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

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

234 234
235 235 # From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
236 236 # [N]o official designation has as far as I know been adopted for the time
237 237 # which is to be introduced in May....
238 238 # I cannot think of anything better than "Double British Summer Time"
239 239 # which could not be said to run counter to any official description.
240 240
241 241 # From Paul Eggert (2000-10-02):
242 242 # Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common
243 243 # and follows the more usual convention of putting the location name first,
244 244 # so we use 'BDST'.

246 246 # Peter Ilieve (1998-04-19) described at length

250 250 # http://www.polyomino.org.uk/british-time/
251 251
252 252 # From Joseph S. Myers (1998-01-06):
253 253 #
254 254 # The legal time in the UK outside of summer time is definitely GMT, not UTC;
255 255 # see Lord Tanlaw's speech
256 256 # http://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0

258 258
259 259 # From Paul Eggert (2006-03-22):
260 260 #
261 261 # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
262 262 #
263 263 # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
264 264 # are incorrect:
265 265 # * Wales did not switch from GMT to daylight saving time until
266 266 # 1921 Apr 3, when they began to conform with the rest of Great Britain.
267 267 # Actually, Wales was identical after 1880.
268 268 # * Eire had two transitions on 1916 Oct 1.
269 269 # It actually just had one transition.
270 270 # * Northern Ireland used single daylight saving time throughout WW II.
271 271 # Actually, it conformed to Britain.
272 272 # * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
273 273 # Actually, that date saw the usual switch to summer time.
274 274 # Standard time was not changed until 1968-10-27 (the clocks didn't change).
275 275 #
276 276 # Here is another incorrect claim by Shanks & Pottenger:
277 277 # * Jersey, Guernsey, and the Isle of Man did not switch from GMT
278 278 # to daylight saving time until 1921 Apr 3, when they began to
279 279 # conform with Great Britain.
280 280 # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
281 281 #
282 282 # The following claim by Shanks & Pottenger is possible though doubtful;
283 283 # we'll ignore it for now.
284 284 # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
285 285 #
286 286 #
287 287 # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
288 288 # Shanks & Pottenger.
289 289 # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
290 290 # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
291 291 # to London. For example:

335 335 # reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
336 336 # (CT), equivalent to French civil time.
337 337 # Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
338 338 # trains between Dollands Moor (the freight facility next door)
339 339 # and Frethun run in CT.
340 340 # My admittedly uninformed guess is that the terminal has two authorities,
341 341 # the French concession operators and the British civil authorities,
342 342 # and that the time depends on who you're talking to.
343 343 # If, say, the British police were called to the station for some reason,
344 344 # I would expect the official police report to use GMT/BST and not CET/CEST.
345 345 # This is a borderline case, but for now let's stick to GMT/BST.

347 347 # From an anonymous contributor (1996-06-02):
348 348 # The law governing time in Ireland is under Statutory Instrument SI 395/94,
349 349 # which gives force to European Union 7th Council Directive No. 94/21/EC.
350 350 # Under this directive, the Minister for Justice in Ireland makes appropriate
351 351 # regulations. I spoke this morning with the Secretary of the Department of
352 352 # Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
353 353 # "Irish Summer Time", abbreviated to "IST".

614 +# Wikipedia and other sources refer to the Act of the Council of
615 +# Ministers of the USSR from 1988-01-04 No. 5 and the Act of the
616 +# Council of Ministers of the USSR from 1989-03-14 No. 227.
617 +#
618 +# I did not find full texts of these acts. For the 1989 one we have
619 +# title at http://base.garant.ru/70754136/ :
620 +# "About change in calculation of time on the territories of
621 +# Lithuanian SSR, Latvian SSR and Estonian SSR, Astrakhan,
622 +# Kaliningrad, Kirov, Kuybyshev, Ulyanovsk and Uralsk oblasts".
623 +# And http://astrozet.net/files/Zones/DOC/RU/1980-925.txt appears to
624 +# contain quotes from both acts: Since last Sunday of March 1988 rules
625 +# of the second time belt are installed in Volgograd and Saratov
626 +# oblasts. Since last Sunday of March 1989:
627 +# a) Lithuanian SSR, Latvian SSR, Estonian SSR, Kaliningrad oblast:
628 +# second time belt rules without extra hour (Moscow-1);
629 +# b) Astrakhan, Kirov, Kuybyshev, Ulyanovsk oblasts: second time belt
630 +# rules (Moscow time)
631 +# c) Uralsk oblast: third time belt rules (Moscow+1).

