104# Britain (United Kingdom) and Ireland (Eire)
105
106# From Peter Ilieve (1994-07-06):
107#
108# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
109# historical vistas along the Thames in west London. There was a photo
110# and a sketch map showing some of the sightlines involved. One paragraph
111# of the text said:
112#
113# 'An old stone obelisk marking a forgotten terrestrial meridian stands
114# beside the river at Kew. In the 18th century, before time and longitude
115# was standardised by the Royal Observatory in Greenwich, scholars observed
116# this stone and the movement of stars from Kew Observatory nearby. They
117# made their calculations and set the time for the Horse Guards and Parliament,
118# but now the stone is obscured by scrubwood and can only be seen by walking
119# along the towpath within a few yards of it.'
120#
121# I have a one inch to one mile map of London and my estimate of the stone's
122# position is 51 degrees 28' 30" N, 0 degrees 18' 45" W. The longitude should
123# be within about +-2". The Ordnance Survey grid reference is TQ172761.
124#
125# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
126
127# From Paul Eggert (1993-11-18):
128#
129# Howse writes that Britain was the first country to use standard time.
130# The railways cared most about the inconsistencies of local mean time,
131# and it was they who forced a uniform time on the country.
132# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
133# and was popularized by Abraham Follett Osler (1808-1903).
134# The first railway to adopt London time was the Great Western Railway
135# in November 1840; other railways followed suit, and by 1847 most
136# (though not all) railways used London time.  On 1847-09-22 the
137# Railway Clearing House, an industry standards body, recommended that GMT be
138# adopted at all stations as soon as the General Post Office permitted it.
139# The transition occurred on 12-01 for the L&NW, the Caledonian,
140# and presumably other railways; the January 1848 Bradshaw's lists many
141# railways as using GMT.  By 1855 the vast majority of public
142# clocks in Britain were set to GMT (though some, like the great clock
143# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
144# one for local time and one for GMT).  The last major holdout was the legal
145# system, which stubbornly stuck to local time for many years, leading
146# to oddities like polls opening at 08:13 and closing at 16:13.
147# The legal system finally switched to GMT when the Statutes (Definition
148# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
149#
150# In the tables below, we condense this complicated story into a single
151# transition date for London, namely 1847-12-01.  We don't know as much
152# about Dublin, so we use 1880-08-02, the legal transition time.
153
154# From Paul Eggert (2014-07-19):
155# The ancients had no need for daylight saving, as they kept time
156# informally or via hours whose length depended on the time of year.
157# Daylight saving time in its modern sense was invented by the
158# New Zealand entomologist George Vernon Hudson (1867-1946),
159# whose day job as a postal clerk led him to value
160# after-hours daylight in which to pursue his research.
161# In 1895 he presented a paper to the Wellington Philosophical Society
162# that proposed a two-hour daylight-saving shift.  See:
163# Hudson GV. On seasonal time-adjustment in countries south of lat. 30 deg.
164# Transactions and Proceedings of the New Zealand Institute. 1895;28:734
165# http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
166# Although some interest was expressed in New Zealand, his proposal
167# did not find its way into law and eventually it was almost forgotten.
168#
169# In England, DST was independently reinvented by William Willett (1857-1915),
170# a London builder and member of the Royal Astronomical Society
171# who circulated a pamphlet "The Waste of Daylight" (1907)
172# that proposed advancing clocks 20 minutes on each of four Sundays in April,
173# and retarding them by the same amount on four Sundays in September.
174# A bill was drafted in 1909 and introduced in Parliament several times,
175# but it met with ridicule and opposition, especially from farming interests.
176# Later editions of the pamphlet proposed one-hour summer time, and
177# it was eventually adopted as a wartime measure in 1916.
178# See: Summer Time Arrives Early, The Times (2000-05-18).
179# A monument to Willett was unveiled on 1927-05-21, in an open space in
180# a 45-acre wood near Chislehurst, Kent that was purchased by popular
181# subscription and open to the public.  On the south face of the monolith,
182# designed by G. W. Miller, is the William Willett Memorial Sundial,
183# which is permanently set to Summer Time.
184
185# From Winston Churchill (1934-04-28):
186# It is one of the paradoxes of history that we should owe the boon of
187# summer time, which gives every year to the people of this country
188# between 160 and 170 hours more daylight leisure, to a war which
189# plunged Europe into darkness for four years, and shook the
190# foundations of civilization throughout the world.

