16# Gwillim Law writes that a good source
17# for recent time zone data is the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),
19# published semiannually.  Law sent in several helpful summaries
20# of the IATA's data after 1990.  Except where otherwise noted,
21# IATA SSIM is the source for entries after 1990.

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

195
196# From Paul Eggert (2015-08-08):
197# The OED Supplement says that the English originally said "Daylight Saving"
198# when they were debating the adoption of DST in 1908; but by 1916 this
199# term appears only in quotes taken from DST's opponents, whereas the
200# proponents (who eventually won the argument) are quoted as using "Summer".
201# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see:
202# Viscount Samuel. Leisure in a Democracy. Cambridge University Press
203# ISBN 978-1-107-49471-8 (1949, reissued 2015), p 8.
204
205# From Arthur David Olson (1989-01-19):
206# A source at the British Information Office in New York avers that it's
207# known as "British" Summer Time in all parts of the United Kingdom.
208
209# Date: 4 Jan 89 08:57:25 GMT (Wed)
210# From: Jonathan Leffler
211# [British Summer Time] is fixed annually by Act of Parliament.
212# If you can predict what Parliament will do, you should be in
213# politics making a fortune, not computing.
214
215# From Chris Carrier (1996-06-14):
216# I remember reading in various wartime issues of the London Times the
217# acronym BDST for British Double Summer Time.  Look for the published
218# time of sunrise and sunset in The Times, when BDST was in effect, and
219# if you find a zone reference it will say, "All times B.D.S.T."
220
221# From Joseph S. Myers (1999-09-02):
222# ... some military cables (WO 219/4100 - this is a copy from the
223# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
224# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
225
226# From Joseph S. Myers (2000-10-03):
227# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
228# Alexander Maxwell of the Home Office asking whether there was any
229# official designation; the reply of the 21st was that there wasn't
230# but he couldn't think of anything better than the "Double British
231# Summer Time" that the BBC had been using informally.

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

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

330# is GMT, rather than standard time being GMT with a period of summer time

332
333# From Paul Eggert (1999-03-28):
334# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
335# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
336# (CT), equivalent to French civil time.
337# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
338# trains between Dollands Moor (the freight facility next door)
339# and Frethun run in CT.
340# My admittedly uninformed guess is that the terminal has two authorities,
341# the French concession operators and the British civil authorities,
342# and that the time depends on who you're talking to.
343# If, say, the British police were called to the station for some reason,
344# I would expect the official police report to use GMT/BST and not CET/CEST.
345# This is a borderline case, but for now let's stick to GMT/BST.
346
347# From an anonymous contributor (1996-06-02):
348# The law governing time in Ireland is under Statutory Instrument SI 395/94,
349# which gives force to European Union 7th Council Directive No. 94/21/EC.
350# Under this directive, the Minister for Justice in Ireland makes appropriate

352# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is

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

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

663# From Markus Kuhn (1996-07-12):
664# The official German names ... are
665#
666#	Mitteleuropäische Zeit (MEZ)         = UTC+01:00
667#	Mitteleuropäische Sommerzeit (MESZ)  = UTC+02:00
668#
669# as defined in the German Time Act (Gesetz über die Zeitbestimmung (ZeitG),
670# 1978-07-25, Bundesgesetzblatt, Jahrgang 1978, Teil I, S. 1110-1111)....
671# I wrote ... to the German Federal Physical-Technical Institution

673#	Physikalisch-Technische Bundesanstalt (PTB)
674#	Laboratorium 4.41 "Zeiteinheit"
675#	Postfach 3345

677#	phone: +49 531 592-0
678#
679# ... I received today an answer letter from Dr. Peter Hetzel, head of the PTB
680# department for time and frequency transmission.  He explained that the
681# PTB translates MEZ and MESZ into English as