884 904 # The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL

893 913 #
894 914 # It seems however that no decree was set forward until 1980. I have
895 915 # not found any decree, but in another related law, the effecting DST
896 916 # changes are stated explicitly to be from 1980-04-06 at 02:00 to
897 917 # 1980-09-28 at 02:00. If this is true, this differs slightly from
898 918 # the EU rule in that DST runs to 02:00, not 03:00. We don't know
899 919 # when Denmark began using the EU rule correctly, but we have only
900 920 # confirmation of the 1980-time, so I presume it was correct in 1981:

954 974 # Greenland has four local times, and the relation to UTC

957 977 # The military zone near Thule UTC-4

969 989 # not heard back from them regarding my recent letter. [But I have
970 990 # info from earlier correspondence.]
971 991 #
972 992 # According to the center, a very small local time zone around Thule
973 993 # Air Base keeps the time according to UTC-4, implementing daylight
974 994 # savings using North America rules, changing the time at 02:00 local time....
975 995 #
976 996 # The east coast of Greenland north of the community of Scoresbysund
977 997 # uses UTC in the same way as in Iceland, year round, with no dst.
978 998 # There are just a few stations on this coast, including the
979 999 # Danmarkshavn ICAO weather station mentioned in your September 29th
980 1000 # email. The other stations are two sledge patrol stations in
981 1001 # Mestersvig and Daneborg, the air force base at Station Nord, and the
982 1002 # DPC research station at Zackenberg.
983 1003 #
984 1004 # Scoresbysund and two small villages nearby keep time UTC-1 and use
985 1005 # the same daylight savings time period as in West Greenland (Godthåb).
986 1006 #
987 1007 # The rest of Greenland, including Godthåb (this area, although it
988 1008 # includes central Greenland, is known as west Greenland), keeps time
989 1009 # UTC-3, with daylight savings methods according to European rules.
990 1010 #
991 1011 # It is common procedure to use UTC 0 in the wilderness of East and
992 1012 # North Greenland, because it is mainly Icelandic aircraft operators
993 1013 # maintaining traffic in these areas. However, the official status of
994 1014 # this area is that it sticks with Godthåb time. This area might be

1445 1475 # Sicily and Sardinia each had their own time zones from 1866 to 1893,
1446 1476 # called Palermo Time (+00:53:28) and Cagliari Time (+00:36:32).
1447 1477 # During World War II, German-controlled Italy used German time.
1448 1478 # But these events all occurred before the 1970 cutoff,
1449 1479 # so record only the time in Rome.

1767 +# ... says that since 1990-05-06 on the territory of the Moldavian SSR
1768 +# time would be calculated as the standard time of the second time belt

1733 1776 # that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1734 1777 # However, this is most likely an error, as Moldova declared independence
1735 1778 # on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1736 1779 # In early 1992 there was large-scale interethnic violence in the area
1737 1780 # and it's possible that some Russophones continued to observe Moscow time.
1738 1781 # But [two people] separately reported via
1739 1782 # Jesper Nørgaard that as of 2001-01-24 Tiraspol was like Chisinau.

1816 1857 # Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
1817 1858 # Amsterdam mean time) onwards, the whole of the Netherlands (including
1818 1859 # the Dutch railways) was required by law to observe Amsterdam mean time
1819 1860 # (19 minutes 32.13 seconds ahead of GMT). This had already been the
1820 1861 # common practice (except for the railways) for many decades but it was
1821 1862 # not until 1909 when the Dutch government finally defined this by law.
1822 1863 # On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
1823 1864 # was generally known as Dutch Time ("Nederlandse Tijd").
1824 1865 #
1825 1866 # (2001-04-08):
1826 1867 # 1892-05-01 was the date when the Dutch railways were by law required to
1827 1868 # observe GMT while the remainder of the Netherlands adhered to the common
1828 1869 # practice of following Amsterdam mean time.
1829 1870 #
1830 1871 # (2001-04-09):
1831 1872 # In 1835 the authorities of the province of North Holland requested the
1832 1873 # municipal authorities of the towns and cities in the province to observe
1833 1874 # Amsterdam mean time but I do not know in how many cases this request was
1834 1875 # actually followed.
1835 1876 #
1836 1877 # From 1852 onwards the Dutch telegraph offices were by law required to
1837 1878 # observe Amsterdam mean time. As the time signals from the observatory of
1838 1879 # Leiden were also distributed by the telegraph system, I assume that most
1839 1880 # places linked up with the telegraph (and railway) system automatically
1840 1881 # adopted Amsterdam mean time.
1841 1882 #
1842 1883 # Although the early Dutch railway companies initially observed a variety
1843 1884 # of times, most of them had adopted Amsterdam mean time by 1858 but it
1844 1885 # was not until 1866 when they were all required by law to observe

