+# Britain (United Kingdom) and Ireland (Eire)
+# From Peter Ilieve (1994-07-06):
+#
+# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
+# historical vistas along the Thames in west London. There was a photo
+# and a sketch map showing some of the sightlines involved. One paragraph
+# of the text said:
+#
+# `An old stone obelisk marking a forgotten terrestrial meridian stands
+# beside the river at Kew. In the 18th century, before time and longitude
+# was standardised by the Royal Observatory in Greenwich, scholars observed
+# this stone and the movement of stars from Kew Observatory nearby. They
+# made their calculations and set the time for the Horse Guards and Parliament,
+# but now the stone is obscured by scrubwood and can only be seen by walking
+# along the towpath within a few yards of it.'
+#
+# I have a one inch to one mile map of London and my estimate of the stone's
+# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
+# be within about +-2". The Ordnance Survey grid reference is TQ172761.
+#
+# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
+# From Paul Eggert (1993-11-18):
+#
+# Howse writes that Britain was the first country to use standard time.
+# The railways cared most about the inconsistencies of local mean time,
+# and it was they who forced a uniform time on the country.
+# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
+# and was popularized by Abraham Follett Osler (1808-1903).
+# The first railway to adopt London time was the Great Western Railway
+# in November 1840; other railways followed suit, and by 1847 most
+# (though not all) railways used London time.  On 1847-09-22 the
+# Railway Clearing House, an industry standards body, recommended that GMT be
+# adopted at all stations as soon as the General Post Office permitted it.
+# The transition occurred on 12-01 for the L&NW, the Caledonian,
+# and presumably other railways; the January 1848 Bradshaw's lists many
+# railways as using GMT.  By 1855 the vast majority of public
+# clocks in Britain were set to GMT (though some, like the great clock
+# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
+# one for local time and one for GMT).  The last major holdout was the legal
+# system, which stubbornly stuck to local time for many years, leading
+# to oddities like polls opening at 08:13 and closing at 16:13.
+# The legal system finally switched to GMT when the Statutes (Definition
+# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
+#
+# In the tables below, we condense this complicated story into a single
+# transition date for London, namely 1847-12-01.  We don't know as much
+# about Dublin, so we use 1880-08-02, the legal transition time.
+# From Paul Eggert (2003-09-27):
+# Summer Time was first seriously proposed by William Willett (1857-1915),
+# a London builder and member of the Royal Astronomical Society
+# who circulated a pamphlet ``The Waste of Daylight'' (1907)
+# that proposed advancing clocks 20 minutes on each of four Sundays in April,
+# and retarding them by the same amount on four Sundays in September.
+# A bill was drafted in 1909 and introduced in Parliament several times,
+# but it met with ridicule and opposition, especially from farming interests.
+# Later editions of the pamphlet proposed one-hour summer time, and
+# it was eventually adopted as a wartime measure in 1916.
+# See: Summer Time Arrives Early, The Times (2000-05-18).
+# A monument to Willett was unveiled on 1927-05-21, in an open space in
+# a 45-acre wood near Chislehurst, Kent that was purchased by popular
+# subscription and open to the public.  On the south face of the monolith,
+# designed by G. W. Miller, is the the William Willett Memorial Sundial,
+# which is permanently set to Summer Time.
+# From Winston Churchill (1934-04-28):
+# It is one of the paradoxes of history that we should owe the boon of
+# summer time, which gives every year to the people of this country
+# between 160 and 170 hours more daylight leisure, to a war which
+# plunged Europe into darkness for four years, and shook the
+# foundations of civilization throughout the world.
+#	-- <a href="http://www.winstonchurchill.org/fh114willett.htm">
+#	"A Silent Toast to William Willett", Pictorial Weekly
+#	</a>
+# From Paul Eggert (1996-09-03):
+# The OED Supplement says that the English originally said ``Daylight Saving''
+# when they were debating the adoption of DST in 1908; but by 1916 this
+# term appears only in quotes taken from DST's opponents, whereas the
+# proponents (who eventually won the argument) are quoted as using ``Summer''.
+# From Arthur David Olson (1989-01-19):
+#
+# A source at the British Information Office in New York avers that it's
+# known as "British" Summer Time in all parts of the United Kingdom.
+# Date: 4 Jan 89 08:57:25 GMT (Wed)
+# From: Jonathan Leffler
+# [British Summer Time] is fixed annually by Act of Parliament.
+# If you can predict what Parliament will do, you should be in
+# politics making a fortune, not computing.
+# From Chris Carrier (1996-06-14):
+# I remember reading in various wartime issues of the London Times the
+# acronym BDST for British Double Summer Time.  Look for the published
+# time of sunrise and sunset in The Times, when BDST was in effect, and
+# if you find a zone reference it will say, "All times B.D.S.T."
+# From Joseph S. Myers (1999-09-02):
+# ... some military cables (WO 219/4100 - this is a copy from the
+# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
+# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
+# From Joseph S. Myers (2000-10-03):
+# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
+# Alexander Maxwell of the Home Office asking whether there was any
+# official designation; the reply of the 21st was that there wasn't
+# but he couldn't think of anything better than the "Double British
+# Summer Time" that the BBC had been using informally.

