  77. # Britain (United Kingdom) and Ireland (Eire)
  78. # From Peter Ilieve (1994-07-06):
  79. #
  80. # On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
  81. # historical vistas along the Thames in west London. There was a photo
  82. # and a sketch map showing some of the sightlines involved. One paragraph
  83. # of the text said:
  84. #
  85. # `An old stone obelisk marking a forgotten terrestrial meridian stands
  86. # beside the river at Kew. In the 18th century, before time and longitude
  87. # was standardised by the Royal Observatory in Greenwich, scholars observed
  88. # this stone and the movement of stars from Kew Observatory nearby. They
  89. # made their calculations and set the time for the Horse Guards and Parliament,
  90. # but now the stone is obscured by scrubwood and can only be seen by walking
  91. # along the towpath within a few yards of it.'
  92. #
  93. # I have a one inch to one mile map of London and my estimate of the stone's
  94. # position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
  95. # be within about +-2". The Ordnance Survey grid reference is TQ172761.
  96. #
  97. # [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
  98. # From Paul Eggert (1993-11-18):
  99. #
  100. # Howse writes that Britain was the first country to use standard time.
  101. # The railways cared most about the inconsistencies of local mean time,
  102. # and it was they who forced a uniform time on the country.
  103. # The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
  104. # and was popularized by Abraham Follett Osler (1808-1903).
  105. # The first railway to adopt London time was the Great Western Railway
  106. # in November 1840; other railways followed suit, and by 1847 most
  107. # (though not all) railways used London time. On 1847-09-22 the
  108. # Railway Clearing House, an industry standards body, recommended that GMT be
  109. # adopted at all stations as soon as the General Post Office permitted it.
  110. # The transition occurred on 12-01 for the L&NW, the Caledonian,
  111. # and presumably other railways; the January 1848 Bradshaw's lists many
  112. # railways as using GMT. By 1855 the vast majority of public
  113. # clocks in Britain were set to GMT (though some, like the great clock
  114. # on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
  115. # one for local time and one for GMT). The last major holdout was the legal
  116. # system, which stubbornly stuck to local time for many years, leading
  117. # to oddities like polls opening at 08:13 and closing at 16:13.
  118. # The legal system finally switched to GMT when the Statutes (Definition
  119. # of Time) Act took effect; it received the Royal Assent on 1880-08-02.
  120. #
  121. # In the tables below, we condense this complicated story into a single
  122. # transition date for London, namely 1847-12-01. We don't know as much
  123. # about Dublin, so we use 1880-08-02, the legal transition time.
  124. # From Paul Eggert (2003-09-27):
  125. # Summer Time was first seriously proposed by William Willett (1857-1915),
  126. # a London builder and member of the Royal Astronomical Society
  127. # who circulated a pamphlet ``The Waste of Daylight'' (1907)
  128. # that proposed advancing clocks 20 minutes on each of four Sundays in April,
  129. # and retarding them by the same amount on four Sundays in September.
  130. # A bill was drafted in 1909 and introduced in Parliament several times,
  131. # but it met with ridicule and opposition, especially from farming interests.

  135. # A monument to Willett was unveiled on 1927-05-21, in an open space in
  136. # a 45-acre wood near Chislehurst, Kent that was purchased by popular
  137. # subscription and open to the public. On the south face of the monolith,
  138. # designed by G. W. Miller, is the...William Willett Memorial Sundial,
  139. # which is permanently set to Summer Time.
  140. # From Winston Churchill (1934-04-28):
  141. # It is one of the paradoxes of history that we should owe the boon of
  142. # summer time, which gives every year to the people of this country
  143. # between 160 and 170 hours more daylight leisure, to a war which
  144. # plunged Europe into darkness for four years, and shook the
  145. # foundations of civilization throughout the world.

  210. #
  211. # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
  212. #
  213. # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
  214. # are incorrect:
  215. # * Wales did not switch from GMT to daylight saving time until
  216. # 1921 Apr 3, when they began to conform with the rest of Great Britain.
  217. # Actually, Wales was identical after 1880.
  218. # * Eire had two transitions on 1916 Oct 1.
  219. # It actually just had one transition.
  220. # * Northern Ireland used single daylight saving time throughout WW II.
  221. # Actually, it conformed to Britain.
  222. # * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
  223. # Actually, that date saw the usual switch to summer time.
  224. # Standard time was not changed until 1968-10-27 (the clocks didn't change).
  225. #
  226. # Here is another incorrect claim by Shanks & Pottenger:
  227. # * Jersey, Guernsey, and the Isle of Man did not switch from GMT
  228. # to daylight saving time until 1921 Apr 3, when they began to
  229. # conform with Great Britain.
  230. # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
  231. #
  232. # The following claim by Shanks & Pottenger is possible though doubtful;
  233. # we'll ignore it for now.
  234. # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
  235. #
  236. #
  237. # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
  238. # Shanks & Pottenger.
  239. # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
  240. # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
  241. # to London. For example:
  242. #
  243. # "Timeball on the ballast office is down. Dunsink time."

