# Britain (United Kingdom) and Ireland (Eire)

# From Peter Ilieve <peter@memex.co.uk> (1994-07-06):
#
# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
# historical vistas along the Thames in west London. There was a photo
# and a sketch map showing some of the sightlines involved. One paragraph
# of the text said:
#
# `An old stone obelisk marking a forgotten terrestrial meridian stands
# beside the river at Kew. In the 18th century, before time and longitude
# was standardised by the Royal Observatory in Greenwich, scholars observed
# this stone and the movement of stars from Kew Observatory nearby. They
# made their calculations and set the time for the Horse Guards and Parliament,
# but now the stone is obscured by scrubwood and can only be seen by walking
# along the towpath within a few yards of it.'
#
# I have a one inch to one mile map of London and my estimate of the stone's
# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
# be within about +-2". The Ordnance Survey grid reference is TQ172761.
#
# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]

# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
#
# Howse writes that Britain was the first country to use standard time.
# The railways cared most about the inconsistencies of local mean time,
# and it was they who forced a uniform time on the country.
# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
# and was popularized by Abraham Follett Osler (1808-1903).
# 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 1847-09-22 the
# Railway Clearing House, an industry standards body, recommended that GMT be
# adopted at all stations as soon as the General Post Office permitted it.
# The transition occurred on 12-01 for the L&NW, the Caledonian,
# and presumably other railways; the January 1848 Bradshaw's lists many
# railways as using GMT.  By 1855 the vast majority of public
# clocks in Britain were set to GMT (though some, like the great clock
# on 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 1880-08-02.
#
# In the tables below, we condense this complicated story into a single
# transition date for London, namely 1847-12-01.  We don't know as much
# about Dublin, so we use 1880-08-02, the legal transition time.

# From Paul Eggert (1999-01-30):
# Summer Time was first seriously proposed by William Willett (1857-1915),
# a London builder and member of the Royal Astronomical Society
# who circulated a pamphlet ``The Waste of Daylight'' (1907)
# that proposed advancing clocks 20 minutes on each of four Sundays in April,
# and retarding them by the same amount on four Sundays in September.
# A bill was drafted in 1909 and introduced in Parliament several times,
# but it met with ridicule and opposition, especially from farming interests.
# One-hour Summer Time was eventually adopted as a wartime measure in 1916.
# See:
# <a href="http://www.the-times.co.uk/news/pages/tim/2000/05/18/x-timcrtcrt01011.html">
# Summer Time Arrives Early, The Times (2000-05-18)
# </a>
# A monument was erected in 1927 to Willett, in an open space in a 45-acre wood
# near Chiselhurst, Kent that was purchased by popular subscription and open
# to the public.

# From Paul Eggert (1996-09-03):
# The OED Supplement says that the English originally said ``Daylight Saving''
# when they were debating the adoption of DST in 1908; but by 1916 this
# term appears only in quotes taken from DST's opponents, whereas the
# proponents (who eventually won the argument) are quoted as using ``Summer''.

# From Arthur David Olson (1989-01-19):
#
# A source at the British Information Office in New York avers that it's
# known as "British" Summer Time in all parts of the United Kingdom.

# Date: 4 Jan 89 08:57:25 GMT (Wed)
# From: Jonathan Leffler <nih-csl!uunet!mcvax!sphinx.co.uk!john>
# [British Summer Time] is fixed annually by Act of Parliament.
# If you can predict what Parliament will do, you should be in
# politics making a fortune, not computing.

# From Chris Carrier <72157.3334@CompuServe.COM> (1996-06-14):
# I remember reading in various wartime issues of the London Times the
# acronym BDST for British Double Summer Time.  Look for the published
# time of sunrise and sunset in The Times, when BDST was in effect, and
# if you find a zone reference it will say, "All times B.D.S.T."

# From Joseph S. Myers (1999-09-02):
# ... some military cables (WO 219/4100 - this is a copy from the
# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).

