124# Britain (United Kingdom) and Ireland (Eire)
125
126# From Peter Ilieve (1994-07-06):
127#
128# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
129# historical vistas along the Thames in west London. There was a photo
130# and a sketch map showing some of the sightlines involved. One paragraph
131# of the text said:
132#
aefimov2aa78a52013-10-13 14:19:31 +0400133# 'An old stone obelisk marking a forgotten terrestrial meridian stands
duke6e45e102007-12-01 00:00:00 +0000134# beside the river at Kew. In the 18th century, before time and longitude
135# was standardised by the Royal Observatory in Greenwich, scholars observed
136# this stone and the movement of stars from Kew Observatory nearby. They
137# made their calculations and set the time for the Horse Guards and Parliament,
138# but now the stone is obscured by scrubwood and can only be seen by walking
139# along the towpath within a few yards of it.'
140#
141# I have a one inch to one mile map of London and my estimate of the stone's
aefimov3ffa7fa2014-09-07 23:04:09 +0400142# position is 51 degrees 28' 30" N, 0 degrees 18' 45" W. The longitude should
duke6e45e102007-12-01 00:00:00 +0000143# be within about +-2". The Ordnance Survey grid reference is TQ172761.
144#
145# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
146
147# From Paul Eggert (1993-11-18):
148#
149# Howse writes that Britain was the first country to use standard time.
150# The railways cared most about the inconsistencies of local mean time,
151# and it was they who forced a uniform time on the country.
152# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
153# and was popularized by Abraham Follett Osler (1808-1903).
154# The first railway to adopt London time was the Great Western Railway
155# in November 1840; other railways followed suit, and by 1847 most
156# (though not all) railways used London time. On 1847-09-22 the
157# Railway Clearing House, an industry standards body, recommended that GMT be
158# adopted at all stations as soon as the General Post Office permitted it.
159# The transition occurred on 12-01 for the L&NW, the Caledonian,
160# and presumably other railways; the January 1848 Bradshaw's lists many
161# railways as using GMT. By 1855 the vast majority of public
162# clocks in Britain were set to GMT (though some, like the great clock
163# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
164# one for local time and one for GMT). The last major holdout was the legal
165# system, which stubbornly stuck to local time for many years, leading
166# to oddities like polls opening at 08:13 and closing at 16:13.
167# The legal system finally switched to GMT when the Statutes (Definition
168# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
169#
170# In the tables below, we condense this complicated story into a single
171# transition date for London, namely 1847-12-01. We don't know as much
172# about Dublin, so we use 1880-08-02, the legal transition time.
173
aefimov3ffa7fa2014-09-07 23:04:09 +0400174# From Paul Eggert (2014-07-19):
175# The ancients had no need for daylight saving, as they kept time
176# informally or via hours whose length depended on the time of year.
177# Daylight saving time in its modern sense was invented by the
178# New Zealand entomologist George Vernon Hudson (1867-1946),
179# whose day job as a postal clerk led him to value
180# after-hours daylight in which to pursue his research.
181# In 1895 he presented a paper to the Wellington Philosophical Society
182# that proposed a two-hour daylight-saving shift. See:
183# Hudson GV. On seasonal time-adjustment in countries south of lat. 30 deg.
184# Transactions and Proceedings of the New Zealand Institute. 1895;28:734
185# http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
186# Although some interest was expressed in New Zealand, his proposal
187# did not find its way into law and eventually it was almost forgotten.
188#
189# In England, DST was independently reinvented by William Willett (1857-1915),
duke6e45e102007-12-01 00:00:00 +0000190# a London builder and member of the Royal Astronomical Society
aefimov2aa78a52013-10-13 14:19:31 +0400191# who circulated a pamphlet "The Waste of Daylight" (1907)
duke6e45e102007-12-01 00:00:00 +0000192# that proposed advancing clocks 20 minutes on each of four Sundays in April,
193# and retarding them by the same amount on four Sundays in September.
194# A bill was drafted in 1909 and introduced in Parliament several times,
195# but it met with ridicule and opposition, especially from farming interests.
196# Later editions of the pamphlet proposed one-hour summer time, and
197# it was eventually adopted as a wartime measure in 1916.
198# See: Summer Time Arrives Early, The Times (2000-05-18).
199# A monument to Willett was unveiled on 1927-05-21, in an open space in
200# a 45-acre wood near Chislehurst, Kent that was purchased by popular
201# subscription and open to the public. On the south face of the monolith,
aefimov3ffa7fa2014-09-07 23:04:09 +0400202# designed by G. W. Miller, is the William Willett Memorial Sundial,
duke6e45e102007-12-01 00:00:00 +0000203# which is permanently set to Summer Time.
204
205# From Winston Churchill (1934-04-28):
206# It is one of the paradoxes of history that we should owe the boon of
207# summer time, which gives every year to the people of this country
208# between 160 and 170 hours more daylight leisure, to a war which
209# plunged Europe into darkness for four years, and shook the
210# foundations of civilization throughout the world.