905# From Jesper Nørgaard Welen (2005-04-26):
906# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
907# [introducing standard time] was in effect from 1894-01-01....
908# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
909# confirms this, and states that the law was put forth 1893-03-29.
910#
911# The EU treaty with effect from 1973:
912# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
913#
914# This provoked a new law from 1974 to make possible summer time changes
915# in subsequent decrees with the law
916# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
917#
918# It seems however that no decree was set forward until 1980.  I have
919# not found any decree, but in another related law, the effecting DST
920# changes are stated explicitly to be from 1980-04-06 at 02:00 to
921# 1980-09-28 at 02:00.  If this is true, this differs slightly from
922# the EU rule in that DST runs to 02:00, not 03:00.  We don't know
923# when Denmark began using the EU rule correctly, but we have only
924# confirmation of the 1980-time, so I presume it was correct in 1981:
925# The law is about the management of the extra hour, concerning
926# working hours reported and effect on obligatory-rest rules (which
927# was suspended on that night):

930# From Jesper Nørgaard Welen (2005-06-11):
931# The Herning Folkeblad (1980-09-26) reported that the night between
932# Saturday and Sunday the clock is set back from three to two.
933
934# From Paul Eggert (2005-06-11):
935# Hence the "02:00" of the 1980 law refers to standard time, not
936# wall-clock time, and so the EU rules were in effect in 1980.

967# From Paul Eggert (2006-03-22):
968# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
969# and left the EU on 1985-02-01.  It therefore should have been using EU
970# rules at least through 1984.  Shanks & Pottenger say Scoresbysund and Godthåb
971# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
972# rules since at least 1991.  Assume EU rules since 1980.

974# From Gwillim Law (2001-06-06), citing
975# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
976# and with translations corrected by Steffen Thorsen:
977#
978# Greenland has four local times, and the relation to UTC
979# is according to the following time line:
980#
981# The military zone near Thule	UTC-4
982# Standard Greenland time	UTC-3
983# Scoresbysund			UTC-1
984# Danmarkshavn			UTC
985#
986# In the military area near Thule and in Danmarkshavn DST will not be
987# introduced.
988
989# From Rives McDow (2001-11-01):
990#
991# I correspond regularly with the Dansk Polarcenter, and wrote them at
992# the time to clarify the situation in Thule.  Unfortunately, I have
993# not heard back from them regarding my recent letter.  [But I have
994# info from earlier correspondence.]
995#
996# According to the center, a very small local time zone around Thule
997# Air Base keeps the time according to UTC-4, implementing daylight
998# savings using North America rules, changing the time at 02:00 local time....
999#
1000# The east coast of Greenland north of the community of Scoresbysund
1001# uses UTC in the same way as in Iceland, year round, with no dst.
1002# There are just a few stations on this coast, including the
1003# Danmarkshavn ICAO weather station mentioned in your September 29th
1004# email.  The other stations are two sledge patrol stations in
1005# Mestersvig and Daneborg, the air force base at Station Nord, and the
1006# DPC research station at Zackenberg.
1007#
1008# Scoresbysund and two small villages nearby keep time UTC-1 and use
1009# the same daylight savings time period as in West Greenland (Godthåb).
1010#
1011# The rest of Greenland, including Godthåb (this area, although it
1012# includes central Greenland, is known as west Greenland), keeps time
1013# UTC-3, with daylight savings methods according to European rules.
1014#
1015# It is common procedure to use UTC 0 in the wilderness of East and
1016# North Greenland, because it is mainly Icelandic aircraft operators
1017# maintaining traffic in these areas.  However, the official status of
1018# this area is that it sticks with Godthåb time.  This area might be
1019# considered a dual time zone in some respects because of this.
1020
1021# From Rives McDow (2001-11-19):
1022# I heard back from someone stationed at Thule; the time change took place
1023# there at 2:00 AM.
1024
1025# From Paul Eggert (2006-03-22):
1026# From 1997 on the CIA map shows Danmarkshavn on GMT;
1027# the 1995 map as like Godthåb.
1028# For lack of better info, assume they were like Godthåb before 1996.
1029# startkart.no says Thule does not observe DST, but this is clearly an error,
1030# so go with Shanks & Pottenger for Thule transitions until this year.
1031# For 2007 on assume Thule will stay in sync with US DST rules.
1032
1033# From J William Piggott (2016-02-20):
1034# "Greenland north of the community of Scoresbysund" is officially named
1035# "National Park" by Executive Order:

