"; however, their ++ values will not be used by "localtime.") ++ ++* Functions tzalloc, tzfree, localtime_rz, and mktime_z for ++ more-efficient thread-safe applications that need to use ++ multiple time zones. The tzalloc and tzfree functions ++ allocate and free objects of type timezone_t, and localtime_rz ++ and mktime_z are like localtime_r and mktime with an extra ++ timezone_t argument. The functions were inspired by NetBSD. ++ ++* A function "tzsetwall" has been added to arrange for the system's ++ best approximation to local wall clock time to be delivered by ++ subsequent calls to "localtime." Source code for portable ++ applications that "must" run on local wall clock time should call ++ "tzsetwall();" if such code is moved to "old" systems that don't ++ provide tzsetwall, you won't be able to generate an executable program. ++ (These time zone functions also arrange for local wall clock time to be ++ used if tzset is called - directly or indirectly - and there's no "TZ" ++ environment variable; portable applications should not, however, rely ++ on this behavior since it's not the way SVR2 systems behave.) ++ ++* Negative time_t values are supported, on systems where time_t is signed. ++ ++* These functions can account for leap seconds, thanks to Bradley White. ++ ++Points of interest to folks with other systems: ++ ++* Code compatible with this package is already part of many platforms, ++ including GNU/Linux, Android, the BSDs, Chromium OS, Cygwin, AIX, iOS, ++ BlackBery 10, macOS, Microsoft Windows, OpenVMS, and Solaris. ++ On such hosts, the primary use of this package ++ is to update obsolete time zone rule tables. ++ To do this, you may need to compile the time zone compiler ++ 'zic' supplied with this package instead of using the system 'zic', ++ since the format of zic's input is occasionally extended, ++ and a platform may still be shipping an older zic. ++ ++* The UNIX Version 7 "timezone" function is not present in this package; ++ it's impossible to reliably map timezone's arguments (a "minutes west ++ of GMT" value and a "daylight saving time in effect" flag) to a ++ time zone abbreviation, and we refuse to guess. ++ Programs that in the past used the timezone function may now examine ++ tzname[localtime(&clock)->tm_isdst] to learn the correct time ++ zone abbreviation to use. Alternatively, use ++ localtime(&clock)->tm_zone if this has been enabled. ++ ++* The 4.2BSD gettimeofday function is not used in this package. ++ This formerly let users obtain the current UTC offset and DST flag, ++ but this functionality was removed in later versions of BSD. ++ ++* In SVR2, time conversion fails for near-minimum or near-maximum ++ time_t values when doing conversions for places that don't use UT. ++ This package takes care to do these conversions correctly. ++ A comment in the source code tells how to get compatibly wrong ++ results. ++ ++The functions that are conditionally compiled if STD_INSPIRED is defined ++should, at this point, be looked on primarily as food for thought. They are ++not in any sense "standard compatible" - some are not, in fact, specified in ++*any* standard. They do, however, represent responses of various authors to ++standardization proposals. ++ ++Other time conversion proposals, in particular the one developed by folks at ++Hewlett Packard, offer a wider selection of functions that provide capabilities ++beyond those provided here. The absence of such functions from this package ++is not meant to discourage the development, standardization, or use of such ++functions. Rather, their absence reflects the decision to make this package ++contain valid extensions to POSIX, to ensure its broad acceptability. If ++more powerful time conversion functions can be standardized, so much the ++better. ++ ++ ++----- Interface stability ----- ++ ++The tz code and data supply the following interfaces: ++ ++ * A set of zone names as per "Names of time zone rules" above. ++ ++ * Library functions described in "Time and date functions" above. ++ ++ * The programs tzselect, zdump, and zic, documented in their man pages. ++ ++ * The format of zic input files, documented in the zic man page. ++ ++ * The format of zic output files, documented in the tzfile man page. ++ ++ * The format of zone table files, documented in zone1970.tab. ++ ++ * The format of the country code file, documented in iso3166.tab. ++ ++When these interfaces are changed, an effort is made to preserve ++backward compatibility. For example, tz data files typically do not ++rely on recently-added zic features, so that users can run older zic ++versions to process newer data files. ++ ++Interfaces not listed above are less stable. For example, users ++should not rely on particular UT offsets or abbreviations for time ++stamps, as data entries are often based on guesswork and these guesses ++may be corrected or improved. ++ ++ ++----- Calendrical issues ----- ++ ++Calendrical issues are a bit out of scope for a time zone database, ++but they indicate the sort of problems that we would run into if we ++extended the time zone database further into the past. An excellent ++resource in this area is Nachum Dershowitz and Edward M. Reingold, ++Calendrical Calculations: Third Edition, Cambridge University Press (2008) ++<http://emr.cs.iit.edu/home/reingold/calendar-book/third-edition/>. ++Other information and sources are given below. They sometimes disagree. ++ ++ ++France ++ ++Gregorian calendar adopted 1582-12-20. ++French Revolutionary calendar used 1793-11-24 through 1805-12-31, ++and (in Paris only) 1871-05-06 through 1871-05-23. ++ ++ ++Russia ++ ++From Chris Carrier (1996-12-02): ++On 1929-10-01 the Soviet Union instituted an "Eternal Calendar" ++with 30-day months plus 5 holidays, with a 5-day week. ++On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the ++Gregorian calendar while retaining the 6-day week; on 1940-06-27 it ++reverted to the 7-day week. With the 6-day week the usual days ++off were the 6th, 12th, 18th, 24th and 30th of the month. ++(Source: Evitiar Zerubavel, _The Seven Day Circle_) ++ ++ ++Mark Brader reported a similar story in "The Book of Calendars", edited ++by Frank Parise (1982, Facts on File, ISBN 0-8719-6467-8), page 377.

Grotefend, _Taschenbuch der Zeitrechnung des deutschen ++Mittelalters und der Neuzeit_, herausgegeben von Dr. O. Grotefend ++(Hannover: Hahnsche Buchhandlung, 1941), pp. 26-28. ++ ++ ++----- Time and time zones on Mars ----- ++ ++Some people's work schedules use Mars time. Jet Propulsion Laboratory ++(JPL) coordinators have kept Mars time on and off at least since 1997 ++for the Mars Pathfinder mission. Some of their family members have ++also adapted to Mars time. Dozens of special Mars watches were built ++for JPL workers who kept Mars time during the Mars Exploration ++Rovers mission (2004). These timepieces look like normal Seikos and ++Citizens but use Mars seconds rather than terrestrial seconds. ++ ++A Mars solar day is called a "sol" and has a mean period equal to ++about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is ++divided into a conventional 24-hour clock, so each Mars second equals ++about 1.02749125 terrestrial seconds. ++ ++The prime meridian of Mars goes through the center of the crater ++Airy-0, named in honor of the British astronomer who built the ++Greenwich telescope that defines Earth's prime meridian. Mean solar ++time on the Mars prime meridian is called Mars Coordinated Time (MTC). ++ ++Each landed mission on Mars has adopted a different reference for ++solar time keeping, so there is no real standard for Mars time zones. ++For example, the Mars Exploration Rover project (2004) defined two ++time zones "Local Solar Time A" and "Local Solar Time B" for its two ++missions, each zone designed so that its time equals local true solar ++time at approximately the middle of the nominal mission. Such a "time ++zone" is not particularly suited for any application other than the ++mission itself. ++ ++Many calendars have been proposed for Mars, but none have achieved ++wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a ++sequential count of Mars solar days elapsed since about 1873-12-29 ++12:00 GMT. ++ ++The tz database does not currently support Mars time, but it is ++documented here in the hopes that support will be added eventually. ++ ++Sources: ++ ++Michael Allison and Robert Schmunk, ++"Technical Notes on Mars Solar Time as Adopted by the Mars24 Sunclock" ++<http://www.giss.nasa.gov/tools/mars24/help/notes.html> (2012-08-08). ++ ++Jia-Rui Chong, "Workdays Fit for a Martian", Los Angeles Times ++<http://articles.latimes.com/2004/jan/14/science/sci-marstime14> ++(2004-01-14), pp A1, A20-A21. ++ ++Tom Chmielewski, "Jet Lag Is Worse on Mars", The Atlantic (2015-02-26) ++<http://www.theatlantic.com/technology/archive/2015/02/jet-lag-is-worse-on-mars/386033/> ++ ++----- ++ ++This file is in the public domain, so clarified as of 2009-05-17 by ++Arthur David Olson. ++ ++----- ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/africa.orig ++++ contrib/tzdata/africa +@@ -343,6 +343,12 @@ + # decision to abandon DST permanently.

As a result Evenk Autonomous ++# Okrug and Khatangsky district of Taymyr Autonomous Okrug would end ++# up on Moscow+4, Tyumen Oblast on Moscow+2 and the rest on Moscow ++# time. ++# ++# http://astrozet.net/files/Zones/DOC/RU/1980-925.txt ++# attributes the 1982 changes to the Act of the Council of Ministers ++# of the USSR No. 126 from 18.02.1982. 1980-925.txt also adds ++# Udmurtia to the list of affected territories and lists Khatangsky ++# district separately from Taymyr Autonomous Okrug. Probably erroneously. ++# ++# The affected territories are currently listed under Europe/Moscow, ++# Asia/Yekaterinburg and Asia/Krasnoyarsk. ++# ++# 12. Udmurtia ++# The fact that Udmurtia is depicted as a violator in the Nauka i ++# Zhizn article hints at Izhevsk being on different time from ++# Kuybyshev before 1981-10-01. Udmurtia is not mentioned in the 1989 act. ++# http://astrozet.net/files/Zones/DOC/RU/1980-925.txt ++# implies Udmurtia was on Moscow time after 1982-04-01. ++# Wikipedia implies Udmurtia being on Moscow+1 until 1991. ++# ++# ... ++# ++# All Russian zones are supposed to have by default a -1 change at ++# 1991-03-31 2:00 (cancellation of the decree time in the USSR) and a +1 ++# change at 1992-01-19 2:00 (restoration of the decree time in Russia). ++# ++# There were some exceptions, though. ++# Wikipedia says newspapers listed Astrakhan, Saratov, Kirov, Volgograd, ++# Izhevsk, Grozny, Kazan and Samara as such exceptions for the 1992 ++# change. (Different newspapers providing different lists. And some ++# lists found in the internet are quite wild.) ++# ++# And apparently some exceptions were reverted in the last moment. ++# http://www.kaliningradka.ru/site_pc/cherez/index.php?ELEMENT_ID=40091 ++# says that Kaliningrad decided not to be an exception 2 days before the ++# 1991-03-31 switch and one person at ++# http://izhevsk.ru/forum_light_message/50/682597-m8369040.html ++# says he remembers that Samara opted out of the 1992-01-19 exception ++# 2 days before the switch. ++# ++# ++# From Paul Eggert (2016-03-18): ++# Given the above, we appear to be missing some Zone entries for the ++# chaotic early 1980s in Russia.