aefimov2aa78a52013-10-13 14:19:31 +0400216# The OED Supplement says that the English originally said "Daylight Saving"
duke6e45e102007-12-01 00:00:00 +0000217# when they were debating the adoption of DST in 1908; but by 1916 this
218# term appears only in quotes taken from DST's opponents, whereas the
aefimov2aa78a52013-10-13 14:19:31 +0400219# proponents (who eventually won the argument) are quoted as using "Summer".
duke6e45e102007-12-01 00:00:00 +0000220
221# From Arthur David Olson (1989-01-19):
duke6e45e102007-12-01 00:00:00 +0000222# A source at the British Information Office in New York avers that it's
223# known as "British" Summer Time in all parts of the United Kingdom.

230
231# From Chris Carrier (1996-06-14):
232# I remember reading in various wartime issues of the London Times the
233# acronym BDST for British Double Summer Time. Look for the published
234# time of sunrise and sunset in The Times, when BDST was in effect, and
235# if you find a zone reference it will say, "All times B.D.S.T."
236
237# From Joseph S. Myers (1999-09-02):
238# ... some military cables (WO 219/4100 - this is a copy from the
239# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
240# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
241
242# From Joseph S. Myers (2000-10-03):
243# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
244# Alexander Maxwell of the Home Office asking whether there was any
245# official designation; the reply of the 21st was that there wasn't
246# but he couldn't think of anything better than the "Double British
247# Summer Time" that the BBC had been using informally.

aefimov2aa78a52013-10-13 14:19:31 +0400258# Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common

268# From Joseph S. Myers (1998-01-06):
269#
270# The legal time in the UK outside of summer time is definitely GMT, not UTC;

duke6e45e102007-12-01 00:00:00 +0000274
275# From Paul Eggert (2006-03-22):
276#
277# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
278#
279# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
280# are incorrect:
281# * Wales did not switch from GMT to daylight saving time until
282# 1921 Apr 3, when they began to conform with the rest of Great Britain.
283# Actually, Wales was identical after 1880.
284# * Eire had two transitions on 1916 Oct 1.
285# It actually just had one transition.
286# * Northern Ireland used single daylight saving time throughout WW II.
287# Actually, it conformed to Britain.
288# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
289# Actually, that date saw the usual switch to summer time.
290# Standard time was not changed until 1968-10-27 (the clocks didn't change).
291#
292# Here is another incorrect claim by Shanks & Pottenger:
293# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
294# to daylight saving time until 1921 Apr 3, when they began to
295# conform with Great Britain.
296# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
297#
298# The following claim by Shanks & Pottenger is possible though doubtful;
299# we'll ignore it for now.
300# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
301#
302#
303# Whitman says Dublin Mean Time was -0:25:21, which is more precise than
304# Shanks & Pottenger.
305# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
306# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
307# to London. For example:
308#
309# "Timeball on the ballast office is down. Dunsink time."

