There was a photo # and a sketch map showing some of the sightlines involved. One paragraph # of the text said: # # `An old stone obelisk marking a forgotten terrestrial meridian stands # beside the river at Kew. In the 18th century, before time and longitude # was standardised by the Royal Observatory in Greenwich, scholars observed # this stone and the movement of stars from Kew Observatory nearby. They # made their calculations and set the time for the Horse Guards and Parliament, # but now the stone is obscured by scrubwood and can only be seen by walking # along the towpath within a few yards of it.' # # I have a one inch to one mile map of London and my estimate of the stone's # position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should # be within about +-2". The Ordnance Survey grid reference is TQ172761. # # [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] # From Paul Eggert (1993-11-18): # # Howse writes that Britain was the first country to use standard time. # The railways cared most about the inconsistencies of local mean time, # and it was they who forced a uniform time on the country. # The original idea was credited to Dr. William Hyde Wollaston (1766-1828) # and was popularized by Abraham Follett Osler (1808-1903). # The first railway to adopt London time was the Great Western Railway # in November 1840; other railways followed suit, and by 1847 most # (though not all) railways used London time. On 1847-09-22 the # Railway Clearing House, an industry standards body, recommended that GMT be # adopted at all stations as soon as the General Post Office permitted it. # The transition occurred on 12-01 for the L&NW, the Caledonian, # and presumably other railways; the January 1848 Bradshaw's lists many # railways as using GMT. By 1855 the vast majority of public # clocks in Britain were set to GMT (though some, like the great clock # on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, # one for local time and one for GMT). The last major holdout was the legal # system, which stubbornly stuck to local time for many years, leading # to oddities like polls opening at 08:13 and closing at 16:13. # The legal system finally switched to GMT when the Statutes (Definition # of Time) Act took effect; it received the Royal Assent on 1880-08-02. # # In the tables below, we condense this complicated story into a single # transition date for London, namely 1847-12-01. We don't know as much # about Dublin, so we use 1880-08-02, the legal transition time. # From Paul Eggert (2003-09-27): # Summer Time was first seriously proposed by William Willett (1857-1915), # a London builder and member of the Royal Astronomical Society # who circulated a pamphlet ``The Waste of Daylight'' (1907) # that proposed advancing clocks 20 minutes on each of four Sundays in April, # and retarding them by the same amount on four Sundays in September. # A bill was drafted in 1909 and introduced in Parliament several times, # but it met with ridicule and opposition, especially from farming interests. # Later editions of the pamphlet proposed one-hour summer time, and # it was eventually adopted as a wartime measure in 1916. # See: Summer Time Arrives Early, The Times (2000-05-18). # A monument to Willett was unveiled on 1927-05-21, in an open space in # a 45-acre wood near Chislehurst, Kent that was purchased by popular # subscription and open to the public. On the south face of the monolith, # designed by G. W. Miller, is the the William Willett Memorial Sundial, # which is permanently set to Summer Time. # From Winston Churchill (1934-04-28): # It is one of the paradoxes of history that we should owe the boon of # summer time, which gives every year to the people of this country # between 160 and 170 hours more daylight leisure, to a war which # plunged Europe into darkness for four years, and shook the # foundations of civilization throughout the world. # -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> # "A Silent Toast to William Willett", Pictorial Weekly # </a> # From Paul Eggert (1996-09-03): # The OED Supplement says that the English originally said ``Daylight Saving'' # when they were debating the adoption of DST in 1908; but by 1916 this # term appears only in quotes taken from DST's opponents, whereas the # proponents (who eventually won the argument) are quoted as using ``Summer''. # From Arthur David Olson (1989-01-19): # # A source at the British Information Office in New York avers that it's # known as "British" Summer Time in all parts of the United Kingdom. # Date: 4 Jan 89 08:57:25 GMT (Wed) # From: Jonathan Leffler # [British Summer Time] is fixed annually by Act of Parliament. # If you can predict what Parliament will do, you should be in # politics making a fortune, not computing. # From Chris Carrier (1996-06-14): # I remember reading in various wartime issues of the London Times the # acronym BDST for British Double Summer Time. Look for the published # time of sunrise and sunset in The Times, when BDST was in effect, and # if you find a zone reference it will say, "All times B.D.S.T." # From Joseph S. Myers (1999-09-02): # ... some military cables (WO 219/4100 - this is a copy from the # main SHAEF archives held in the US National Archives, SHAEF/5252/8/516) # agree that the usage is BDST (this appears in a message dated 17 Feb 1945). # From Joseph S. Myers (2000-10-03): # On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir # Alexander Maxwell of the Home Office asking whether there was any # official designation; the reply of the 21st was that there wasn't # but he couldn't think of anything better than the "Double British # Summer Time" that the BBC had been using informally. # http://student.cusu.cam.ac.uk/~jsm28/british-time/bbc-19410418.png # http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png # From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): # [N]o official designation has as far as I know been adopted for the time # which is to be introduced in May.... # I cannot think of anything better than "Double British Summer Time" # which could not be said to run counter to any official description. # From Paul Eggert (2000-10-02): # Howse writes (p 157) `DBST' too, but `BDST' seems to have been common # and follows the more usual convention of putting the location name first, # so we use `BDST'. # Peter Ilieve (1998-04-19) described at length # the history of summer time legislation in the United Kingdom. # Since 1998 Joseph S. Myers has been updating # and extending this list, which can be found in # <a href="http://student.cusu.cam.ac.uk/~jsm28/british-time/"> # History of legal time in Britain # </a> # From Joseph S. Myers (1998-01-06): # # The legal time in the UK outside of summer time is definitely GMT, not UTC; # see Lord Tanlaw's speech # <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn/lds97/text/70611-20.htm#70611-20_head0"> # (Lords Hansard 11 June 1997 columns 964 to 976) # </a>. # From Paul Eggert (2006-03-22): # # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948. # # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger # are incorrect: # * Wales did not switch from GMT to daylight saving time until # 1921 Apr 3, when they began to conform with the rest of Great Britain. # Actually, Wales was identical after 1880. # * Eire had two transitions on 1916 Oct 1. # It actually just had one transition. # * Northern Ireland used single daylight saving time throughout WW II. # Actually, it conformed to Britain. # * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18. # Actually, that date saw the usual switch to summer time. # Standard time was not changed until 1968-10-27 (the clocks didn't change). # # Here is another incorrect claim by Shanks & Pottenger: # * Jersey, Guernsey, and the Isle of Man did not switch from GMT # to daylight saving time until 1921 Apr 3, when they began to # conform with Great Britain. # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise. # # The following claim by Shanks & Pottenger is possible though doubtful; # we'll ignore it for now. # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00. # # # Whitman says Dublin Mean Time was -0:25:21, which is more precise than # Shanks & Pottenger. # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was # to London.