(Thanks to Alexander Belopolsky ++ for reporting the bug and suggesting a way forward.) ++ ++ If the installed localtime and/or posixrules files are symbolic ++ links, zic now keeps them symbolic links when updating them, for ++ compatibility with platforms like OpenSUSE where other programs ++ configure these files as symlinks. ++ ++ zic now avoids hard linking to symbolic links, avoids some ++ unnecessary mkdir and stat system calls, and uses shorter file ++ names internally. ++ ++ zdump has a new -i option to generate transitions in a ++ more-compact but still human-readable format. This option is ++ experimental, and the output format may change in future versions. ++ (Thanks to Jon Skeet for suggesting that an option was needed, ++ and thanks to Tim Parenti and Chris Rovick for further comments.) ++ ++ Changes to build procedure ++ ++ An experimental distribution format is available, in addition ++ to the traditional format which will continue to be distributed. ++ The new format is a tarball tzdb-VERSION.tar.lz with signature ++ file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory ++ tzdb-VERSION containing the code and data of the traditional ++ two-tarball format, along with extra data that may be useful. ++ (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others ++ for comments about the experimental format.) ++ ++ The release version number is now more accurate in the usual case ++ where releases are built from a Git repository. For example, if ++ 23 commits and some working-file changes have been made since ++ release 2016g, the version number is now something like ++ '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. ++ Official releases uses the same version number format as before, ++ e.g., '2016g'. To support the more-accurate version number, its ++ specification has moved from a line in the Makefile to a new ++ source file 'version'. ++ ++ The experimental distribution contains a file to2050.tzs that ++ contains what should be the output of 'zdump -i -c 2050' on ++ primary zones. If this file is available, 'make check' now checks ++ that zdump generates this output. ++ ++ 'make check_web' now works on Fedora-like distributions. ++ ++ Changes to documentation and commentary ++ ++ tzfile.5 now documents the new restriction on POSIX TZ-like ++ strings that is now implemented by zic. ++ ++ Comments now cite URLs for some 1917-1921 Russian DST decrees. ++ (Thanks to Alexander Belopolsky.) ++ ++ tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J ++ (thanks to Meno Hochschild) and ThreeTen-Extra, and its ++ description of Java 8 has been brought up to date (thanks to ++ Stephen Colebourne).

(Thanks to Christos Zoulas for reporting most of ++ these problems and for suggesting fixes.) ++ ++ If USG_COMPAT is defined and the requested time stamp is standard time, ++ the tz library's localtime and mktime functions now set the extern ++ variable timezone to a value appropriate for that time stamp; and ++ similarly for ALTZONE, daylight saving time, and the altzone variable. ++ This change is a companion to the tzname change in 2014h, and is ++ designed to make timezone and altzone more compatible with tzname. ++ ++ The tz library's functions now set errno to EOVERFLOW if they fail ++ because the result cannot be represented. ctime and ctime_r now ++ return NULL and set errno when a time stamp is out of range, rather ++ than having undefined behavior. ++ ++ Some bugs associated with the new 2014g functions have been fixed. ++ This includes a bug that largely incapacitated the new functions ++ time2posix_z and posix2time_z. (Thanks to Christos Zoulas.) ++ It also includes some uses of uninitialized variables after tzalloc. ++ The new code uses the standard type 'ssize_t', which the Makefile ++ now gives porting advice about. ++ ++ Changes affecting commentary ++ ++ Updated URLs for NRC Canada (thanks to Matt Johnson and Brian Inglis). ++ ++ ++Release 2014h - 2014-09-25 18:59:03 -0700 ++ ++ Changes affecting past time stamps ++ ++ America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28. ++ ++ Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01, ++ not 1920-01-06. The old entry was based on a misinterpretation of Shanks. ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Blantyre, Africa/Bujumbura, ++ Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi, ++ Africa/Lusaka, Africa/Maseru, and Africa/Mbabane. ++ ++ Changes affecting code ++ ++ zdump -V and -v now output gmtoff= values on all platforms, ++ not merely on platforms defining TM_GMTOFF. ++ ++ The tz library's localtime and mktime functions now set tzname to a value ++ appropriate for the requested time stamp, and zdump now uses this ++ on platforms not defining TM_ZONE, fixing a 2014g regression. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ The tz library no longer sets tzname if localtime or mktime fails. ++ ++ zdump -c no longer mishandles transitions near year boundaries. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ An access to uninitialized data has been fixed. ++ (Thanks to Jörg Richter for reporting the problem.) ++ ++ When THREAD_SAFE is defined, the code ports to the C11 memory model. ++ A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined ++ and two threads race to initialize data used by gmtime-like functions. ++ (Thanks to Andy Heninger for reporting the problems.) ++ ++ Changes affecting build procedure ++ ++ 'make check' now checks better for properly-sorted data. ++ ++ Changes affecting documentation and commentary ++ ++ zdump's gmtoff=N output is now documented, and its isdst=D output ++ is now documented to possibly output D values other than 0 or 1. ++ ++ zdump -c's treatment of years is now documented to use the ++ Gregorian calendar and Universal Time without leap seconds, ++ and its behavior at cutoff boundaries is now documented better. ++ (Thanks to Arthur David Olson and Tim Parenti for reporting the problems.) ++ ++ Programs are now documented to use the proleptic Gregorian calendar. ++ (Thanks to Alan Barrett for the suggestion.) ++ ++ Fractional-second GMT offsets have been documented for civil time ++ in 19th-century Chennai, Jakarta, and New York. ++ ++ ++Release 2014g - 2014-08-28 12:31:23 -0700 ++ ++ Changes affecting future time stamps ++ ++ Turks & Caicos is switching from US eastern time to UT -04 ++ year-round, modeled as a switch on 2014-11-02 at 02:00. ++ [As noted in 2014j, this switch was later delayed.] ++ ++ Changes affecting past time stamps ++ ++ Time in Russia or the USSR before 1926 or so has been corrected by ++ a few seconds in the following zones: Asia/Irkutsk, ++ Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi, ++ Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For ++ Asia/Yekaterinburg the correction is a few minutes. (Thanks to ++ Vladimir Karpinsky.) ++ ++ The Portuguese decree of 1911-05-26 took effect on 1912-01-01. ++ This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, ++ Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912 ++ GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. ++ (Thanks to Stephen Colebourne for pointing to the decree.) ++ ++ Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59. ++ ++ A new file 'backzone' contains data which may appeal to ++ connoisseurs of old time stamps, although it is out of scope for ++ the tz database, is often poorly sourced, and contains some data ++ that is known to be incorrect. The new file is not recommended ++ for ordinary use and its entries are not installed by default. ++ (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and ++ Isle of Man entries.) ++ ++ Some more zones have been turned into links, when they differed ++ from existing zones only for older time stamps. As usual, ++ these changes affect UTC offsets in pre-1970 time stamps only. ++ Their old contents have been moved to the 'backzone' file. ++ The affected zones are: Africa/Bangui, Africa/Brazzaville, ++ Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, ++ Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. ++ ++ Changes affecting code ++ ++ Unless NETBSD_INSPIRED is defined to 0, the tz library now ++ supplies functions for creating and using objects that represent ++ time zones. The new functions are tzalloc, tzfree, localtime_rz, ++ mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and ++ time2posix_z. They are intended for performance: for example, ++ localtime_rz (unlike localtime_r) is trivially thread-safe without ++ locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired ++ functions, and to Alan Barrett and Jonathan Lennox for helping to ++ debug the change.) ++ ++ zdump now builds with the tz library unless USE_LTZ is defined to 0, ++ This lets zdump use tz features even if the system library lacks them. ++ To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 ++ TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. ++ ++ zdump now uses localtime_rz if available, as it's significantly faster, ++ and it can help zdump better diagnose invalid time zone names. ++ Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ ++ defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is ++ not available, zdump now uses localtime_r and tzset if available, ++ as this is a bit cleaner and faster than plain localtime. Compile ++ with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system ++ lacks these two functions. ++ ++ If THREAD_SAFE is defined to 1, the tz library is now thread-safe. ++ Although not needed for tz's own applications, which are single-threaded, ++ this supports POSIX better if the tz library is used in multithreaded apps. ++ ++ Some crashes have been fixed when zdump or the tz library is given ++ invalid or outlandish input. ++ ++ The tz library no longer mishandles leap seconds on platforms with ++ unsigned time_t in time zones that lack ordinary transitions after 1970. ++ ++ The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not ++ already defined, to make it easier to configure on common platforms. ++ Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. ++ ++ Unless the new macro UNINIT_TRAP is defined to 1, the tz code now ++ assumes that reading uninitialized memory yields garbage values ++ but does not cause other problems such as traps. ++ ++ If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now ++ more likely to guess right for ambiguous time stamps near ++ transitions where tm_isdst does not change. ++ ++ If HAVE_STRFTIME_L is defined to 1, the tz library now defines ++ strftime_l for compatibility with recent versions of POSIX. ++ Only the C locale is supported, though. HAVE_STRFTIME_L defaults ++ to 1 on recent POSIX versions, and to 0 otherwise. ++ ++ tzselect -c now uses a hybrid distance measure that works better ++ in Africa. (Thanks to Alan Barrett for noting the problem.) ++ ++ The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, ++ or when time_tz is defined. ++ ++ When HAVE_UTMPX_H is set the 'date' command now builds on systems ++ whose <utmpx.h> file does not define WTMPX_FILE, and when setting ++ the date it updates the wtmpx file if _PATH_WTMPX is defined. ++ This affects GNU/Linux and similar systems. ++ ++ For easier maintenance later, some C code has been simplified, ++ some lint has been removed, and the code has been tweaked so that ++ plain 'make' is more likely to work. ++ ++ The C type 'bool' is now used for boolean values, instead