194
195# From Paul Eggert (2015-08-08):
196# The OED Supplement says that the English originally said "Daylight Saving"
197# when they were debating the adoption of DST in 1908; but by 1916 this
198# term appears only in quotes taken from DST's opponents, whereas the
199# proponents (who eventually won the argument) are quoted as using "Summer".
200# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see:
201# Viscount Samuel. Leisure in a Democracy. Cambridge University Press
202# ISBN 978-1-107-49471-8 (1949, reissued 2015), p 8.
203
204# From Arthur David Olson (1989-01-19):
205# A source at the British Information Office in New York avers that it's
206# known as "British" Summer Time in all parts of the United Kingdom.

208# Date: 4 Jan 89 08:57:25 GMT (Wed)
209# From: Jonathan Leffler
210# [British Summer Time] is fixed annually by Act of Parliament.
211# If you can predict what Parliament will do, you should be in
212# politics making a fortune, not computing.
213
214# From Chris Carrier (1996-06-14):
215# I remember reading in various wartime issues of the London Times the
216# acronym BDST for British Double Summer Time.  Look for the published
217# time of sunrise and sunset in The Times, when BDST was in effect, and
218# if you find a zone reference it will say, "All times B.D.S.T."
219
220# From Joseph S. Myers (1999-09-02):
221# ... some military cables (WO 219/4100 - this is a copy from the
222# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
223# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
224
225# From Joseph S. Myers (2000-10-03):
226# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
227# Alexander Maxwell of the Home Office asking whether there was any
228# official designation; the reply of the 21st was that there wasn't
229# but he couldn't think of anything better than the "Double British
230# Summer Time" that the BBC had been using informally.

232# http://www.polyomino.org.uk/british-time/ho-19410421.png
233
234# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
235# [N]o official designation has as far as I know been adopted for the time
236# which is to be introduced in May....
237# I cannot think of anything better than "Double British Summer Time"
238# which could not be said to run counter to any official description.
239
240# From Paul Eggert (2000-10-02):
241# Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common
242# and follows the more usual convention of putting the location name first,
243# so we use 'BDST'.
244
245# Peter Ilieve (1998-04-19) described at length
246# the history of summer time legislation in the United Kingdom.
247# Since 1998 Joseph S. Myers has been updating
248# and extending this list, which can be found in
249# http://www.polyomino.org.uk/british-time/
250
251# From Joseph S. Myers (1998-01-06):
252#
253# The legal time in the UK outside of summer time is definitely GMT, not UTC;
254# see Lord Tanlaw's speech
255# http://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0
256# (Lords Hansard 11 June 1997 columns 964 to 976).
257
258# From Paul Eggert (2006-03-22):
259#
260# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
261#
262# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
263# are incorrect:
264#     * Wales did not switch from GMT to daylight saving time until
265#	1921 Apr 3, when they began to conform with the rest of Great Britain.
266# Actually, Wales was identical after 1880.
267#     * Eire had two transitions on 1916 Oct 1.
268# It actually just had one transition.
269#     * Northern Ireland used single daylight saving time throughout WW II.
270# Actually, it conformed to Britain.
271#     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
272# Actually, that date saw the usual switch to summer time.
273# Standard time was not changed until 1968-10-27 (the clocks didn't change).
274#
275# Here is another incorrect claim by Shanks & Pottenger:
276#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
277#	to daylight saving time until 1921 Apr 3, when they began to
278#	conform with Great Britain.
279# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
280#
281# The following claim by Shanks & Pottenger is possible though doubtful;
282# we'll ignore it for now.
283#     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
284#
285#
286# Whitman says Dublin Mean Time was -0:25:21, which is more precise than
287# Shanks & Pottenger.
288# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
289# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
290# to London.  For example:
291#
292#   "Timeball on the ballast office is down.  Dunsink time."
293#   -- James Joyce, Ulysses
294
295# "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time
296# was among various actions undertaken by the 'English' government that
297# would 'put the whole country into the SF (Sinn F��in) camp'.  She claimed
298# Irish 'public feeling (was) outraged by forcing of English time on us'."
299# -- Parsons M. Dublin lost its time zone - and 25 minutes - after 1916 Rising.

