There was a photo 114 # and a sketch map showing some of the sightlines involved. One paragraph 115 # of the text said: 116 # 117 # `An old stone obelisk marking a forgotten terrestrial meridian stands 118 # beside the river at Kew. In the 18th century, before time and longitude 119 # was standardised by the Royal Observatory in Greenwich, scholars observed 120 # this stone and the movement of stars from Kew Observatory nearby. They 121 # made their calculations and set the time for the Horse Guards and Parliament, 122 # but now the stone is obscured by scrubwood and can only be seen by walking 123 # along the towpath within a few yards of it.' 124 # 125 # I have a one inch to one mile map of London and my estimate of the stone's 126 # position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should 127 # be within about +-2". The Ordnance Survey grid reference is TQ172761. 128 # 129 # [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] 130 131 # From Paul Eggert (1993-11-18): 132 # 133 # Howse writes that Britain was the first country to use standard time. 134 # The railways cared most about the inconsistencies of local mean time, 135 # and it was they who forced a uniform time on the country. 136 # The original idea was credited to Dr. William Hyde Wollaston (1766-1828) 137 # and was popularized by Abraham Follett Osler (1808-1903). 138 # The first railway to adopt London time was the Great Western Railway 139 # in November 1840; other railways followed suit, and by 1847 most 140 # (though not all) railways used London time. On 1847-09-22 the 141 # Railway Clearing House, an industry standards body, recommended that GMT be 142 # adopted at all stations as soon as the General Post Office permitted it. 143 # The transition occurred on 12-01 for the L&NW, the Caledonian, 144 # and presumably other railways; the January 1848 Bradshaw's lists many 145 # railways as using GMT. By 1855 the vast majority of public 146 # clocks in Britain were set to GMT (though some, like the great clock 147 # on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, 148 # one for local time and one for GMT). The last major holdout was the legal 149 # system, which stubbornly stuck to local time for many years, leading 150 # to oddities like polls opening at 08:13 and closing at 16:13. 151 # The legal system finally switched to GMT when the Statutes (Definition 152 # of Time) Act took effect; it received the Royal Assent on 1880-08-02. 153 # 154 # In the tables below, we condense this complicated story into a single 155 # transition date for London, namely 1847-12-01. We don't know as much 156 # about Dublin, so we use 1880-08-02, the legal transition time. 157 158 # From Paul Eggert (2003-09-27): 159 # Summer Time was first seriously proposed by William Willett (1857-1915), 160 # a London builder and member of the Royal Astronomical Society 161 # who circulated a pamphlet ``The Waste of Daylight'' (1907) 162 # that proposed advancing clocks 20 minutes on each of four Sundays in April, 163 # and retarding them by the same amount on four Sundays in September. 164 # A bill was drafted in 1909 and introduced in Parliament several times, 165 # but it met with ridicule and opposition, especially from farming interests. 166 # Later editions of the pamphlet proposed one-hour summer time, and 167 # it was eventually adopted as a wartime measure in 1916. 168 # See: Summer Time Arrives Early, The Times (2000-05-18). 169 # A monument to Willett was unveiled on 1927-05-21, in an open space in 170 # a 45-acre wood near Chislehurst, Kent that was purchased by popular 171 # subscription and open to the public. On the south face of the monolith, 172 # designed by G. W. Miller, is the...William Willett Memorial Sundial, 173 # which is permanently set to Summer Time. 174 175 # From Winston Churchill (1934-04-28): 176 # It is one of the paradoxes of history that we should owe the boon of 177 # summer time, which gives every year to the people of this country 178 # between 160 and 170 hours more daylight leisure, to a war which 179 # plunged Europe into darkness for four years, and shook the 180 # foundations of civilization throughout the world. 181 # -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> 182 # "A Silent Toast to William Willett", Pictorial Weekly 183 # </a> 184 185 # From Paul Eggert (1996-09-03): 186 # The OED Supplement says that the English originally said ``Daylight Saving'' 187 # when they were debating the adoption of DST in 1908; but by 1916 this 188 # term appears only in quotes taken from DST's opponents, whereas the 189 # proponents (who eventually won the argument) are quoted as using ``Summer''. 190 191 # From Arthur David Olson (1989-01-19): 192 # 193 # A source at the British Information Office in New York avers that it's 194 # known as "British" Summer Time in all parts of the United Kingdom. 195 196 # Date: 4 Jan 89 08:57:25 GMT (Wed) 197 # From: Jonathan Leffler 198 # [British Summer Time] is fixed annually by Act of Parliament. 199 # If you can predict what Parliament will do, you should be in 200 # politics making a fortune, not computing. 201 202 # From Chris Carrier (1996-06-14): 203 # I remember reading in various wartime issues of the London Times the 204 # acronym BDST for British Double Summer Time.

