Shanks, The International Atlas (3rd edition), +# San Diego: ACS Publications, Inc. (1991). +# Except where otherwise noted, it is the source for the data below. +# +# I added so many Zone names that the old, mostly flat name space was unwieldy. +# So I renamed the Zones to 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. +# For example, the old zone name `Egypt' is now `Africa/Cairo'. +# +# Here are the general rules I used for choosing location names, +# in decreasing order of importance: +# +# Use only valid Posix file names. Use only Ascii letters, digits, `.', +# `-' and `_'. Do not exceed 14 characters or start with `-'. +# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'. +# Include at least one location per time zone rule set per country. +# One such location is enough. +# If a name is ambiguous, use a less ambiguous alternative; +# e.g. many cities are named San Jose 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 traditional English spelling, e.g. prefer `Rome' to `Roma', and +# prefer `Athens' to the true name (which uses Greek letters). +# The Posix file name restrictions encourage this rule. +# Use the most populous among locations in a country's time 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'. +# +# I made up the following time zone abbreviations; corrections are welcome! +# LMT Local Mean Time +# -2:00 CVT Cape Verde Time (no longer used) +# -1:00 AAT Atlantic Africa Time +# 0:00 WAT West Africa Time +# 1:00 CAT Central Africa Time +# 2:00 SAT South Africa Time +# 3:00 EAT East Africa Time +# 4:00 SMT Seychelles and Mascarene Time +# The final `T' is replaced by `ST' for summer time, e.g. `SAST'. +# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after. + + +# Algeria +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule Algeria 1911 only -

If Rosh Hashanah occurs on Monday or Tuesday, we -# begin saying the Selichot from the Sunday of the preceding week. -# -# This, too, varies from year to year on the Gregorian calendar and, thus, -# two explicit timezone rules are required for each Gregorian year. +# Shanks gives the following rules for Jerusalem from 1918 through 1991. +# After 1989 Shanks often disagrees with Silverberg; we go with Silverberg. + +# From Shanks (1991): +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule Zion 1918 only - Jan 1 0:00 0 S +Rule Zion 1940 only - Jun 1 0:00 1:00 D +Rule Zion 1942 1944 - Nov 1 0:00 0 S +Rule Zion 1943 only - Apr 1 2:00 1:00 D +Rule Zion 1944 only - Apr 1 0:00 1:00 D +Rule Zion 1945 only - Apr 16 0:00 1:00 D +Rule Zion 1945 only - Nov 1 2:00 0 S +Rule Zion 1946 only - Apr 16 2:00 1:00 D +Rule Zion 1946 only - Nov 1 0:00 0 S +Rule Zion 1948 only - May 23 0:00 2:00 DD +Rule Zion 1948 only - Sep 1 0:00 1:00 D +Rule Zion 1948 1949 - Nov 1 2:00 0 S +Rule Zion 1949 only - May 1 0:00 1:00 D +Rule Zion 1950 only - Apr 16 0:00 1:00 D +Rule Zion 1950 only - Sep 15 3:00 0 S +Rule Zion 1951 only - Apr 1 0:00 1:00 D +Rule Zion 1951 only - Nov 11 3:00 0 S +Rule Zion 1952 only - Apr 20 2:00 1:00 D +Rule Zion 1952 only - Oct 19 3:00 0 S +Rule Zion 1953 only - Apr 12 2:00 1:00 D +Rule Zion 1953 only - Sep 13 3:00 0 S +Rule Zion 1954 only - Jun 13 0:00 1:00 D +Rule Zion 1954 only - Sep 12 0:00 0 S +Rule Zion 1955 only - Jun 11 2:00 1:00 D +Rule Zion 1955 only - Sep 11 0:00 0 S +Rule Zion 1956 only - Jun 3 0:00 1:00 D +Rule Zion 1956 only - Sep 30 3:00 0 S +Rule Zion 1957 only - Apr 29 2:00 1:00 D +Rule Zion 1957 only - Sep 22 0:00 0 S +Rule Zion 1974 only - Jul 7 0:00 1:00 D +Rule Zion 1974 only - Oct 13 0:00 0 S +Rule Zion 1975 only - Apr 20 0:00 1:00 D +Rule Zion 1975 only - Aug 31 0:00 0 S +Rule Zion 1985 only - Apr 14 0:00 1:00 D +Rule Zion 1985 only - Sep 15 0:00 0 S +Rule Zion 1986 only - May 18 0:00 1:00 D +Rule Zion 1986 only - Sep 7 0:00 0 S +Rule Zion 1987 only - Apr 15 0:00 1:00 D +Rule Zion 1987 only - Sep 13 0:00 0 S +Rule Zion 1988 only - Apr 9 0:00 1:00 D +Rule Zion 1988 only - Sep 3 0:00 0 S +#Rule Zion 1989 only - Apr 29 0:00 1:00 D +#Rule Zion 1989 only - Sep 2 0:00 0 S +#Rule Zion 1990 only - Mar 25 0:00 1:00 D +#Rule Zion 1990 only - Aug 26 0:00 0 S +#Rule Zion 1991 only - Mar 10 0:00 1:00 D +#Rule Zion 1991 only - Sep 1 0:00 0 S + +# From Ephraim Silverberg (September 5, 1993): # -# [**] actually Saturday night as the Jewish day commences at nightfall. -# [***] the Jewish Lunar New Year. +# According to the Office of the Secretary General of the Ministry of +# Interior, there is NO set rule for Daylight-Savings/Standard time changes. +# Each year they decide anew what havoc to wreak on the country.