327# (Note that the time in the Republic of Ireland since 1968 has been defined

332# From Paul Eggert (1999-03-28):
333# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
334# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
335# (CT), equivalent to French civil time.
336# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
337# trains between Dollands Moor (the freight facility next door)
338# and Frethun run in CT.
339# My admittedly uninformed guess is that the terminal has two authorities,
340# the French concession operators and the British civil authorities,
341# and that the time depends on who you're talking to.
342# If, say, the British police were called to the station for some reason,
343# I would expect the official police report to use GMT/BST and not CET/CEST.
344# This is a borderline case, but for now let's stick to GMT/BST.
345
346# From an anonymous contributor (1996-06-02):
347# The law governing time in Ireland is under Statutory Instrument SI 395/94,

349# Under this directive, the Minister for Justice in Ireland makes appropriate

531# From Jesper N��rgaard Welen (2008-07-13):
532#
533# I found what is probably a typo of 2:00 which should perhaps be 2:00s
534# in the C-Eur rule from tz database version 2008d (this part was
535# corrected in version 2008d). The circumstantial evidence is simply the
536# tz database itself, as seen below:

555# It seems that Paris, Monaco, Rule France, Rule Belgium all agree on

557# countries that use C-Eur rules in September 1945, so the only items
558# affected are apparently these fictitious zones that translate acronyms

923# From Jesper N��rgaard Welen (2005-04-26):
924# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
925# [introducing standard time] was in effect from 1894-01-01....
926# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
927# confirms this, and states that the law was put forth 1893-03-29.
928#
929# The EU treaty with effect from 1973:
930# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
931#
932# This provoked a new law from 1974 to make possible summer time changes
933# in subsequent decrees with the law
934# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
935#
936# It seems however that no decree was set forward until 1980.  I have
937# not found any decree, but in another related law, the effecting DST
938# changes are stated explicitly to be from 1980-04-06 at 02:00 to
939# 1980-09-28 at 02:00.  If this is true, this differs slightly from
940# the EU rule in that DST runs to 02:00, not 03:00.  We don't know
941# when Denmark began using the EU rule correctly, but we have only
942# confirmation of the 1980-time, so I presume it was correct in 1981:
943# The law is about the management of the extra hour, concerning
944# working hours reported and effect on obligatory-rest rules (which
945# was suspended on that night):

947
948# From Jesper N��rgaard Welen (2005-06-11):
949# The Herning Folkeblad (1980-09-26) reported that the night between
950# Saturday and Sunday the clock is set back from three to two.
951
952# From Paul Eggert (2005-06-11):
953# Hence the "02:00" of the 1980 law refers to standard time, not
954# wall-clock time, and so the EU rules were in effect in 1980.

980# From Paul Eggert (2004-10-31):
981# During World War II, Germany maintained secret manned weather stations in
982# East Greenland and Franz Josef Land, but we don't know their time zones.
983# My source for this is Wilhelm Dege's book mentioned under Svalbard.
984#
985# From Paul Eggert (2006-03-22):
986# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
987# and left the EU on 1985-02-01.  It therefore should have been using EU
988# rules at least through 1984.  Shanks & Pottenger say Scoresbysund and Godth��b
989# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
990# rules since at least 1991.  Assume EU rules since 1980.
991
992# From Gwillim Law (2001-06-06), citing
993# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
994# and with translations corrected by Steffen Thorsen:
995#
996# Greenland has four local times, and the relation to UTC
997# is according to the following time line:
998#
999# The military zone near Thule	UTC-4
1000# Standard Greenland time	UTC-3
1001# Scoresbysund			UTC-1
1002# Danmarkshavn			UTC
1003#
1004# In the military area near Thule and in Danmarkshavn DST will not be
1005# introduced.
1006
1007# From Rives McDow (2001-11-01):
1008#
1009# I correspond regularly with the Dansk Polarcenter, and wrote them at
1010# the time to clarify the situation in Thule.  Unfortunately, I have
1011# not heard back from them regarding my recent letter.  [But I have
1012# info from earlier correspondence.]
1013#
1014# According to the center, a very small local time zone around Thule
1015# Air Base keeps the time according to UTC-4, implementing daylight
1016# savings using North America rules, changing the time at 02:00 local time....
1017#
1018# The east coast of Greenland north of the community of Scoresbysund
1019# uses UTC in the same way as in Iceland, year round, with no dst.
1020# There are just a few stations on this coast, including the
1021# Danmarkshavn ICAO weather station mentioned in your September 29th
1022# email.  The other stations are two sledge patrol stations in
1023# Mestersvig and Daneborg, the air force base at Station Nord, and the
1024# DPC research station at Zackenberg.
1025#
1026# Scoresbysund and two small villages nearby keep time UTC-1 and use
1027# the same daylight savings time period as in West Greenland (Godth��b).
1028#
1029# The rest of Greenland, including Godth��b (this area, although it
1030# includes central Greenland, is known as west Greenland), keeps time
1031# UTC-3, with daylight savings methods according to European rules.
1032#
1033# It is common procedure to use UTC 0 in the wilderness of East and
1034# North Greenland, because it is mainly Icelandic aircraft operators
1035# maintaining traffic in these areas.  However, the official status of
1036# this area is that it sticks with Godth��b time.  This area might be
1037# considered a dual time zone in some respects because of this.
1038
1039# From Rives McDow (2001-11-19):
1040# I heard back from someone stationed at Thule; the time change took place
1041# there at 2:00 AM.
1042
1043# From Paul Eggert (2006-03-22):
1044# From 1997 on the CIA map shows Danmarkshavn on GMT;
1045# the 1995 map as like Godth��b.
1046# For lack of better info, assume they were like Godth��b before 1996.
1047# startkart.no says Thule does not observe DST, but this is clearly an error,
1048# so go with Shanks & Pottenger for Thule transitions until this year.
1049# For 2007 on assume Thule will stay in sync with US DST rules.
1050
1051# From J William Piggott (2016-02-20):
1052# "Greenland north of the community of Scoresbysund" is officially named
1053# "National Park" by Executive Order:
1054# http://naalakkersuisut.gl/~/media/Nanoq/Files/Attached%20Files/Engelske-tekster/Legislation/Executive%20Order%20National%20Park.rtf