341# From Paul Eggert (1999-03-28):
342# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
343# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
344# (CT), equivalent to French civil time.
345# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
346# trains between Dollands Moor (the freight facility next door)
347# and Frethun run in CT.
348# My admittedly uninformed guess is that the terminal has two authorities,
349# the French concession operators and the British civil authorities,
350# and that the time depends on who you're talking to.
351# If, say, the British police were called to the station for some reason,
352# I would expect the official police report to use GMT/BST and not CET/CEST.
353# This is a borderline case, but for now let's stick to GMT/BST.
354
355# From an anonymous contributor (1996-06-02):
356# The law governing time in Ireland is under Statutory Instrument SI 395/94,
357# which gives force to European Union 7th Council Directive # 94/21/EC.
358# Under this directive, the Minister for Justice in Ireland makes appropriate
359# regulations. I spoke this morning with the Secretary of the Department of
360# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
361# "Irish Summer Time", abbreviated to "IST".

duke6e45e102007-12-01 00:00:00 +0000881# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
882# [introducing standard time] was in effect from 1894-01-01....
883# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
884# confirms this, and states that the law was put forth 1893-03-29.
885#
886# The EU treaty with effect from 1973:
887# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
888#
889# This provoked a new law from 1974 to make possible summer time changes
aefimov3ffa7fa2014-09-07 23:04:09 +0400890# in subsequent decrees with the law
duke6e45e102007-12-01 00:00:00 +0000891# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
892#
893# It seems however that no decree was set forward until 1980. I have
894# not found any decree, but in another related law, the effecting DST
895# changes are stated explicitly to be from 1980-04-06 at 02:00 to
896# 1980-09-28 at 02:00. If this is true, this differs slightly from
897# the EU rule in that DST runs to 02:00, not 03:00. We don't know
898# when Denmark began using the EU rule correctly, but we have only
899# confirmation of the 1980-time, so I presume it was correct in 1981:
900# The law is about the management of the extra hour, concerning
901# working hours reported and effect on obligatory-rest rules (which
902# was suspended on that night):

908
909# From Paul Eggert (2005-06-11):

952#
953# Greenland has four local times, and the relation to UTC
954# is according to the following time line:
955#
956# The military zone near Thule UTC-4
957# Standard Greenland time UTC-3
958# Scoresbysund UTC-1
959# Danmarkshavn UTC
960#
961# In the military area near Thule and in Danmarkshavn DST will not be

964# From Rives McDow (2001-11-01):
965#
966# I correspond regularly with the Dansk Polarcenter, and wrote them at
967# the time to clarify the situation in Thule. Unfortunately, I have
968# not heard back from them regarding my recent letter. [But I have
969# info from earlier correspondence.]
970#
971# According to the center, a very small local time zone around Thule
972# Air Base keeps the time according to UTC-4, implementing daylight
973# savings using North America rules, changing the time at 02:00 local time....
974#
975# The east coast of Greenland north of the community of Scoresbysund
976# uses UTC in the same way as in Iceland, year round, with no dst.
977# There are just a few stations on this coast, including the
978# Danmarkshavn ICAO weather station mentioned in your September 29th
979# email. The other stations are two sledge patrol stations in
980# Mestersvig and Daneborg, the air force base at Station Nord, and the
981# DPC research station at Zackenberg.
982#
983# Scoresbysund and two small villages nearby keep time UTC-1 and use
aefimov3ffa7fa2014-09-07 23:04:09 +0400984# the same daylight savings time period as in West Greenland (Godthåb).
duke6e45e102007-12-01 00:00:00 +0000985#

duke6e45e102007-12-01 00:00:00 +0000987# includes central Greenland, is known as west Greenland), keeps time
988# UTC-3, with daylight savings methods according to European rules.
989#
990# It is common procedure to use UTC 0 in the wilderness of East and
991# North Greenland, because it is mainly Icelandic aircraft operators
992# maintaining traffic in these areas. However, the official status of
aefimov3ffa7fa2014-09-07 23:04:09 +0400993# this area is that it sticks with Godthåb time. This area might be
duke6e45e102007-12-01 00:00:00 +0000994# considered a dual time zone in some respects because of this.
995
996# From Rives McDow (2001-11-19):
997# I heard back from someone stationed at Thule; the time change took place
998# there at 2:00 AM.