# From Joseph S. Myers (2000-10-03):
# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
# Alexander Maxwell of the Home Office asking whether there was any
# official designation; the reply of the 21st was that there wasn't
# but he couldn't think of anything better than the "Double British
# Summer Time" that the BBC had been using informally.
# http://student.cusu.cam.ac.uk/~jsm28/british-time/bbc-19410418.png
# http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png

# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
# [N]o official designation has as far as I know been adopted for the time
# which is to be introduced in May....
# I cannot think of anything better than "Double British Summer Time"
# which could not be said to run counter to any official description.

# From Paul Eggert (2000-10-02):
# Howse writes (p 157) `DBST' too, but `BDST' seems to have been common
# and follows the more usual convention of putting the location name first,
# so we use `BDST'.

# Peter Ilieve <peter@aldie.co.uk> (1998-04-19) described at length
# the history of summer time legislation in the United Kingdom.
# Since 1998 Joseph S. Myers <jsm28@cam.ac.uk> has been updating
# and extending this list, which can be found in
# <a href="http://student.cusu.cam.ac.uk/~jsm28/british-time/">
# History of legal time in Britain
# </a> (2000-02-12).

# From Joseph S. Myers <jsm28@cam.ac.uk> (1998-01-06):
#
# The legal time in the UK outside of summer time is definitely GMT, not UTC;
# see Lord Tanlaw's speech
# <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn/lds97/text/70611-20.htm#70611-20_head0">
# (Lords Hansard 11 June 1997 columns 964 to 976)
# </a>.

# From Paul Eggert (2000-02-17):
#
# For lack of other data, we'll follow Shanks for Eire in 1940-1948.
#
# Given Ilieve and Myers's data, the following claims by Shanks are incorrect:
#     * Wales did not switch from GMT to daylight saving time until
#	1921 Apr 3, when they began to conform with the rest of Great Britain.
# Actually, Wales was identical after 1880.
#     * Eire had two transitions on 1916 Oct 1.
# It actually just had one transition.
#     * Northern Ireland used single daylight saving time throughout WW II.
# Actually, it conformed to Britain.
#     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
# Actually, that date saw the usual switch to summer time.
# Standard time was not changed until 1968-10-27 (the clocks didn't change).
#
# Here is another incorrect claim by Shanks:
#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
#	to daylight saving time until 1921 Apr 3, when they began to
#	conform with Great Britain.
# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
#
# The following claim by Shanks is possible though doubtful;
# we'll ignore it for now.
#     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
#
#
# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.

# From Paul Eggert (1999-03-28):
# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
# (CT), equivalent to French civil time.
# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
# trains between Dollands Moor (the freight facility next door)
# and Frethun run in CT.
# My admittedly uninformed guess is that the terminal has two authorities,
# the French concession operators and the British civil authorities,
# and that the time depends on who you're talking to.
# If, say, the British police were called to the station for some reason,
# I would expect the official police report to use GMT/BST and not CET/CEST.
# This is a borderline case, but for now let's stick to GMT/BST.

# From an anonymous contributor (1996-06-02):
# The law governing time in Ireland is under Statutory Instrument SI 395/94,
# which gives force to European Union 7th Council Directive # 94/21/EC.
# Under this directive, the Minister for Justice in Ireland makes appropriate
# regulations. I spoke this morning with the Secretary of the Department of
# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
# "Irish Summer Time", abbreviated to "IST".

# Previous editions of this database used abbreviations like MET DST
# for Central European Summer Time, but this didn't agree with common usage.