"old style" # might be a reference to the Julian calendar as opposed to Gregorian, or it # might mean something else (???). # # From Paul Eggert (2006-03-22): # The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points. # We go with the Almanak, except for one claim from Shanks & Pottenger, namely # that Reykavik was 21W57 from 1837 to 1908, local mean time before that. # # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Iceland 1917 1918 - Feb 19 23:00 1:00 S Rule Iceland 1917 only - Oct 21 1:00 0 - Rule Iceland 1918 only - Nov 16 1:00 0 - Rule Iceland 1939 only - Apr 29 23:00 1:00 S Rule Iceland 1939 only - Nov 29 2:00 0 - Rule Iceland 1940 only - Feb 25 2:00 1:00 S Rule Iceland 1940 only - Nov 3 2:00 0 - Rule Iceland 1941 only - Mar 2 1:00s 1:00 S Rule Iceland 1941 only - Nov 2 1:00s 0 - Rule Iceland 1942 only - Mar 8 1:00s 1:00 S Rule Iceland 1942 only - Oct 25 1:00s 0 - # 1943-1946 - first Sunday in March until first Sunday in winter Rule Iceland 1943 1946 - Mar Sun>=1 1:00s 1:00 S Rule Iceland 1943 1948 - Oct Sun>=22 1:00s 0 - # 1947-1967 - first Sunday in April until first Sunday in winter Rule Iceland 1947 1967 - Apr Sun>=1 1:00s 1:00 S # 1949 Oct transition delayed by 1 week Rule Iceland 1949 only - Oct 30 1:00s 0 - Rule Iceland 1950 1966 - Oct Sun>=22 1:00s 0 - Rule Iceland 1967 only - Oct 29 1:00s 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Atlantic/Reykjavik -1:27:24 - LMT 1837 -1:27:48 - RMT 1908 # Reykjavik Mean Time? -1:00 Iceland IS%sT 1968 Apr 7 1:00s 0:00 - GMT # Italy # # From Paul Eggert (2001-03-06): # Sicily and Sardinia each had their own time zones from 1866 to 1893, # called Palermo Time (+00:53:28) and Cagliari Time (+00:36:32). # During World War II, German-controlled Italy used German time. # But these events all occurred before the 1970 cutoff, # so record only the time in Rome. # # From Paul Eggert (2006-03-22): # For Italian DST we have three sources: Shanks & Pottenger, Whitman, and # F.

Svalbard was declared # as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan # Mayen by law of 1930-02-27 no 2, section 2. (From # http://www.lovdata.no/all/nl-19250717-011.html and # http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation # for normal/standard time in Norway is from 1894-06-29 no 1 (came # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a # part of this law since 1925/1930. (From # http://www.lovdata.no/all/nl-18940629-001.html ) I have not been # able to find if Jan Mayen used a different time zone (e.g. -0100) # before 1930. Jan Mayen has only been "inhabitated" since 1921 by # Norwegian meteorologists and maybe used the same time as Norway ever # since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since # before 1895, and therefore probably changed the local time somewhere # between 1895 and 1925 (inclusive). # From Paul Eggert (2001-05-01): # # Actually, Jan Mayen was never occupied by Germany during World War II, # so it must have diverged from Oslo time during the war, as Oslo was # keeping Berlin time. # # <http://home.no.net/janmayen/history.htm> says that the meteorologists # burned down their station in 1940 and left the island, but returned in # 1941 with a small Norwegian garrison and continued operations despite # frequent air ttacks from Germans. In 1943 the Americans established a # radiolocating station on the island, called "Atlantic City". Possibly # the UTC offset changed during the war, but I think it unlikely that # Jan Mayen used German daylight-saving rules. # # Svalbard is more complicated, as it was raided in August 1941 by an # Allied party that evacuated the civilian population to England (says # <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ # <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were # expelled on 1942-05-14. However, small parties of Germans did return, # and according to Wilhelm Dege's book "War North of 80" (1954) # <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html> # the German armed forces at the Svalbard weather station code-named # Haudegen did not surrender to the Allies until September 1945. # # All these events predate our cutoff date of 1970.