+# http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png
+# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
+# [N]o official designation has as far as I know been adopted for the time
+# which is to be introduced in May....
+# I cannot think of anything better than "Double British Summer Time"
+# which could not be said to run counter to any official description.
+# From Paul Eggert (2000-10-02):
+# Howse writes (p 157) `DBST' too, but `BDST' seems to have been common
+# and follows the more usual convention of putting the location name first,
+# so we use `BDST'.
+# Peter Ilieve (1998-04-19) described at length
+# the history of summer time legislation in the United Kingdom.
+# Since 1998 Joseph S. Myers has been updating
+# and extending this list, which can be found in

+# History of legal time in Britain
+# </a>
+# From Joseph S. Myers (1998-01-06):
+#
+# The legal time in the UK outside of summer time is definitely GMT, not UTC;
+# see Lord Tanlaw's speech
+# <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn/lds97/text/70611-20.htm#70611-20_head0">
+# (Lords Hansard 11 June 1997 columns 964 to 976)
+# </a>.
+# From Paul Eggert (2006-03-22):
+#
+# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
+#
+# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
+# are incorrect:
+#     * Wales did not switch from GMT to daylight saving time until
+#	1921 Apr 3, when they began to conform with the rest of Great Britain.
+# Actually, Wales was identical after 1880.
+#     * Eire had two transitions on 1916 Oct 1.
+# It actually just had one transition.
+#     * Northern Ireland used single daylight saving time throughout WW II.
+# Actually, it conformed to Britain.
+#     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
+# Actually, that date saw the usual switch to summer time.
+# Standard time was not changed until 1968-10-27 (the clocks didn't change).
+#
+# Here is another incorrect claim by Shanks & Pottenger:
+#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
+#	to daylight saving time until 1921 Apr 3, when they began to
+#	conform with Great Britain.
+# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
+#
+# The following claim by Shanks & Pottenger is possible though doubtful;
+# we'll ignore it for now.
+#     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
+#
+#
+# Whitman says Dublin Mean Time was -0:25:21, which is more precise than
+# Shanks & Pottenger.
+# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
+# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
+# to London.  For example:
+#
+#   "Timeball on the ballast office is down.  Dunsink time."
+#   -- James Joyce, Ulysses
+# From Joseph S. Myers (2005-01-26):
+# Irish laws are available online at www.irishstatutebook.ie.  These include
+# various relating to legal time, for example:

+#
+# (These are those I found, but there could be more.  In any case these
+# should allow various updates to the comments in the europe file to cover
+# the laws applicable in Ireland.)
+#
+# (Note that the time in the Republic of Ireland since 1968 has been defined
+# in terms of standard time being GMT+1 with a period of winter time when it
+# is GMT, rather than standard time being GMT with a period of summer time
+# being GMT+1.)
+# From Paul Eggert (1999-03-28):
+# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
+# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
+# (CT), equivalent to French civil time.
+# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
+# trains between Dollands Moor (the freight facility next door)
+# and Frethun run in CT.
+# My admittedly uninformed guess is that the terminal has two authorities,
+# the French concession operators and the British civil authorities,
+# and that the time depends on who you're talking to.
+# If, say, the British police were called to the station for some reason,
+# I would expect the official police report to use GMT/BST and not CET/CEST.
+# This is a borderline case, but for now let's stick to GMT/BST.
+# From an anonymous contributor (1996-06-02):
+# The law governing time in Ireland is under Statutory Instrument SI 395/94,
+# which gives force to European Union 7th Council Directive # 94/21/EC.
+# Under this directive, the Minister for Justice in Ireland makes appropriate
+# regulations. I spoke this morning with the Secretary of the Department of
+# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
+# "Irish Summer Time", abbreviated to "IST".