1082# From Paul Eggert (2016-03-18):
1083# The 1989 transition is from USSR act No. 227 (1989-03-14).
1084#
1085# From Peter Ilieve (1994-10-15):
1086# A relative in Tallinn confirms the accuracy of the data for 1989 onwards
1087# [through 1994] and gives the legal authority for it,
1088# a regulation of the Government of Estonia, No. 111 of 1989....
1089#
1090# From Peter Ilieve (1996-10-28):
1091# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
1092# but a relative confirms that Estonia still switches at 02:00s, writing:]
1093# "I do not [know] exactly but there are some little different
1094# (confusing) rules for International Air and Railway Transport Schedules
1095# conversion in Sunday connected with end of summer time in Estonia....
1096# A discussion is running about the summer time efficiency and effect on
1097# human physiology.  It seems that Estonia maybe will not change to
1098# summer time next spring."
1099
1100# From Peter Ilieve (1998-11-04), heavily edited:
1101# The 1998-09-22 Estonian time law
1102# http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390
1103# refers to the Eighth Directive and cites the association agreement between
1104# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22-27, 120).
1105#
1106# I also asked [my relative] whether they use any standard abbreviation
1107# for their standard and summer times. He says no, they use "suveaeg"
1108# (summer time) and "talveaeg" (winter time).
1109
1110# From The Baltic Times <http://www.baltictimes.com/> (1999-09-09)
1111# via Steffen Thorsen:
1112# This year will mark the last time Estonia shifts to summer time,
1113# a council of the ruling coalition announced Sept. 6....
1114# But what this could mean for Estonia's chances of joining the European
1115# Union are still unclear.  In 1994, the EU declared summer time compulsory
1116# for all member states until 2001.  Brussels has yet to decide what to do
1117# after that.
1118
1119# From Mart Oruaas (2000-01-29):
1120# Regulation No. 301 (1999-10-12) obsoletes previous regulation
1121# No. 206 (1998-09-22) and thus sticks Estonia to +02:00 GMT for all

1123
1124# From Toomas Soome (2002-02-21):

1152# From Janne Snabb (2010-07-15):
1153#
1154# I noticed that the Finland data is not accurate for years 1981 and 1982.

1310# says that Bersarin issued an order to use Moscow time on May 20.
1311# However, Moscow did not observe daylight saving in 1945, so
1312# this was equivalent to UT +03, not +04.

