16 16 # Gwillim Law writes that a good source
17 17 # for recent time zone data is the International Air Transport
18 18 # Association's Standard Schedules Information Manual (IATA SSIM),
19 19 # published semiannually. Law sent in several helpful summaries
20 20 # of the IATA's data after 1990. Except where otherwise noted,
21 21 # IATA SSIM is the source for entries after 1990.

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.

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.

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 +# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see:

202 205 # From Arthur David Olson (1989-01-19):

204 207 # known as "British" Summer Time in all parts of the United Kingdom.

207 210 # From: Jonathan Leffler
208 211 # [British Summer Time] is fixed annually by Act of Parliament.
209 212 # If you can predict what Parliament will do, you should be in
210 213 # politics making a fortune, not computing.
211 214
212 215 # From Chris Carrier (1996-06-14):
213 216 # I remember reading in various wartime issues of the London Times the
214 217 # acronym BDST for British Double Summer Time. Look for the published
215 218 # time of sunrise and sunset in The Times, when BDST was in effect, and
216 219 # if you find a zone reference it will say, "All times B.D.S.T."
217 220
218 221 # From Joseph S. Myers (1999-09-02):
219 222 # ... some military cables (WO 219/4100 - this is a copy from the
220 223 # main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
221 224 # agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
222 225
223 226 # From Joseph S. Myers (2000-10-03):
224 227 # On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
225 228 # Alexander Maxwell of the Home Office asking whether there was any
226 229 # official designation; the reply of the 21st was that there wasn't
227 230 # but he couldn't think of anything better than the "Double British

233 236 # [N]o official designation has as far as I know been adopted for the time
234 237 # which is to be introduced in May....
235 238 # I cannot think of anything better than "Double British Summer Time"
236 239 # which could not be said to run counter to any official description.
237 240
238 241 # From Paul Eggert (2000-10-02):
239 242 # Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common
240 243 # and follows the more usual convention of putting the location name first,
241 244 # so we use 'BDST'.

248 251
249 252 # From Joseph S. Myers (1998-01-06):
250 253 #
251 254 # The legal time in the UK outside of summer time is definitely GMT, not UTC;
252 255 # see Lord Tanlaw's speech
253 256 # http://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0
254 257 # (Lords Hansard 11 June 1997 columns 964 to 976).
255 258
256 259 # From Paul Eggert (2006-03-22):
257 260 #
258 261 # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
259 262 #
260 263 # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
261 264 # are incorrect:
262 265 # * Wales did not switch from GMT to daylight saving time until
263 266 # 1921 Apr 3, when they began to conform with the rest of Great Britain.
264 267 # Actually, Wales was identical after 1880.
265 268 # * Eire had two transitions on 1916 Oct 1.
266 269 # It actually just had one transition.
267 270 # * Northern Ireland used single daylight saving time throughout WW II.
268 271 # Actually, it conformed to Britain.
269 272 # * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
270 273 # Actually, that date saw the usual switch to summer time.
271 274 # Standard time was not changed until 1968-10-27 (the clocks didn't change).
272 275 #
273 276 # Here is another incorrect claim by Shanks & Pottenger:
274 277 # * Jersey, Guernsey, and the Isle of Man did not switch from GMT
275 278 # to daylight saving time until 1921 Apr 3, when they began to
276 279 # conform with Great Britain.
277 280 # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
278 281 #
279 282 # The following claim by Shanks & Pottenger is possible though doubtful;
280 283 # we'll ignore it for now.
281 284 # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
282 285 #
283 286 #
284 287 # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
285 288 # Shanks & Pottenger.
286 289 # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
287 290 # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
288 291 # to London. For example:

337 340 # My admittedly uninformed guess is that the terminal has two authorities,
338 341 # the French concession operators and the British civil authorities,
339 342 # and that the time depends on who you're talking to.
340 343 # If, say, the British police were called to the station for some reason,
341 344 # I would expect the official police report to use GMT/BST and not CET/CEST.
342 345 # This is a borderline case, but for now let's stick to GMT/BST.