+# Denmark, Faeroe Islands, and Greenland
+# From Jesper Norgaard Welen (2005-04-26):
+# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
+# [introducing standard time] was in effect from 1894-01-01....
+# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
+# confirms this, and states that the law was put forth 1893-03-29.
+#
+# The EU treaty with effect from 1973:
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
+#
+# This provoked a new law from 1974 to make possible summer time changes
+# in subsequenet decrees with the law
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
+#
+# It seems however that no decree was set forward until 1980.  I have
+# not found any decree, but in another related law, the effecting DST
+# changes are stated explicitly to be from 1980-04-06 at 02:00 to
+# 1980-09-28 at 02:00.  If this is true, this differs slightly from
+# the EU rule in that DST runs to 02:00, not 03:00.  We don't know
+# when Denmark began using the EU rule correctly, but we have only
+# confirmation of the 1980-time, so I presume it was correct in 1981:
+# The law is about the management of the extra hour, concerning
+# working hours reported and effect on obligatory-rest rules (which
+# was suspended on that night):
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL
+# From Jesper Norgaard Welen (2005-06-11):
+# The Herning Folkeblad (1980-09-26) reported that the night between
+# Saturday and Sunday the clock is set back from three to two.
+# From Paul Eggert (2005-06-11):
+# Hence the "02:00" of the 1980 law refers to standard time, not
+# wall-clock time, and so the EU rules were in effect in 1980.

+# From Paul Eggert (2004-10-31):
+# During World War II, Germany maintained secret manned weather stations in

+# My source for this is Wilhelm Dege's book mentioned under Svalbard.
+#
+# From Paul Eggert (2006-03-22):
+# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
+# and left the EU on 1985-02-01.  It therefore should have been using EU
+# rules at least through 1984.  Shanks & Pottenger say Scoresbysund and Godthab
+# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
+# rules since at least 1991.  Assume EU rules since 1980.
+# From Gwillin Law (2001-06-06), citing
+# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
+# and with translations corrected by Steffen Thorsen:
+#
+# Greenland has four local times, and the relation to UTC
+# is according to the following time line:
+#
+# The military zone near Thule	UTC-4
+# Standard Greenland time	UTC-3
+# Scoresbysund			UTC-1
+# Danmarkshavn			UTC
+#
+# In the military area near Thule and in Danmarkshavn DST will not be
+# introduced.
+# From Rives McDow (2001-11-01):
+#
+# I correspond regularly with the Dansk Polarcenter, and wrote them at
+# the time to clarify the situation in Thule.  Unfortunately, I have
+# not heard back from them regarding my recent letter.  [But I have
+# info from earlier correspondence.]
+#
+# According to the center, a very small local time zone around Thule
+# Air Base keeps the time according to UTC-4, implementing daylight
+# savings using North America rules, changing the time at 02:00 local time....
+#
+# The east coast of Greenland north of the community of Scoresbysund
+# uses UTC in the same way as in Iceland, year round, with no dst.
+# There are just a few stations on this coast, including the
+# Danmarkshavn ICAO weather station mentioned in your September 29th
+# email.  The other stations are two sledge patrol stations in
+# Mestersvig and Daneborg, the air force base at Station Nord, and the
+# DPC research station at Zackenberg.
+#
+# Scoresbysund and two small villages nearby keep time UTC-1 and use
+# the same daylight savings time period as in West Greenland (Godthab).
+#
+# The rest of Greenland, including Godthab (this area, although it
+# includes central Greenland, is known as west Greenland), keeps time
+# UTC-3, with daylight savings methods according to European rules.
+#
+# It is common procedure to use UTC 0 in the wilderness of East and
+# North Greenland, because it is mainly Icelandic aircraft operators
+# maintaining traffic in these areas.  However, the official status of
+# this area is that it sticks with Godthab time.  This area might be
+# considered a dual time zone in some respects because of this.
+# From Rives McDow (2001-11-19):
+# I heard back from someone stationed at Thule; the time change took place
+# there at 2:00 AM.
+# From Paul Eggert (2006-03-22):
+# From 1997 on the CIA map shows Danmarkshavn on GMT;
+# the 1995 map as like Godthab.
+# For lack of better info, assume they were like Godthab before 1996.
+# startkart.no says Thule does not observe DST, but this is clearly an error,
+# so go with Shanks & Pottenger for Thule transitions until this year.
+# For 2007 on assume Thule will stay in sync with US DST rules.