1436# Iceland
1437#
1438# From Adam David (1993-11-06):
1439# The name of the timezone in Iceland for system / mail / news purposes is GMT.
1440#
1441# (1993-12-05):
1442# This material is paraphrased from the 1988 edition of the University of
1443# Iceland Almanak.
1444#
1445# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1446# behind GMT. Previously, local mean solar time was used in different parts
1447# of Iceland, the almanak had been based on Reykjavik mean solar time which
1448# was 1 hour and 28 minutes behind GMT.
1449#
1450# "first day of winter" referred to [below] means the first day of the 26 weeks
1451# of winter, according to the old icelandic calendar that dates back to the
1452# time the norsemen first settled Iceland.  The first day of winter is always
1453# Saturday, but is not dependent on the Julian or Gregorian calendars.
1454#
1455# (1993-12-10):
1456# I have a reference from the Oxford Icelandic-English dictionary for the
1457# beginning of winter, which ties it to the ecclesiastical calendar (and thus
1458# to the julian/gregorian calendar) over the period in question.
1459#	the winter begins on the Saturday next before St. Luke's day
1460#	(old style), or on St. Luke's day, if a Saturday.
1461# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1462# might be a reference to the Julian calendar as opposed to Gregorian, or it
1463# might mean something else (???).

1495#
1496# From Paul Eggert (2001-03-06):
1497# Sicily and Sardinia each had their own time zones from 1866 to 1893,
1498# called Palermo Time (+00:53:28) and Cagliari Time (+00:36:32).
1499# During World War II, German-controlled Italy used German time.
1500# But these events all occurred before the 1970 cutoff,

1508#
1509# From Pierpaolo Bernardi (2016-10-20):

1802# ... says that since 1990-05-06 on the territory of the Moldavian SSR
1803# time would be calculated as the standard time of the second time belt
1804# plus one hour of the "summer" time. To implement that clocks would be

1806# time would be cancelled last Sunday of September at 3:00 and
1807# reintroduced last Sunday of March at 2:00.
1808
1809# From Paul Eggert (2006-03-22):
1810# A previous version of this database followed Shanks & Pottenger, who write
1811# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1812# However, this is most likely an error, as Moldova declared independence
1813# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1814# In early 1992 there was large-scale interethnic violence in the area
1815# and it's possible that some Russophones continued to observe Moscow time.
1816# But [two people] separately reported via

1818# The Tiraspol entry has therefore been removed for now.

1888# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
1889# but for other purposes the Netherlands used Amsterdam mean time.
1890
1891# However, Robert H. van Gent writes (2001-04-01):
1892# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
1893# Amsterdam mean time) onwards, the whole of the Netherlands (including
1894# the Dutch railways) was required by law to observe Amsterdam mean time
1895# (19 minutes 32.13 seconds ahead of GMT). This had already been the
1896# common practice (except for the railways) for many decades but it was
1897# not until 1909 when the Dutch government finally defined this by law.
1898# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
1899# was generally known as Dutch Time ("Nederlandse Tijd").
1900#
1901# (2001-04-08):
1902# 1892-05-01 was the date when the Dutch railways were by law required to
1903# observe GMT while the remainder of the Netherlands adhered to the common
1904# practice of following Amsterdam mean time.
1905#
1906# (2001-04-09):
1907# In 1835 the authorities of the province of North Holland requested the
1908# municipal authorities of the towns and cities in the province to observe
1909# Amsterdam mean time but I do not know in how many cases this request was
1910# actually followed.
1911#
1912# From 1852 onwards the Dutch telegraph offices were by law required to
1913# observe Amsterdam mean time. As the time signals from the observatory of
1914# Leiden were also distributed by the telegraph system, I assume that most
1915# places linked up with the telegraph (and railway) system automatically
1916# adopted Amsterdam mean time.
1917#
1918# Although the early Dutch railway companies initially observed a variety
1919# of times, most of them had adopted Amsterdam mean time by 1858 but it
1920# was not until 1866 when they were all required by law to observe
1921# Amsterdam mean time.