886 889 #
887 890 # This provoked a new law from 1974 to make possible summer time changes

889 892 # http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
890 893 #
891 894 # It seems however that no decree was set forward until 1980. I have
892 895 # not found any decree, but in another related law, the effecting DST
893 896 # changes are stated explicitly to be from 1980-04-06 at 02:00 to
894 897 # 1980-09-28 at 02:00. If this is true, this differs slightly from
895 898 # the EU rule in that DST runs to 02:00, not 03:00. We don't know
896 899 # when Denmark began using the EU rule correctly, but we have only
897 900 # confirmation of the 1980-time, so I presume it was correct in 1981:
898 901 # The law is about the management of the extra hour, concerning
899 902 # working hours reported and effect on obligatory-rest rules (which
900 903 # was suspended on that night):

941 944 # Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
942 945 # and left the EU on 1985-02-01. It therefore should have been using EU
943 946 # rules at least through 1984. Shanks & Pottenger say Scoresbysund and Godthåb
944 947 # used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU

947 950 # From Gwillim Law (2001-06-06), citing
948 951 # <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
949 952 # and with translations corrected by Steffen Thorsen:
950 953 #
951 954 # Greenland has four local times, and the relation to UTC
952 955 # is according to the following time line:
953 956 #
954 957 # The military zone near Thule UTC-4
955 958 # Standard Greenland time UTC-3
956 959 # Scoresbysund UTC-1
957 960 # Danmarkshavn UTC
958 961 #
959 962 # In the military area near Thule and in Danmarkshavn DST will not be
960 963 # introduced.
961 964
962 965 # From Rives McDow (2001-11-01):
963 966 #
964 967 # I correspond regularly with the Dansk Polarcenter, and wrote them at
965 968 # the time to clarify the situation in Thule. Unfortunately, I have
966 969 # not heard back from them regarding my recent letter. [But I have
967 970 # info from earlier correspondence.]
968 971 #
969 972 # According to the center, a very small local time zone around Thule
970 973 # Air Base keeps the time according to UTC-4, implementing daylight
971 974 # savings using North America rules, changing the time at 02:00 local time....
972 975 #
973 976 # The east coast of Greenland north of the community of Scoresbysund
974 977 # uses UTC in the same way as in Iceland, year round, with no dst.
975 978 # There are just a few stations on this coast, including the
976 979 # Danmarkshavn ICAO weather station mentioned in your September 29th
977 980 # email. The other stations are two sledge patrol stations in
978 981 # Mestersvig and Daneborg, the air force base at Station Nord, and the
979 982 # DPC research station at Zackenberg.
980 983 #
981 984 # Scoresbysund and two small villages nearby keep time UTC-1 and use
982 985 # the same daylight savings time period as in West Greenland (Godthåb).
983 986 #
984 987 # The rest of Greenland, including Godthåb (this area, although it
985 988 # includes central Greenland, is known as west Greenland), keeps time
986 989 # UTC-3, with daylight savings methods according to European rules.
987 990 #
988 991 # It is common procedure to use UTC 0 in the wilderness of East and
989 992 # North Greenland, because it is mainly Icelandic aircraft operators
990 993 # maintaining traffic in these areas. However, the official status of
991 994 # this area is that it sticks with Godthåb time. This area might be
992 995 # considered a dual time zone in some respects because of this.
993 996
994 997 # From Rives McDow (2001-11-19):
995 998 # I heard back from someone stationed at Thule; the time change took place
996 999 # there at 2:00 AM.
997 1000
998 1001 # From Paul Eggert (2006-03-22):

1728 1731 # From Paul Eggert (2006-03-22):
1729 1732 # A previous version of this database followed Shanks & Pottenger, who write
1730 1733 # that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1731 1734 # However, this is most likely an error, as Moldova declared independence
1732 1735 # on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1733 1736 # In early 1992 there was large-scale interethnic violence in the area
1734 1737 # and it's possible that some Russophones continued to observe Moscow time.
1735 1738 # But [two people] separately reported via
1736 1739 # Jesper Nørgaard that as of 2001-01-24 Tiraspol was like Chisinau.
1737 1740 # The Tiraspol entry has therefore been removed for now.
1738 1741 #
1739 1742 # From Alexander Krivenyshev (2011-10-17):
1740 1743 # Pridnestrovian Moldavian Republic (PMR, also known as
1741 1744 # "Pridnestrovie") has abolished seasonal clock change (no transition
1742 1745 # to the Winter Time).