1903 1944
1904 1945 # From Steffen Thorsen (2001-05-01):
1905 1946 # Although I could not find it explicitly, it seems that Jan Mayen and
1906 1947 # Svalbard have been using the same time as Norway at least since the
1907 1948 # time they were declared as parts of Norway. Svalbard was declared
1908 1949 # as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
1909 1950 # Mayen by law of 1930-02-27 no 2, section 2. (From
1910 1951 # <http://www.lovdata.no/all/nl-19250717-011.html> and
1911 1952 # <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
1912 1953 # for normal/standard time in Norway is from 1894-06-29 no 1 (came
1913 1954 # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
1914 1955 # part of this law since 1925/1930. (From
1915 1956 # <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
1916 1957 # able to find if Jan Mayen used a different time zone (e.g. -0100)
1917 1958 # before 1930. Jan Mayen has only been "inhabited" since 1921 by
1918 1959 # Norwegian meteorologists and maybe used the same time as Norway ever
1919 1960 # since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
1920 1961 # before 1895, and therefore probably changed the local time somewhere
1921 1962 # between 1895 and 1925 (inclusive).
1922 1963
1923 1964 # From Paul Eggert (2013-09-04):
1924 1965 #
1925 1966 # Actually, Jan Mayen was never occupied by Germany during World War II,
1926 1967 # so it must have diverged from Oslo time during the war, as Oslo was
1927 1968 # keeping Berlin time.
1928 1969 #
1929 1970 # <http://home.no.net/janmayen/history.htm> says that the meteorologists
1930 1971 # burned down their station in 1940 and left the island, but returned in
1931 1972 # 1941 with a small Norwegian garrison and continued operations despite
1932 1973 # frequent air attacks from Germans. In 1943 the Americans established a
1933 1974 # radiolocating station on the island, called "Atlantic City". Possibly
1934 1975 # the UT offset changed during the war, but I think it unlikely that
1935 1976 # Jan Mayen used German daylight-saving rules.
1936 1977 #
1937 1978 # Svalbard is more complicated, as it was raided in August 1941 by an
1938 1979 # Allied party that evacuated the civilian population to England (says

1940 1981 # <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
1941 1982 # expelled on 1942-05-14. However, small parties of Germans did return,
1942 1983 # and according to Wilhelm Dege's book "War North of 80" (1954)

2237 2278 # John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
2238 2279 # News - often false - is spread by word of mouth. A rumor that it was
2239 2280 # time to move the clocks back put this whole city out of sync with
2240 2281 # the rest of Russia for two weeks - even soldiers stationed here began
2241 2282 # enforcing curfew at the wrong time.
2242 2283 #
2243 2284 # From Gwillim Law (2001-06-05):
2244 2285 # There's considerable evidence that Sakhalin Island used to be in
2245 2286 # UTC+11, and has changed to UTC+10, in this decade. I start with the
2246 2287 # SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
2247 2288 # until February 1997, and then in RU9 with Khabarovsk and Vladivostok
2248 2289 # since September 1997.... Although the Kuril Islands are
2249 2290 # administratively part of Sakhalin oblast', they appear to have
2250 2291 # remained on UTC+11 along with Magadan.