1978# Svalbard & Jan Mayen
1979
1980# From Steffen Thorsen (2001-05-01):
1981# Although I could not find it explicitly, it seems that Jan Mayen and
1982# Svalbard have been using the same time as Norway at least since the
1983# time they were declared as parts of Norway.  Svalbard was declared
1984# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
1985# Mayen by law of 1930-02-27 no 2, section 2. (From
1986# <http://www.lovdata.no/all/nl-19250717-011.html> and
1987# <http://www.lovdata.no/all/nl-19300227-002.html>).  The law/regulation
1988# for normal/standard time in Norway is from 1894-06-29 no 1 (came
1989# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
1990# part of this law since 1925/1930. (From
1991# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
1992# able to find if Jan Mayen used a different time zone (e.g. -0100)
1993# before 1930. Jan Mayen has only been "inhabited" since 1921 by
1994# Norwegian meteorologists and maybe used the same time as Norway ever
1995# since 1921.  Svalbard (Arctic/Longyearbyen) has been inhabited since
1996# before 1895, and therefore probably changed the local time somewhere
1997# between 1895 and 1925 (inclusive).
1998
1999# From Paul Eggert (2013-09-04):
2000#
2001# Actually, Jan Mayen was never occupied by Germany during World War II,
2002# so it must have diverged from Oslo time during the war, as Oslo was
2003# keeping Berlin time.
2004#
2005# <http://home.no.net/janmayen/history.htm> says that the meteorologists
2006# burned down their station in 1940 and left the island, but returned in
2007# 1941 with a small Norwegian garrison and continued operations despite
2008# frequent air attacks from Germans.  In 1943 the Americans established a
2009# radiolocating station on the island, called "Atlantic City".  Possibly
2010# the UT offset changed during the war, but I think it unlikely that
2011# Jan Mayen used German daylight-saving rules.
2012#
2013# Svalbard is more complicated, as it was raided in August 1941 by an
2014# Allied party that evacuated the civilian population to England (says
2015# <http://www.bartleby.com/65/sv/Svalbard.html>).  The Svalbard FAQ
2016# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
2017# expelled on 1942-05-14.  However, small parties of Germans did return,
2018# and according to Wilhelm Dege's book "War North of 80" (1954)
2019# http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html
2020# the German armed forces at the Svalbard weather station code-named
2021# Haudegen did not surrender to the Allies until September 1945.
2022#
2023# All these events predate our cutoff date of 1970, so use Europe/Oslo
2024# for these regions.

2073# Portugal
2074#
2075# From Paul Eggert (2014-08-11), after a heads-up from Stephen Colebourne:
2076# According to a Portuguese decree (1911-05-26)
2077# http://dre.pt/pdf1sdip/1911/05/12500/23132313.pdf
2078# Lisbon was at -0:36:44.68, but switched to GMT on 1912-01-01 at 00:00.
2079# Round the old offset to -0:36:45.  This agrees with Willett but disagrees
2080# with Shanks, who says the transition occurred on 1911-05-24 at 00:00 for
2081# Europe/Lisbon, Atlantic/Azores, and Atlantic/Madeira.
2082#
2083# From Rui Pedro Salgueiro (1992-11-12):
2084# Portugal has recently (September, 27) changed timezone
2085# (from WET to MET or CET) to harmonize with EEC.
2086#
2087# Martin Bruckmann (1996-02-29) reports via Peter Ilieve
2088# that Portugal is reverting to 0:00 by not moving its clocks this spring.
2089# The new Prime Minister was fed up with getting up in the dark in the winter.
2090#
2091# From Paul Eggert (1996-11-12):
2092# IATA SSIM (1991-09) reports several 1991-09 and 1992-09 transitions
2093# at 02:00u, not 01:00u.  Assume that these are typos.
2094# IATA SSIM (1991/1992) reports that the Azores were at -1:00.
2095# IATA SSIM (1993-02) says +0:00; later issues (through 1996-09) say -1:00.
2096# Guess that the Azores changed to EU rules in 1992 (since that's when Portugal
2097# harmonized with the EU), and that they stayed +0:00 that winter.

2295# But now it is some months since Novosibirsk is 3 hours ahead of Moscow!
2296# I do not know why they have decided to make this change;
2297# as far as I remember it was done exactly during winter->summer switching

2300# From Andrey A. Chernov (1996-10-04):
2301# 'MSK' and 'MSD' were born and used initially on Moscow computers with
2302# UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
2303# The next step was the UUCP network, the Relcom predecessor

2311# For Grozny, Chechnya, we have the following story from
2312# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
2313# News - often false - is spread by word of mouth.  A rumor that it was
2314# time to move the clocks back put this whole city out of sync with
2315# the rest of Russia for two weeks - even soldiers stationed here began
2316# enforcing curfew at the wrong time.
2317#
2318# From Gwillim Law (2001-06-05):
2319# There's considerable evidence that Sakhalin Island used to be in
2320# UTC+11, and has changed to UTC+10, in this decade.  I start with the
2321# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
2322# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
2323# since September 1997....  Although the Kuril Islands are

