 113  124  # From Paul Eggert (1993-11-18):
 114  125  #
 115  126  # Howse writes that Britain was the first country to use standard time.
 116  127  # The railways cared most about the inconsistencies of local mean time,
 117  128  # and it was they who forced a uniform time on the country.
 118  129  # The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
 119  130  # and was popularized by Abraham Follett Osler (1808-1903).
 120  131  # The first railway to adopt London time was the Great Western Railway
 121  132  # in November 1840; other railways followed suit, and by 1847 most
 122  133  # (though not all) railways used London time.  On 1847-09-22 the
 123  134  # Railway Clearing House, an industry standards body, recommended that GMT be
 124  135  # adopted at all stations as soon as the General Post Office permitted it.
 125  136  # The transition occurred on 12-01 for the L&NW, the Caledonian,
 126  137  # and presumably other railways; the January 1848 Bradshaw's lists many
 127  138  # railways as using GMT.  By 1855 the vast majority of public
 128  139  # clocks in Britain were set to GMT (though some, like the great clock
 129  140  # on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,

 130  141  # one for local time and one for GMT).  The last major holdout was the legal
 131  142  # system, which stubbornly stuck to local time for many years, leading
 132  143  # to oddities like polls opening at 08:13 and closing at 16:13.
 133  144  # The legal system finally switched to GMT when the Statutes (Definition
 134  145  # of Time) Act took effect; it received the Royal Assent on 1880-08-02.
 135  146  #
 136  147  # In the tables below, we condense this complicated story into a single
 137  148  # transition date for London, namely 1847-12-01.  We don't know as much
 138  149  # about Dublin, so we use 1880-08-02, the legal transition time.

 140      -# From Paul Eggert (2003-09-27):
 141      -# Summer Time was first seriously proposed by William Willett (1857-1915),
      151 +# From Paul Eggert (2014-07-19):
      152 +# The ancients had no need for daylight saving, as they kept time
      153 +# informally or via hours whose length depended on the time of year.
      154 +# Daylight saving time in its modern sense was invented by the
      155 +# New Zealand entomologist George Vernon Hudson (1867-1946),
      156 +# whose day job as a postal clerk led him to value
      157 +# after-hours daylight in which to pursue his research.
      158 +# In 1895 he presented a paper to the Wellington Philosophical Society
      159 +# that proposed a two-hour daylight-saving shift.  See:
      160 +# Hudson GV. On seasonal time-adjustment in countries south of lat. 30 deg.
      161 +# Transactions and Proceedings of the New Zealand Institute. 1895;28:734
      162 +# http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
      163 +# Although some interest was expressed in New Zealand, his proposal
      164 +# did not find its way into law and eventually it was almost forgotten.
      165 +#
      166 +# In England, DST was independently reinvented by William Willett (1857-1915),
 142  167  # a London builder and member of the Royal Astronomical Society
 143  168  # who circulated a pamphlet "The Waste of Daylight" (1907)
 144  169  # that proposed advancing clocks 20 minutes on each of four Sundays in April,
 145  170  # and retarding them by the same amount on four Sundays in September.
 146  171  # A bill was drafted in 1909 and introduced in Parliament several times,
 147  172  # but it met with ridicule and opposition, especially from farming interests.
 148  173  # Later editions of the pamphlet proposed one-hour summer time, and
 149  174  # it was eventually adopted as a wartime measure in 1916.
 150  175  # See: Summer Time Arrives Early, The Times (2000-05-18).
 151  176  # A monument to Willett was unveiled on 1927-05-21, in an open space in
 152  177  # a 45-acre wood near Chislehurst, Kent that was purchased by popular
 153  178  # subscription and open to the public.  On the south face of the monolith,

 157  182  # From Winston Churchill (1934-04-28):
 158  183  # It is one of the paradoxes of history that we should owe the boon of
 159  184  # summer time, which gives every year to the people of this country
 160  185  # between 160 and 170 hours more daylight leisure, to a war which
 161  186  # plunged Europe into darkness for four years, and shook the
 162  187  # foundations of civilization throughout the world.

 237  252  # From Paul Eggert (2006-03-22):
 238  253  #
 239  254  # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
 240  255  #
 241  256  # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
 242  257  # are incorrect:
 243  258  #     * Wales did not switch from GMT to daylight saving time until
 244  259  #       1921 Apr 3, when they began to conform with the rest of Great Britain.
 245  260  # Actually, Wales was identical after 1880.
 246  261  #     * Eire had two transitions on 1916 Oct 1.
 247  262  # It actually just had one transition.
 248  263  #     * Northern Ireland used single daylight saving time throughout WW II.
 249  264  # Actually, it conformed to Britain.
 250  265  #     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
 251  266  # Actually, that date saw the usual switch to summer time.
 252  267  # Standard time was not changed until 1968-10-27 (the clocks didn't change).
 253  268  #
 254  269  # Here is another incorrect claim by Shanks & Pottenger:
 255  270  #     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
 256  271  #       to daylight saving time until 1921 Apr 3, when they began to
 257  272  #       conform with Great Britain.
 258  273  # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
 259  274  #
 260  275  # The following claim by Shanks & Pottenger is possible though doubtful;
 261  276  # we'll ignore it for now.
 262  277  #     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.