of 'int'. ++ ++ The long-obsolete LOCALE_HOME code has been removed. ++ ++ The long-obsolete 'gtime' function has been removed. ++ ++ Changes affecting build procedure ++ ++ 'zdump' no longer links in ialloc.o, as it's not needed. ++ ++ 'make check_time_t_alternatives' no longer assumes GNU diff. ++ ++ Changes affecting distribution tarballs ++ ++ The files checktab.awk and zoneinfo2tdf.pl are now distributed in ++ the tzdata tarball instead of the tzcode tarball, since they help ++ maintain the data. The NEWS and Theory files are now also ++ distributed in the tzdata tarball, as they're relevant for data. ++ (Thanks to Alan Barrett for pointing this out.) Also, the ++ leapseconds.awk file is no longer distributed in the tzcode ++ tarball, since it belongs in the tzdata tarball (where 2014f ++ inadvertently also distributed it). ++ ++ Changes affecting documentation and commentary ++ ++ A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for ++ suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms ++ for debugging it.) ++ ++ The man pages have been updated to use function prototypes, ++ to document thread-safe variants like localtime_r, and to document ++ the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and ++ mktime_z. ++ ++ The fields in Link lines have been renamed to be more descriptive ++ and more like the parameters of 'ln'. LINK-FROM has become TARGET, ++ and LINK-TO has become LINK-NAME. ++ ++ tz-link.htm mentions the IETF's tzdist working group; Windows ++ Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. ++ ++ Some broken URLs have been fixed in the commentary. (Thanks to ++ Lester Caine.) ++ ++ Commentary about Philippines DST has been updated, and commentary ++ on pre-1970 time in India has been added. ++ ++ ++Release 2014f - 2014-08-05 17:42:36 -0700 ++ ++ Changes affecting future time stamps ++ ++ Russia will subtract an hour from most of its time zones on 2014-10-26 ++ at 02:00 local time. (Thanks to Alexander Krivenyshev.) ++ There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky ++ Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug ++ (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast ++ (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic ++ (Europe/Samara) are not changing their clocks. The changed zones are ++ Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, ++ Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, ++ Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, ++ Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours ++ subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, ++ but not its UTC offset. Two zones are added: Asia/Chita (split ++ from Asia/Yakutsk, and also with two hours subtracted) and ++ Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour ++ subtracted). (Thanks to Tim Parenti for much of the above.) ++ ++ Changes affecting time zone abbreviations ++ ++ Australian eastern time zone abbreviations are now AEST/AEDT not EST, ++ and similarly for the other Australian zones. That is, for eastern ++ standard and daylight saving time the abbreviations are AEST and AEDT ++ instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT, ++ and AWST/AWDT are now used instead of the former CST, CWST, and WST. ++ This change does not affect UTC offsets, only time zone abbreviations. ++ (Thanks to Rich Tibbett and many others.) ++ ++ Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UT +07) ++ effective 2014-10-26 at 02:00 local time. ++ ++ The time zone abbreviation for Xinjiang Time (observed in Ürümqi) ++ has been changed from URUT to XJT. (Thanks to Luther Ma.) ++ ++ Prefer MSK/MSD for Moscow time in Russia, even in other cities. ++ Similarly, prefer EET/EEST for eastern European time in Russia. ++ ++ Change time zone abbreviations in (western) Samoa to use "ST" and ++ "DT" suffixes, as this is more likely to match common practice. ++ Prefix "W" to (western) Samoa time when its standard-time offset ++ disagrees with that of American Samoa. ++ ++ America/Metlakatla now uses PST, not MeST, to abbreviate its time zone. ++ ++ Time zone abbreviations have been updated for Japan's two time ++ zones used 1896-1937. JWST now stands for Western Standard ++ Time, and JCST for Central Standard Time (formerly this was CJT). ++ These abbreviations are now used for time in Korea, Taiwan, ++ and Sakhalin while controlled by Japan. ++ ++ Changes affecting past time stamps ++ ++ China's five zones have been simplified to two, since the post-1970 ++ differences in the other three seem to have been imaginary. The ++ zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been ++ removed; backwards-compatibility links still work, albeit with ++ different behaviors for time stamps before May 1980. Asia/Urumqi's ++ 1980 transition to UT +08 has been removed, so that it is now at ++ +06 and not +08. (Thanks to Luther Ma and to Alois Treindl; ++ Treindl sent helpful translations of two papers by Guo Qingsheng.) ++ ++ Some zones have been turned into links, when they differed from existing ++ zones only for older UTC offsets where data entries were likely invented. ++ These changes affect UTC offsets in pre-1970 time stamps only. This is ++ similar to the change in release 2013e, except this time for western ++ Africa. The affected zones are: Africa/Bamako, Africa/Banjul, ++ Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, ++ Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and ++ Atlantic/St_Helena. This also affects the backwards-compatibility ++ link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, ++ Tim Parenti, and David Patte for reporting problems in earlier ++ versions of this change.) ++ ++ Asia/Shanghai's pre-standard-time UT offset has been changed from ++ 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its ++ transition to standard time has been changed from 1928 to 1901. ++ ++ Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, ++ then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. ++ In 1946 it observed DST from 05-15 through 09-30; in 1947 ++ from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. ++ (Thanks to Yu-Cheng Chuang.) ++ ++ Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. ++ ++ Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not ++ 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) ++ ++ Pacific/Pago_Pago has been changed from UT -11:30 to -11 for the ++ period from 1911 to 1950. ++ ++ Pacific/Chatham has been changed to New Zealand standard time plus ++ 45 minutes for the period before 1957, reflecting a 1956 remark in ++ the New Zealand parliament. ++ ++ Europe/Budapest has several pre-1946 corrections: in 1918 the transition ++ out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in ++ 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 ++ not 04-06 at 02:00; and there was no DST in 1920. ++ ++ Africa/Accra is now assumed to have observed DST from 1920 through 1935. ++ ++ Time in Russia before 1927 or so has been corrected by a few seconds in ++ the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, ++ Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and ++ Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 ++ point. (Thanks to Vladimir Karpinsky for the Moscow changes.) ++ ++ Changes affecting data format ++ ++ A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. ++ The new file's extended format allows multiple country codes per zone. ++ The older file is still installed but is deprecated; its format is ++ not changing and it will still be distributed for a while, but new ++ applications should use the new file. ++ ++ The new file format simplifies maintenance of obscure locations. ++ To test this, it adds coverage for the Crozet Islands and the ++ Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) ++ ++ The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. ++ It is still ASCII now, but commentary about the switch has been added. ++ The new file 'zone1970.tab' already uses UTF-8. ++ ++ Changes affecting code ++ ++ 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE ++ is defined. (Thanks to Elliott Hughes for reporting the problem.) ++ ++ 'zic' no longer mishandles input when ignoring case in locales that ++ are not compatible with English, e.g., unibyte Turkish locales when ++ compiled with HAVE_GETTEXT. ++ ++ Error diagnostics of 'zic' and 'yearistype' have been reworded so that ++ they no longer use ASCII '-' as if it were a dash. ++ ++ 'zic' now rejects output file names that contain '.' or '..' components. ++ (Thanks to Tim Parenti for reporting the problem.) ++ ++ 'zic -v' now warns about output file names that do not follow ++ POSIX rules, or that contain a digit or '.'. (Thanks to Arthur ++ David Olson for starting the ball rolling on this.) ++ ++ Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. ++ ++ Changes affecting build procedure ++ ++ 'zic' no longer links in localtime.o and asctime.o, as they're not needed. ++ (Thanks to John Cochran.) ++ ++ Changes affecting documentation and commentary ++ ++ The 'Theory' file documents legacy names, the longstanding ++ exceptions to the POSIX-inspired file name rules. ++ ++ The 'zic' documentation clarifies the role of time types when ++ interpreting dates. (Thanks to Arthur David Olson.) ++ ++ Documentation and commentary now prefer UTF-8 to US-ASCII, ++ allowing the use of proper accents in foreign words and names. ++ Code and data have not changed because of this. (Thanks to ++ Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug ++ this.) ++ ++ Non-HTML documentation and commentary now use plain-text URLs instead of ++ HTML insertions, and are more consistent about bracketing URLs when they ++ are not already surrounded by white space. (Thanks to suggestions by ++ Steffen Nurpmeso.) ++ ++ There is new commentary about Xujiahui Observatory, the five time-zone ++ project in China from 1918 to 1949, timekeeping in Japanese-occupied ++ Shanghai, and Tibet Time in the 1950s. The sharp-eyed can spot the ++ warlord Jin Shuren in the data. ++ ++ Commentary about the coverage of each Russian zone has been standardized. ++ (Thanks to Tim Parenti). ++ ++ There is new commentary about contemporary timekeeping in Ethiopia. ++ ++ Obsolete comments about a 2007 proposal for DST in Kuwait has been removed. ++ ++ There is new commentary about time in Poland in 1919. ++ ++ Proper credit has been given to DST inventor George Vernon Hudson. ++ ++ Commentary about time in Metlakatla, AK and Resolute, NU has been ++ improved, with a new source for the former. ++ ++ In zone.tab, Pacific/Easter no longer mentions Salas y Gómez, as it ++ is uninhabited. ++ ++ Commentary about permanent Antarctic bases has been updated. ++ ++ Several typos have been corrected. (Thanks to Tim Parenti for ++ contributing some of these fixes.) ++ ++ tz-link.htm now mentions the JavaScript libraries Moment Timezone, ++ TimezoneJS.Date, Walltime-js, and Timezone. (Thanks to a heads-up ++ from Matt Johnson.) Also, it mentions the Go 'latlong' package. ++ (Thanks to a heads-up from Dirkjan Ochtman.) ++ ++ The files usno1988, usno1989, usno1989a, usno1995, usno1997, and usno1998 ++ have been removed. These obsolescent US Naval Observatory entries were no ++ longer helpful for maintenance. (Thanks to Tim Parenti for the suggestion.) ++ ++ ++Release 2014e - 2014-06-12 21:53:52 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00. ++ (Thanks to Imed Chihi.)