2436# same Nauka i Zhizn articles converted to the text form (but misses
2437# time belt changes map).
2438#
2439# The second Nauka i Zhizn article says that in addition to
2440# introduction of summer time on 1981-04-01 there are some time belt
2441# border changes on 1981-10-01, mostly affecting Nenets Autonomous
2442# Okrug, Krasnoyarsk Krai, Yakutia, Magadan Oblast and Chukotka
2443# according to the provided map (colored one).  In addition to that
2444# "time violators" (regions which were not using rules of the time
2445# belts in which they were located) would not be moving off the DST on
2446# 1981-10-01 to restore the decree time usage.  (Komi ASSR was

2449# is also provided.
2450#
2451# The article from Trud says that 1981-10-01 changes caused problems
2452# and some territories would be moved to pre-1981-10-01 time by not
2453# moving to summer time on 1982-04-01.  Namely: Dagestan,
2454# Kabardino-Balkar, Kalmyk, Komi, Mari, Mordovian, North Ossetian,

2467# Udmurtia to the list of affected territories and lists Khatangsky

3288# From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
3289#
3290# The law "Svensk f��rfattningssamling 1878, no 14" about standard time in 1879:
3291# From the beginning of 1879 (that is 01-01 00:00) the time for all
3292# places in the country is "the mean solar time for the meridian at
3293# three degrees, or twelve minutes of time, to the west of the
3294# meridian of the Observatory of Stockholm".  The law is dated 1878-05-31.
3295#
3296# The observatory at that time had the meridian 18 degrees 03' 30"
3297# eastern longitude = 01:12:14 in time.  Less 12 minutes gives the
3298# national standard time as 01:00:14 ahead of GMT....
3299#
3300# About the beginning of CET in Sweden. The lawtext ("Svensk
3301# f��rfattningssamling 1899, no 44") states, that "from the beginning
3302# of 1900... ... the same as the mean solar time for the meridian at
3303# the distance of one hour of time from the meridian of the English
3304# observatory at Greenwich, or at 12 minutes 14 seconds to the west
3305# from the meridian of the Observatory of Stockholm". The law is dated
3306# 1899-06-16.  In short: At 1900-01-01 00:00:00 the new standard time
3307# in Sweden is 01:00:00 ahead of GMT.
3308#
3309# 1916: The lawtext ("Svensk f��rfattningssamling 1916, no 124") states
3310# that "1916-05-15 is considered to begin one hour earlier". It is
3311# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
3312# Further the law says, that "1916-09-30 is considered to end one hour later".
3313#
3314# The laws regulating [DST] are available on the site of the Swedish
3315# Parliament beginning with 1985 - the laws regulating 1980/1984 are
3316# not available on the site (to my knowledge they are only available
3317# in Swedish): <http://www.riksdagen.se/english/work/sfst.asp> (type

3320#
3321# (2001-05-13):
3322#
3323# I have now found a newspaper stating that at 1916-10-01 01:00
3324# summertime the church-clocks etc were set back one hour to show
3325# 1916-10-01 00:00 standard time.  The article also reports that some
3326# people thought the switch to standard time would take place already
3327# at 1916-10-01 00:00 summer time, but they had to wait for another
3328# hour before the event took place.