Basil Hall, RN (1788-1844), +# famed explorer and former Commissioner for Longitude. +# The first railway to adopt London time was the Great Western Railway +# in November 1840; other railways followed suit, and by 1847 most +# (though not all) railways used London time. On 1847 Sep 22 the +# Railway Clearing House, an industry standards body, recommended that GMT be +# adopted at all stations; the January 1848 Bradshaw's lists most major +# railways as using GMT. By 1855 the vast majority of public +# clocks in Britain were set to GMT (though some, like the Great Clock +# in Tom Tower at Christ Church, Oxford, were fitted with two minute hands, +# one for local time and one for GMT). The last major holdout was the legal +# system, which stubbornly stuck to local time for many years, leading +# to oddities like polls opening at 08:13 and closing at 16:13. +# The legal system finally switched to GMT when the Statutes (Definition +# of Time) Act took effect; it received the Royal Assent on 1880 Aug 2. +# +# In the tables below, we condense this complicated story into a single +# transition date for London, namely 1847 Sep 22. We don't know as much +# about Dublin, so we use 1880 Aug 2, the legal transition time. + +# From Peter Ilieve <peter@memex.co.uk> (July 4, 1989): +# +# From the UK Government paper "Summer Time: A Consultation Document" +# (HMSO Cm722 June 1989), which is about the possibility of the UK moving +# into the central European timezone and synchronising its summer time with +# the rest of Europe (by moving the end date back a month to end Sep., +# the start dates are already the same). +# +# Summer time was not observed before 1916. +# It was introduced in the First World War in response to its introduction +# by Germany in March 1916. +# During the Second World War normal summer time was used in Winter and double +# summer time was used in Summer. +# Between 1968 and 1971 GMT+1 was used all year as an experiment. +# This caused voluble objections in Scotland and the experiment was judged +# a failure. +# +# Although it does not say what happens in Europe, it does say that most +# of Europe did not use summer time until 1979, presumably dropping it +# after the 1st and/or 2nd war. +# +# Note that this is not necessarily accurate for Eire. # -# The starting and ending dates below (from which the rules are derived) -# are from Whitaker's Almanack for 1987, page 146. -# 1960 is the earliest year for which dates are given; -# Whitaker's notes that British Summer Time (and, in some years, Double Summer -# Time) was observed in earlier years but does not give start and end dates. +# The paper gives a complete record of dates from 1916, and dates up to 1992. +# The intention is to have the new system, if any, start in 1993. +# The dates are (copied exactly from the table in the paper): +# +# Summer Time Double Summer Time +# Year Start End Start End +# 1916 21 May 1 October +# 1917 8 April 17 September +# 1918 24 March 30 September +# 1919 30 March 29 September +# 1920 28 March 25 October +# (extended from +# 27 Sep. because +# of coal strike) +# +# 1921 3 April 3 October +# 1922 26 March 8 October +# 1923 22 April 16 September +# 1924 20 April 21 September [Some of the dates in these +# 1925 to 3rd Sunday 1st Sunday three lines are incorrect; +# 1938 in April in October -- see below.] +# +# 1939 16 April 19 November +# 1940 25 February continued +# 1941 continued continued 4 May 10 August +# 1942 continued continued 5 April 9 August +# 1943 continued continued 4 April 15 August +# 1944 continued continued 2 April 17 September +# 1945 continued 7 October 2 April 15 July +# +# 1946 14 April 6 October +# 1947 16 March 2 November 13 April 10 August +# 1948 14 March 31 October +# 1949 3 April 30 October +# 1950 16 April 22 October +# 1951 15 April 21 October +# 1952 20 April 26 October +# +# 1953 19 April 4 October +# 1954 11 April 3 October +# 1955 17 April 2 October +# 1956 15 April 7 October [`15 