1752 1755 # In addition, being situated at +4651+2938 would give Tiraspol

1802 1817 # Amsterdam mean time) onwards, the whole of the Netherlands (including
1803 1818 # the Dutch railways) was required by law to observe Amsterdam mean time
1804 1819 # (19 minutes 32.13 seconds ahead of GMT). This had already been the
1805 1820 # common practice (except for the railways) for many decades but it was
1806 1821 # not until 1909 when the Dutch government finally defined this by law.
1807 1822 # On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
1808 1823 # was generally known as Dutch Time ("Nederlandse Tijd").
1809 1824 #
1810 1825 # (2001-04-08):
1811 1826 # 1892-05-01 was the date when the Dutch railways were by law required to
1812 1827 # observe GMT while the remainder of the Netherlands adhered to the common
1813 1828 # practice of following Amsterdam mean time.
1814 1829 #
1815 1830 # (2001-04-09):
1816 1831 # In 1835 the authorities of the province of North Holland requested the
1817 1832 # municipal authorities of the towns and cities in the province to observe
1818 1833 # Amsterdam mean time but I do not know in how many cases this request was
1819 1834 # actually followed.
1820 1835 #
1821 1836 # From 1852 onwards the Dutch telegraph offices were by law required to
1822 1837 # observe Amsterdam mean time. As the time signals from the observatory of
1823 1838 # Leiden were also distributed by the telegraph system, I assume that most
1824 1839 # places linked up with the telegraph (and railway) system automatically
1825 1840 # adopted Amsterdam mean time.
1826 1841 #
1827 1842 # Although the early Dutch railway companies initially observed a variety
1828 1843 # of times, most of them had adopted Amsterdam mean time by 1858 but it
1829 1844 # was not until 1866 when they were all required by law to observe

1889 1904 # From Steffen Thorsen (2001-05-01):
1890 1905 # Although I could not find it explicitly, it seems that Jan Mayen and
1891 1906 # Svalbard have been using the same time as Norway at least since the
1892 1907 # time they were declared as parts of Norway. Svalbard was declared
1893 1908 # as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
1894 1909 # Mayen by law of 1930-02-27 no 2, section 2. (From
1895 1910 # <http://www.lovdata.no/all/nl-19250717-011.html> and
1896 1911 # <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
1897 1912 # for normal/standard time in Norway is from 1894-06-29 no 1 (came
1898 1913 # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
1899 1914 # part of this law since 1925/1930. (From
1900 1915 # <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
1901 1916 # able to find if Jan Mayen used a different time zone (e.g. -0100)
1902 1917 # before 1930. Jan Mayen has only been "inhabited" since 1921 by
1903 1918 # Norwegian meteorologists and maybe used the same time as Norway ever
1904 1919 # since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
1905 1920 # before 1895, and therefore probably changed the local time somewhere
1906 1921 # between 1895 and 1925 (inclusive).
1907 1922
1908 1923 # From Paul Eggert (2013-09-04):
1909 1924 #
1910 1925 # Actually, Jan Mayen was never occupied by Germany during World War II,
1911 1926 # so it must have diverged from Oslo time during the war, as Oslo was
1912 1927 # keeping Berlin time.
1913 1928 #
1914 1929 # <http://home.no.net/janmayen/history.htm> says that the meteorologists
1915 1930 # burned down their station in 1940 and left the island, but returned in
1916 1931 # 1941 with a small Norwegian garrison and continued operations despite
1917 1932 # frequent air attacks from Germans. In 1943 the Americans established a
1918 1933 # radiolocating station on the island, called "Atlantic City". Possibly
1919 1934 # the UT offset changed during the war, but I think it unlikely that
1920 1935 # Jan Mayen used German daylight-saving rules.
1921 1936 #
1922 1937 # Svalbard is more complicated, as it was raided in August 1941 by an
1923 1938 # Allied party that evacuated the civilian population to England (says

1925 1940 # <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
1926 1941 # expelled on 1942-05-14. However, small parties of Germans did return,
1927 1942 # and according to Wilhelm Dege's book "War North of 80" (1954)

