There was a photo 110# and a sketch map showing some of the sightlines involved. One paragraph 111# of the text said: 112# 113# 'An old stone obelisk marking a forgotten terrestrial meridian stands 114# beside the river at Kew. In the 18th century, before time and longitude 115# was standardised by the Royal Observatory in Greenwich, scholars observed 116# this stone and the movement of stars from Kew Observatory nearby. They 117# made their calculations and set the time for the Horse Guards and Parliament, 118# but now the stone is obscured by scrubwood and can only be seen by walking 119# along the towpath within a few yards of it.' 120# 121# I have a one inch to one mile map of London and my estimate of the stone's 122# position is 51 degrees 28' 30" N, 0 degrees 18' 45" W. The longitude should 123# be within about +-2". The Ordnance Survey grid reference is TQ172761. 124# 125# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] 126 127# From Paul Eggert (1993-11-18): 128# 129# Howse writes that Britain was the first country to use standard time. 130# The railways cared most about the inconsistencies of local mean time, 131# and it was they who forced a uniform time on the country. 132# The original idea was credited to Dr. William Hyde Wollaston (1766-1828) 133# and was popularized by Abraham Follett Osler (1808-1903). 134# The first railway to adopt London time was the Great Western Railway 135# in November 1840; other railways followed suit, and by 1847 most 136# (though not all) railways used London time. On 1847-09-22 the 137# Railway Clearing House, an industry standards body, recommended that GMT be 138# adopted at all stations as soon as the General Post Office permitted it. 139# The transition occurred on 12-01 for the L&NW, the Caledonian, 140# and presumably other railways; the January 1848 Bradshaw's lists many 141# railways as using GMT. By 1855 the vast majority of public 142# clocks in Britain were set to GMT (though some, like the great clock 143# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, 144# one for local time and one for GMT). The last major holdout was the legal 145# system, which stubbornly stuck to local time for many years, leading 146# to oddities like polls opening at 08:13 and closing at 16:13. 147# The legal system finally switched to GMT when the Statutes (Definition 148# of Time) Act took effect; it received the Royal Assent on 1880-08-02. 149# 150# In the tables below, we condense this complicated story into a single 151# transition date for London, namely 1847-12-01. We don't know as much 152# about Dublin, so we use 1880-08-02, the legal transition time. 153 154# From Paul Eggert (2014-07-19): 155# The ancients had no need for daylight saving, as they kept time 156# informally or via hours whose length depended on the time of year. 157# Daylight saving time in its modern sense was invented by the 158# New Zealand entomologist George Vernon Hudson (1867-1946), 159# whose day job as a postal clerk led him to value 160# after-hours daylight in which to pursue his research. 161# In 1895 he presented a paper to the Wellington Philosophical Society 162# that proposed a two-hour daylight-saving shift. See: 163# Hudson GV. On seasonal time-adjustment in countries south of lat. 30 deg. 164# Transactions and Proceedings of the New Zealand Institute. 1895;28:734 165# http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html 166# Although some interest was expressed in New Zealand, his proposal 167# did not find its way into law and eventually it was almost forgotten. 168# 169# In England, DST was independently reinvented by William Willett (1857-1915), 170# a London builder and member of the Royal Astronomical Society 171# who circulated a pamphlet "The Waste of Daylight" (1907) 172# that proposed advancing clocks 20 minutes on each of four Sundays in April, 173# and retarding them by the same amount on four Sundays in September. 174# A bill was drafted in 1909 and introduced in Parliament several times, 175# but it met with ridicule and opposition, especially from farming interests. 176# Later editions of the pamphlet proposed one-hour summer time, and 177# it was eventually adopted as a wartime measure in 1916. 178# See: Summer Time Arrives Early, The Times (2000-05-18). 179# A monument to Willett was unveiled on 1927-05-21, in an open space in 180# a 45-acre wood near Chislehurst, Kent that was purchased by popular 181# subscription and open to the public. On the south face of the monolith, 182# designed by G. W. Miller, is the William Willett Memorial Sundial, 183# which is permanently set to Summer Time. 184 185# From Winston Churchill (1934-04-28): 186# It is one of the paradoxes of history that we should owe the boon of 187# summer time, which gives every year to the people of this country 188# between 160 and 170 hours more daylight leisure, to a war which 189# plunged Europe into darkness for four years, and shook the 190# foundations of civilization throughout the world. 191# -- "A Silent Toast to William Willett", Pictorial Weekly; 192# republished in Finest Hour (Spring 2002) 1(114):26 193# http://www.winstonchurchill.org/images/finesthour/Vol.01%20No.114.pdf 194 195# From Paul Eggert (2015-08-08): 196# The OED Supplement says that the English originally said "Daylight Saving" 197# when they were debating the adoption of DST in 1908; but by 1916 this 198# term appears only in quotes taken from DST's opponents, whereas the 199# proponents (who eventually won the argument) are quoted as using "Summer". 200# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see: 201# Viscount Samuel. Leisure in a Democracy. Cambridge University Press 202# ISBN 978-1-107-49471-8 (1949, reissued 2015), p 8. 203 204# From Arthur David Olson (1989-01-19): 205# A source at the British Information Office in New York avers that it's 206# known as "British" Summer Time in all parts of the United Kingdom. 207 208# Date: 4 Jan 89 08:57:25 GMT (Wed) 209# From: Jonathan Leffler 210# [British Summer Time] is fixed annually by Act of Parliament. 211# If you can predict what Parliament will do, you should be in 212# politics making a fortune, not computing. 213 214# From Chris Carrier (1996-06-14): 215# I remember reading in various wartime issues of the London Times the 216# acronym BDST for British Double Summer Time. Look for the published 217# time of sunrise and sunset in The Times, when BDST was in effect, and 218# if you find a zone reference it will say, "All times B.D.S.T." 219 220# From Joseph S. Myers (1999-09-02): 221# ... some military cables (WO 219/4100 - this is a copy from the 222# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516) 223# agree that the usage is BDST (this appears in a message dated 17 Feb 1945). 224 225# From Joseph S. Myers (2000-10-03): 226# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir 227# Alexander Maxwell of the Home Office asking whether there was any 228# official designation; the reply of the 21st was that there wasn't 229# but he couldn't think of anything better than the "Double British 230# Summer Time" that the BBC had been using informally. 231# http://www.polyomino.org.uk/british-time/bbc-19410418.png 232# http://www.polyomino.org.uk/british-time/ho-19410421.png 233 234# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): 235# [N]o official designation has as far as I know been adopted for the time 236# which is to be introduced in May.... 237# I cannot think of anything better than "Double British Summer Time" 238# which could not be said to run counter to any official description. 239 240# From Paul Eggert (2000-10-02): 241# Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common 242# and follows the more usual convention of putting the location name first, 243# so we use 'BDST'. 244 245# Peter Ilieve (1998-04-19) described at length 246# the history of summer time legislation in the United Kingdom. 247# Since 1998 Joseph S.

