105 104 # Britain (United Kingdom) and Ireland (Eire)
106 105
107 106 # From Peter Ilieve (1994-07-06):
108 107 #
109 108 # On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
110 109 # historical vistas along the Thames in west London. There was a photo
111 110 # and a sketch map showing some of the sightlines involved. One paragraph
112 111 # of the text said:
113 112 #
114 113 # 'An old stone obelisk marking a forgotten terrestrial meridian stands
115 114 # beside the river at Kew. In the 18th century, before time and longitude
116 115 # was standardised by the Royal Observatory in Greenwich, scholars observed
117 116 # this stone and the movement of stars from Kew Observatory nearby. They
118 117 # made their calculations and set the time for the Horse Guards and Parliament,
119 118 # but now the stone is obscured by scrubwood and can only be seen by walking
120 119 # along the towpath within a few yards of it.'
121 120 #
122 121 # I have a one inch to one mile map of London and my estimate of the stone's
123 122 # position is 51 degrees 28' 30" N, 0 degrees 18' 45" W. The longitude should
124 123 # be within about +-2". The Ordnance Survey grid reference is TQ172761.
125 124 #
126 125 # [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
127 126
128 127 # From Paul Eggert (1993-11-18):
129 128 #
130 129 # Howse writes that Britain was the first country to use standard time.
131 130 # The railways cared most about the inconsistencies of local mean time,
132 131 # and it was they who forced a uniform time on the country.
133 132 # The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
134 133 # and was popularized by Abraham Follett Osler (1808-1903).
135 134 # The first railway to adopt London time was the Great Western Railway
136 135 # in November 1840; other railways followed suit, and by 1847 most
137 136 # (though not all) railways used London time. On 1847-09-22 the
138 137 # Railway Clearing House, an industry standards body, recommended that GMT be
139 138 # adopted at all stations as soon as the General Post Office permitted it.
140 139 # The transition occurred on 12-01 for the L&NW, the Caledonian,
141 140 # and presumably other railways; the January 1848 Bradshaw's lists many
142 141 # railways as using GMT. By 1855 the vast majority of public
143 142 # clocks in Britain were set to GMT (though some, like the great clock
144 143 # on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
145 144 # one for local time and one for GMT). The last major holdout was the legal
146 145 # system, which stubbornly stuck to local time for many years, leading
147 146 # to oddities like polls opening at 08:13 and closing at 16:13.
148 147 # The legal system finally switched to GMT when the Statutes (Definition
149 148 # of Time) Act took effect; it received the Royal Assent on 1880-08-02.
150 149 #
151 150 # In the tables below, we condense this complicated story into a single
152 151 # transition date for London, namely 1847-12-01. We don't know as much
153 152 # about Dublin, so we use 1880-08-02, the legal transition time.
154 153
155 154 # From Paul Eggert (2014-07-19):
156 155 # The ancients had no need for daylight saving, as they kept time
157 156 # informally or via hours whose length depended on the time of year.
158 157 # Daylight saving time in its modern sense was invented by the
159 158 # New Zealand entomologist George Vernon Hudson (1867-1946),
160 159 # whose day job as a postal clerk led him to value
161 160 # after-hours daylight in which to pursue his research.
162 161 # In 1895 he presented a paper to the Wellington Philosophical Society
163 162 # that proposed a two-hour daylight-saving shift. See:
164 163 # Hudson GV. On seasonal time-adjustment in countries south of lat. 30 deg.
165 164 # Transactions and Proceedings of the New Zealand Institute. 1895;28:734
166 165 # http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
167 166 # Although some interest was expressed in New Zealand, his proposal
168 167 # did not find its way into law and eventually it was almost forgotten.
169 168 #
170 169 # In England, DST was independently reinvented by William Willett (1857-1915),
171 170 # a London builder and member of the Royal Astronomical Society
172 171 # who circulated a pamphlet "The Waste of Daylight" (1907)
173 172 # that proposed advancing clocks 20 minutes on each of four Sundays in April,
174 173 # and retarding them by the same amount on four Sundays in September.
175 174 # A bill was drafted in 1909 and introduced in Parliament several times,
176 175 # but it met with ridicule and opposition, especially from farming interests.
177 176 # Later editions of the pamphlet proposed one-hour summer time, and
178 177 # it was eventually adopted as a wartime measure in 1916.
179 178 # See: Summer Time Arrives Early, The Times (2000-05-18).
180 179 # A monument to Willett was unveiled on 1927-05-21, in an open space in
181 180 # a 45-acre wood near Chislehurst, Kent that was purchased by popular
182 181 # subscription and open to the public. On the south face of the monolith,
183 182 # designed by G. W. Miller, is the William Willett Memorial Sundial,
184 183 # which is permanently set to Summer Time.
185 184
186 185 # From Winston Churchill (1934-04-28):
187 186 # It is one of the paradoxes of history that we should owe the boon of
188 187 # summer time, which gives every year to the people of this country
189 188 # between 160 and 170 hours more daylight leisure, to a war which
190 189 # plunged Europe into darkness for four years, and shook the
191 190 # foundations of civilization throughout the world.