As the time signals from the observatory of 1779 # Leiden were also distributed by the telegraph system, I assume that most 1780 # places linked up with the telegraph (and railway) system automatically 1781 # adopted Amsterdam mean time. 1782 # 1783 # Although the early Dutch railway companies initially observed a variety 1784 # of times, most of them had adopted Amsterdam mean time by 1858 but it 1785 # was not until 1866 when they were all required by law to observe 1786 # Amsterdam mean time. 1787 1788 # The data before 1945 are taken from 1789 # <http://www.phys.uu.nl/~vgent/wettijd/wettijd.htm>. 1790 1791 # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 1792 Rule Neth 1916 only - May 1 0:00 1:00 NST # Netherlands Summer Time 1793 Rule Neth 1916 only - Oct 1 0:00 0 AMT # Amsterdam Mean Time 1794 Rule Neth 1917 only - Apr 16 2:00s 1:00 NST 1795 Rule Neth 1917 only - Sep 17 2:00s 0 AMT 1796 Rule Neth 1918 1921 - Apr Mon>=1 2:00s 1:00 NST 1797 Rule Neth 1918 1921 - Sep lastMon 2:00s 0 AMT 1798 Rule Neth 1922 only - Mar lastSun 2:00s 1:00 NST 1799 Rule Neth 1922 1936 - Oct Sun>=2 2:00s 0 AMT 1800 Rule Neth 1923 only - Jun Fri>=1 2:00s 1:00 NST 1801 Rule Neth 1924 only - Mar lastSun 2:00s 1:00 NST 1802 Rule Neth 1925 only - Jun Fri>=1 2:00s 1:00 NST 1803 # From 1926 through 1939 DST began 05-15, except that it was delayed by a week 1804 # in years when 05-15 fell in the Pentecost weekend. 1805 Rule Neth 1926 1931 - May 15 2:00s 1:00 NST 1806 Rule Neth 1932 only - May 22 2:00s 1:00 NST 1807 Rule Neth 1933 1936 - May 15 2:00s 1:00 NST 1808 Rule Neth 1937 only - May 22 2:00s 1:00 NST 1809 Rule Neth 1937 only - Jul 1 0:00 1:00 S 1810 Rule Neth 1937 1939 - Oct Sun>=2 2:00s 0 - 1811 Rule Neth 1938 1939 - May 15 2:00s 1:00 S 1812 Rule Neth 1945 only - Apr 2 2:00s 1:00 S 1813 Rule Neth 1945 only - Sep 16 2:00s 0 - 1814 # 1815 # Amsterdam Mean Time was +00:19:32.13 exactly, but the .13 is omitted 1816 # below because the current format requires GMTOFF to be an integer. 1817 # Zone NAME GMTOFF RULES FORMAT [UNTIL] 1818 Zone Europe/Amsterdam 0:19:32 - LMT 1835 1819 0:19:32 Neth %s 1937 Jul 1 1820 0:20 Neth NE%sT 1940 May 16 0:00 # Dutch Time 1821 1:00 C-Eur CE%sT 1945 Apr 2 2:00 1822 1:00 Neth CE%sT 1977 1823 1:00 EU CE%sT 1824 1825 # Norway 1826 # http://met.no/met/met_lex/q_u/sommertid.html (2004-01) agrees with Shanks & 1827 # Pottenger. 1828 # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 1829 Rule Norway 1916 only - May 22 1:00 1:00 S 1830 Rule Norway 1916 only - Sep 30 0:00 0 - 1831 Rule Norway 1945 only - Apr 2 2:00s 1:00 S 1832 Rule Norway 1945 only - Oct 1 2:00s 0 - 1833 Rule Norway 1959 1964 - Mar Sun>=15 2:00s 1:00 S 1834 Rule Norway 1959 1965 - Sep Sun>=15 2:00s 0 - 1835 Rule Norway 1965 only - Apr 25 2:00s 1:00 S 1836 # Zone NAME GMTOFF RULES FORMAT [UNTIL] 1837 Zone Europe/Oslo 0:43:00 - LMT 1895 Jan 1 1838 1:00 Norway CE%sT 1940 Aug 10 23:00 1839 1:00 C-Eur CE%sT 1945 Apr 2 2:00 1840 1:00 Norway CE%sT 1980 1841 1:00 EU CE%sT 1842 1843 # Svalbard & Jan Mayen 1844 1845 # From Steffen Thorsen (2001-05-01): 1846 # Although I could not find it explicitly, it seems that Jan Mayen and 1847 # Svalbard have been using the same time as Norway at least since the 1848 # time they were declared as parts of Norway.

The law/regulation 1853 # for normal/standard time in Norway is from 1894-06-29 no 1 (came 1854 # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a 1855 # part of this law since 1925/1930.

Jan Mayen has only been "inhabitated" since 1921 by 1859 # Norwegian meteorologists and maybe used the same time as Norway ever 1860 # since 1921.

In 1943 the Americans established a 1874 # radiolocating station on the island, called "Atlantic City". Possibly 1875 # the UTC offset changed during the war, but I think it unlikely that 1876 # Jan Mayen used German daylight-saving rules. 1877 # 1878 # Svalbard is more complicated, as it was raided in August 1941 by an 1879 # Allied party that evacuated the civilian population to England (says 1880 # <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ 1881 # <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were 1882 # expelled on 1942-05-14.