1066#
1067# From Peter Ilieve (1994-10-15):
1068# A relative in Tallinn confirms the accuracy of the data for 1989 onwards
1069# [through 1994] and gives the legal authority for it,
1070# a regulation of the Government of Estonia, No. 111 of 1989....
1071#
1072# From Peter Ilieve (1996-10-28):
1073# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
1074# but a relative confirms that Estonia still switches at 02:00s, writing:]
1075# "I do not [know] exactly but there are some little different
1076# (confusing) rules for International Air and Railway Transport Schedules
1077# conversion in Sunday connected with end of summer time in Estonia....
1078# A discussion is running about the summer time efficiency and effect on
1079# human physiology.  It seems that Estonia maybe will not change to
1080# summer time next spring."
1081
1082# From Peter Ilieve (1998-11-04), heavily edited:
1083# The 1998-09-22 Estonian time law
1084# http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390
1085# refers to the Eighth Directive and cites the association agreement between
1086# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22-27, 120).
1087#
1088# I also asked [my relative] whether they use any standard abbreviation
1089# for their standard and summer times. He says no, they use "suveaeg"
1090# (summer time) and "talveaeg" (winter time).

1092# From The Baltic Times <http://www.baltictimes.com/> (1999-09-09)
1093# via Steffen Thorsen:
1094# This year will mark the last time Estonia shifts to summer time,
1095# a council of the ruling coalition announced Sept. 6....
1096# But what this could mean for Estonia's chances of joining the European
1097# Union are still unclear.  In 1994, the EU declared summer time compulsory
1098# for all member states until 2001.  Brussels has yet to decide what to do
1099# after that.
1100
1101# From Mart Oruaas (2000-01-29):
1102# Regulation No. 301 (1999-10-12) obsoletes previous regulation

1418# Iceland
1419#
1420# From Adam David (1993-11-06):
1421# The name of the timezone in Iceland for system / mail / news purposes is GMT.
1422#
1423# (1993-12-05):
1424# This material is paraphrased from the 1988 edition of the University of
1425# Iceland Almanak.
1426#
1427# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1428# behind GMT. Previously, local mean solar time was used in different parts
1429# of Iceland, the almanak had been based on Reykjavik mean solar time which
1430# was 1 hour and 28 minutes behind GMT.
1431#
1432# "first day of winter" referred to [below] means the first day of the 26 weeks
1433# of winter, according to the old icelandic calendar that dates back to the
1434# time the norsemen first settled Iceland.  The first day of winter is always
1435# Saturday, but is not dependent on the Julian or Gregorian calendars.
1436#
1437# (1993-12-10):
1438# I have a reference from the Oxford Icelandic-English dictionary for the
1439# beginning of winter, which ties it to the ecclesiastical calendar (and thus
1440# to the julian/gregorian calendar) over the period in question.
1441#	the winter begins on the Saturday next before St. Luke's day
1442#	(old style), or on St. Luke's day, if a Saturday.
1443# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1444# might be a reference to the Julian calendar as opposed to Gregorian, or it
1445# might mean something else (???).

1585# transition to summer time is performed on the last Sunday of March at 02:00

1611# time in EU countries between 2002 and 2006. The Latvian government

1771# ... says that since 1990-05-06 on the territory of the Moldavian SSR
1772# time would be calculated as the standard time of the second time belt
1773# plus one hour of the "summer" time. To implement that clocks would be

1775# time would be cancelled last Sunday of September at 3:00 and
1776# reintroduced last Sunday of March at 2:00.
1777
1778# From Paul Eggert (2006-03-22):
1779# A previous version of this database followed Shanks & Pottenger, who write
1780# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1781# However, this is most likely an error, as Moldova declared independence
1782# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1783# In early 1992 there was large-scale interethnic violence in the area
1784# and it's possible that some Russophones continued to observe Moscow time.
1785# But [two people] separately reported via
1786# Jesper Nørgaard that as of 2001-01-24 Tiraspol was like Chisinau.
1787# The Tiraspol entry has therefore been removed for now.

