79# From Peter Ilieve <peter@memex.co.uk> (1994-07-06):
80#
81# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
82# historical vistas along the Thames in west London. There was a photo
83# and a sketch map showing some of the sightlines involved. One paragraph
84# of the text said:
85#
86# `An old stone obelisk marking a forgotten terrestrial meridian stands
87# beside the river at Kew. In the 18th century, before time and longitude
88# was standardised by the Royal Observatory in Greenwich, scholars observed
89# this stone and the movement of stars from Kew Observatory nearby. They
90# made their calculations and set the time for the Horse Guards and Parliament,
91# but now the stone is obscured by scrubwood and can only be seen by walking
92# along the towpath within a few yards of it.'
93#
94# I have a one inch to one mile map of London and my estimate of the stone's
95# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
96# be within about +-2". The Ordnance Survey grid reference is TQ172761.
97#
98# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
99
100# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
101#
102# Howse writes that Britain was the first country to use standard time.
103# The railways cared most about the inconsistencies of local mean time,
104# and it was they who forced a uniform time on the country.
105# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
106# and was popularized by Abraham Follett Osler (1808-1903).
107# The first railway to adopt London time was the Great Western Railway
108# in November 1840; other railways followed suit, and by 1847 most
109# (though not all) railways used London time. On 1847-09-22 the
110# Railway Clearing House, an industry standards body, recommended that GMT be
111# adopted at all stations as soon as the General Post Office permitted it.
112# The transition occurred on 12-01 for the L&NW, the Caledonian,
113# and presumably other railways; the January 1848 Bradshaw's lists many
114# railways as using GMT. By 1855 the vast majority of public
115# clocks in Britain were set to GMT (though some, like the great clock
116# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
117# one for local time and one for GMT). The last major holdout was the legal
118# system, which stubbornly stuck to local time for many years, leading
119# to oddities like polls opening at 08:13 and closing at 16:13.
120# The legal system finally switched to GMT when the Statutes (Definition
121# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
122#
123# In the tables below, we condense this complicated story into a single
124# transition date for London, namely 1847-12-01. We don't know as much
125# about Dublin, so we use 1880-08-02, the legal transition time.
126
127# From Paul Eggert (1999-01-30):
128# Summer Time was first seriously proposed by William Willett (1857-1915),
129# a London builder and member of the Royal Astronomical Society
130# who circulated a pamphlet ``The Waste of Daylight'' (1907)
131# that proposed advancing clocks 20 minutes on each of four Sundays in April,
132# and retarding them by the same amount on four Sundays in September.
133# A bill was drafted in 1909 and introduced in Parliament several times,
134# but it met with ridicule and opposition, especially from farming interests.
135# One-hour Summer Time was eventually adopted as a wartime measure in 1916.

213# Actually, Wales was identical after 1880.

215# It actually just had one transition.
216# * Northern Ireland used single daylight saving time throughout WW II.
217# Actually, it conformed to Britain.
218# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.

200# From Joseph S. Myers <jsm28@cam.ac.uk> (1998-01-06):
201#
202# The legal time in the UK outside of summer time is definitely GMT, not UTC;
203# see Lord Tanlaw's speech
204# <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn/lds97/text/70611-20.htm#70611-20_head0">

206# </a>.
207
208# From Paul Eggert (2000-02-17):
209#
210# For lack of other data, we'll follow Shanks for Eire in 1940-1948.
211#
212# Given Ilieve and Myers's data, the following claims by Shanks are incorrect:
213# * Wales did not switch from GMT to daylight saving time until
214# 1921 Apr 3, when they began to conform with the rest of Great Britain.
215# Actually, Wales was identical after 1880.
216# * Eire had two transitions on 1916 Oct 1.
217# It actually just had one transition.
218# * Northern Ireland used single daylight saving time throughout WW II.
219# Actually, it conformed to Britain.
220# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
221# Actually, that date saw the usual switch to summer time.
222# Standard time was not changed until 1968-10-27 (the clocks didn't change).
223#

222# Here is another incorrect claim by Shanks:

223# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
224# to daylight saving time until 1921 Apr 3, when they began to
225# conform with Great Britain.
226# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
227#
228# The following claim by Shanks is possible though doubtful;
229# we'll ignore it for now.
230# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
231#
232#
233# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
234
235# From Paul Eggert (1999-03-28):
236# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
237# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
238# (CT), equivalent to French civil time.
239# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
240# trains between Dollands Moor (the freight facility next door)
241# and Frethun run in CT.
242# My admittedly uninformed guess is that the terminal has two authorities,
243# the French concession operators and the British civil authorities,
244# and that the time depends on who you're talking to.
245# If, say, the British police were called to the station for some reason,
246# I would expect the official police report to use GMT/BST and not CET/CEST.
247# This is a borderline case, but for now let's stick to GMT/BST.

