There was a photo 91# and a sketch map showing some of the sightlines involved. One paragraph 92# of the text said: 93# 94# `An old stone obelisk marking a forgotten terrestrial meridian stands 95# beside the river at Kew. In the 18th century, before time and longitude 96# was standardised by the Royal Observatory in Greenwich, scholars observed 97# this stone and the movement of stars from Kew Observatory nearby. They 98# made their calculations and set the time for the Horse Guards and Parliament, 99# but now the stone is obscured by scrubwood and can only be seen by walking 100# along the towpath within a few yards of it.' 101# 102# I have a one inch to one mile map of London and my estimate of the stone's 103# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should 104# be within about +-2". The Ordnance Survey grid reference is TQ172761. 105# 106# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] 107 108# From Paul Eggert (1993-11-18): 109# 110# Howse writes that Britain was the first country to use standard time. 111# The railways cared most about the inconsistencies of local mean time, 112# and it was they who forced a uniform time on the country. 113# The original idea was credited to Dr. William Hyde Wollaston (1766-1828) 114# and was popularized by Abraham Follett Osler (1808-1903). 115# The first railway to adopt London time was the Great Western Railway 116# in November 1840; other railways followed suit, and by 1847 most 117# (though not all) railways used London time. On 1847-09-22 the 118# Railway Clearing House, an industry standards body, recommended that GMT be 119# adopted at all stations as soon as the General Post Office permitted it. 120# The transition occurred on 12-01 for the L&NW, the Caledonian, 121# and presumably other railways; the January 1848 Bradshaw's lists many 122# railways as using GMT. By 1855 the vast majority of public 123# clocks in Britain were set to GMT (though some, like the great clock 124# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, 125# one for local time and one for GMT). The last major holdout was the legal 126# system, which stubbornly stuck to local time for many years, leading 127# to oddities like polls opening at 08:13 and closing at 16:13. 128# The legal system finally switched to GMT when the Statutes (Definition 129# of Time) Act took effect; it received the Royal Assent on 1880-08-02. 130# 131# In the tables below, we condense this complicated story into a single 132# transition date for London, namely 1847-12-01. We don't know as much 133# about Dublin, so we use 1880-08-02, the legal transition time. 134 135# From Paul Eggert (2003-09-27): 136# Summer Time was first seriously proposed by William Willett (1857-1915), 137# a London builder and member of the Royal Astronomical Society 138# who circulated a pamphlet ``The Waste of Daylight'' (1907) 139# that proposed advancing clocks 20 minutes on each of four Sundays in April, 140# and retarding them by the same amount on four Sundays in September. 141# A bill was drafted in 1909 and introduced in Parliament several times, 142# but it met with ridicule and opposition, especially from farming interests. 143# Later editions of the pamphlet proposed one-hour summer time, and 144# it was eventually adopted as a wartime measure in 1916. 145# See: Summer Time Arrives Early, The Times (2000-05-18). 146# A monument to Willett was unveiled on 1927-05-21, in an open space in 147# a 45-acre wood near Chislehurst, Kent that was purchased by popular 148# subscription and open to the public. On the south face of the monolith, 149# designed by G. W. Miller, is the...William Willett Memorial Sundial, 150# which is permanently set to Summer Time. 151 152# From Winston Churchill (1934-04-28): 153# It is one of the paradoxes of history that we should owe the boon of 154# summer time, which gives every year to the people of this country 155# between 160 and 170 hours more daylight leisure, to a war which 156# plunged Europe into darkness for four years, and shook the 157# foundations of civilization throughout the world. 158# -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> 159# "A Silent Toast to William Willett", Pictorial Weekly 160# </a> 161 162# From Paul Eggert (1996-09-03): 163# The OED Supplement says that the English originally said ``Daylight Saving'' 164# when they were debating the adoption of DST in 1908; but by 1916 this 165# term appears only in quotes taken from DST's opponents, whereas the 166# proponents (who eventually won the argument) are quoted as using ``Summer''. 167 168# From Arthur David Olson (1989-01-19): 169# 170# A source at the British Information Office in New York avers that it's 171# known as "British" Summer Time in all parts of the United Kingdom. 172 173# Date: 4 Jan 89 08:57:25 GMT (Wed) 174# From: Jonathan Leffler 175# [British Summer Time] is fixed annually by Act of Parliament. 176# If you can predict what Parliament will do, you should be in 177# politics making a fortune, not computing. 178 179# From Chris Carrier (1996-06-14): 180# I remember reading in various wartime issues of the London Times the 181# acronym BDST for British Double Summer Time. Look for the published 182# time of sunrise and sunset in The Times, when BDST was in effect, and 183# if you find a zone reference it will say, "All times B.D.S.T." 184 185# From Joseph S. Myers (1999-09-02): 186# ... some military cables (WO 219/4100 - this is a copy from the 187# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516) 188# agree that the usage is BDST (this appears in a message dated 17 Feb 1945). 189 190# From Joseph S. Myers (2000-10-03): 191# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir 192# Alexander Maxwell of the Home Office asking whether there was any 193# official designation; the reply of the 21st was that there wasn't 194# but he couldn't think of anything better than the "Double British 195# Summer Time" that the BBC had been using informally. 196# http://student.cusu.cam.ac.uk/~jsm28/british-time/bbc-19410418.png 197# http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png 198 199# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): 200# [N]o official designation has as far as I know been adopted for the time 201# which is to be introduced in May.... 202# I cannot think of anything better than "Double British Summer Time" 203# which could not be said to run counter to any official description. 204 205# From Paul Eggert (2000-10-02): 206# Howse writes (p 157) `DBST' too, but `BDST' seems to have been common 207# and follows the more usual convention of putting the location name first, 208# so we use `BDST'. 209 210# Peter Ilieve (1998-04-19) described at length 211# the history of summer time legislation in the United Kingdom. 212# Since 1998 Joseph S.

The law/regulation 1830# for normal/standard time in Norway is from 1894-06-29 no 1 (came 1831# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a 1832# part of this law since 1925/1930.

Jan Mayen has only been "inhabitated" since 1921 by 1836# Norwegian meteorologists and maybe used the same time as Norway ever 1837# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since 1838# before 1895, and therefore probably changed the local time somewhere 1839# between 1895 and 1925 (inclusive). 1840 1841# From Paul Eggert (2001-05-01): 1842# 1843# Actually, Jan Mayen was never occupied by Germany during World War II, 1844# so it must have diverged from Oslo time during the war, as Oslo was 1845# keeping Berlin time. 1846# 1847# <http://home.no.net/janmayen/history.htm> says that the meteorologists 1848# burned down their station in 1940 and left the island, but returned in 1849# 1941 with a small Norwegian garrison and continued operations despite 1850# frequent air ttacks from Germans. In 1943 the Americans established a 1851# radiolocating station on the island, called "Atlantic City". Possibly 1852# the UTC offset changed during the war, but I think it unlikely that 1853# Jan Mayen used German daylight-saving rules. 1854# 1855# Svalbard is more complicated, as it was raided in August 1941 by an 1856# Allied party that evacuated the civilian population to England (says 1857# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ 1858# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were 1859# expelled on 1942-05-14. However, small parties of Germans did return, 1860# and according to Wilhelm Dege's book "War North of 80" (1954) 1861# <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html> 1862# the German armed forces at the Svalbard weather station code-named 1863# Haudegen did not surrender to the Allies until September 1945. 1864# 1865# All these events predate our cutoff date of 1970.