1857# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
1858# but for other purposes the Netherlands used Amsterdam mean time.
1859
1860# However, Robert H. van Gent writes (2001-04-01):
1861# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
1862# Amsterdam mean time) onwards, the whole of the Netherlands (including
1863# the Dutch railways) was required by law to observe Amsterdam mean time
1864# (19 minutes 32.13 seconds ahead of GMT). This had already been the
1865# common practice (except for the railways) for many decades but it was
1866# not until 1909 when the Dutch government finally defined this by law.
1867# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
1868# was generally known as Dutch Time ("Nederlandse Tijd").
1869#
1870# (2001-04-08):
1871# 1892-05-01 was the date when the Dutch railways were by law required to
1872# observe GMT while the remainder of the Netherlands adhered to the common
1873# practice of following Amsterdam mean time.
1874#
1875# (2001-04-09):
1876# In 1835 the authorities of the province of North Holland requested the
1877# municipal authorities of the towns and cities in the province to observe
1878# Amsterdam mean time but I do not know in how many cases this request was
1879# actually followed.
1880#
1881# From 1852 onwards the Dutch telegraph offices were by law required to
1882# observe Amsterdam mean time. As the time signals from the observatory of
1883# Leiden were also distributed by the telegraph system, I assume that most
1884# places linked up with the telegraph (and railway) system automatically
1885# adopted Amsterdam mean time.
1886#
1887# Although the early Dutch railway companies initially observed a variety
1888# of times, most of them had adopted Amsterdam mean time by 1858 but it
1889# was not until 1866 when they were all required by law to observe
1890# Amsterdam mean time.

1947# Svalbard & Jan Mayen
1948
1949# From Steffen Thorsen (2001-05-01):
1950# Although I could not find it explicitly, it seems that Jan Mayen and
1951# Svalbard have been using the same time as Norway at least since the
1952# time they were declared as parts of Norway.  Svalbard was declared
1953# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
1954# Mayen by law of 1930-02-27 no 2, section 2. (From
1955# <http://www.lovdata.no/all/nl-19250717-011.html> and
1956# <http://www.lovdata.no/all/nl-19300227-002.html>).  The law/regulation
1957# for normal/standard time in Norway is from 1894-06-29 no 1 (came
1958# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
1959# part of this law since 1925/1930. (From
1960# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
1961# able to find if Jan Mayen used a different time zone (e.g. -0100)
1962# before 1930. Jan Mayen has only been "inhabited" since 1921 by
1963# Norwegian meteorologists and maybe used the same time as Norway ever
1964# since 1921.  Svalbard (Arctic/Longyearbyen) has been inhabited since
1965# before 1895, and therefore probably changed the local time somewhere
1966# between 1895 and 1925 (inclusive).
1967
1968# From Paul Eggert (2013-09-04):
1969#
1970# Actually, Jan Mayen was never occupied by Germany during World War II,
1971# so it must have diverged from Oslo time during the war, as Oslo was
1972# keeping Berlin time.
1973#
1974# <http://home.no.net/janmayen/history.htm> says that the meteorologists
1975# burned down their station in 1940 and left the island, but returned in
1976# 1941 with a small Norwegian garrison and continued operations despite
1977# frequent air attacks from Germans.  In 1943 the Americans established a
1978# radiolocating station on the island, called "Atlantic City".  Possibly
1979# the UT offset changed during the war, but I think it unlikely that
1980# Jan Mayen used German daylight-saving rules.
1981#
1982# Svalbard is more complicated, as it was raided in August 1941 by an
1983# Allied party that evacuated the civilian population to England (says
1984# <http://www.bartleby.com/65/sv/Svalbard.html>).  The Svalbard FAQ
1985# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
1986# expelled on 1942-05-14.  However, small parties of Germans did return,
1987# and according to Wilhelm Dege's book "War North of 80" (1954)
1988# http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html
1989# the German armed forces at the Svalbard weather station code-named
1990# Haudegen did not surrender to the Allies until September 1945.
1991#
1992# All these events predate our cutoff date of 1970, so use Europe/Oslo
1993# for these regions.