+# A discussion is running about the summer time efficiency and effect on

+# refers to the Eighth Directive and cites the association agreement between
+# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120).
+#
+# I also asked [my relative] whether they use any standard abbreviation

+# From <a href="http://www.baltictimes.com/">The Baltic Times</a> (1999-09-09)

+# Iceland
+#
+# From Adam David (1993-11-06):
+# The name of the timezone in Iceland for system / mail / news purposes is GMT.
+#
+# (1993-12-05):
+# This material is paraphrased from the 1988 edition of the University of
+# Iceland Almanak.
+#
+# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
+# behind GMT. Previously, local mean solar time was used in different parts
+# of Iceland, the almanak had been based on Reykjavik mean solar time which
+# was 1 hour and 28 minutes behind GMT.
+#
+# "first day of winter" referred to [below] means the first day of the 26 weeks
+# of winter, according to the old icelandic calendar that dates back to the
+# time the norsemen first settled Iceland.  The first day of winter is always
+# Saturday, but is not dependent on the Julian or Gregorian calendars.
+#
+# (1993-12-10):
+# I have a reference from the Oxford Icelandic-English dictionary for the
+# beginning of winter, which ties it to the ecclesiastical calendar (and thus
+# to the julian/gregorian calendar) over the period in question.
+#	the winter begins on the Saturday next before St. Luke's day
+#	(old style), or on St. Luke's day, if a Saturday.
+# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
+# might be a reference to the Julian calendar as opposed to Gregorian, or it
+# might mean something else (???).
+#
+# From Paul Eggert (2006-03-22):
+# The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points.
+# We go with the Almanak, except for one claim from Shanks & Pottenger, namely
+# that Reykavik was 21W57 from 1837 to 1908, local mean time before that.

+#
+# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
+# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24

+# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR,
+# Estonian SSR and Kaliningrad region of Russian Federation all year round the

+# The Regulations of the Cabinet of Ministers of the Republic of Latvia of

+# Last February the three Baltic states decided not to turn back their

+# From <a href="http://www.elta.lt/">ELTA</a> No. 972 (2582) (1999-09-29),
+# via Steffen Thorsen:
+# Lithuania has shifted back to the second time zone (GMT plus two hours)

+# as decided by the national government on Wednesday....
+# The Lithuanian government also announced plans to consider a
+# motion to give up shifting to summer time in spring, as it was

+# From the <a href="http://www.tourism.lt/informa/ff.htm">
+# Fact File, Lithuanian State Department of Tourism
+# </a> (2000-03-27): Local time is GMT+2 hours ..., no daylight saving.
+# From a user via Klaus Marten (2003-02-07):

+# observe Summer Time in 2003, changing its clocks at the times laid
+# down in EU Directive 2000/84 of 19.I.01 (i.e. at the same times as its

+# Netherlands
+# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
+# but for other purposes the Netherlands used Amsterdam mean time.
+# However, Robert H. van Gent writes (2001-04-01):
+# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
+# Amsterdam mean time) onwards, the whole of the Netherlands (including
+# the Dutch railways) was required by law to observe Amsterdam mean time
+# (19 minutes 32.13 seconds ahead of GMT). This had already been the
+# common practice (except for the railways) for many decades but it was
+# not until 1909 when the Dutch government finally defined this by law.
+# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
+# was generally known as Dutch Time ("Nederlandse Tijd").
+#
+# (2001-04-08):
+# 1892-05-01 was the date when the Dutch railways were by law required to
+# observe GMT while the remainder of the Netherlands adhered to the common
+# practice of following Amsterdam mean time.
+#
+# (2001-04-09):
+# In 1835 the authorities of the province of North Holland requested the
+# municipal authorities of the towns and cities in the province to observe
+# Amsterdam mean time but I do not know in how many cases this request was
+# actually followed.
+#
+# From 1852 onwards the Dutch telegraph offices were by law required to
+# observe Amsterdam mean time. As the time signals from the observatory of
+# Leiden were also distributed by the telegraph system, I assume that most
+# places linked up with the telegraph (and railway) system automatically
+# adopted Amsterdam mean time.
+#
+# Although the early Dutch railway companies initially observed a variety
+# of times, most of them had adopted Amsterdam mean time by 1858 but it
+# was not until 1866 when they were all required by law to observe
+# Amsterdam mean time.
+# The data before 1945 are taken from