1392# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1393# behind GMT. Previously, local mean solar time was used in different parts
1394# of Iceland, the almanak had been based on Reykjavik mean solar time which
1395# was 1 hour and 28 minutes behind GMT.
1396#
1397# "first day of winter" referred to [below] means the first day of the 26 weeks
1398# of winter, according to the old icelandic calendar that dates back to the
1399# time the norsemen first settled Iceland. The first day of winter is always
1400# Saturday, but is not dependent on the Julian or Gregorian calendars.
1401#
1402# (1993-12-10):
1403# I have a reference from the Oxford Icelandic-English dictionary for the
1404# beginning of winter, which ties it to the ecclesiastical calendar (and thus
1405# to the julian/gregorian calendar) over the period in question.
1406# the winter begins on the Saturday next before St. Luke's day
1407# (old style), or on St. Luke's day, if a Saturday.
1408# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1409# might be a reference to the Julian calendar as opposed to Gregorian, or it
1410# might mean something else (???).
1411#
1412# From Paul Eggert (2006-03-22):
1413# The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points.
1414# We go with the Almanak, except for one claim from Shanks & Pottenger, namely
1415# that Reykavik was 21W57 from 1837 to 1908, local mean time before that.

1734# A previous version of this database followed Shanks & Pottenger, who write
1735# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1736# However, this is most likely an error, as Moldova declared independence
1737# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1738# In early 1992 there was large-scale interethnic violence in the area
1739# and it's possible that some Russophones continued to observe Moscow time.
1740# But [two people] separately reported via

1800# Netherlands
1801
1802# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
1803# but for other purposes the Netherlands used Amsterdam mean time.
1804
1805# However, Robert H. van Gent writes (2001-04-01):
1806# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
1807# Amsterdam mean time) onwards, the whole of the Netherlands (including
1808# the Dutch railways) was required by law to observe Amsterdam mean time
1809# (19 minutes 32.13 seconds ahead of GMT). This had already been the
1810# common practice (except for the railways) for many decades but it was
1811# not until 1909 when the Dutch government finally defined this by law.
1812# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
1813# was generally known as Dutch Time ("Nederlandse Tijd").
1814#
1815# (2001-04-08):
1816# 1892-05-01 was the date when the Dutch railways were by law required to
1817# observe GMT while the remainder of the Netherlands adhered to the common
1818# practice of following Amsterdam mean time.
1819#
1820# (2001-04-09):
1821# In 1835 the authorities of the province of North Holland requested the
1822# municipal authorities of the towns and cities in the province to observe
1823# Amsterdam mean time but I do not know in how many cases this request was
1824# actually followed.
1825#
1826# From 1852 onwards the Dutch telegraph offices were by law required to
1827# observe Amsterdam mean time. As the time signals from the observatory of
1828# Leiden were also distributed by the telegraph system, I assume that most
1829# places linked up with the telegraph (and railway) system automatically
1830# adopted Amsterdam mean time.
1831#
1832# Although the early Dutch railway companies initially observed a variety
1833# of times, most of them had adopted Amsterdam mean time by 1858 but it
1834# was not until 1866 when they were all required by law to observe
1835# Amsterdam mean time.

1892# Svalbard & Jan Mayen
1893
1894# From Steffen Thorsen (2001-05-01):
1895# Although I could not find it explicitly, it seems that Jan Mayen and
1896# Svalbard have been using the same time as Norway at least since the
1897# time they were declared as parts of Norway. Svalbard was declared
1898# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
1899# Mayen by law of 1930-02-27 no 2, section 2. (From
aefimov3ffa7fa2014-09-07 23:04:09 +04001900# <http://www.lovdata.no/all/nl-19250717-011.html> and
1901# <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
duke6e45e102007-12-01 00:00:00 +00001902# for normal/standard time in Norway is from 1894-06-29 no 1 (came
1903# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a

duke6e45e102007-12-01 00:00:00 +00001906# able to find if Jan Mayen used a different time zone (e.g. -0100)
aefimov3ffa7fa2014-09-07 23:04:09 +04001907# before 1930. Jan Mayen has only been "inhabited" since 1921 by
duke6e45e102007-12-01 00:00:00 +00001908# Norwegian meteorologists and maybe used the same time as Norway ever
1909# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
1910# before 1895, and therefore probably changed the local time somewhere
1911# between 1895 and 1925 (inclusive).
1912
aefimov2aa78a52013-10-13 14:19:31 +04001913# From Paul Eggert (2013-09-04):