Guess that from 2015 on Morocco will ++ temporarily switch to standard time at 03:00 the last Saturday before ++ Ramadan, and back to DST at 02:00 the first Saturday after Ramadan. ++ ++ Changes affecting past time stamps ++ ++ The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of ++ "MSD" for Moscow's double daylight time in summer 1921. Also, a typo ++ "VLASST" has been repaired to be "VLAST" for Vladivostok summer time ++ in 1991. (Thanks to Hank W. for reporting the problems.) ++ ++ Changes affecting commentary ++ ++ tz-link.htm now cites RFC 7265 for jCal, mentions PTP and the ++ draft CalDAV extension, updates URLs for TSP, TZInfo, IATA, and ++ removes stale pointers to World Time Explorer and WORLDTIME. ++ ++ ++Release 2014d - 2014-05-27 21:34:40 -0700 ++ ++ Changes affecting code ++ ++ zic no longer generates files containing time stamps before the Big Bang. ++ This works around GNOME bug 730332 ++ <https://bugzilla.gnome.org/show_bug.cgi?id=730332>. ++ (Thanks to Leonardo Chiquitto for reporting the bug, and to ++ Arthur David Olson and James Cloos for suggesting improvements to the fix.) ++ ++ Changes affecting documentation ++ ++ tz-link.htm now mentions GNOME. ++ ++ ++Release 2014c - 2014-05-13 07:44:13 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Egypt observes DST starting 2014-05-15 at 24:00. ++ (Thanks to Ahmad El-Dardiry and Gunther Vermier.) ++ Details have not been announced, except that DST will not be observed ++ during Ramadan.

(Thanks to Michael Forney.) ++ ++ A dependency typo in the 'zdump' rule has been fixed. ++ (Thanks to Andrew Paprocki.) ++ ++ The Makefile has been simplified by assuming that 'mkdir -p' and 'cp -f' ++ work as specified by POSIX.2-1992 or later; this is portable nowadays. ++ ++ 'make clean' no longer removes 'leapseconds', since it's ++ host-independent and is part of the distribution. ++ ++ The unused makefile macros TZCSRCS, TZDSRCS, DATESRCS have been removed. ++ ++ Changes affecting documentation and commentary ++ ++ tz-link.htm now mentions TC TIMEZONE's draft time zone service protocol ++ (thanks to Mike Douglass) and TimezoneJS.Date (thanks to Jim Fehrle). ++ ++ Update URLs in tz-link page. Add URLs for Microsoft Windows, since ++ 8.1 introduces tz support. Remove URLs for Tru64 and UnixWare (no ++ longer maintained) and for old advisories. SOFA now does C. ++ ++Release 2013g - 2013-09-30 21:08:26 -0700 ++ ++ Changes affecting current and near-future time stamps ++ ++ Morocco now observes DST from the last Sunday in March to the last ++ Sunday in October, not April to September respectively. (Thanks ++ to Steffen Thorsen.) ++ ++ Changes affecting 'zic' ++ ++ 'zic' now runs on platforms that lack both hard links and symlinks. ++ (Thanks to Theo Veenker for reporting the problem, for MinGW.) ++ Also, fix some bugs on platforms that lack hard links but have symlinks. ++ ++ 'zic -v' again warns that Asia/Tehran has no POSIX environment variable ++ to predict the far future, fixing a bug introduced in 2013e. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is again put into the tzdata tarball. ++ Also, 'leapseconds.awk', so tzdata is self-contained. (Thanks to ++ Matt Burgess and Ian Abbott.) The timestamps of these and other ++ dependent files in tarballs are adjusted more consistently. ++ ++ Changes affecting documentation and commentary ++ ++ The README file is now part of the data tarball as well as the code. ++ It now states that files are public domain unless otherwise specified. ++ (Thanks to Andrew Main (Zefram) for asking for clarifications.) ++ Its details about the 1989 release moved to a place of honor near ++ the end of NEWS. ++ ++ ++Release 2013f - 2013-09-24 23:37:36 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ Tocantins will very likely not observe DST starting this spring. ++ (Thanks to Steffen Thorsen.) ++ ++ Jordan will likely stay at UT +03 indefinitely, and will not fall ++ back this fall. ++ ++ Palestine will fall back at 00:00, not 01:00. (Thanks to Steffen Thorsen.) ++ ++ Changes affecting API ++ ++ The types of the global variables 'timezone' and 'altzone' (if present) ++ have been changed back to 'long'. This is required for 'timezone' ++ by POSIX, and for 'altzone' by common practice, e.g., Solaris 11. ++ These variables were originally 'long' in the tz code, but were ++ mistakenly changed to 'time_t' in 1987; nobody reported the ++ incompatibility until now. The difference matters on x32, where ++ 'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.) ++ ++ Changes affecting the build procedure ++ ++ Avoid long strings in leapseconds.awk to work around a mawk bug. ++ (Thanks to Cyril Baurand.) ++ ++ Changes affecting documentation and commentary ++ ++ New file 'NEWS' that contains release notes like this one. ++ ++ Paraguay's law does not specify DST transition time; 00:00 is customary. ++ (Thanks to Waldemar Villamayor-Venialbo.) ++ ++ Minor capitalization fixes. ++ ++ Changes affecting version-control only ++ ++ The experimental GitHub repository now contains annotated and ++ signed tags for recent releases, e.g., '2013e' for Release 2013e. ++ Releases are tagged starting with 2012e; earlier releases were ++ done differently, and tags would either not have a simple name or ++ not exactly match what was released. ++ ++ 'make set-timestamps' is now simpler and a bit more portable. ++ ++ ++Release 2013e - 2013-09-19 23:50:04 -0700 ++ ++ Changes affecting near-future time stamps ++ ++ This year Fiji will start DST on October 27, not October 20. ++ (Thanks to David Wheeler for the heads-up.) For now, guess that ++ Fiji will continue to spring forward the Sunday before the fourth ++ Monday in October. ++ ++ Changes affecting current and future time zone abbreviations ++ ++ Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian ++ time zone abbreviations since 1932. (Thanks to George Ziegler, ++ Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and ++ Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, ++ Asia/Makassar, and Asia/Pontianak. ++ ++ Use ART (UT -03, standard time), rather than WARST (also -03, but ++ daylight saving time) for San Luis, Argentina since 2009. ++ ++ Changes affecting Godthåb time stamps after 2037 if version mismatch ++ ++ Allow POSIX-like TZ strings where the transition time's hour can ++ range from -167 through 167, instead of the POSIX-required 0 ++ through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the ++ new Fiji rules. This is a more-compact way to represent ++ far-future time stamps for America/Godthab, America/Santiago, ++ Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, ++ Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by ++ this change. (Derived from a suggestion by Arthur David Olson.) ++ ++ Allow POSIX-like TZ strings where daylight saving time is in ++ effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western ++ Argentina Summer Time all year. This supports a more-compact way ++ to represent the 2013d data for America/Argentina/San_Luis. ++ Because of the change for San Luis noted above this change does not ++ affect the current data. (Thanks to Andrew Main (Zefram) for ++ suggestions that improved this change.) ++ ++ Where these two TZ changes take effect, there is a minor extension ++ to the tz file format in that it allows new values for the ++ embedded TZ-format string, and the tz file format version number ++ has therefore been increased from 2 to 3 as a precaution. ++ Version-2-based client code should continue to work as before for ++ all time stamps before 2038. Existing version-2-based client code ++ (tzcode, GNU/Linux, Solaris) has been tested on version-3-format ++ files, and typically works in practice even for time stamps after ++ 2037; the only known exception is America/Godthab. ++ ++ Changes affecting time stamps before 1970 ++ ++ Pacific/Johnston is now a link to Pacific/Honolulu. This corrects ++ some errors before 1947. ++ ++ Some zones have been turned into links, when they differ from existing ++ zones only in older data entries that were likely invented or that ++ differ only in LMT or transitions from LMT. These changes affect ++ only time stamps before 1943. The affected zones are: ++ Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, ++ America/Grenada, America/Guadeloupe, America/Marigot, ++ America/Montserrat, America/St_Barthelemy, America/St_Kitts, ++ America/St_Lucia, America/St_Thomas, America/St_Vincent, ++ America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for ++ confirming that the old Europe/Vaduz zone was wrong and the new ++ link is better for WWII-era times.) ++ ++ Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects ++ America/Cayman, America/Jamaica and America/Grand_Turk time stamps ++ from 1890 to 1912. ++ ++ Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. ++ This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks ++ to Alois Treindl). ++ ++ Change the date of the circa-1850 Zurich transition from 1849-09-12 ++ to 1853-07-16, overriding Shanks with data from Messerli about ++ postal and telegraph time in Switzerland. ++ ++ Changes affecting time zone abbreviations before 1970 ++ ++ For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, ++ as Jakarta was called Batavia back then. ++ ++ Changes affecting API ++ ++ The 'zic' command now outputs a dummy transition when far-future ++ data can't be summarized using a TZ string, and uses a 402-year ++ window rather than a 400-year window. For the current data, this ++ affects only the Asia/Tehran file. It does not affect any of the ++ time stamps that this file represents, so zdump outputs the same ++ information as before. (Thanks to Andrew Main (Zefram).) ++ ++ The 'date' command has a new '-r' option, which lets you specify ++ the integer time to display, a la FreeBSD. ++ ++ The 'tzselect' command has two new options '-c' and '-n', which lets you ++ select a zone based on latitude and longitude. ++ ++ The 'zic' command's '-v' option now warns about constructs that ++ require the new version-3 binary file format. (Thanks to Arthur ++ David Olson for the suggestion.) ++ ++ Support for floating-point time_t has been removed. ++ It was always dicey, and POSIX no longer requires it. ++ (Thanks to Eric Blake for suggesting to the POSIX committee to ++ remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy ++ Heninger, Arthur David Olson, and Alois Treindl, for reporting ++ bugs and elucidating some of the corners of the old floating-point ++ implementation.) ++ ++ The signatures of 'offtime', 'timeoff', and 'gtime' have been ++ changed back to the old practice of using 'long' to represent UT ++ offsets. This had been inadvertently and mistakenly changed to ++ 'int_fast32_t'. (Thanks to Christos Zoulas.) ++ ++ The code avoids undefined behavior on integer overflow in some ++ more places, including gmtime, localtime, mktime and zdump. ++ ++ Changes affecting the zdump utility ++ ++ zdump now outputs "UT" when referring to Universal Time, not "UTC". ++ "UTC" does not make sense for time stamps that predate the introduction ++ of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen ++ for clarifying UT vs UTC.) ++ ++ Data changes affecting behavior of tzselect and similar programs ++ ++ Country code BQ is now called the more-common name "Caribbean Netherlands" ++ rather than the more-official "Bonaire, St Eustatius & Saba". ++ ++ Remove from zone.tab the names America/Montreal, America/Shiprock, ++ and Antarctica/South_Pole, as they are equivalent to existing ++ same-country-code zones for post-1970 time stamps. The data entries for ++ these names are unchanged, so the names continue to work as before. ++ ++ Changes affecting code internals ++ ++ zic -c now runs way faster on 64-bit hosts when given large numbers. ++ ++ zic now uses vfprintf to avoid allocating and freeing some memory. ++ ++ tzselect now computes the list of continents from the data, ++ rather than have it hard-coded. ++ ++ Minor changes pacify GCC 4.7.3 and GCC 4.8.1. ++ ++ Changes affecting the build procedure ++ ++ The 'leapseconds' file is now generated automatically from a ++ new file 'leap-seconds.list', which is a copy of ++ <ftp://time.nist.gov/pub/leap-seconds.list>. ++ A new source file 'leapseconds.awk' implements this. ++ The goal is simplification of the future maintenance of 'leapseconds'. ++ ++ When building the 'posix' or 'right' subdirectories, if the ++ subdirectory would be a copy of the default subdirectory, it is ++ now made a symbolic link if that is supported. This saves about ++ 2 MB of file system space. ++ ++ The links America/Shiprock and Antarctica/South_Pole have been ++ moved to the 'backward' file. This affects only nondefault builds ++ that omit 'backward'. ++ ++ Changes affecting version-control only ++ ++ .gitignore now ignores 'date'. ++ ++ Changes affecting documentation and commentary ++ ++ Changes to the 'tzfile' man page ++ ++ It now mentions that the binary file format may be extended in ++ future versions by appending data. ++ ++ It now refers to the 'zdump' and 'zic' man pages. ++ ++ Changes to the 'zic' man page ++ ++ It lists conditions that elicit a warning with '-v'. ++ ++ It says that the behavior is unspecified when duplicate names ++ are given, or if the source of one link is the target of another. ++ ++ Its examples are updated to match the latest data. ++ ++ The definition of white space has been clarified slightly. ++ (Thanks to Michael Deckers.) ++ ++ Changes to the 'Theory' file ++ ++ There is a new section about the accuracy of the tz database, ++ describing the many ways that errors can creep in, and ++ explaining why so many of the pre-1970 time stamps are wrong or ++ misleading (thanks to Steve Allen, Lester Caine, and Garrett ++ Wollman for discussions that contributed to this). ++ ++ The 'Theory' file describes LMT better (this follows a ++ suggestion by Guy Harris). ++ ++ It refers to the 2013 edition of POSIX rather than the 2004 edition. ++ ++ It's mentioned that excluding 'backward' should not affect the ++ other data, and it suggests at least one zone.tab name per ++ inhabited country (thanks to Stephen Colebourne). ++ ++ Some longstanding restrictions on names are documented, e.g., ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ ++ It gives more reasons for the 1970 cutoff. ++ ++ It now mentions which time_t variants are supported, such as ++ signed integer time_t. (Thanks to Paul Goyette for reporting ++ typos in an experimental version of this change.) ++ ++ (Thanks to Philip Newton for correcting typos in these changes.) ++ ++ Documentation and commentary is more careful to distinguish UT in ++ general from UTC in particular. (Thanks to Steve Allen.) ++ ++ Add a better source for the Zurich 1894 transition. ++ (Thanks to Pierre-Yves Berger.) ++ ++ Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.) ++ ++ ++Release 2013d - 2013-07-05 07:38:01 -0700 ++ ++ Changes affecting future time stamps: ++ ++ Morocco's midsummer transitions this year are July 7 and August 10, ++ not July 9 and August 8. (Thanks to Andrew Paprocki.) ++ ++ Israel now falls back on the last Sunday of October. ++ (Thanks to Ephraim Silverberg.) ++ ++ Changes affecting past time stamps: ++ ++ Specify Jerusalem's location more precisely; this changes the pre-1880 ++ times by 2 s. ++ ++ Changing affecting metadata only: ++ ++ Fix typos in the entries for country codes BQ and SX. ++ ++ Changes affecting code: ++ ++ Rework the code to fix a bug with handling Australia/Macquarie on ++ 32-bit hosts (thanks to Arthur David Olson). ++ ++ Port to platforms like NetBSD, where time_t can be wider than long. ++ ++ Add support for testing time_t types other than the system's. ++ Run 'make check_time_t_alternatives' to try this out. ++ Currently, the tests fail for unsigned time_t; ++ this should get fixed at some point. ++ ++ Changes affecting documentation and commentary: ++ ++ Deemphasize the significance of national borders. ++ ++ Update the zdump man page. ++ ++ Remove obsolete NOID comment (thanks to Denis Excoffier). ++ ++ Update several URLs and comments in the web pages. ++ ++ Spelling fixes (thanks to Kevin Lyda and Jonathan Leffler). ++ ++ Update URL for CLDR Zone->Tzid table (thanks to Yoshito Umaoka). ++ ++ ++Release 2013c - 2013-04-19 16:17:40 -0700 ++ ++ Changes affecting current and future time stamps: ++ ++ Palestine observed DST starting March 29, 2013.

Second, the Pridnestrovian Moldavian Republic ++ (Europe/Tiraspol) decided not to split from the rest of Moldova after ++ all, and consequently that zone has been removed (again) and reinstated ++ in the "backward" file as a link to Europe/Chisinau. And third, the ++ end date for Fiji's summer time this summer was moved forward from the ++ earlier planned Feb 26, to Jan 22. ++ ++ Apart from that, Moldova (MD) returns to a single entry in zone.tab ++ (and the incorrect syntax that was in the 2011m version of that file ++ is so fixed - it would have been fixed in a different way had this ++ change not happened - that's the "missing" sccs version id). ++ ++ ++Release data2011m - 2011-10-24 21:42:16 +0700 ++ ++ In particular, the typos in comments in the data (2011-11-17 should have ++ been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that ++ Tim Parenti noted) have been fixed, and the change for Ukraine has been ++ made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to ++ Tim Parenti, and also Denys Gavrysh) ++ ++ In addition, I added Europe/Tiraspol to zone.tab. ++ ++ This time, all the files have new version numbers...

The text has been ++adapted and reformatted for the purposes of this file. ++ ++Traditionally a release R consists of a pair of tarball files, ++tzcodeR.tar.gz and tzdataR.tar.gz. However, some releases (e.g., ++code2010a, data2012c) consist of just one or the other tarball, and a ++few (e.g., code2012c-data2012d) have tarballs with mixed version ++numbers. Recent releases also come in an experimental format ++consisting of a single tarball tzdb-R.tar.lz with extra data. ++ ++Release time stamps are taken from the release's commit (for newer, ++Git-based releases), from the newest file in the tarball (for older ++releases, where this info is available) or from the email announcing ++the release (if all else fails; these are marked with a time zone of ++-0000 and an "is missing!" comment). ++ ++Earlier versions of the code and data were not announced on the tz ++list and are not summarized here. ++ ++This file is in the public domain. ++ ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/README.orig ++++ contrib/tzdata/README +@@ -0,0 +1,71 @@ ++README for the tz distribution ++ ++"What time is it?" -- Richard Deacon as The King ++"Any time you want it to be." -- Frank Baxter as The Scientist ++ (from the Bell System film "About Time") ++ ++The Time Zone Database (often called tz or zoneinfo) contains code and ++data that represent the history of local time for many representative ++locations around the globe.