1986 2001 # http://dre.pt/pdf1sdip/1911/05/12500/23132313.pdf
1987 2002 # Lisbon was at -0:36:44.68, but switched to GMT on 1912-01-01 at 00:00.
1988 2003 # Round the old offset to -0:36:45. This agrees with Willett but disagrees
1989 2004 # with Shanks, who says the transition occurred on 1911-05-24 at 00:00 for
1990 2005 # Europe/Lisbon, Atlantic/Azores, and Atlantic/Madeira.
1991 2006 #
1992 2007 # From Rui Pedro Salgueiro (1992-11-12):
1993 2008 # Portugal has recently (September, 27) changed timezone
1994 2009 # (from WET to MET or CET) to harmonize with EEC.
1995 2010 #

1998 2013 # The new Prime Minister was fed up with getting up in the dark in the winter.
1999 2014 #
2000 2015 # From Paul Eggert (1996-11-12):

2002 2017 # at 02:00u, not 01:00u. Assume that these are typos.
2003 2018 # IATA SSIM (1991/1992) reports that the Azores were at -1:00.
2004 2019 # IATA SSIM (1993-02) says +0:00; later issues (through 1996-09) say -1:00.
2005 2020 # Guess that the Azores changed to EU rules in 1992 (since that's when Portugal
2006 2021 # harmonized with the EU), and that they stayed +0:00 that winter.

2932 2947 # From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
2933 2948 #
2934 2949 # The law "Svensk författningssamling 1878, no 14" about standard time in 1879:
2935 2950 # From the beginning of 1879 (that is 01-01 00:00) the time for all
2936 2951 # places in the country is "the mean solar time for the meridian at
2937 2952 # three degrees, or twelve minutes of time, to the west of the
2938 2953 # meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
2939 2954 #
2940 2955 # The observatory at that time had the meridian 18 degrees 03' 30"
2941 2956 # eastern longitude = 01:12:14 in time. Less 12 minutes gives the
2942 2957 # national standard time as 01:00:14 ahead of GMT....
2943 2958 #
2944 2959 # About the beginning of CET in Sweden. The lawtext ("Svensk
2945 2960 # författningssamling 1899, no 44") states, that "from the beginning
2946 2961 # of 1900... ... the same as the mean solar time for the meridian at
2947 2962 # the distance of one hour of time from the meridian of the English
2948 2963 # observatory at Greenwich, or at 12 minutes 14 seconds to the west
2949 2964 # from the meridian of the Observatory of Stockholm". The law is dated
2950 2965 # 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
2951 2966 # in Sweden is 01:00:00 ahead of GMT.
2952 2967 #
2953 2968 # 1916: The lawtext ("Svensk författningssamling 1916, no 124") states
2954 2969 # that "1916-05-15 is considered to begin one hour earlier". It is
2955 2970 # pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
2956 2971 # Further the law says, that "1916-09-30 is considered to end one hour later".

3013 3028 # There was no DST in 1940, I have checked the law collection carefully.

3017 3032 #

3019 3034 # about the introduction of DST (Sommerzeit in German) during the previous

3021 3036 # a thing had happened in Switzerland.
3022 3037 #
3023 3038 # I have also checked 1916, because one book source (Gabriel, Traité de
3024 3039 # l'heure dans le monde) claims that Switzerland had DST in 1916. This is
3025 3040 # false, no official document could be found. Probably Gabriel got misled

3365 3387 # After a request from chongo at amdahl I tried to retrieve all information
3366 3388 # about DST in Europe. I was able to find all from about 1969.

3368 3390 # ...standardization on DST in Europe started in about 1977 with switches on
3369 3391 # first Sunday in April and last Sunday in September...
3370 3392 # In 1981 UK joined Europe insofar that
3371 3393 # the starting day for both shifted to last Sunday in March. And from 1982
3372 3394 # the whole of Europe used DST, with switch dates April 1 and October 1 in
3373 3395 # the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
3374 3396 # dates...
3375 3397 #
3376 3398 # It should also be remembered that time-zones are not constants; e.g.
3377 3399 # Portugal switched in 1976 from MET (or CET) to WET with DST...
3378 3400 # Note also that though there were rules for switch dates not
3379 3401 # all countries abided to these dates, and many individual deviations
3380 3402 # occurred, though not since 1982 I believe. Another note: it is always
3381 3403 # assumed that DST is 1 hour ahead of normal time, this need not be the
3382 3404 # case; at least in the Netherlands there have been times when DST was 2 hours
3383 3405 # in advance of normal time.