1915# Actually, Jan Mayen was never occupied by Germany during World War II,
1916# so it must have diverged from Oslo time during the war, as Oslo was
1917# keeping Berlin time.
1918#
1919# <http://home.no.net/janmayen/history.htm> says that the meteorologists
1920# burned down their station in 1940 and left the island, but returned in
1921# 1941 with a small Norwegian garrison and continued operations despite
aefimov3ffa7fa2014-09-07 23:04:09 +04001922# frequent air attacks from Germans. In 1943 the Americans established a
duke6e45e102007-12-01 00:00:00 +00001923# radiolocating station on the island, called "Atlantic City". Possibly
aefimov2aa78a52013-10-13 14:19:31 +04001924# the UT offset changed during the war, but I think it unlikely that
duke6e45e102007-12-01 00:00:00 +00001925# Jan Mayen used German daylight-saving rules.
1926#
1927# Svalbard is more complicated, as it was raided in August 1941 by an
1928# Allied party that evacuated the civilian population to England (says
1929# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ
1930# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
1931# expelled on 1942-05-14. However, small parties of Germans did return,
1932# and according to Wilhelm Dege's book "War North of 80" (1954)

1993# Round the old offset to -0:36:45. This agrees with Willett but disagrees
1994# with Shanks, who says the transition occurred on 1911-05-24 at 00:00 for
1995# Europe/Lisbon, Atlantic/Azores, and Atlantic/Madeira.

duke6e45e102007-12-01 00:00:00 +00002229# time to move the clocks back put this whole city out of sync with

duke6e45e102007-12-01 00:00:00 +00002231# enforcing curfew at the wrong time.
2232#
2233# From Gwillim Law (2001-06-05):
2234# There's considerable evidence that Sakhalin Island used to be in
2235# UTC+11, and has changed to UTC+10, in this decade. I start with the
2236# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
2237# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
2238# since September 1997.... Although the Kuril Islands are
2239# administratively part of Sakhalin oblast', they appear to have
2240# remained on UTC+11 along with Magadan.

2937# From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
2938#
aefimov3ffa7fa2014-09-07 23:04:09 +04002939# The law "Svensk författningssamling 1878, no 14" about standard time in 1879:
duke6e45e102007-12-01 00:00:00 +00002940# From the beginning of 1879 (that is 01-01 00:00) the time for all
2941# places in the country is "the mean solar time for the meridian at
2942# three degrees, or twelve minutes of time, to the west of the
2943# meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
2944#
2945# The observatory at that time had the meridian 18 degrees 03' 30"
2946# eastern longitude = 01:12:14 in time. Less 12 minutes gives the
2947# national standard time as 01:00:14 ahead of GMT....
2948#
2949# About the beginning of CET in Sweden. The lawtext ("Svensk
aefimov3ffa7fa2014-09-07 23:04:09 +04002950# författningssamling 1899, no 44") states, that "from the beginning
duke6e45e102007-12-01 00:00:00 +00002951# of 1900... ... the same as the mean solar time for the meridian at
2952# the distance of one hour of time from the meridian of the English
2953# observatory at Greenwich, or at 12 minutes 14 seconds to the west
2954# from the meridian of the Observatory of Stockholm". The law is dated
2955# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
2956# in Sweden is 01:00:00 ahead of GMT.
2957#
aefimov3ffa7fa2014-09-07 23:04:09 +04002958# 1916: The lawtext ("Svensk författningssamling 1916, no 124") states
duke6e45e102007-12-01 00:00:00 +00002959# that "1916-05-15 is considered to begin one hour earlier". It is
2960# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
2961# Further the law says, that "1916-09-30 is considered to end one hour later".