195 194
196 195 # From Paul Eggert (2015-08-08):
197 196 # The OED Supplement says that the English originally said "Daylight Saving"
198 197 # when they were debating the adoption of DST in 1908; but by 1916 this
199 198 # term appears only in quotes taken from DST's opponents, whereas the
200 199 # proponents (who eventually won the argument) are quoted as using "Summer".
201 200 # The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see:
202 201 # Viscount Samuel. Leisure in a Democracy. Cambridge University Press
203 202 # ISBN 978-1-107-49471-8 (1949, reissued 2015), p 8.
204 203
205 204 # From Arthur David Olson (1989-01-19):
206 205 # A source at the British Information Office in New York avers that it's
207 206 # known as "British" Summer Time in all parts of the United Kingdom.
208 207
209 208 # Date: 4 Jan 89 08:57:25 GMT (Wed)
210 209 # From: Jonathan Leffler
211 210 # [British Summer Time] is fixed annually by Act of Parliament.
212 211 # If you can predict what Parliament will do, you should be in
213 212 # politics making a fortune, not computing.
214 213
215 214 # From Chris Carrier (1996-06-14):
216 215 # I remember reading in various wartime issues of the London Times the
217 216 # acronym BDST for British Double Summer Time. Look for the published
218 217 # time of sunrise and sunset in The Times, when BDST was in effect, and
219 218 # if you find a zone reference it will say, "All times B.D.S.T."
220 219
221 220 # From Joseph S. Myers (1999-09-02):
222 221 # ... some military cables (WO 219/4100 - this is a copy from the
223 222 # main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
224 223 # agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
225 224
226 225 # From Joseph S. Myers (2000-10-03):
227 226 # On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
228 227 # Alexander Maxwell of the Home Office asking whether there was any
229 228 # official designation; the reply of the 21st was that there wasn't
230 229 # but he couldn't think of anything better than the "Double British
231 230 # Summer Time" that the BBC had been using informally.

234 233
235 234 # From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
236 235 # [N]o official designation has as far as I know been adopted for the time
237 236 # which is to be introduced in May....
238 237 # I cannot think of anything better than "Double British Summer Time"
239 238 # which could not be said to run counter to any official description.
240 239
241 240 # From Paul Eggert (2000-10-02):
242 241 # Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common
243 242 # and follows the more usual convention of putting the location name first,
244 243 # so we use 'BDST'.
245 244
246 245 # Peter Ilieve (1998-04-19) described at length
247 246 # the history of summer time legislation in the United Kingdom.