  280. # My admittedly uninformed guess is that the terminal has two authorities,
  281. # the French concession operators and the British civil authorities,
  282. # and that the time depends on who you're talking to.
  283. # If, say, the British police were called to the station for some reason,

  787. # From Jesper Norgaard Welen (2005-04-26):
  788. # http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
  789. # [introducing standard time] was in effect from 1894-01-01....
  790. # The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
  791. # confirms this, and states that the law was put forth 1893-03-29.
  792. #
  793. # The EU treaty with effect from 1973:
  794. # http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
  795. #
  796. # This provoked a new law from 1974 to make possible summer time changes
  797. # in subsequenet decrees with the law
  798. # http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
  799. #
  800. # It seems however that no decree was set forward until 1980. I have
  801. # not found any decree, but in another related law, the effecting DST
  802. # changes are stated explicitly to be from 1980-04-06 at 02:00 to
  803. # 1980-09-28 at 02:00. If this is true, this differs slightly from
  804. # the EU rule in that DST runs to 02:00, not 03:00. We don't know
  805. # when Denmark began using the EU rule correctly, but we have only
  806. # confirmation of the 1980-time, so I presume it was correct in 1981:
  807. # The law is about the management of the extra hour, concerning
  808. # working hours reported and effect on obligatory-rest rules (which
  809. # was suspended on that night):
  810. # http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL

  812. # The Herning Folkeblad (1980-09-26) reported that the night between
  813. # Saturday and Sunday the clock is set back from three to two.
  814. # From Paul Eggert (2005-06-11):
  815. # Hence the "02:00" of the 1980 law refers to standard time, not

  847. # Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
  848. # and left the EU on 1985-02-01. It therefore should have been using EU
  849. # rules at least through 1984. Shanks & Pottenger say Scoresbysund and Godthab
  850. # used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
  851. # rules since at least 1991. Assume EU rules since 1980.
  852. # From Gwillin Law (2001-06-06), citing
  853. # <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
  854. # and with translations corrected by Steffen Thorsen:
  855. #
  856. # Greenland has four local times, and the relation to UTC
  857. # is according to the following time line:
  858. #
  859. # The military zone near Thule UTC-4
  860. # Standard Greenland time UTC-3
  861. # Scoresbysund UTC-1
  862. # Danmarkshavn UTC
  863. #
  864. # In the military area near Thule and in Danmarkshavn DST will not be
  865. # introduced.
  866. # From Rives McDow (2001-11-01):
  867. #
  868. # I correspond regularly with the Dansk Polarcenter, and wrote them at
  869. # the time to clarify the situation in Thule. Unfortunately, I have
  870. # not heard back from them regarding my recent letter. [But I have
  871. # info from earlier correspondence.]
  872. #
  873. # According to the center, a very small local time zone around Thule
  874. # Air Base keeps the time according to UTC-4, implementing daylight
  875. # savings using North America rules, changing the time at 02:00 local time....
  876. #
  877. # The east coast of Greenland north of the community of Scoresbysund
  878. # uses UTC in the same way as in Iceland, year round, with no dst.
  879. # There are just a few stations on this coast, including the
  880. # Danmarkshavn ICAO weather station mentioned in your September 29th
  881. # email. The other stations are two sledge patrol stations in
  882. # Mestersvig and Daneborg, the air force base at Station Nord, and the
  883. # DPC research station at Zackenberg.
  884. #
  885. # Scoresbysund and two small villages nearby keep time UTC-1 and use
  886. # the same daylight savings time period as in West Greenland (Godthab).
  887. #
  888. # The rest of Greenland, including Godthab (this area, although it
  889. # includes central Greenland, is known as west Greenland), keeps time
  890. # UTC-3, with daylight savings methods according to European rules.
  891. #
  892. # It is common procedure to use UTC 0 in the wilderness of East and
  893. # North Greenland, because it is mainly Icelandic aircraft operators
  894. # maintaining traffic in these areas. However, the official status of
  895. # this area is that it sticks with Godthab time. This area might be
  896. # considered a dual time zone in some respects because of this.
  897. # From Rives McDow (2001-11-19):
  898. # I heard back from someone stationed at Thule; the time change took place
  899. # there at 2:00 AM.
  900. # From Paul Eggert (2006-03-22):
  901. # From 1997 on the CIA map shows Danmarkshavn on GMT;
  902. # the 1995 map as like Godthab.
  903. # For lack of better info, assume they were like Godthab before 1996.
  904. # startkart.no says Thule does not observe DST, but this is clearly an error,
  905. # so go with Shanks & Pottenger for Thule transitions until this year.