3002# From Alois Treindl (2008-12-17):
3003# I have researched the DST usage in Switzerland during the 1940ies.
3004#
3005# As I wrote in an earlier message, I suspected the current tzdata values
3006# to be wrong. This is now verified.
3007#
3008# I have found copies of the original ruling by the Swiss Federal
aefimov3ffa7fa2014-09-07 23:04:09 +04003009# government, in 'Eidgenössische Gesetzessammlung 1941 and 1942' (Swiss
peytoiac767ad52009-01-26 09:19:59 +09003010# federal law collection)...
3011#
3012# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
3013# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
3014#
3015# DST began on Monday, 4 May 1942 at 01:00 am
3016# DST ended on Monday, 5 Oct 1942 at 02:00 am
3017#
3018# There was no DST in 1940, I have checked the law collection carefully.
3019# It is also indicated by the fact that the 1942 entry in the law
3020# collection points back to 1941 as a reference, but no reference to any
3021# other years are made.
3022#
3023# Newspaper articles I have read in the archives on 6 May 1941 reported
3024# about the introduction of DST (Sommerzeit in German) during the previous
3025# night as an absolute novelty, because this was the first time that such
3026# a thing had happened in Switzerland.
3027#
aefimov3ffa7fa2014-09-07 23:04:09 +04003028# I have also checked 1916, because one book source (Gabriel, Traité de
peytoiac767ad52009-01-26 09:19:59 +09003029# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
3030# false, no official document could be found. Probably Gabriel got misled
3031# by references to Germany, which introduced DST in 1916 for the first time.
3032#
3033# The tzdata rules for Switzerland must be changed to:
3034# Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S
3035# Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 -

3068#
3069# suggests that the transition was more gradual, and that the Swiss did not
3070# agree about civil time during the transition. The timekeeping it gives the
3071# most detail for is postal and telegraph time: here, federal legislation (the
aefimov3ffa7fa2014-09-07 23:04:09 +04003072# "Bundesgesetz über die Erstellung von elektrischen Telegraphen") passed on
aefimov2aa78a52013-10-13 14:19:31 +04003073# 1851-11-23, and an official implementation notice was published 1853-07-16
3074# (Bundesblatt 1853, Bd. II, S. 859). On p 72 Messerli writes that in
3075# practice since July 1853 Bernese time was used in "all postal and telegraph
3076# offices in Switzerland from Geneva to St. Gallen and Basel to Chiasso"
3077# (Google translation). For now, model this transition as occurring on
3078# 1853-07-16, though it probably occurred at some other date in Zurich, and
3079# legal civil time probably changed at still some other transition date.

3338# switches on the same day, but switches on at 01:00 standard time
3339# and off at 00:00 standard time (i.e., 01:00 DST)

3346# ...the European time rules are...standardized since 1981, when
aefimov3ffa7fa2014-09-07 23:04:09 +04003347# most European countries started DST. Before that year, only
duke6e45e102007-12-01 00:00:00 +00003348# a few countries (UK, France, Italy) had DST, each according
3349# to own national rules. In 1981, however, DST started on
3350# 'Apr firstSun', and not on 'Mar lastSun' as in the following
3351# years...
3352# But also since 1981 there are some more national exceptions
3353# than listed in 'europe': Switzerland, for example, joined DST
3354# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
aefimov3ffa7fa2014-09-07 23:04:09 +04003355# lastSun' in 1981 - I don't know how they handle now.

3357# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
3358# Soviet Union (as far as I know).

3368#
3369# The information from Tom Hofmann is (as far as I know) not entirely correct.
3370# After a request from chongo at amdahl I tried to retrieve all information
3371# about DST in Europe. I was able to find all from about 1969.
3372#
3373# ...standardization on DST in Europe started in about 1977 with switches on
3374# first Sunday in April and last Sunday in September...
3375# In 1981 UK joined Europe insofar that
3376# the starting day for both shifted to last Sunday in March. And from 1982
3377# the whole of Europe used DST, with switch dates April 1 and October 1 in
3378# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
3379# dates...
3380#
3381# It should also be remembered that time-zones are not constants; e.g.
3382# Portugal switched in 1976 from MET (or CET) to WET with DST...
3383# Note also that though there were rules for switch dates not
3384# all countries abided to these dates, and many individual deviations
3385# occurred, though not since 1982 I believe. Another note: it is always
3386# assumed that DST is 1 hour ahead of normal time, this need not be the
3387# case; at least in the Netherlands there have been times when DST was 2 hours
3388# in advance of normal time.