2042# Portugal
2043#
2044# From Paul Eggert (2014-08-11), after a heads-up from Stephen Colebourne:
2045# According to a Portuguese decree (1911-05-26)
2046# http://dre.pt/pdf1sdip/1911/05/12500/23132313.pdf
2047# Lisbon was at -0:36:44.68, but switched to GMT on 1912-01-01 at 00:00.
2048# Round the old offset to -0:36:45.  This agrees with Willett but disagrees
2049# with Shanks, who says the transition occurred on 1911-05-24 at 00:00 for
2050# Europe/Lisbon, Atlantic/Azores, and Atlantic/Madeira.
2051#
2052# From Rui Pedro Salgueiro (1992-11-12):
2053# Portugal has recently (September, 27) changed timezone
2054# (from WET to MET or CET) to harmonize with EEC.
2055#
2056# Martin Bruckmann (1996-02-29) reports via Peter Ilieve
2057# that Portugal is reverting to 0:00 by not moving its clocks this spring.
2058# The new Prime Minister was fed up with getting up in the dark in the winter.
2059#
2060# From Paul Eggert (1996-11-12):
2061# IATA SSIM (1991-09) reports several 1991-09 and 1992-09 transitions
2062# at 02:00u, not 01:00u.  Assume that these are typos.
2063# IATA SSIM (1991/1992) reports that the Azores were at -1:00.
2064# IATA SSIM (1993-02) says +0:00; later issues (through 1996-09) say -1:00.
2065# Guess that the Azores changed to EU rules in 1992 (since that's when Portugal
2066# harmonized with the EU), and that they stayed +0:00 that winter.

2281# For Grozny, Chechnya, we have the following story from
2282# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
2283# News - often false - is spread by word of mouth.  A rumor that it was
2284# time to move the clocks back put this whole city out of sync with
2285# the rest of Russia for two weeks - even soldiers stationed here began
2286# enforcing curfew at the wrong time.
2287#
2288# From Gwillim Law (2001-06-05):
2289# There's considerable evidence that Sakhalin Island used to be in
2290# UTC+11, and has changed to UTC+10, in this decade.  I start with the
2291# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
2292# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
2293# since September 1997....  Although the Kuril Islands are

2396# same Nauka i Zhizn articles converted to the text form (but misses
2397# time belt changes map).
2398#
2399# The second Nauka i Zhizn article says that in addition to
2400# introduction of summer time on 1981-04-01 there are some time belt
2401# border changes on 1981-10-01, mostly affecting Nenets Autonomous
2402# Okrug, Krasnoyarsk Krai, Yakutia, Magadan Oblast and Chukotka
2403# according to the provided map (colored one).  In addition to that
2404# "time violators" (regions which were not using rules of the time
2405# belts in which they were located) would not be moving off the DST on
2406# 1981-10-01 to restore the decree time usage.  (Komi ASSR was

2408# hour difference.)  Map depicting "time violators" before 1981-10-01
2409# is also provided.
2410#
2411# The article from Trud says that 1981-10-01 changes caused problems