April' is disputed; see below.] +# 1957 14 April 6 October +# 1958 20 April 5 October +# 1959 19 April 4 October +# 1960 10 April 2 October +# +# 1961 26 March 29 October +# 1962 25 March 28 October +# 1963 31 March 27 October +# 1964 22 March 25 October +# 1965 21 March 24 October +# 1966 20 March 23 October +# 1967 19 March 29 October +# +# 1968 18 February continued +# 1969 continued continued +# 1970 continued continued +# 1971 continued 31 October +# 1972 19 March 29 October +# 1973 18 March 28 October +# 1974 17 March 27 October +# +# 1975 16 March 26 October +# 1976 21 March 24 October +# 1977 20 March 23 October +# 1978 19 March 29 October +# 1979 18 March 28 October +# 1980 16 March 26 October +# 1981 29 March 25 October +# +# 1982 28 March 24 October +# 1983 27 March 23 October +# 1984 25 March 28 October +# 1985 31 March 27 October +# 1986 30 March 26 October +# 1987 29 March 25 October +# 1988 27 March 23 October +# +# 1989 26 March 29 October +# 1990 25 March 28 October +# 1991 31 March 27 October +# 1992 29 March 25 October +# +# These dates agree with the ones from Whitaker's Almanac for 1960--87. . . + +# From Peter Ilieve (peter@memex.co.uk) (October 18, 1993) +# +# I made a transcription error in my table for 1924.

It specifies an offset of 1 hour. +# +# - The Time (Ireland) Act, 1916 +# +# This abolishes Dublin mean time on 02:00 DMT 1 October 1916. +# It repeals that section of the Statutes (Definition of Time) Act, 1880 +# that specifies DMT. It is therefore a safe bet that DMT existed at least +# from 1880 and was the only alternative standard time in the UK. +# +# - The Summer Time Act, 1922 +# +# This specifies an offset of 1 hour and dates of the day after the third +# Saturday in April, unless that be Easter, in which case it is the day after +# the second Saturday, and the day after the third Saturday in September. +# The time is 02:00 GMT. It applied in 1922 and 1923, and longer if Parliament +# so approved. +# +# It specifically states that it applies to Northern Ireland, the Channel +# Islands, and the Isle of Man. +# +# - The Summer Time Act, 1925 +# +# This makes the 1922 Act permanent, with a change to the end date to the +# day after the first Saturday in October.

It also said it +# applied to Jersey, Guernsey and the Isle of Man unless they passed +# measures saying it didn't. +# +# - The Manx Time Act, 1968 +# +# This is an Act of Tynwald (the Isle of Man Parliament) that said that +# henceforth Manx time would be the same as the time in Great Britain. +# +# - The Summer Time Act, 1972 +# +# This specified a reversion to normal summer time behaviour with a start +# date of the day after the third Saturday in March, unless that is Easter, +# when it is the day after the second Saturday, and an end date of the day +# after the fourth Saturday in October. Times are at 02:00 GMT, offset is +# 1 hour. +# +# It has the same wording about extent as the British Standard Time Act, 1968, +# applying to Northern Ireland unconditionally and to Jersey, Guernsey and the +# Isle of Man if they don't do something about it. +# +# (I am missing various Summer Time Orders that modified the 1972 Act to +# harmonise with the EC since 1981. The major change is that the time changes +# to 01:00 GMT.) +# +# - The Summer Time Order, 1992, SI 1992/1729 [SI == Statutary Instrument] +# +# This specifies dates of: +# Start End +# 1993 28 March 24 October +# 1994 27 March 23 October +# All start and end times are at 01:00 GMT. +# This is as far as it goes at present. A new EC directive is expected soon +# and this will lead to a new Summer Time Order implementing it in the UK. +# +# - Some text on the extent of Acts, from Halsbury's Statutes +# +# `An Act of the United Kingdom Parliament is to be construed prima facie +# to apply to the whole of the United Kingdom and not to any place outside. +# [...] The expression "United Kingdom" for this purpose includes (since +# 1922) Great Britain (ie.