# From Markus Kuhn <mskuhn@unrza3.dialin.rrze.uni-erlangen.de> (1996-07-12):
# The official German names ... are
#
#	Mitteleuropaeische Zeit (MEZ)         = UTC+01:00
#	Mitteleuropaeische Sommerzeit (MESZ)  = UTC+02:00
#
# as defined in the German Time Act (Gesetz ueber die Zeitbestimmung (ZeitG),
# 1978-07-25, Bundesgesetzblatt, Jahrgang 1978, Teil I, S. 1110-1111)....
# I wrote ... to the German Federal Physical-Technical Institution
#
#	Physikalisch-Technische Bundesanstalt (PTB)
#	Laboratorium 4.41 "Zeiteinheit"
#	Postfach 3345
#	D-38023 Braunschweig
#	phone: +49 531 592-0
#
# ... I received today an answer letter from Dr. Peter Hetzel, head of the PTB
# department for time and frequency transmission.  He explained that the
# PTB translates MEZ and MESZ into English as
#
#	Central European Time (CET)         = UTC+01:00
#	Central European Summer Time (CEST) = UTC+02:00

# Estonia
# From Peter Ilieve <peter@memex.co.uk> (1994-10-15):
# A relative in Tallinn confirms the accuracy of the data for 1989 onwards
# [through 1994] and gives the legal authority for it,
# a regulation of the Government of Estonia, No. 111 of 1989....
#
# From Peter Ilieve <peter@aldie.co.uk> (1996-10-28):
# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
# but a relative confirms that Estonia still switches at 02:00s, writing:]
# ``I do not [know] exactly but there are some little different
# (confusing) rules for International Air and Railway Transport Schedules
# conversion in Sunday connected with end of summer time in Estonia....
# A discussion is running about the summer time efficiency and effect on
# human physiology.  It seems that Estonia maybe will not change to
# summer time next spring.''

# From Peter Ilieve <peter@aldie.co.uk> (1998-11-04), heavily edited:
# <a href="http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390">
# The 1998-09-22 Estonian time law
# </a>
# refers to the Eighth Directive and cites the association agreement between
# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120).
#
# I also asked [my relative] whether they use any standard abbreviation
# for their standard and summer times. He says no, they use "suveaeg"
# (summer time) and "talveaeg" (winter time).

# From <a href="http://www.baltictimes.com/">The Baltic Times</a> (1999-09-09)
# via Steffen Thorsen:
# This year will mark the last time Estonia shifts to summer time,
# a council of the ruling coalition announced Sept. 6....
# But what this could mean for Estonia's chances of joining the European
# Union are still unclear.  In 1994, the EU declared summer time compulsory
# for all member states until 2001.  Brussels has yet to decide what to do
# after that.

# From Mart Oruaas (2000-01-29):
# Regulation no. 301 (1999-10-12) obsoletes previous regulation
# no. 206 (1998-09-22) and thus sticks Estonia to +02:00 GMT for all
# the year round.  The regulation is effective 1999-11-01.

# Iceland
#
# From Adam David <adam@veda.is> (1993-11-06):
# The name of the timezone in Iceland for system / mail / news purposes is GMT.
#
# (1993-12-05):
# This material is paraphrased from the 1988 edition of the University of
# Iceland Almanak.
#
# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
# behind GMT. Previously, local mean solar time was used in different parts
# of Iceland, the almanak had been based on Reykjavik mean solar time which
# was 1 hour and 28 minutes behind GMT.
#
# "first day of winter" referred to [below] means the first day of the 26 weeks
# of winter, according to the old icelandic calendar that dates back to the
# time the norsemen first settled Iceland.  The first day of winter is always
# Saturday, but is not dependent on the Julian or Gregorian calendars.
#
# (1993-12-10):
# I have a reference from the Oxford Icelandic-English dictionary for the
# beginning of winter, which ties it to the ecclesiastical calendar (and thus
# to the julian/gregorian calendar) over the period in question.
#	the winter begins on the Saturday next before St. Luke's day
#	(old style), or on St. Luke's day, if a Saturday.
# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
# might be a reference to the Julian calendar as opposed to Gregorian, or it
# might mean something else (???).
#
# From Paul Eggert <eggert@twinsun.com> (1999-10-29):
# The Iceland Almanak, Shanks and Whitman disagree on many points.
# We go with the Almanak, except for one claim from Shanks, namely that
# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

# Italy
#
# From Paul Eggert (2001-03-06):
# Sicily and Sardinia each had their own time zones from 1866 to 1893,

# During World War II, German-controlled Italy used German time.
# But these events all occurred before the 1970 cutoff,
# so record only the time in Rome.