  1227. # Iceland
  1228. #
  1229. # From Adam David (1993-11-06):
  1230. # The name of the timezone in Iceland for system / mail / news purposes is GMT.
  1231. #
  1232. # (1993-12-05):
  1233. # This material is paraphrased from the 1988 edition of the University of
  1234. # Iceland Almanak.
  1235. #
  1236. # From January 1st, 1908 the whole of Iceland was standardised at 1 hour
  1237. # behind GMT. Previously, local mean solar time was used in different parts
  1238. # of Iceland, the almanak had been based on Reykjavik mean solar time which
  1239. # was 1 hour and 28 minutes behind GMT.
  1240. #
  1241. # "first day of winter" referred to [below] means the first day of the 26 weeks
  1242. # of winter, according to the old icelandic calendar that dates back to the
  1243. # time the norsemen first settled Iceland. The first day of winter is always
  1244. # Saturday, but is not dependent on the Julian or Gregorian calendars.
  1245. #
  1246. # (1993-12-10):
  1247. # I have a reference from the Oxford Icelandic-English dictionary for the
  1248. # beginning of winter, which ties it to the ecclesiastical calendar (and thus
  1249. # to the julian/gregorian calendar) over the period in question.
  1250. # the winter begins on the Saturday next before St. Luke's day
  1251. # (old style), or on St. Luke's day, if a Saturday.
  1252. # St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
  1253. # might be a reference to the Julian calendar as opposed to Gregorian, or it
  1254. # might mean something else (???).
  1255. #
  1256. # From Paul Eggert (2006-03-22):
  1257. # The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points.
  1258. # We go with the Almanak, except for one claim from Shanks & Pottenger, namely
  1259. # that Reykavik was 21W57 from 1837 to 1908, local mean time before that.

  1539. # From Paul Eggert (2006-03-22):
  1540. # A previous version of this database followed Shanks & Pottenger, who write
  1541. # that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
  1542. # However, this is most likely an error, as Moldova declared independence
  1543. # on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
  1544. # In early 1992 there was large-scale interethnic violence in the area
  1545. # and it's possible that some Russophones continued to observe Moscow time.
  1546. # But [two people] separately reported via
  1547. # Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.
  1548. # The Tiraspol entry has therefore been removed for now.

  1622. # 1892-05-01 was the date when the Dutch railways were by law required to
  1623. # observe GMT while the remainder of the Netherlands adhered to the common
  1624. # practice of following Amsterdam mean time.
  1625. #
  1626. # (2001-04-09):
  1627. # In 1835 the authorities of the province of North Holland requested the
  1628. # municipal authorities of the towns and cities in the province to observe
  1629. # Amsterdam mean time but I do not know in how many cases this request was
  1630. # actually followed.
  1631. #
  1632. # From 1852 onwards the Dutch telegraph offices were by law required to
  1633. # observe Amsterdam mean time. As the time signals from the observatory of
  1634. # Leiden were also distributed by the telegraph system, I assume that most
  1635. # places linked up with the telegraph (and railway) system automatically
  1636. # adopted Amsterdam mean time.
  1637. #
  1638. # Although the early Dutch railway companies initially observed a variety
  1639. # of times, most of them had adopted Amsterdam mean time by 1858 but it
  1640. # was not until 1866 when they were all required by law to observe
  1641. # Amsterdam mean time.

