# 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.

|
|
|
|
# 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.

# 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.

|
|

# 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

|
|
|
|
# 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">

|
|
|
|
# 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."

|
# 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,

|
|
# 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.

|
|
# 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

# <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.

# 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.

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

# From Paul Eggert (2006-03-22):

|
# A previous version of this database followed Shanks & Pottenger, who write
|
|
# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
|
|
# However, this is most likely an error, as Moldova declared independence
|
|
# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
|
|
# In early 1992 there was large-scale interethnic violence in the area
|
|
# and it's possible that some Russophones continued to observe Moscow time.
|
|
# But [two people] separately reported via
|
|
# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.
|
|
# The Tiraspol entry has therefore been removed for now.

# 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.

# 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:

# Russia
|
|
|
|
# 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
|
|
# administratively part of Sakhalin oblast', they appear to have
|
|
# remained on UTC+11 along with Magadan.

|
# 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
|

# the Sok-button).
|
|
#
|
|
# (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.

# From Alois Treindl (2008-12-17):
|
|
# I have researched the DST usage in Switzerland during the 1940ies.
|
|
#
|
|
# As I wrote in an earlier message, I suspected the current tzdata values
|
|
# to be wrong. This is now verified.
|
|
#
|
|
# I have found copies of the original ruling by the Swiss Federal
|
|
# government, in 'Eidgen[o]ssische Gesetzessammlung 1941 and 1942' (Swiss
|
|
# federal law collection)...
|
|
#
|
|
# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
|
|
# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
|
|
#
|
|
# DST began on Monday, 4 May 1942 at 01:00 am
|
|
# DST ended on Monday, 5 Oct 1942 at 02:00 am
|
|
#
|
|
# There was no DST in 1940, I have checked the law collection carefully.
|
|
# It is also indicated by the fact that the 1942 entry in the law
|
|
# collection points back to 1941 as a reference, but no reference to any
|
|
# other years are made.
|
|
#
|
|
# Newspaper articles I have read in the archives on 6 May 1941 reported
|
|
# about the introduction of DST (Sommerzeit in German) during the previous
|
|
# night as an absolute novelty, because this was the first time that such
|
|
# a thing had happened in Switzerland.
|
|
#
|
|
# I have also checked 1916, because one book source (Gabriel, Traite de
|
|
# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
|
|
# false, no official document could be found. Probably Gabriel got misled
|
|
# by references to Germany, which introduced DST in 1916 for the first time.
|
|
#
|
|
# The tzdata rules for Switzerland must be changed to:
|
|
# Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S
|
|
# Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 -

# According to Bernard Sieloff's source, Poland is in the MET time zone but

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

# switches on the same day, but switches on at 01:00 standard time

# ...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.