To represent this ++data, the world is partitioned into regions whose clocks all agree ++about time stamps that occur after the somewhat-arbitrary cutoff point ++of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region, ++the database records all known clock transitions, and labels the region ++with a notable location. Although 1970 is a somewhat-arbitrary ++cutoff, there are significant challenges to moving the cutoff earlier ++even by a decade or two, due to the wide variety of local practices ++before computer timekeeping became prevalent. ++ ++Clock transitions before 1970 are recorded for each such location, ++because most systems support time stamps before 1970 and could ++misbehave if data entries were omitted for pre-1970 transitions. ++However, the database is not designed for and does not suffice for ++applications requiring accurate handling of all past times everywhere, ++as it would take far too much effort and guesswork to record all ++details of pre-1970 civil timekeeping. ++ ++As described below, reference source code for using the tz database is ++also available. The tz code is upwards compatible with POSIX, an ++international standard for UNIX-like systems. As of this writing, the ++current edition of POSIX is: ++ ++ The Open Group Base Specifications Issue 7 ++ IEEE Std 1003.1, 2013 Edition ++ <http://pubs.opengroup.org/onlinepubs/9699919799/> ++ ++ ++ ++----- Names of time zone rules ----- ++ ++Each of the database's time zone rules has a unique name. ++Inexperienced users are not expected to select these names unaided. ++Distributors should provide documentation and/or a simple selection ++interface that explains the names; for one example, see the 'tzselect' ++program in the tz code. The Unicode Common Locale Data Repository ++<http://cldr.unicode.org/> contains data that may be useful for other ++selection interfaces. ++ ++The time zone rule naming conventions attempt to strike a balance ++among the following goals: ++ ++ * Uniquely identify every region where clocks have agreed since 1970. ++ This is essential for the intended use: static clocks keeping local ++ civil time. ++ ++ * Indicate to experts where that region is. ++ ++ * Be robust in the presence of political changes. For example, names ++ of countries are ordinarily not used, to avoid incompatibilities ++ when countries change their name (e.g. Zaire->Congo) or when ++ locations change countries (e.g. Hong Kong from UK colony to ++ China). ++ ++ * Be portable to a wide variety of implementations. ++ ++ * Use a consistent naming conventions over the entire world. ++ ++Names normally have the form AREA/LOCATION, where AREA is the name ++of a continent or ocean, and LOCATION is the name of a specific ++location within that region. North and South America share the same ++area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York', ++and 'Pacific/Honolulu'. ++ ++Here are the general rules used for choosing location names, ++in decreasing order of importance: ++ ++ Use only valid POSIX file name components (i.e., the parts of ++ names other than '/'). Do not use the file name ++ components '.' and '..'. Within a file name component, ++ use only ASCII letters, '.', '-' and '_'. Do not use ++ digits, as that might create an ambiguity with POSIX ++ TZ strings. A file name component must not exceed 14 ++ characters or start with '-'. E.g., prefer 'Brunei' ++ to 'Bandar_Seri_Begawan'. Exceptions: see the discussion ++ of legacy names below. ++ A name must not be empty, or contain '//', or start or end with '/'. ++ Do not use names that differ only in case. Although the reference ++ implementation is case-sensitive, some other implementations ++ are not, and they would mishandle names differing only in case. ++ If one name A is an initial prefix of another name AB (ignoring case), ++ then B must not start with '/', as a regular file cannot have ++ the same name as a directory in POSIX. For example, ++ 'America/New_York' precludes 'America/New_York/Bronx'. ++ Uninhabited regions like the North Pole and Bouvet Island ++ do not need locations, since local time is not defined there. ++ There should typically be at least one name for each ISO 3166-1 ++ officially assigned two-letter code for an inhabited country ++ or territory. ++ If all the clocks in a region have agreed since 1970, ++ don't bother to include more than one location ++ even if subregions' clocks disagreed before 1970. ++ Otherwise these tables would become annoyingly large. ++ If a name is ambiguous, use a less ambiguous alternative; ++ e.g. many cities are named San José and Georgetown, so ++ prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'. ++ Keep locations compact. Use cities or small islands, not countries ++ or regions, so that any future time zone changes do not split ++ locations into different time zones. E.g. prefer 'Paris' ++ to 'France', since France has had multiple time zones. ++ Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and ++ prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'. ++ The POSIX file name restrictions encourage this rule. ++ Use the most populous among locations in a zone, ++ e.g. prefer 'Shanghai' to 'Beijing'. Among locations with ++ similar populations, pick the best-known location, ++ e.g. prefer 'Rome' to 'Milan'. ++ Use the singular form, e.g. prefer 'Canary' to 'Canaries'. ++ Omit common suffixes like '_Islands' and '_City', unless that ++ would lead to ambiguity. E.g. prefer 'Cayman' to ++ 'Cayman_Islands' and 'Guatemala' to 'Guatemala_City', ++ but prefer 'Mexico_City' to 'Mexico' because the country ++ of Mexico has several time zones. ++ Use '_' to represent a space. ++ Omit '.' from abbreviations in names, e.g. prefer 'St_Helena' ++ to 'St._Helena'. ++ Do not change established names if they only marginally ++ violate the above rules. For example, don't change ++ the existing name 'Rome' to 'Milan' merely because ++ Milan's population has grown to be somewhat greater ++ than Rome's. ++ If a name is changed, put its old spelling in the 'backward' file. ++ This means old spellings will continue to work. ++ ++The file 'zone1970.tab' lists geographical locations used to name time ++zone rules. It is intended to be an exhaustive list of names for ++geographic regions as described above; this is a subset of the names ++in the data. Although a 'zone1970.tab' location's longitude ++corresponds to its LMT offset with one hour for every 15 degrees east ++longitude, this relationship is not exact. ++ ++Older versions of this package used a different naming scheme, ++and these older names are still supported. ++See the file 'backward' for most of these older names ++(e.g., 'US/Eastern' instead of 'America/New_York'). ++The other old-fashioned names still supported are ++'WET', 'CET', 'MET', and 'EET' (see the file 'europe'). ++ ++Older versions of this package defined legacy names that are ++incompatible with the first rule of location names, but which are ++still supported. These legacy names are mostly defined in the file ++'etcetera'. Also, the file 'backward' defines the legacy names ++'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file ++'northamerica' defines the legacy names 'EST5EDT', 'CST6CDT', ++'MST7MDT', and 'PST8PDT'. ++ ++Excluding 'backward' should not affect the other data. If ++'backward' is excluded, excluding 'etcetera' should not affect the ++remaining data. ++ ++ ++----- Time zone abbreviations ----- ++ ++When this package is installed, it generates time zone abbreviations ++like 'EST' to be compatible with human tradition and POSIX. ++Here are the general rules used for choosing time zone abbreviations, ++in decreasing order of importance: ++ ++ Use three or more characters that are ASCII alphanumerics or '+' or '-'. ++ Previous editions of this database also used characters like ++ ' ' and '?', but these characters have a special meaning to ++ the shell and cause commands like ++ set `date` ++ to have unexpected effects. ++ Previous editions of this rule required upper-case letters, ++ but the Congressman who introduced Chamorro Standard Time ++ preferred "ChST", so lower-case letters are now allowed. ++ Also, POSIX from 2001 on relaxed the rule to allow '-', '+', ++ and alphanumeric characters from the portable character set ++ in the current locale. In practice ASCII alphanumerics and ++ '+' and '-' are safe in all locales. ++ ++ In other words, in the C locale the POSIX extended regular ++ expression [-+[:alnum:]]{3,} should match the abbreviation. ++ This guarantees that all abbreviations could have been ++ specified by a POSIX TZ string. ++ ++ Use abbreviations that are in common use among English-speakers, ++ e.g. 'EST' for Eastern Standard Time in North America. ++ We assume that applications translate them to other languages ++ as part of the normal localization process; for example, ++ a French application might translate 'EST' to 'HNE'. ++ ++ For zones whose times are taken from a city's longitude, use the ++ traditional xMT notation, e.g. 'PMT' for Paris Mean Time. ++ The only name like this in current use is 'GMT'. ++ ++ Use 'LMT' for local mean time of locations before the introduction ++ of standard time; see "Scope of the tz database". ++ ++ If there is no common English abbreviation, use numeric offsets like ++ -05 and +0830 that are generated by zic's %z notation. ++ ++ [The remaining guidelines predate the introduction of %z. ++ They are problematic as they mean tz data entries invent ++ notation rather than record it. These guidelines are now ++ deprecated and the plan is to gradually move to %z for ++ inhabited locations and to "-00" for uninhabited locations.] ++ ++ If there is no common English abbreviation, abbreviate the English ++ translation of the usual phrase used by native speakers. ++ If this is not available or is a phrase mentioning the country ++ (e.g. "Cape Verde Time"), then: ++ ++ When a country is identified with a single or principal zone, ++ append 'T' to the country's ISO code, e.g. 'CVT' for ++ Cape Verde Time. For summer time append 'ST'; ++ for double summer time append 'DST'; etc. ++ Otherwise, take the first three letters of an English place ++ name identifying each zone and append 'T', 'ST', etc. ++ as before; e.g. 'VLAST' for VLAdivostok Summer Time. ++ ++ Use UT (with time zone abbreviation '-00') for locations while ++ uninhabited. The leading '-' is a flag that the time ++ zone is in some sense undefined; this notation is ++ derived from Internet RFC 3339. ++ ++Application writers should note that these abbreviations are ambiguous ++in practice: e.g. 