3247# From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
3248#
3249# The law "Svensk författningssamling 1878, no 14" about standard time in 1879:
3250# From the beginning of 1879 (that is 01-01 00:00) the time for all
3251# places in the country is "the mean solar time for the meridian at
3252# three degrees, or twelve minutes of time, to the west of the
3253# meridian of the Observatory of Stockholm".  The law is dated 1878-05-31.
3254#
3255# The observatory at that time had the meridian 18 degrees 03' 30"
3256# eastern longitude = 01:12:14 in time.  Less 12 minutes gives the
3257# national standard time as 01:00:14 ahead of GMT....
3258#
3259# About the beginning of CET in Sweden. The lawtext ("Svensk
3260# författningssamling 1899, no 44") states, that "from the beginning
3261# of 1900... ... the same as the mean solar time for the meridian at
3262# the distance of one hour of time from the meridian of the English
3263# observatory at Greenwich, or at 12 minutes 14 seconds to the west
3264# from the meridian of the Observatory of Stockholm". The law is dated
3265# 1899-06-16.  In short: At 1900-01-01 00:00:00 the new standard time
3266# in Sweden is 01:00:00 ahead of GMT.
3267#
3268# 1916: The lawtext ("Svensk författningssamling 1916, no 124") states
3269# that "1916-05-15 is considered to begin one hour earlier". It is
3270# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
3271# Further the law says, that "1916-09-30 is considered to end one hour later".
3272#
3273# The laws regulating [DST] are available on the site of the Swedish
3274# Parliament beginning with 1985 - the laws regulating 1980/1984 are
3275# not available on the site (to my knowledge they are only available
3276# in Swedish): <http://www.riksdagen.se/english/work/sfst.asp> (type

3280# (2001-05-13):
3281#
3282# I have now found a newspaper stating that at 1916-10-01 01:00
3283# summertime the church-clocks etc were set back one hour to show
3284# 1916-10-01 00:00 standard time.  The article also reports that some
3285# people thought the switch to standard time would take place already
3286# at 1916-10-01 00:00 summer time, but they had to wait for another
3287# hour before the event took place.

3312# From Alois Treindl (2008-12-17):
3313# I have researched the DST usage in Switzerland during the 1940ies.
3314#
3315# As I wrote in an earlier message, I suspected the current tzdata values
3316# to be wrong. This is now verified.
3317#
3318# I have found copies of the original ruling by the Swiss Federal
3319# government, in 'Eidgenössische Gesetzessammlung 1941 and 1942' (Swiss
3320# federal law collection)...
3321#
3322# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
3323# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
3324#
3325# DST began on Monday, 4 May 1942 at 01:00 am
3326# DST ended on Monday, 5 Oct 1942 at 02:00 am
3327#
3328# There was no DST in 1940, I have checked the law collection carefully.
3329# It is also indicated by the fact that the 1942 entry in the law
3330# collection points back to 1941 as a reference, but no reference to any
3331# other years are made.
3332#
3333# Newspaper articles I have read in the archives on 6 May 1941 reported
3334# about the introduction of DST (Sommerzeit in German) during the previous
3335# night as an absolute novelty, because this was the first time that such
3336# a thing had happened in Switzerland.
3337#
3338# I have also checked 1916, because one book source (Gabriel, Traité de
3339# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
3340# false, no official document could be found. Probably Gabriel got misled
3341# by references to Germany, which introduced DST in 1916 for the first time.
3342#
3343# The tzdata rules for Switzerland must be changed to:
3344# Rule  Swiss   1941    1942    -       May     Mon>=1  1:00    1:00    S
3345# Rule  Swiss   1941    1942    -       Oct     Mon>=1  2:00    0       -
3346#
3347# The 1940 rules must be deleted.
3348#
3349# One further detail for Switzerland, which is probably out of scope for
3350# most users of tzdata: The [Europe/Zurich zone] ...
3351# describes all of Switzerland correctly, with the exception of
3352# the Canton de Genève (Geneva, Genf). Between 1848 and 1894 Geneva did not
3353# follow Bern Mean Time but kept its own local mean time.
3354# To represent this, an extra zone would be needed.
3355#
3356# From Alois Treindl (2013-09-11):
3357# The Federal regulations say
3358# http://www.admin.ch/opc/de/classified-compilation/20071096/index.html
3359# ... the meridian for Bern mean time ... is 7 degrees 26' 22.50".
3360# Expressed in time, it is 0h29m45.5s.
3361
3362# From Pierre-Yves Berger (2013-09-11):
3363# the "Circulaire du conseil fédéral" (December 11 1893)
3364# http://www.amtsdruckschriften.bar.admin.ch/viewOrigDoc.do?id=10071353
3365# clearly states that the [1894-06-01] change should be done at midnight
3366# but if no one is present after 11 at night, could be postponed until one
3367# hour before the beginning of service.
3368
3369# From Paul Eggert (2013-09-11):
3370# Round BMT to the nearest even second, 0:29:46.
3371#
3372# We can find no reliable source for Shanks's assertion that all of Switzerland
3373# except Geneva switched to Bern Mean Time at 00:00 on 1848-09-12.  This book:
3374#