250 249 # http://www.polyomino.org.uk/british-time/
251 250
252 251 # From Joseph S. Myers (1998-01-06):
253 252 #
254 253 # The legal time in the UK outside of summer time is definitely GMT, not UTC;
255 254 # see Lord Tanlaw's speech
256 255 # http://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0

258 257
259 258 # From Paul Eggert (2006-03-22):
260 259 #
261 260 # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
262 261 #
263 262 # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
264 263 # are incorrect:
265 264 # * Wales did not switch from GMT to daylight saving time until
266 265 # 1921 Apr 3, when they began to conform with the rest of Great Britain.
267 266 # Actually, Wales was identical after 1880.
268 267 # * Eire had two transitions on 1916 Oct 1.
269 268 # It actually just had one transition.
270 269 # * Northern Ireland used single daylight saving time throughout WW II.
271 270 # Actually, it conformed to Britain.
272 271 # * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
273 272 # Actually, that date saw the usual switch to summer time.
274 273 # Standard time was not changed until 1968-10-27 (the clocks didn't change).
275 274 #
276 275 # Here is another incorrect claim by Shanks & Pottenger:
277 276 # * Jersey, Guernsey, and the Isle of Man did not switch from GMT
278 277 # to daylight saving time until 1921 Apr 3, when they began to
279 278 # conform with Great Britain.
280 279 # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
281 280 #
282 281 # The following claim by Shanks & Pottenger is possible though doubtful;
283 282 # we'll ignore it for now.
284 283 # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
285 284 #
286 285 #
287 286 # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
288 287 # Shanks & Pottenger.
289 288 # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
290 289 # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
291 290 # to London. For example:

335 334 # reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
336 335 # (CT), equivalent to French civil time.
337 336 # Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
338 337 # trains between Dollands Moor (the freight facility next door)
339 338 # and Frethun run in CT.
340 339 # My admittedly uninformed guess is that the terminal has two authorities,
341 340 # the French concession operators and the British civil authorities,
342 341 # and that the time depends on who you're talking to.
343 342 # If, say, the British police were called to the station for some reason,
344 343 # I would expect the official police report to use GMT/BST and not CET/CEST.
345 344 # This is a borderline case, but for now let's stick to GMT/BST.

347 346 # From an anonymous contributor (1996-06-02):
348 347 # The law governing time in Ireland is under Statutory Instrument SI 395/94,
349 348 # which gives force to European Union 7th Council Directive No. 94/21/EC.
350 349 # Under this directive, the Minister for Justice in Ireland makes appropriate
351 350 # regulations. I spoke this morning with the Secretary of the Department of
352 351 # Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
353 352 # "Irish Summer Time", abbreviated to "IST".

995 1017 #
996 1018 # The east coast of Greenland north of the community of Scoresbysund
997 1019 # uses UTC in the same way as in Iceland, year round, with no dst.
998 1020 # There are just a few stations on this coast, including the
999 1021 # Danmarkshavn ICAO weather station mentioned in your September 29th

1001 1023 # Mestersvig and Daneborg, the air force base at Station Nord, and the
1002 1024 # DPC research station at Zackenberg.
1003 1025 #
1004 1026 # Scoresbysund and two small villages nearby keep time UTC-1 and use
1005 1027 # the same daylight savings time period as in West Greenland (Godthåb).
1006 1028 #
1007 1029 # The rest of Greenland, including Godthåb (this area, although it
1008 1030 # includes central Greenland, is known as west Greenland), keeps time
1009 1031 # UTC-3, with daylight savings methods according to European rules.
1010 1032 #
1011 1033 # It is common procedure to use UTC 0 in the wilderness of East and
1012 1034 # North Greenland, because it is mainly Icelandic aircraft operators
1013 1035 # maintaining traffic in these areas. However, the official status of
1014 1036 # this area is that it sticks with Godthåb time. This area might be

1422 1444 #
1423 1445 # From January 1st, 1908 the whole of Iceland was standardised at 1 hour