249# From an anonymous contributor (1996-06-02):
250# The law governing time in Ireland is under Statutory Instrument SI 395/94,
251# which gives force to European Union 7th Council Directive # 94/21/EC.
252# Under this directive, the Minister for Justice in Ireland makes appropriate
253# regulations. I spoke this morning with the Secretary of the Department of

991#
992# From Adam David <adam@veda.is> (1993-11-06):
993# The name of the timezone in Iceland for system / mail / news purposes is GMT.
994#
995# (1993-12-05):
996# This material is paraphrased from the 1988 edition of the University of
997# Iceland Almanak.
998#
999# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1000# behind GMT. Previously, local mean solar time was used in different parts
1001# of Iceland, the almanak had been based on Reykjavik mean solar time which
1002# was 1 hour and 28 minutes behind GMT.
1003#
1004# "first day of winter" referred to [below] means the first day of the 26 weeks
1005# of winter, according to the old icelandic calendar that dates back to the
1006# time the norsemen first settled Iceland. The first day of winter is always
1007# Saturday, but is not dependent on the Julian or Gregorian calendars.
1008#
1009# (1993-12-10):
1010# I have a reference from the Oxford Icelandic-English dictionary for the
1011# beginning of winter, which ties it to the ecclesiastical calendar (and thus
1012# to the julian/gregorian calendar) over the period in question.
1013# the winter begins on the Saturday next before St. Luke's day
1014# (old style), or on St. Luke's day, if a Saturday.
1015# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1016# might be a reference to the Julian calendar as opposed to Gregorian, or it
1017# might mean something else (???).
1018#
1019# From Paul Eggert <eggert@twinsun.com> (1999-10-29):
1020# The Iceland Almanak, Shanks and Whitman disagree on many points.
1021# We go with the Almanak, except for one claim from Shanks, namely that
1022# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

1018# Iceland
1019#
1020# From Adam David <adam@veda.is> (1993-11-06):
1021# The name of the timezone in Iceland for system / mail / news purposes is GMT.
1022#
1023# (1993-12-05):
1024# This material is paraphrased from the 1988 edition of the University of
1025# Iceland Almanak.
1026#
1027# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1028# behind GMT. Previously, local mean solar time was used in different parts
1029# of Iceland, the almanak had been based on Reykjavik mean solar time which
1030# was 1 hour and 28 minutes behind GMT.
1031#
1032# "first day of winter" referred to [below] means the first day of the 26 weeks
1033# of winter, according to the old icelandic calendar that dates back to the
1034# time the norsemen first settled Iceland. The first day of winter is always
1035# Saturday, but is not dependent on the Julian or Gregorian calendars.
1036#
1037# (1993-12-10):
1038# I have a reference from the Oxford Icelandic-English dictionary for the
1039# beginning of winter, which ties it to the ecclesiastical calendar (and thus
1040# to the julian/gregorian calendar) over the period in question.
1041# the winter begins on the Saturday next before St. Luke's day
1042# (old style), or on St. Luke's day, if a Saturday.
1043# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1044# might be a reference to the Julian calendar as opposed to Gregorian, or it
1045# might mean something else (???).
1046#
1047# From Paul Eggert <eggert@twinsun.com> (1999-10-29):
1048# The Iceland Almanak, Shanks and Whitman disagree on many points.
1049# We go with the Almanak, except for one claim from Shanks, namely that
1050# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

1163# From Liene Kanepe <Liene_Kanepe@lm.gov.lv> (1998-09-17):
1164
1165# I asked about this matter Scientific Secretary of the Institute of Astronomy
1166# of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the
1167# correct data in juridical acts and I found some juridical documents about
1168# changes in the counting of time in Latvia from 1981....
1169#
1170# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
1171# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24
1172# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
1173# the hands of the clock 1 hour forward on 1 April at 00:00 (GMT 31 March 21:00)
1174# and 1 hour backward on the 1 October at 00:00 (GMT 30 September 20:00).
1175#
1176# Act No.592 of the Council of Ministers of Latvian SSR of 1984-09-24 ...
1177# according to the Act No.967 of the Council of Ministers of USSR of 1984-09-13
1178# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
1179# the hands of the clock 1 hour forward on the last Sunday of March at 02:00
1180# (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of
1181# September at 03:00 (GMT 23:00 on the previous day).
1182#
1183# Act No.81 of the Council of Ministers of Latvian SSR of 1989-03-22 ...
1184# according to the Act No.227 of the Council of Ministers of USSR of 1989-03-14
1185# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR,
1186# Estonian SSR and Kaliningrad region of Russian Federation all year round the
1187# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia
1188# transition to summer time is performed on the last Sunday of March at 02:00
1189# (GMT 00:00), turning the hands of the clock 1 hour forward. The end of
1190# daylight saving time is performed on the last Sunday of September at 03:00
1191# (GMT 00:00), turning the hands of the clock 1 hour backward. Exception is
1192# 1989-03-26, when we must not turn the hands of the clock....
1193#
1194# The Regulations of the Cabinet of Ministers of the Republic of Latvia of
1195# 1997-01-21 on transition to Summer time ... established the same order of
1196# daylight savings time settings as in the States of the European Union.
1197
1198# From Andrei Ivanov (2000-03-06):
1199# This year Latvia will not switch to Daylight Savings Time (as specified in
1200# <a href="http://www.lv-laiks.lv/wwwraksti/2000/071072/vd4.htm">
1201# The Regulations of the Cabinet of Ministers of the Rep. of Latvia of