3353# From Alois Treindl (2008-12-17):
3354# I have researched the DST usage in Switzerland during the 1940ies.
3355#
3356# As I wrote in an earlier message, I suspected the current tzdata values
3357# to be wrong. This is now verified.
3358#
3359# I have found copies of the original ruling by the Swiss Federal
3360# government, in 'Eidgen��ssische Gesetzessammlung 1941 and 1942' (Swiss
3361# federal law collection)...
3362#
3363# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
3364# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
3365#
3366# DST began on Monday, 4 May 1942 at 01:00 am
3367# DST ended on Monday, 5 Oct 1942 at 02:00 am
3368#
3369# There was no DST in 1940, I have checked the law collection carefully.
3370# It is also indicated by the fact that the 1942 entry in the law
3371# collection points back to 1941 as a reference, but no reference to any
3372# other years are made.
3373#
3374# Newspaper articles I have read in the archives on 6 May 1941 reported
3375# about the introduction of DST (Sommerzeit in German) during the previous
3376# night as an absolute novelty, because this was the first time that such
3377# a thing had happened in Switzerland.
3378#
3379# I have also checked 1916, because one book source (Gabriel, Trait�� de
3380# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
3381# false, no official document could be found. Probably Gabriel got misled
3382# by references to Germany, which introduced DST in 1916 for the first time.
3383#
3384# The tzdata rules for Switzerland must be changed to:
3385# Rule  Swiss   1941    1942    -       May     Mon>=1  1:00    1:00    S
3386# Rule  Swiss   1941    1942    -       Oct     Mon>=1  2:00    0       -
3387#
3388# The 1940 rules must be deleted.
3389#
3390# One further detail for Switzerland, which is probably out of scope for
3391# most users of tzdata: The [Europe/Zurich zone] ...
3392# describes all of Switzerland correctly, with the exception of
3393# the Canton de Gen��ve (Geneva, Genf). Between 1848 and 1894 Geneva did not
3394# follow Bern Mean Time but kept its own local mean time.
3395# To represent this, an extra zone would be needed.
3396#
3397# From Alois Treindl (2013-09-11):
3398# The Federal regulations say
3399# http://www.admin.ch/opc/de/classified-compilation/20071096/index.html
3400# ... the meridian for Bern mean time ... is 7 degrees 26' 22.50".
3401# Expressed in time, it is 0h29m45.5s.
3402
3403# From Pierre-Yves Berger (2013-09-11):
3404# the "Circulaire du conseil f��d��ral" (December 11 1893)
3405# http://www.amtsdruckschriften.bar.admin.ch/viewOrigDoc.do?id=10071353
3406# clearly states that the [1894-06-01] change should be done at midnight
3407# but if no one is present after 11 at night, could be postponed until one
3408# hour before the beginning of service.
3409
3410# From Paul Eggert (2013-09-11):
3411# Round BMT to the nearest even second, 0:29:46.
3412#
3413# We can find no reliable source for Shanks's assertion that all of Switzerland
3414# except Geneva switched to Bern Mean Time at 00:00 on 1848-09-12.  This book:

3418#	ISBN 3-905311-68-2, OCLC 717570797.
3419#
3420# suggests that the transition was more gradual, and that the Swiss did not
3421# agree about civil time during the transition.  The timekeeping it gives the
3422# most detail for is postal and telegraph time: here, federal legislation (the
3423# "Bundesgesetz ��ber die Erstellung von elektrischen Telegraphen") passed on
3424# 1851-11-23, and an official implementation notice was published 1853-07-16
3425# (Bundesblatt 1853, Bd. II, S. 859).  On p 72 Messerli writes that in
3426# practice since July 1853 Bernese time was used in "all postal and telegraph
3427# offices in Switzerland from Geneva to St. Gallen and Basel to Chiasso"
3428# (Google translation).  For now, model this transition as occurring on
3429# 1853-07-16, though it probably occurred at some other date in Zurich, and
3430# legal civil time probably changed at still some other transition date.

3711# Bernard Sieloff's source claims Romania switches on the same day, but at

3720#
3721# ...the European time rules are...standardized since 1981, when
3722# most European countries started DST.  Before that year, only
3723# a few countries (UK, France, Italy) had DST, each according
3724# to own national rules.  In 1981, however, DST started on
3725# 'Apr firstSun', and not on 'Mar lastSun' as in the following
3726# years...
3727# But also since 1981 there are some more national exceptions
3728# than listed in 'europe': Switzerland, for example, joined DST
3729# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
3730# lastSun' in 1981 - I don't know how they handle now.
3731#
3732# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
3733# Soviet Union (as far as I know).

3742# ...
3743#
3744# The information from Tom Hofmann is (as far as I know) not entirely correct.
3745# After a request from chongo at amdahl I tried to retrieve all information
3746# about DST in Europe.  I was able to find all from about 1969.
3747#
3748# ...standardization on DST in Europe started in about 1977 with switches on
3749# first Sunday in April and last Sunday in September...
3750# In 1981 UK joined Europe insofar that
3751# the starting day for both shifted to last Sunday in March.  And from 1982
3752# the whole of Europe used DST, with switch dates April 1 and October 1 in
3753# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
3754# dates...
3755#
3756# It should also be remembered that time-zones are not constants; e.g.
3757# Portugal switched in 1976 from MET (or CET) to WET with DST...
3758# Note also that though there were rules for switch dates not
3759# all countries abided to these dates, and many individual deviations
3760# occurred, though not since 1982 I believe.  Another note: it is always
3761# assumed that DST is 1 hour ahead of normal time, this need not be the
3762# case; at least in the Netherlands there have been times when DST was 2 hours
3763# in advance of normal time.