  1694. # Svalbard & Jan Mayen
  1695. # From Steffen Thorsen (2001-05-01):
  1696. # Although I could not find it explicitly, it seems that Jan Mayen and
  1697. # Svalbard have been using the same time as Norway at least since the
  1698. # time they were declared as parts of Norway. Svalbard was declared
  1699. # as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
  1700. # Mayen by law of 1930-02-27 no 2, section 2. (From
  1701. # http://www.lovdata.no/all/nl-19250717-011.html and
  1702. # http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation
  1703. # for normal/standard time in Norway is from 1894-06-29 no 1 (came
  1704. # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
  1705. # part of this law since 1925/1930. (From
  1706. # http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
  1707. # able to find if Jan Mayen used a different time zone (e.g. -0100)
  1708. # before 1930. Jan Mayen has only been "inhabitated" since 1921 by
  1709. # Norwegian meteorologists and maybe used the same time as Norway ever
  1710. # since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
  1711. # before 1895, and therefore probably changed the local time somewhere
  1712. # between 1895 and 1925 (inclusive).
  1713. # From Paul Eggert (2001-05-01):
  1714. #
  1715. # Actually, Jan Mayen was never occupied by Germany during World War II,
  1716. # so it must have diverged from Oslo time during the war, as Oslo was
  1717. # keeping Berlin time.
  1718. #
  1719. # <http://home.no.net/janmayen/history.htm> says that the meteorologists
  1720. # burned down their station in 1940 and left the island, but returned in
  1721. # 1941 with a small Norwegian garrison and continued operations despite
  1722. # frequent air ttacks from Germans. In 1943 the Americans established a
  1723. # radiolocating station on the island, called "Atlantic City". Possibly
  1724. # the UTC offset changed during the war, but I think it unlikely that
  1725. # Jan Mayen used German daylight-saving rules.
  1726. #
  1727. # Svalbard is more complicated, as it was raided in August 1941 by an
  1728. # Allied party that evacuated the civilian population to England (says
  1729. # <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ
  1730. # <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
  1731. # expelled on 1942-05-14. However, small parties of Germans did return,
  1732. # and according to Wilhelm Dege's book "War North of 80" (1954)
  1733. # <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html>
  1734. # the German armed forces at the Svalbard weather station code-named
  1735. # Haudegen did not surrender to the Allies until September 1945.
  1736. #
  1737. # All these events predate our cutoff date of 1970. Unless we can
  1738. # come up with more definitive info about the timekeeping during the
  1739. # war years it's probably best just do...the following for now:

  1914. # From Paul Eggert (2006-03-22):
  1915. # Except for Moscow after 1919-07-01, I invented the time zone abbreviations.
  1916. # Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
  1917. # are from Andrey A. Chernov. The rest is from Shanks & Pottenger,
  1918. # except we follow Chernov's report that 1992 DST transitions were Sat
  1919. # 23:00, not Sun 02:00s.
  1920. #
  1921. # From Stanislaw A. Kuzikowski (1994-06-29):
  1922. # But now it is some months since Novosibirsk is 3 hours ahead of Moscow!
  1923. # I do not know why they have decided to make this change;
  1924. # as far as I remember it was done exactly during winter->summer switching
  1925. # so we (Novosibirsk) simply did not switch.
  1926. #
  1927. # From Andrey A. Chernov (1996-10-04):
  1928. # `MSK' and `MSD' were born and used initially on Moscow computers with
  1929. # UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
  1930. # The next step was the UUCP network, the Relcom predecessor
  1931. # (used mainly for mail), and MSK/MSD was actively used there.
  1932. #
  1933. # From Chris Carrier (1996-10-30):
  1934. # According to a friend of mine who rode the Trans-Siberian Railroad from
  1935. # Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
  1936. # still follows Moscow time, no matter where in Russia it is located.
  1937. #
  1938. # For Grozny, Chechnya, we have the following story from
  1939. # John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
  1940. # News--often false--is spread by word of mouth. A rumor that it was
  1941. # time to move the clocks back put this whole city out of sync with
  1942. # the rest of Russia for two weeks--even soldiers stationed here began
  1943. # enforcing curfew at the wrong time.
  1944. #
  1945. # From Gwillim Law (2001-06-05):
  1946. # There's considerable evidence that Sakhalin Island used to be in
  1947. # UTC+11, and has changed to UTC+10, in this decade. I start with the
  1948. # SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
  1949. # until February 1997, and then in RU9 with Khabarovsk and Vladivostok
  1950. # since September 1997.... Although the Kuril Islands are
  1951. # administratively part of Sakhalin oblast', they appear to have
  1952. # remained on UTC+11 along with Magadan.