# Latvia

# From Liene Kanepe <Liene_Kanepe@lm.gov.lv> (1998-09-17):

# I asked about this matter Scientific Secretary of the Institute of Astronomy
# of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the
# correct data in juridical acts and I found some juridical documents about
# changes in the counting of time in Latvia from 1981....
#
# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24
# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
# the hands of the clock 1 hour forward on 1 April at 00:00 (GMT 31 March 21:00)
# and 1 hour backward on the 1 October at 00:00 (GMT 30 September 20:00).
#
# Act No.592 of the Council of Ministers of Latvian SSR of 1984-09-24 ...
# according to the Act No.967 of the Council of Ministers of USSR of 1984-09-13
# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
# the hands of the clock 1 hour forward on the last Sunday of March at 02:00
# (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of
# September at 03:00 (GMT 23:00 on the previous day).
#
# Act No.81 of the Council of Ministers of Latvian SSR of 1989-03-22 ...
# according to the Act No.227 of the Council of Ministers of USSR of 1989-03-14
# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR,
# Estonian SSR and Kaliningrad region of Russian Federation all year round the
# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia
# transition to summer time is performed on the last Sunday of March at 02:00
# (GMT 00:00), turning the hands of the clock 1 hour forward.  The end of
# daylight saving time is performed on the last Sunday of September at 03:00
# (GMT 00:00), turning the hands of the clock 1 hour backward. Exception is
# 1989-03-26, when we must not turn the hands of the clock....
#
# The Regulations of the Cabinet of Ministers of the Republic of Latvia of
# 1997-01-21 on transition to Summer time ... established the same order of
# daylight savings time settings as in the States of the European Union.

# From Andrei Ivanov (2000-03-06):
# This year Latvia will not switch to Daylight Savings Time (as specified in
# <a href="http://www.lv-laiks.lv/wwwraksti/2000/071072/vd4.htm">
# The Regulations of the Cabinet of Ministers of the Rep. of Latvia of
# 29-Feb-2000 (#79)</a>, in Latvian for subscribers only).

# <a href="http://www.rferl.org/newsline/2001/01/3-CEE/cee-030101.html">
# From RFE/RL Newsline (2001-01-03), noted after a heads-up by Rives McDow:
# </a>
# The Latvian government on 2 January decided that the country will
# institute daylight-saving time this spring, LETA reported.
# Last February the three Baltic states decided not to turn back their
# clocks one hour in the spring....
# Minister of Economy Aigars Kalvitis noted that Latvia had too few
# daylight hours and thus decided to comply with a draft European
# Commission directive that provides for instituting daylight-saving
# time in EU countries between 2002 and 2006. The Latvian government
# urged Lithuania and Estonia to adopt a similar time policy, but it
# appears that they will not do so....

# Lithuania

# From Paul Eggert (1996-11-22):
# IATA SSIM (1992/1996) says Lithuania uses W-Eur rules, but since it is
# known to be wrong about Estonia and Latvia, assume it's wrong here too.

# From Marius Gedminas <mgedmin@pub.osf.lt> (1998-08-07):
# I would like to inform that in this year Lithuanian time zone
# (Europe/Vilnius) was changed.

# From <a href="http://www.elta.lt/">ELTA</a> No. 972 (2582) (1999-09-29),
# via Steffen Thorsen:
# Lithuania has shifted back to the second time zone (GMT plus two hours)
# to be valid here starting from October 31,
# as decided by the national government on Wednesday....
# The Lithuanian government also announced plans to consider a
# motion to give up shifting to summer time in spring, as it was
# already done by Estonia.

# From the <a href="http://www.tourism.lt/informa/ff.htm">
# Fact File, Lithuanian State Department of Tourism
# </a> (2000-03-27): Local time is GMT+2 hours ..., no daylight saving.