'CST' has a different meaning in China than ++it does in the United States. In new applications, it's often better ++to use numeric UT offsets like '-0600' instead of time zone ++abbreviations like 'CST'; this avoids the ambiguity. ++ ++ ++----- Accuracy of the tz database ----- ++ ++The tz database is not authoritative, and it surely has errors. ++Corrections are welcome and encouraged; see the file CONTRIBUTING. ++Users requiring authoritative data should consult national standards ++bodies and the references cited in the database's comments. ++ ++Errors in the tz database arise from many sources: ++ ++ * The tz database predicts future time stamps, and current predictions ++ will be incorrect after future governments change the rules. ++ For example, if today someone schedules a meeting for 13:00 next ++ October 1, Casablanca time, and tomorrow Morocco changes its ++ daylight saving rules, software can mess up after the rule change ++ if it blithely relies on conversions made before the change. ++ ++ * The pre-1970 entries in this database cover only a tiny sliver of how ++ clocks actually behaved; the vast majority of the necessary ++ information was lost or never recorded. Thousands more zones would ++ be needed if the tz database's scope were extended to cover even ++ just the known or guessed history of standard time; for example, ++ the current single entry for France would need to split into dozens ++ of entries, perhaps hundreds. And in most of the world even this ++ approach would be misleading due to widespread disagreement or ++ indifference about what times should be observed. In her 2015 book ++ "The Global Transformation of Time, 1870-1950", Vanessa Ogle writes ++ "Outside of Europe and North America there was no system of time ++ zones at all, often not even a stable landscape of mean times, ++ prior to the middle decades of the twentieth century". See: ++ Timothy Shenk, Booked: A Global History of Time. Dissent 2015-12-17 ++ https://www.dissentmagazine.org/blog/booked-a-global-history-of-time-vanessa-ogle ++ ++ * Most of the pre-1970 data entries come from unreliable sources, often ++ astrology books that lack citations and whose compilers evidently ++ invented entries when the true facts were unknown, without ++ reporting which entries were known and which were invented. ++ These books often contradict each other or give implausible entries, ++ and on the rare occasions when they are checked they are ++ typically found to be incorrect. ++ ++ * For the UK the tz database relies on years of first-class work done by ++ Joseph Myers and others; see <http://www.polyomino.org.uk/british-time/>. ++ Other countries are not done nearly as well. ++ ++ * Sometimes, different people in the same city would maintain clocks ++ that differed significantly. Railway time was used by railroad ++ companies (which did not always agree with each other), ++ church-clock time was used for birth certificates, etc. ++ Often this was merely common practice, but sometimes it was set by law. ++ For example, from 1891 to 1911 the UT offset in France was legally ++ 0:09:21 outside train stations and 0:04:21 inside. ++ ++ * Although a named location in the tz database stands for the ++ containing region, its pre-1970 data entries are often accurate for ++ only a small subset of that region. For example, Europe/London ++ stands for the United Kingdom, but its pre-1847 times are valid ++ only for locations that have London's exact meridian, and its 1847 ++ transition to GMT is known to be valid only for the L&NW and the ++ Caledonian railways. ++ ++ * The tz database does not record the earliest time for which a zone's ++ data entries are thereafter valid for every location in the region. ++ For example, Europe/London is valid for all locations in its ++ region after GMT was made the standard time, but the date of ++ standardization (1880-08-02) is not in the tz database, other than ++ in commentary. For many zones the earliest time of validity is ++ unknown. ++ ++ * The tz database does not record a region's boundaries, and in many ++ cases the boundaries are not known. For example, the zone ++ America/Kentucky/Louisville represents a region around the city of ++ Louisville, the boundaries of which are unclear. ++ ++ * Changes that are modeled as instantaneous transitions in the tz ++ database were often spread out over hours, days, or even decades. ++ ++ * Even if the time is specified by law, locations sometimes ++ deliberately flout the law. ++ ++ * Early timekeeping practices, even assuming perfect clocks, were ++ often not specified to the accuracy that the tz database requires. ++ ++ * Sometimes historical timekeeping was specified more precisely ++ than what the tz database can handle. For example, from 1909 to ++ 1937 Netherlands clocks were legally UT +00:19:32.13, but the tz ++ database cannot represent the fractional second. ++ ++ * Even when all the timestamp transitions recorded by the tz database ++ are correct, the tz rules that generate them may not faithfully ++ reflect the historical rules. For example, from 1922 until World ++ War II the UK moved clocks forward the day following the third ++ Saturday in April unless that was Easter, in which case it moved ++ clocks forward the previous Sunday. Because the tz database has no ++ way to specify Easter, these exceptional years are entered as ++ separate tz Rule lines, even though the legal rules did not change. ++ ++ * The tz database models pre-standard time using the proleptic Gregorian ++ calendar and local mean time (LMT), but many people used other ++ calendars and other timescales. For example, the Roman Empire used ++ the Julian calendar, and had 12 varying-length daytime hours with a ++ non-hour-based system at night. ++ ++ * Early clocks were less reliable, and data entries do not represent ++ this unreliability. ++ ++ * As for leap seconds, civil time was not based on atomic time before ++ 1972, and we don't know the history of earth's rotation accurately ++ enough to map SI seconds to historical solar time to more than ++ about one-hour accuracy. See: Morrison LV, Stephenson FR. ++ Historical values of the Earth's clock error Delta T and the ++ calculation of eclipses. J Hist Astron. 2004;35:327-36 ++ <http://adsabs.harvard.edu/full/2004JHA....35..327M>; ++ Historical values of the Earth's clock error. J Hist Astron. 2005;36:339 ++ <http://adsabs.harvard.edu/full/2005JHA....36..339M>. ++ ++ * The relationship between POSIX time (that is, UTC but ignoring leap ++ seconds) and UTC is not agreed upon after 1972. Although the POSIX ++ clock officially stops during an inserted leap second, at least one ++ proposed standard has it jumping back a second instead; and in ++ practice POSIX clocks more typically either progress glacially during ++ a leap second, or are slightly slowed while near a leap second. ++ ++ * The tz database does not represent how uncertain its information is. ++ Ideally it would contain information about when data entries are ++ incomplete or dicey. Partial temporal knowledge is a field of ++ active research, though, and it's not clear how to apply it here. ++ ++In short, many, perhaps most, of the tz database's pre-1970 and future ++time stamps are either wrong or misleading. Any attempt to pass the ++tz database off as the definition of time should be unacceptable to ++anybody who cares about the facts. In particular, the tz database's ++LMT offsets should not be considered meaningful, and should not prompt ++creation of zones merely because two locations differ in LMT or ++transitioned to standard time at different dates. ++ ++ ++----- Time and date functions ----- ++ ++The tz code contains time and date functions that are upwards ++compatible with those of POSIX. ++ ++POSIX has the following properties and limitations. ++ ++* In POSIX, time display in a process is controlled by the ++ environment variable TZ. Unfortunately, the POSIX TZ string takes ++ a form that is hard to describe and is error-prone in practice. ++ Also, POSIX TZ strings can't deal with other (for example, Israeli) ++ daylight saving time rules, or situations where more than two ++ time zone abbreviations are used in an area. ++ ++ The POSIX TZ string takes the following form: ++ ++ stdoffset[dst[offset][,date[/time],date[/time]]] ++ ++ where: ++ ++ std and dst ++ are 3 or more characters specifying the standard ++ and daylight saving time (DST) zone names. ++ Starting with POSIX.1-2001, std and dst may also be ++ in a quoted form like "<UTC+10>"; this allows ++ "+" and "-" in the names. ++ offset ++ is of the form '[+-]hh:[mm[:ss]]' and specifies the ++ offset west of UT. 'hh' may be a single digit; 0<=hh<=24. ++ The default DST offset is one hour ahead of standard time. ++ date[/time],date[/time] ++ specifies the beginning and end of DST. If this is absent, ++ the system supplies its own rules for DST, and these can ++ differ from year to year; typically US DST rules are used. ++ time ++ takes the form 'hh:[mm[:ss]]' and defaults to 02:00. ++ This is the same format as the offset, except that a ++ leading '+' or '-' is not allowed. ++ date ++ takes one of the following forms: ++ Jn (1<=n<=365) ++ origin-1 day number not counting February 29 ++ n (0<=n<=365) ++ origin-0 day number counting February 29 if present ++ Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) ++ for the dth day of week n of month m of the year, ++ where week 1 is the first week in which day d appears, ++ and '5' stands for the last week in which day d appears ++ (which may be either the 4th or 5th week). ++ Typically, this is the only useful form; ++ the n and Jn forms are rarely used. ++ ++ Here is an example POSIX TZ string, for US Pacific time using rules ++ appropriate from 1987 through 2006: ++ ++ TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00' ++ ++ This POSIX TZ string is hard to remember, and mishandles time stamps ++ before 1987 and after 2006. With this package you can use this ++ instead: ++ ++ TZ='America/Los_Angeles' ++ ++* POSIX does not define the exact meaning of TZ values like "EST5EDT". ++ Typically the current US DST rules are used to interpret such values, ++ but this means that the US DST rules are compiled into each program ++ that does time conversion. This means that when US time conversion ++ rules change (as in the United States in 1987), all programs that ++ do time conversion must be recompiled to ensure proper results. ++ ++* The TZ environment variable is process-global, which makes it hard ++ to write efficient, thread-safe applications that need access ++ to multiple time zones. ++ ++* In POSIX, there's no tamper-proof way for a process to learn the ++ system's best idea of local wall clock. (This is important for ++ applications that an administrator wants used only at certain times - ++ without regard to whether the user has fiddled the "TZ" environment ++ variable. While an administrator can "do everything in UTC" to get ++ around the problem, doing so is inconvenient and precludes handling ++ daylight saving time shifts - as might be required to limit phone ++ calls to off-peak hours.) ++ ++* POSIX provides no convenient and efficient way to determine the UT ++ offset and time zone abbreviation of arbitrary time stamps, ++ particularly for time zone settings that do not fit into the ++ POSIX model. ++ ++* POSIX requires that systems ignore leap seconds. ++ ++* The tz code attempts to support all the time_t implementations ++ allowed by POSIX. The time_t type represents a nonnegative count of ++ seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds. ++ In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit ++ signed time_t values stop working after 2038-01-19 03:14:07 UTC, so ++ new implementations these days typically use a signed 64-bit integer. ++ Unsigned 32-bit integers are used on one or two platforms, ++ and 36-bit and 40-bit integers are also used occasionally. ++ Although earlier POSIX versions allowed time_t to be a ++ floating-point type, this was not supported by any practical ++ systems, and POSIX.1-2013 and the tz code both require time_t ++ to be an integer type. ++ ++These are the extensions that have been made to the POSIX functions: ++ ++* The "TZ" environment variable is used in generating the name of a file ++ from which time zone information is read (or is interpreted a la ++ POSIX); "TZ" is no longer constrained to be a three-letter time zone ++ name followed by a number of hours and an optional three-letter ++ daylight time zone name. The daylight saving time rules to be used ++ for a particular time zone are encoded in the time zone file; ++ the format of the file allows U.S., Australian, and other rules to be ++ encoded, and allows for situations where more than two time zone ++ abbreviations are used. ++ ++ It was recognized that allowing the "TZ" environment variable to ++ take on values such as "America/New_York" might cause "old" programs ++ (that expect "TZ" to have a certain form) to operate incorrectly; ++ consideration was given to using some other environment variable ++ (for example, "TIMEZONE") to hold the string used to generate the ++ time zone information file name. In the end, however, it was decided ++ to continue using "TZ": it is widely used for time zone purposes; ++ separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; ++ and systems where "new" forms of "TZ" might cause problems can simply ++ use TZ values such as "EST5EDT" which can be used both by ++ "new" programs (a la POSIX) and "old" programs (as zone names and ++ offsets). ++ ++* The code supports platforms with a UT offset member in struct tm, ++ e.g., tm_gmtoff. ++ ++* The code supports platforms with a time zone abbreviation member in ++ struct tm, e.g., tm_zone. ++ ++* Since the "TZ" environment variable can now be used to control time ++ conversion, the "daylight" and "timezone" variables are no longer ++ needed. (These variables are defined and set by "tzset"; however, their ++ values will not be used by "localtime.") ++ ++* Functions tzalloc, tzfree, localtime_rz, and mktime_z for ++ more-efficient thread-safe applications that need to use ++ multiple time zones. The tzalloc and tzfree functions ++ allocate and free objects of type timezone_t, and localtime_rz ++ and mktime_z are like localtime_r and mktime with an extra ++ timezone_t argument. The functions were inspired by NetBSD. ++ ++* A function "tzsetwall" has been added to arrange for the system's ++ best approximation to local wall clock time to be delivered by ++ subsequent calls to "localtime." Source code for portable ++ applications that "must" run on local wall clock time should call ++ "tzsetwall();" if such code is moved to "old" systems that don't ++ provide tzsetwall, you won't be able to generate an executable program. ++ (These time zone functions also arrange for local wall clock time to be ++ used if tzset is called - directly or indirectly - and there's no "TZ" ++ environment variable; portable applications should not, however, rely ++ on this behavior since it's not the way SVR2 systems behave.) ++ ++* Negative time_t values are supported, on systems where time_t is signed. ++ ++* These functions can account for leap seconds, thanks to Bradley White. ++ ++Points of interest to folks with other systems: ++ ++* Code compatible with this package is already part of many platforms, ++ including GNU/Linux, Android, the BSDs, Chromium OS, Cygwin, AIX, iOS, ++ BlackBery 10, macOS, Microsoft Windows, OpenVMS, and Solaris. ++ On such hosts, the primary use of this package ++ is to update obsolete time zone rule tables. ++ To do this, you may need to compile the time zone compiler ++ 'zic' supplied with this package instead of using the system 'zic', ++ since the format of zic's input is occasionally extended, ++ and a platform may still be shipping an older zic. ++ ++* The UNIX Version 7 "timezone" function is not present in this package; ++ it's impossible to reliably map timezone's arguments (a "minutes west ++ of GMT" value and a "daylight saving time in effect" flag) to a ++ time zone abbreviation, and we refuse to guess. ++ Programs that in the past used the timezone function may now examine ++ tzname[localtime(&clock)->tm_isdst] to learn the correct time ++ zone abbreviation to use. Alternatively, use ++ localtime(&clock)->tm_zone if this has been enabled. ++ ++* The 4.2BSD gettimeofday function is not used in this package. ++ This formerly let users obtain the current UTC offset and DST flag, ++ but this functionality was removed in later versions of BSD. ++ ++* In SVR2, time conversion fails for near-minimum or near-maximum ++ time_t values when doing conversions for places that don't use UT. ++ This package takes care to do these conversions correctly. ++ A comment in the source code tells how to get compatibly wrong ++ results. ++ ++The functions that are conditionally compiled if STD_INSPIRED is defined ++should, at this point, be looked on primarily as food for thought. They are ++not in any sense "standard compatible" - some are not, in fact, specified in ++*any* standard. They do, however, represent responses of various authors to ++standardization proposals. ++ ++Other time conversion proposals, in particular the one developed by folks at ++Hewlett Packard, offer a wider selection of functions that provide capabilities ++beyond those provided here. The absence of such functions from this package ++is not meant to discourage the development, standardization, or use of such ++functions. Rather, their absence reflects the decision to make this package ++contain valid extensions to POSIX, to ensure its broad acceptability. If ++more powerful time conversion functions can be standardized, so much the ++better. ++ ++ ++----- Interface stability ----- ++ ++The tz code and data supply the following interfaces: ++ ++ * A set of zone names as per "Names of time zone rules" above. ++ ++ * Library functions described in "Time and date functions" above. ++ ++ * The programs tzselect, zdump, and zic, documented in their man pages. ++ ++ * The format of zic input files, documented in the zic man page. ++ ++ * The format of zic output files, documented in the tzfile man page. ++ ++ * The format of zone table files, documented in zone1970.tab. ++ ++ * The format of the country code file, documented in iso3166.tab. ++ ++When these interfaces are changed, an effort is made to preserve ++backward compatibility. For example, tz data files typically do not ++rely on recently-added zic features, so that users can run older zic ++versions to process newer data files. ++ ++Interfaces not listed above are less stable. For example, users ++should not rely on particular UT offsets or abbreviations for time ++stamps, as data entries are often based on guesswork and these guesses ++may be corrected or improved. ++ ++ ++----- Calendrical issues ----- ++ ++Calendrical issues are a bit out of scope for a time zone database, ++but they indicate the sort of problems that we would run into if we ++extended the time zone database further into the past. An excellent ++resource in this area is Nachum Dershowitz and Edward M. Reingold, ++Calendrical Calculations: Third Edition, Cambridge University Press (2008) ++<http://emr.cs.iit.edu/home/reingold/calendar-book/third-edition/>. ++Other information and sources are given below. They sometimes disagree. ++ ++ ++France ++ ++Gregorian calendar adopted 1582-12-20. ++French Revolutionary calendar used 1793-11-24 through 1805-12-31, ++and (in Paris only) 1871-05-06 through 1871-05-23. ++ ++ ++Russia ++ ++From Chris Carrier (1996-12-02): ++On 1929-10-01 the Soviet Union instituted an "Eternal Calendar" ++with 30-day months plus 5 holidays, with a 5-day week. ++On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the ++Gregorian calendar while retaining the 6-day week; on 1940-06-27 it ++reverted to the 7-day week. With the 6-day week the usual days ++off were the 6th, 12th, 18th, 24th and 30th of the month. ++(Source: Evitiar Zerubavel, _The Seven Day Circle_) ++ ++ ++Mark Brader reported a similar story in "The Book of Calendars", edited ++by Frank Parise (1982, Facts on File, ISBN 0-8719-6467-8), page 377.

Grotefend, _Taschenbuch der Zeitrechnung des deutschen ++Mittelalters und der Neuzeit_, herausgegeben von Dr. O. Grotefend ++(Hannover: Hahnsche Buchhandlung, 1941), pp. 26-28. ++ ++ ++----- Time and time zones on Mars ----- ++ ++Some people's work schedules use Mars time. Jet Propulsion Laboratory ++(JPL) coordinators have kept Mars time on and off at least since 1997 ++for the Mars Pathfinder mission. Some of their family members have ++also adapted to Mars time. Dozens of special Mars watches were built ++for JPL workers who kept Mars time during the Mars Exploration ++Rovers mission (2004). These timepieces look like normal Seikos and ++Citizens but use Mars seconds rather than terrestrial seconds. ++ ++A Mars solar day is called a "sol" and has a mean period equal to ++about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is ++divided into a conventional 24-hour clock, so each Mars second equals ++about 1.02749125 terrestrial seconds. ++ ++The prime meridian of Mars goes through the center of the crater ++Airy-0, named in honor of the British astronomer who built the ++Greenwich telescope that defines Earth's prime meridian. Mean solar ++time on the Mars prime meridian is called Mars Coordinated Time (MTC). ++ ++Each landed mission on Mars has adopted a different reference for ++solar time keeping, so there is no real standard for Mars time zones. ++For example, the Mars Exploration Rover project (2004) defined two ++time zones "Local Solar Time A" and "Local Solar Time B" for its two ++missions, each zone designed so that its time equals local true solar ++time at approximately the middle of the nominal mission. Such a "time ++zone" is not particularly suited for any application other than the ++mission itself. ++ ++Many calendars have been proposed for Mars, but none have achieved ++wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a ++sequential count of Mars solar days elapsed since about 1873-12-29 ++12:00 GMT. ++ ++The tz database does not currently support Mars time, but it is ++documented here in the hopes that support will be added eventually. ++ ++Sources: ++ ++Michael Allison and Robert Schmunk, ++"Technical Notes on Mars Solar Time as Adopted by the Mars24 Sunclock" ++<http://www.giss.nasa.gov/tools/mars24/help/notes.html> (2012-08-08). ++ ++Jia-Rui Chong, "Workdays Fit for a Martian", Los Angeles Times ++<http://articles.latimes.com/2004/jan/14/science/sci-marstime14> ++(2004-01-14), pp A1, A20-A21. ++ ++Tom Chmielewski, "Jet Lag Is Worse on Mars", The Atlantic (2015-02-26) ++<http://www.theatlantic.com/technology/archive/2015/02/jet-lag-is-worse-on-mars/386033/> ++ ++----- ++ ++This file is in the public domain, so clarified as of 2009-05-17 by ++Arthur David Olson. ++ ++----- ++Local Variables: ++coding: utf-8 ++End: +--- contrib/tzdata/africa.orig ++++ contrib/tzdata/africa +@@ -1,32 +1,32 @@ + # This file is in the public domain, so clarified as of + # 2009-05-17 by Arthur David Olson. + +-# This data is by no means authoritative; if you think you know better, ++# This file is by no means authoritative; if you think you know better, + # go ahead and edit the file (and please send any changes to +-# tz@iana.org for general use in the future). ++# tz@iana.org for general use in the future).