1205# From RFE/RL Newsline (2001-01-03), noted after a heads-up by Rives McDow:
1206# </a>
1207# The Latvian government on 2 January decided that the country will
1208# institute daylight-saving time this spring, LETA reported.
1209# Last February the three Baltic states decided not to turn back their
1210# clocks one hour in the spring....
1211# Minister of Economy Aigars Kalvitis noted that Latvia had too few
1212# daylight hours and thus decided to comply with a draft European
1213# Commission directive that provides for instituting daylight-saving
1214# time in EU countries between 2002 and 2006. The Latvian government
1215# urged Lithuania and Estonia to adopt a similar time policy, but it
1216# appears that they will not do so....

1340# From Paul Eggert (2001-02-11):
1341# A previous version of this database followed Shanks, who writes that
1342# Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1343# However, this is most likely an error, as Moldova declared independence
1344# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1345# In early 1992 there was large-scale interethnic violence in the area
1346# and it's possible that some Russophones continued to observe Moscow time.
1347# But moldavizolit@tirastel.md and mk@tirastel.md separately reported via
1348# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.
1349# The Tiraspol entry has therefore been removed for now.

1930# to own national rules. In 1981, however, DST started on
1931# 'Apr firstSun', and not on 'Mar lastSun' as in the following
1932# years...
1933# But also since 1981 there are some more national exceptions
1934# than listed in 'europe': Switzerland, for example, joined DST
1935# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
1936# lastSun' in 1981---I don't know how they handle now.
1937#
1938# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
1939# Soviet Union (as far as I know).

1950# The information from Tom Hofmann is (as far as I know) not entirely correct.
1951# After a request from chongo at amdahl I tried to retrieve all information
1952# about DST in Europe. I was able to find all from about 1969.
1953#
1954# ...standardization on DST in Europe started in about 1977 with switches on
1955# first Sunday in April and last Sunday in September...
1956# In 1981 UK joined Europe insofar that
1957# the starting day for both shifted to last Sunday in March. And from 1982
1958# the whole of Europe used DST, with switch dates April 1 and October 1 in
1959# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
1960# dates...
1961#
1962# It should also be remembered that time-zones are not constants; e.g.
1963# Portugal switched in 1976 from MET (or CET) to WET with DST...
1964# Note also that though there were rules for switch dates not
1965# all countries abided to these dates, and many individual deviations
1966# occurred, though not since 1982 I believe. Another note: it is always
1967# assumed that DST is 1 hour ahead of normal time, this need not be the
1968# case; at least in the Netherlands there have been times when DST was 2 hours
1969# in advance of normal time.

1966# One source shows that Bulgaria, Cyprus, Finland, and Greece observe DST from
1967# the last Sunday in March to the last Sunday in September in 1986.
1968# The source shows Romania changing a day later than everybody else.

1970# According to Bernard Sieloff's source, Poland is in the MET time zone but
1971# uses the WE DST rules. The Western USSR uses EET+1 and ME DST rules.
1972# Bernard Sieloff's source claims Romania switches on the same day, but at
1973# 00:00 standard time (i.e., 01:00 DST). It also claims that Turkey
1974# switches on the same day, but switches on at 01:00 standard time
1975# and off at 00:00 standard time (i.e., 01:00 DST)

1983# ...the European time rules are...standardized since 1981, when
1984# most European coun[tr]ies started DST. Before that year, only
1985# a few countries (UK, France, Italy) had DST, each according
1986# to own national rules. In 1981, however, DST started on
1987# 'Apr firstSun', and not on 'Mar lastSun' as in the following
1988# years...
1989# But also since 1981 there are some more national exceptions
1990# than listed in 'europe': Switzerland, for example, joined DST
1991# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
1992# lastSun' in 1981---I don't know how they handle now.
1993#
1994# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
1995# Soviet Union (as far as I know).

2006# The information from Tom Hofmann is (as far as I know) not entirely correct.
2007# After a request from chongo at amdahl I tried to retrieve all information
2008# about DST in Europe. I was able to find all from about 1969.
2009#
2010# ...standardization on DST in Europe started in about 1977 with switches on
2011# first Sunday in April and last Sunday in September...
2012# In 1981 UK joined Europe insofar that
2013# the starting day for both shifted to last Sunday in March. And from 1982
2014# the whole of Europe used DST, with switch dates April 1 and October 1 in
2015# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
2016# dates...
2017#
2018# It should also be remembered that time-zones are not constants; e.g.
2019# Portugal switched in 1976 from MET (or CET) to WET with DST...
2020# Note also that though there were rules for switch dates not
2021# all countries abided to these dates, and many individual deviations
2022# occurred, though not since 1982 I believe. Another note: it is always
2023# assumed that DST is 1 hour ahead of normal time, this need not be the
2024# case; at least in the Netherlands there have been times when DST was 2 hours
2025# in advance of normal time.