# Moldova

# From Paul Eggert (2001-02-11):
# A previous version of this database followed Shanks, who writes that
# Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
# However, this is most likely an error, as Moldova declared independence
# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
# In early 1992 there was large-scale interethnic violence in the area
# and it's possible that some Russophones continued to observe Moscow time.
# But moldavizolit@tirastel.md and mk@tirastel.md separately reported via
# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.
# The Tiraspol entry has therefore been removed for now.

# Martin Bruckmann <martin@ua.pt> (1996-02-29) reports via Peter Ilieve

# IATA SSIM (1991-09) reports several 1991-09 and 1992-09 transitions

# harmonized with the EU), and that they stayed +0:00 that winter.

# Russia

# From Paul Eggert <eggert@twinsun.com> (1999-11-12):
# Except for Moscow after 1919-07-01, I invented the time zone abbreviations.
# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
# are from Andrey A. Chernov.  The rest is from Shanks, except we follow
# Chernov's report that 1992 DST transitions were Sat 23:00, not Sun 02:00s.
#
# From Andrey A. Chernov <ache@nagual.ru> (1996-10-04):
# `MSK' and `MSD' were born and used initially on Moscow computers with
# Unix-like OSes by several developer groups (e.g. Demos group, Kiae group)....
# The next step was the UUCP network, the Relcom predecessor
# (used mainly for mail), and MSK/MSD was actively used there.
#
# From Chris Carrier <72157.3334@CompuServe.COM> (1996-10-30):
# According to a friend of mine who rode the Trans-Siberian Railroad from
# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
# still follows Moscow time, no matter where in Russia it is located.
#
# For Grozny, Chechnya, we have the following story from
# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
# News--often false--is spread by word of mouth.  A rumor that it was
# time to move the clocks back put this whole city out of sync with
# the rest of Russia for two weeks--even soldiers stationed here began
# enforcing curfew at the wrong time.

# One source shows that Bulgaria, Cyprus, Finland, and Greece observe DST from
# the last Sunday in March to the last Sunday in September in 1986.
# The source shows Romania changing a day later than everybody else.
#
# According to Bernard Sieloff's source, Poland is in the MET time zone but
# uses the WE DST rules.  The Western USSR uses EET+1 and ME DST rules.
# Bernard Sieloff's source claims Romania switches on the same day, but at
# 00:00 standard time (i.e., 01:00 DST).  It also claims that Turkey
# switches on the same day, but switches on at 01:00 standard time
# and off at 00:00 standard time (i.e., 01:00 DST)

#
# ...the European time rules are...standardized since 1981, when
# most European coun[tr]ies started DST.  Before that year, only
# a few countries (UK, France, Italy) had DST, each according
# to own national rules.  In 1981, however, DST started on
# 'Apr firstSun', and not on 'Mar lastSun' as in the following
# years...
# But also since 1981 there are some more national exceptions
# than listed in 'europe': Switzerland, for example, joined DST
# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
# lastSun' in 1981---I don't know how they handle now.
#
# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
# Soviet Union (as far as I know).

#
# The information from Tom Hofmann is (as far as I know) not entirely correct.
# After a request from chongo at amdahl I tried to retrieve all information
# about DST in Europe.  I was able to find all from about 1969.
#
# ...standardization on DST in Europe started in about 1977 with switches on
# first Sunday in April and last Sunday in September...
# In 1981 UK joined Europe insofar that
# the starting day for both shifted to last Sunday in March.  And from 1982
# the whole of Europe used DST, with switch dates April 1 and October 1 in
# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
# dates...
#
# It should also be remembered that time-zones are not constants; e.g.
# Portugal switched in 1976 from MET (or CET) to WET with DST...
# Note also that though there were rules for switch dates not
# all countries abided to these dates, and many individual deviations
# occurred, though not since 1982 I believe.  Another note: it is always
# assumed that DST is 1 hour ahead of normal time, this need not be the
# case; at least in the Netherlands there have been times when DST was 2 hours
# in advance of normal time.