Myers (1998-01-06): 252# 253# The legal time in the UK outside of summer time is definitely GMT, not UTC; 254# see Lord Tanlaw's speech 255# http://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0 256# (Lords Hansard 11 June 1997 columns 964 to 976). 257 258# From Paul Eggert (2006-03-22): 259# 260# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948. 261# 262# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger 263# are incorrect: 264# * Wales did not switch from GMT to daylight saving time until 265# 1921 Apr 3, when they began to conform with the rest of Great Britain. 266# Actually, Wales was identical after 1880. 267# * Eire had two transitions on 1916 Oct 1. 268# It actually just had one transition. 269# * Northern Ireland used single daylight saving time throughout WW II. 270# Actually, it conformed to Britain. 271# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18. 272# Actually, that date saw the usual switch to summer time. 273# Standard time was not changed until 1968-10-27 (the clocks didn't change). 274# 275# Here is another incorrect claim by Shanks & Pottenger: 276# * Jersey, Guernsey, and the Isle of Man did not switch from GMT 277# to daylight saving time until 1921 Apr 3, when they began to 278# conform with Great Britain. 279# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise. 280# 281# The following claim by Shanks & Pottenger is possible though doubtful; 282# we'll ignore it for now. 283# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00. 284# 285# 286# Whitman says Dublin Mean Time was -0:25:21, which is more precise than 287# Shanks & Pottenger. 288# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory 289# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was 290# to London. For example: 291# 292# "Timeball on the ballast office is down. Dunsink time." 293# -- James Joyce, Ulysses 294 295# "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time 296# was among various actions undertaken by the 'English' government that 297# would 'put the whole country into the SF (Sinn Féin) camp'.

The law/regulation 1975# for normal/standard time in Norway is from 1894-06-29 no 1 (came 1976# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a 1977# part of this law since 1925/1930.

Jan Mayen has only been "inhabited" since 1921 by 1981# Norwegian meteorologists and maybe used the same time as Norway ever 1982# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since 1983# before 1895, and therefore probably changed the local time somewhere 1984# between 1895 and 1925 (inclusive). 1985 1986# From Paul Eggert (2013-09-04): 1987# 1988# Actually, Jan Mayen was never occupied by Germany during World War II, 1989# so it must have diverged from Oslo time during the war, as Oslo was 1990# keeping Berlin time. 1991# 1992# <http://home.no.net/janmayen/history.htm> says that the meteorologists 1993# burned down their station in 1940 and left the island, but returned in 1994# 1941 with a small Norwegian garrison and continued operations despite 1995# frequent air attacks from Germans. In 1943 the Americans established a 1996# radiolocating station on the island, called "Atlantic City". Possibly 1997# the UT offset changed during the war, but I think it unlikely that 1998# Jan Mayen used German daylight-saving rules. 1999# 2000# Svalbard is more complicated, as it was raided in August 1941 by an 2001# Allied party that evacuated the civilian population to England (says 2002# <http://www.bartleby.com/65/sv/Svalbard.html>).

The law is dated 3293# 1899-06-16.