+# Svalbard & Jan Mayen
+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway.  Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# http://www.lovdata.no/all/nl-19250717-011.html and
+# http://www.lovdata.no/all/nl-19300227-002.html).  The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabitated" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921.  Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+# From Paul Eggert (2001-05-01):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Oslo was
+# keeping Berlin time.
+#
+# <http://home.no.net/janmayen/history.htm> says that the meteorologists
+# burned down their station in 1940 and left the island, but returned in
+# 1941 with a small Norwegian garrison and continued operations despite
+# frequent air ttacks from Germans.  In 1943 the Americans established a
+# radiolocating station on the island, called "Atlantic City".  Possibly
+# the UTC offset changed during the war, but I think it unlikely that
+# Jan Mayen used German daylight-saving rules.
+#
+# Svalbard is more complicated, as it was raided in August 1941 by an
+# Allied party that evacuated the civilian population to England (says
+# <http://www.bartleby.com/65/sv/Svalbard.html>).  The Svalbard FAQ
+# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
+# expelled on 1942-05-14.  However, small parties of Germans did return,
+# and according to Wilhelm Dege's book "War North of 80" (1954)
+# <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html>
+# the German armed forces at the Svalbard weather station code-named
+# Haudegen did not surrender to the Allies until September 1945.
+#
+# All these events predate our cutoff date of 1970.  Unless we can
+# come up with more definitive info about the timekeeping during the
+# war years it's probably best just do do the following for now:

+# From Paul Eggert (2006-03-22):
+# Except for Moscow after 1919-07-01, I invented the time zone abbreviations.
+# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
+# are from Andrey A. Chernov.  The rest is from Shanks & Pottenger,
+# except we follow Chernov's report that 1992 DST transitions were Sat
+# 23:00, not Sun 02:00s.
+#
+# From Stanislaw A. Kuzikowski (1994-06-29):
+# But now it is some months since Novosibirsk is 3 hours ahead of Moscow!
+# I do not know why they have decided to make this change;
+# as far as I remember it was done exactly during winter->summer switching
+# so we (Novosibirsk) simply did not switch.
+#
+# From Andrey A. Chernov (1996-10-04):
+# `MSK' and `MSD' were born and used initially on Moscow computers with
+# UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
+# The next step was the UUCP network, the Relcom predecessor
+# (used mainly for mail), and MSK/MSD was actively used there.
+#
+# From Chris Carrier (1996-10-30):
+# According to a friend of mine who rode the Trans-Siberian Railroad from
+# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
+# still follows Moscow time, no matter where in Russia it is located.
+#
+# For Grozny, Chechnya, we have the following story from
+# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
+# News--often false--is spread by word of mouth.  A rumor that it was
+# time to move the clocks back put this whole city out of sync with
+# the rest of Russia for two weeks--even soldiers stationed here began
+# enforcing curfew at the wrong time.
+#
+# From Gwillim Law (2001-06-05):
+# There's considerable evidence that Sakhalin Island used to be in
+# UTC+11, and has changed to UTC+10, in this decade.  I start with the
+# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
+# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
+# since September 1997....  Although the Kuril Islands are

+# From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
+#
+# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
+# From the beginning of 1879 (that is 01-01 00:00) the time for all
+# places in the country is "the mean solar time for the meridian at
+# three degrees, or twelve minutes of time, to the west of the
+# meridian of the Observatory of Stockholm".  The law is dated 1878-05-31.
+#
+# The observatory at that time had the meridian 18 degrees 03' 30"
+# eastern longitude = 01:12:14 in time.  Less 12 minutes gives the
+# national standard time as 01:00:14 ahead of GMT....
+#
+# About the beginning of CET in Sweden. The lawtext ("Svensk
+# forfattningssamling 1899, no 44") states, that "from the beginning
+# of 1900... ... the same as the mean solar time for the meridian at
+# the distance of one hour of time from the meridian of the English
+# observatory at Greenwich, or at 12 minutes 14 seconds to the west
+# from the meridian of the Observatory of Stockholm". The law is dated
+# 1899-06-16.  In short: At 1900-01-01 00:00:00 the new standard time
+# in Sweden is 01:00:00 ahead of GMT.
+#
+# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
+# that "1916-05-15 is considered to begin one hour earlier". It is
+# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
+# Further the law says, that "1916-09-30 is considered to end one hour later".
+#
+# The laws regulating [DST] are available on the site of the Swedish
+# Parliament beginning with 1985 - the laws regulating 1980/1984 are
+# not available on the site (to my knowledge they are only available
+# in Swedish): <http://www.riksdagen.se/english/work/sfst.asp> (type
+# "sommartid" without the quotes in the field "Fritext" and then click

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

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

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

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