3376#	Zeitgebrauch in der Schweiz im 19. Jahrhundert. Chronos, Zurich 1995,
3377#	ISBN 3-905311-68-2, OCLC 717570797.
3378#
3379# suggests that the transition was more gradual, and that the Swiss did not
3380# agree about civil time during the transition.  The timekeeping it gives the
3381# most detail for is postal and telegraph time: here, federal legislation (the
3382# "Bundesgesetz über die Erstellung von elektrischen Telegraphen") passed on
3383# 1851-11-23, and an official implementation notice was published 1853-07-16
3384# (Bundesblatt 1853, Bd. II, S. 859).  On p 72 Messerli writes that in
3385# practice since July 1853 Bernese time was used in "all postal and telegraph
3386# offices in Switzerland from Geneva to St. Gallen and Basel to Chiasso"
3387# (Google translation).  For now, model this transition as occurring on
3388# 1853-07-16, though it probably occurred at some other date in Zurich, and
3389# legal civil time probably changed at still some other transition date.

3542# BTW, I've found the official document on this matter. It's government
3543# regulations No. 509, May 13, 1996. In my poor translation it says:
3544# "Time in Ukraine is set to second timezone (Kiev time). Each last Sunday
3545# of March at 3am the time is changing to 4am and each last Sunday of
3546# October the time at 4am is changing to 3am"
3547
3548# From Alexander Krivenyshev (2011-09-20):

3653# One source shows that Bulgaria, Cyprus, Finland, and Greece observe DST from
3654# the last Sunday in March to the last Sunday in September in 1986.
3655# The source shows Romania changing a day later than everybody else.
3656#
3657# According to Bernard Sieloff's source, Poland is in the MET time zone but
3658# uses the WE DST rules.  The Western USSR uses EET+1 and ME DST rules.
3659# Bernard Sieloff's source claims Romania switches on the same day, but at

3668#
3669# ...the European time rules are...standardized since 1981, when
3670# most European countries started DST.  Before that year, only
3671# a few countries (UK, France, Italy) had DST, each according
3672# to own national rules.  In 1981, however, DST started on
3673# 'Apr firstSun', and not on 'Mar lastSun' as in the following
3674# years...
3675# But also since 1981 there are some more national exceptions
3676# than listed in 'europe': Switzerland, for example, joined DST
3677# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
3678# lastSun' in 1981 - I don't know how they handle now.
3679#
3680# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
3681# Soviet Union (as far as I know).

3691#
3692# The information from Tom Hofmann is (as far as I know) not entirely correct.
3693# After a request from chongo at amdahl I tried to retrieve all information
3694# about DST in Europe.  I was able to find all from about 1969.
3695#
3696# ...standardization on DST in Europe started in about 1977 with switches on
3697# first Sunday in April and last Sunday in September...
3698# In 1981 UK joined Europe insofar that
3699# the starting day for both shifted to last Sunday in March.  And from 1982
3700# the whole of Europe used DST, with switch dates April 1 and October 1 in
3701# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
3702# dates...
3703#
3704# It should also be remembered that time-zones are not constants; e.g.
3705# Portugal switched in 1976 from MET (or CET) to WET with DST...
3706# Note also that though there were rules for switch dates not
3707# all countries abided to these dates, and many individual deviations
3708# occurred, though not since 1982 I believe.  Another note: it is always
3709# assumed that DST is 1 hour ahead of normal time, this need not be the
3710# case; at least in the Netherlands there have been times when DST was 2 hours
3711# in advance of normal time.