2947 3226 # From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
2948 3227 #
2949 3228 # The law "Svensk författningssamling 1878, no 14" about standard time in 1879:
2950 3229 # From the beginning of 1879 (that is 01-01 00:00) the time for all
2951 3230 # places in the country is "the mean solar time for the meridian at
2952 3231 # three degrees, or twelve minutes of time, to the west of the
2953 3232 # meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
2954 3233 #
2955 3234 # The observatory at that time had the meridian 18 degrees 03' 30"
2956 3235 # eastern longitude = 01:12:14 in time. Less 12 minutes gives the
2957 3236 # national standard time as 01:00:14 ahead of GMT....
2958 3237 #
2959 3238 # About the beginning of CET in Sweden. The lawtext ("Svensk
2960 3239 # författningssamling 1899, no 44") states, that "from the beginning
2961 3240 # of 1900... ... the same as the mean solar time for the meridian at
2962 3241 # the distance of one hour of time from the meridian of the English
2963 3242 # observatory at Greenwich, or at 12 minutes 14 seconds to the west
2964 3243 # from the meridian of the Observatory of Stockholm". The law is dated
2965 3244 # 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
2966 3245 # in Sweden is 01:00:00 ahead of GMT.
2967 3246 #
2968 3247 # 1916: The lawtext ("Svensk författningssamling 1916, no 124") states
2969 3248 # that "1916-05-15 is considered to begin one hour earlier". It is
2970 3249 # pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
2971 3250 # Further the law says, that "1916-09-30 is considered to end one hour later".

3014 3293 #
3015 3294 # As I wrote in an earlier message, I suspected the current tzdata values

3027 3306 #
3028 3307 # There was no DST in 1940, I have checked the law collection carefully.
3029 3308 # It is also indicated by the fact that the 1942 entry in the law
3030 3309 # collection points back to 1941 as a reference, but no reference to any
3031 3310 # other years are made.
3032 3311 #
3033 3312 # Newspaper articles I have read in the archives on 6 May 1941 reported
3034 3313 # about the introduction of DST (Sommerzeit in German) during the previous
3035 3314 # night as an absolute novelty, because this was the first time that such
3036 3315 # a thing had happened in Switzerland.
3037 3316 #
3038 3317 # I have also checked 1916, because one book source (Gabriel, Traité de
3039 3318 # l'heure dans le monde) claims that Switzerland had DST in 1916. This is
3040 3319 # false, no official document could be found. Probably Gabriel got misled
3041 3320 # by references to Germany, which introduced DST in 1916 for the first time.

3363 3648 # ...the European time rules are...standardized since 1981, when
3364 3649 # most European countries started DST. Before that year, only
3365 3650 # a few countries (UK, France, Italy) had DST, each according
3366 3651 # to own national rules. In 1981, however, DST started on
3367 3652 # 'Apr firstSun', and not on 'Mar lastSun' as in the following
3368 3653 # years...
3369 3654 # But also since 1981 there are some more national exceptions
3370 3655 # than listed in 'europe': Switzerland, for example, joined DST
3371 3656 # one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
3372 3657 # lastSun' in 1981 - I don't know how they handle now.
3373 3658 #
3374 3659 # Finally, DST ist always from 'Apr 1' to 'Oct 1' in the

3386 3671 # The information from Tom Hofmann is (as far as I know) not entirely correct.
3387 3672 # After a request from chongo at amdahl I tried to retrieve all information
3388 3673 # about DST in Europe. I was able to find all from about 1969.
3389 3674 #
3390 3675 # ...standardization on DST in Europe started in about 1977 with switches on
3391 3676 # first Sunday in April and last Sunday in September...
3392 3677 # In 1981 UK joined Europe insofar that
3393 3678 # the starting day for both shifted to last Sunday in March. And from 1982
3394 3679 # the whole of Europe used DST, with switch dates April 1 and October 1 in
3395 3680 # the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
3396 3681 # dates...
3397 3682 #
3398 3683 # It should also be remembered that time-zones are not constants; e.g.
3399 3684 # Portugal switched in 1976 from MET (or CET) to WET with DST...
3400 3685 # Note also that though there were rules for switch dates not
3401 3686 # all countries abided to these dates, and many individual deviations
3402 3687 # occurred, though not since 1982 I believe. Another note: it is always
3403 3688 # assumed that DST is 1 hour ahead of normal time, this need not be the
3404 3689 # case; at least in the Netherlands there have been times when DST was 2 hours
3405 3690 # in advance of normal time.