1945 1967 # From Steffen Thorsen (2001-05-01):
1946 1968 # Although I could not find it explicitly, it seems that Jan Mayen and
1947 1969 # Svalbard have been using the same time as Norway at least since the
1948 1970 # time they were declared as parts of Norway. Svalbard was declared
1949 1971 # as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
1950 1972 # Mayen by law of 1930-02-27 no 2, section 2. (From
1951 1973 # <http://www.lovdata.no/all/nl-19250717-011.html> and
1952 1974 # <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
1953 1975 # for normal/standard time in Norway is from 1894-06-29 no 1 (came
1954 1976 # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
1955 1977 # part of this law since 1925/1930. (From
1956 1978 # <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
1957 1979 # able to find if Jan Mayen used a different time zone (e.g. -0100)
1958 1980 # before 1930. Jan Mayen has only been "inhabited" since 1921 by
1959 1981 # Norwegian meteorologists and maybe used the same time as Norway ever
1960 1982 # since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
1961 1983 # before 1895, and therefore probably changed the local time somewhere
1962 1984 # between 1895 and 1925 (inclusive).
1963 1985
1964 1986 # From Paul Eggert (2013-09-04):
1965 1987 #
1966 1988 # Actually, Jan Mayen was never occupied by Germany during World War II,
1967 1989 # so it must have diverged from Oslo time during the war, as Oslo was
1968 1990 # keeping Berlin time.
1969 1991 #
1970 1992 # <http://home.no.net/janmayen/history.htm> says that the meteorologists
1971 1993 # burned down their station in 1940 and left the island, but returned in
1972 1994 # 1941 with a small Norwegian garrison and continued operations despite
1973 1995 # frequent air attacks from Germans. In 1943 the Americans established a
1974 1996 # radiolocating station on the island, called "Atlantic City". Possibly
1975 1997 # the UT offset changed during the war, but I think it unlikely that
1976 1998 # Jan Mayen used German daylight-saving rules.
1977 1999 #
1978 2000 # Svalbard is more complicated, as it was raided in August 1941 by an

2254 -# Except for Moscow after 1919-07-01, I invented the time zone abbreviations.
2255 2276 # Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,

2261 2282 # But now it is some months since Novosibirsk is 3 hours ahead of Moscow!
2262 2283 # I do not know why they have decided to make this change;
2263 2284 # as far as I remember it was done exactly during winter->summer switching
2264 2285 # so we (Novosibirsk) simply did not switch.

2266 2287 # From Andrey A. Chernov (1996-10-04):
2267 2288 # 'MSK' and 'MSD' were born and used initially on Moscow computers with
2268 2289 # UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
2269 2290 # The next step was the UUCP network, the Relcom predecessor
2270 2291 # (used mainly for mail), and MSK/MSD was actively used there.

2282 2303 # enforcing curfew at the wrong time.
2283 2304 #
2284 2305 # From Gwillim Law (2001-06-05):
2285 2306 # There's considerable evidence that Sakhalin Island used to be in
2286 2307 # UTC+11, and has changed to UTC+10, in this decade. I start with the
2287 2308 # SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
2288 2309 # until February 1997, and then in RU9 with Khabarovsk and Vladivostok
2289 2310 # since September 1997.... Although the Kuril Islands are
2290 2311 # administratively part of Sakhalin oblast', they appear to have
2291 2312 # remained on UTC+11 along with Magadan.

3226 3275 # From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
3227 3276 #
3228 3277 # The law "Svensk författningssamling 1878, no 14" about standard time in 1879:
3229 3278 # From the beginning of 1879 (that is 01-01 00:00) the time for all
3230 3279 # places in the country is "the mean solar time for the meridian at
3231 3280 # three degrees, or twelve minutes of time, to the west of the
3232 3281 # meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
3233 3282 #
3234 3283 # The observatory at that time had the meridian 18 degrees 03' 30"
3235 3284 # eastern longitude = 01:12:14 in time. Less 12 minutes gives the
3236 3285 # national standard time as 01:00:14 ahead of GMT....
3237 3286 #
3238 3287 # About the beginning of CET in Sweden. The lawtext ("Svensk
3239 3288 # författningssamling 1899, no 44") states, that "from the beginning
3240 3289 # of 1900... ... the same as the mean solar time for the meridian at
3241 3290 # the distance of one hour of time from the meridian of the English
3242 3291 # observatory at Greenwich, or at 12 minutes 14 seconds to the west
3243 3292 # from the meridian of the Observatory of Stockholm". The law is dated
3244 3293 # 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
3245 3294 # in Sweden is 01:00:00 ahead of GMT.
3246 3295 #
3247 3296 # 1916: The lawtext ("Svensk författningssamling 1916, no 124") states
3248 3297 # that "1916-05-15 is considered to begin one hour earlier". It is
3249 3298 # pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
3250 3299 # Further the law says, that "1916-09-30 is considered to end one hour later".