 265  280  # Whitman says Dublin Mean Time was -0:25:21, which is more precise than
 266  281  # Shanks & Pottenger.
 267  282  # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
 268  283  # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
 269  284  # to London.  For example:

1347 1362  # From Adam David (1993-11-06):
1348 1363  # The name of the timezone in Iceland for system / mail / news purposes is GMT.
1349 1364  #
1350 1365  # (1993-12-05):
1351 1366  # This material is paraphrased from the 1988 edition of the University of
1352 1367  # Iceland Almanak.
1353 1368  #
1354 1369  # From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1355 1370  # behind GMT. Previously, local mean solar time was used in different parts
1356 1371  # of Iceland, the almanak had been based on Reykjavik mean solar time which
1357 1372  # was 1 hour and 28 minutes behind GMT.
1358 1373  #
1359 1374  # "first day of winter" referred to [below] means the first day of the 26 weeks
1360 1375  # of winter, according to the old icelandic calendar that dates back to the
1361 1376  # time the norsemen first settled Iceland.  The first day of winter is always
1362 1377  # Saturday, but is not dependent on the Julian or Gregorian calendars.
1363 1378  #
1364 1379  # (1993-12-10):
1365 1380  # I have a reference from the Oxford Icelandic-English dictionary for the
1366 1381  # beginning of winter, which ties it to the ecclesiastical calendar (and thus
1367 1382  # to the julian/gregorian calendar) over the period in question.
1368 1383  #       the winter begins on the Saturday next before St. Luke's day
1369 1384  #       (old style), or on St. Luke's day, if a Saturday.
1370 1385  # St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1371 1386  # might be a reference to the Julian calendar as opposed to Gregorian, or it
1372 1387  # might mean something else (???).
1373 1388  #
1374 1389  # From Paul Eggert (2006-03-22):
1375 1390  # The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points.
1376 1391  # We go with the Almanak, except for one claim from Shanks & Pottenger, namely
1377 1392  # that Reykavik was 21W57 from 1837 to 1908, local mean time before that.

1692 1711  # A previous version of this database followed Shanks & Pottenger, who write
1693 1712  # that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
1694 1713  # However, this is most likely an error, as Moldova declared independence
1695 1714  # on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
1696 1715  # In early 1992 there was large-scale interethnic violence in the area
1697 1716  # and it's possible that some Russophones continued to observe Moscow time.
1698 1717  # But [two people] separately reported via
1699      -# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.

1880 1892  # Actually, Jan Mayen was never occupied by Germany during World War II,

1887      -# frequent air ttacks from Germans.  In 1943 the Americans established a
     1899 +# frequent air attacks from Germans.  In 1943 the Americans established a
1888 1900  # radiolocating station on the island, called "Atlantic City".  Possibly
1889 1901  # the UT offset changed during the war, but I think it unlikely that
1890 1902  # Jan Mayen used German daylight-saving rules.

1892 1904  # Svalbard is more complicated, as it was raided in August 1941 by an

2992 3346  # The information from Tom Hofmann is (as far as I know) not entirely correct.
2993 3347  # After a request from chongo at amdahl I tried to retrieve all information
2994 3348  # about DST in Europe.  I was able to find all from about 1969.
2995 3349  #
2996 3350  # ...standardization on DST in Europe started in about 1977 with switches on
2997 3351  # first Sunday in April and last Sunday in September...
2998 3352  # In 1981 UK joined Europe insofar that
2999 3353  # the starting day for both shifted to last Sunday in March.  And from 1982
3000 3354  # the whole of Europe used DST, with switch dates April 1 and October 1 in
3001 3355  # the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
3002 3356  # dates...
3003 3357  #
3004 3358  # It should also be remembered that time-zones are not constants; e.g.
3005 3359  # Portugal switched in 1976 from MET (or CET) to WET with DST...
3006 3360  # Note also that though there were rules for switch dates not
3007 3361  # all countries abided to these dates, and many individual deviations
3008 3362  # occurred, though not since 1982 I believe.  Another note: it is always
3009 3363  # assumed that DST is 1 hour ahead of normal time, this need not be the
3010 3364  # case; at least in the Netherlands there have been times when DST was 2 hours
3011 3365  # in advance of normal time.