  2280. # From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
  2281. #
  2282. # The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
  2283. # From the beginning of 1879 (that is 01-01 00:00) the time for all
  2284. # places in the country is "the mean solar time for the meridian at
  2285. # three degrees, or twelve minutes of time, to the west of the
  2286. # meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
  2287. #
  2288. # The observatory at that time had the meridian 18 degrees 03' 30"
  2289. # eastern longitude = 01:12:14 in time. Less 12 minutes gives the
  2290. # national standard time as 01:00:14 ahead of GMT....
  2291. #
  2292. # About the beginning of CET in Sweden. The lawtext ("Svensk
  2293. # forfattningssamling 1899, no 44") states, that "from the beginning
  2294. # of 1900... ... the same as the mean solar time for the meridian at
  2295. # the distance of one hour of time from the meridian of the English
  2296. # observatory at Greenwich, or at 12 minutes 14 seconds to the west
  2297. # from the meridian of the Observatory of Stockholm". The law is dated
  2298. # 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
  2299. # in Sweden is 01:00:00 ahead of GMT.
  2300. #
  2301. # 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
  2302. # that "1916-05-15 is considered to begin one hour earlier". It is
  2303. # pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
  2304. # Further the law says, that "1916-09-30 is considered to end one hour later".
  2305. #
  2306. # The laws regulating [DST] are available on the site of the Swedish
  2307. # Parliament beginning with 1985 - the laws regulating 1980/1984 are

  2316. # summertime the church-clocks etc were set back one hour to show
  2317. # 1916-10-01 00:00 standard time. The article also reports that some

  2342. # From Alois Treindl (2008-12-17):
  2343. # I have researched the DST usage in Switzerland during the 1940ies.
  2344. #
  2345. # As I wrote in an earlier message, I suspected the current tzdata values
  2346. # to be wrong. This is now verified.
  2347. #
  2348. # I have found copies of the original ruling by the Swiss Federal
  2349. # government, in 'Eidgen[o]ssische Gesetzessammlung 1941 and 1942' (Swiss
  2350. # federal law collection)...
  2351. #
  2352. # DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
  2353. # DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
  2354. #
  2355. # DST began on Monday, 4 May 1942 at 01:00 am
  2356. # DST ended on Monday, 5 Oct 1942 at 02:00 am
  2357. #
  2358. # There was no DST in 1940, I have checked the law collection carefully.
  2359. # It is also indicated by the fact that the 1942 entry in the law
  2360. # collection points back to 1941 as a reference, but no reference to any
  2361. # other years are made.
  2362. #
  2363. # Newspaper articles I have read in the archives on 6 May 1941 reported
  2364. # about the introduction of DST (Sommerzeit in German) during the previous
  2365. # night as an absolute novelty, because this was the first time that such
  2366. # a thing had happened in Switzerland.
  2367. #
  2368. # I have also checked 1916, because one book source (Gabriel, Traite de
  2369. # l'heure dans le monde) claims that Switzerland had DST in 1916. This is
  2370. # false, no official document could be found. Probably Gabriel got misled
  2371. # by references to Germany, which introduced DST in 1916 for the first time.
  2372. #
  2373. # The tzdata rules for Switzerland must be changed to:
  2374. # Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S
  2375. # Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 -

  2639. # ...the European time rules are...standardized since 1981, when
  2640. # most European coun[tr]ies started DST. Before that year, only
  2641. # a few countries (UK, France, Italy) had DST, each according
  2642. # to own national rules. In 1981, however, DST started on
  2643. # 'Apr firstSun', and not on 'Mar lastSun' as in the following
  2644. # years...
  2645. # But also since 1981 there are some more national exceptions
  2646. # than listed in 'europe': Switzerland, for example, joined DST
  2647. # one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
  2648. # lastSun' in 1981---I don't know how they handle now.
  2649. #
  2650. # Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
  2651. # Soviet Union (as far as I know).

  2661. # The information from Tom Hofmann is (as far as I know) not entirely correct.
  2662. # After a request from chongo at amdahl I tried to retrieve all information
  2663. # about DST in Europe. I was able to find all from about 1969.
  2664. #
  2665. # ...standardization on DST in Europe started in about 1977 with switches on
  2666. # first Sunday in April and last Sunday in September...
  2667. # In 1981 UK joined Europe insofar that
  2668. # the starting day for both shifted to last Sunday in March. And from 1982
  2669. # the whole of Europe used DST, with switch dates April 1 and October 1 in
  2670. # the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
  2671. # dates...
  2672. #
  2673. # It should also be remembered that time-zones are not constants; e.g.
  2674. # Portugal switched in 1976 from MET (or CET) to WET with DST...
  2675. # Note also that though there were rules for switch dates not
  2676. # all countries abided to these dates, and many individual deviations
  2677. # occurred, though not since 1982 I believe. Another note: it is always
  2678. # assumed that DST is 1 hour ahead of normal time, this need not be the
  2679. # case; at least in the Netherlands there have been times when DST was 2 hours
  2680. # in advance of normal time.