3292 3341 # I have researched the DST usage in Switzerland during the 1940ies.
3293 3342 #
3294 3343 # As I wrote in an earlier message, I suspected the current tzdata values
3295 3344 # to be wrong. This is now verified.
3296 3345 #

3305 3354 # DST ended on Monday, 5 Oct 1942 at 02:00 am
3306 3355 #
3307 3356 # There was no DST in 1940, I have checked the law collection carefully.
3308 3357 # It is also indicated by the fact that the 1942 entry in the law
3309 3358 # collection points back to 1941 as a reference, but no reference to any
3310 3359 # other years are made.
3311 3360 #
3312 3361 # Newspaper articles I have read in the archives on 6 May 1941 reported
3313 3362 # about the introduction of DST (Sommerzeit in German) during the previous
3314 3363 # night as an absolute novelty, because this was the first time that such
3315 3364 # a thing had happened in Switzerland.
3316 3365 #
3317 3366 # I have also checked 1916, because one book source (Gabriel, Traité de
3318 3367 # l'heure dans le monde) claims that Switzerland had DST in 1916. This is
3319 3368 # false, no official document could be found. Probably Gabriel got misled
3320 3369 # by references to Germany, which introduced DST in 1916 for the first time.
3321 3370 #
3322 3371 # The tzdata rules for Switzerland must be changed to:
3323 3372 # Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S

3329 3378 # most users of tzdata: The [Europe/Zurich zone] ...
3330 3379 # describes all of Switzerland correctly, with the exception of
3331 3380 # the Canton de Genève (Geneva, Genf). Between 1848 and 1894 Geneva did not
3332 3381 # follow Bern Mean Time but kept its own local mean time.
3333 3382 # To represent this, an extra zone would be needed.

3363 3412 # (Bundesblatt 1853, Bd. II, S. 859). On p 72 Messerli writes that in
3364 3413 # practice since July 1853 Bernese time was used in "all postal and telegraph
3365 3414 # offices in Switzerland from Geneva to St. Gallen and Basel to Chiasso"
3366 3415 # (Google translation). For now, model this transition as occurring on

3648 3708 # ...the European time rules are...standardized since 1981, when
3649 3709 # most European countries started DST. Before that year, only
3650 3710 # a few countries (UK, France, Italy) had DST, each according
3651 3711 # to own national rules. In 1981, however, DST started on
3652 3712 # 'Apr firstSun', and not on 'Mar lastSun' as in the following
3653 3713 # years...
3654 3714 # But also since 1981 there are some more national exceptions
3655 3715 # than listed in 'europe': Switzerland, for example, joined DST
3656 3716 # one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
3657 3717 # lastSun' in 1981 - I don't know how they handle now.
3658 3718 #
3659 3719 # Finally, DST ist always from 'Apr 1' to 'Oct 1' in the

3671 3731 # The information from Tom Hofmann is (as far as I know) not entirely correct.
3672 3732 # After a request from chongo at amdahl I tried to retrieve all information
3673 3733 # about DST in Europe. I was able to find all from about 1969.
3674 3734 #
3675 3735 # ...standardization on DST in Europe started in about 1977 with switches on
3676 3736 # first Sunday in April and last Sunday in September...
3677 3737 # In 1981 UK joined Europe insofar that
3678 3738 # the starting day for both shifted to last Sunday in March. And from 1982
3679 3739 # the whole of Europe used DST, with switch dates April 1 and October 1 in
3680 3740 # the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
3681 3741 # dates...
3682 3742 #
3683 3743 # It should also be remembered that time-zones are not constants; e.g.
3684 3744 # Portugal switched in 1976 from MET (or CET) to WET with DST...
3685 3745 # Note also that though there were rules for switch dates not
3686 3746 # all countries abided to these dates, and many individual deviations
3687 3747 # occurred, though not since 1982 I believe. Another note: it is always
3688 3748 # assumed that DST is 1 hour ahead of normal time, this need not be the
3689 3749 # case; at least in the Netherlands there have been times when DST was 2 hours
3690 3750 # in advance of normal time.
