There was a photo 86# and a sketch map showing some of the sightlines involved. One paragraph 87# of the text said: 88# 89# `An old stone obelisk marking a forgotten terrestrial meridian stands 90# beside the river at Kew. In the 18th century, before time and longitude 91# was standardised by the Royal Observatory in Greenwich, scholars observed 92# this stone and the movement of stars from Kew Observatory nearby. They 93# made their calculations and set the time for the Horse Guards and Parliament, 94# but now the stone is obscured by scrubwood and can only be seen by walking 95# along the towpath within a few yards of it.' 96# 97# I have a one inch to one mile map of London and my estimate of the stone's 98# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should 99# be within about +-2". The Ordnance Survey grid reference is TQ172761. 100# 101# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] 102 103# From Paul Eggert <eggert@twinsun.com> (1993-11-18): 104# 105# Howse writes that Britain was the first country to use standard time. 106# The railways cared most about the inconsistencies of local mean time, 107# and it was they who forced a uniform time on the country. 108# The original idea was credited to Dr. William Hyde Wollaston (1766-1828) 109# and was popularized by Abraham Follett Osler (1808-1903). 110# The first railway to adopt London time was the Great Western Railway 111# in November 1840; other railways followed suit, and by 1847 most 112# (though not all) railways used London time. On 1847-09-22 the 113# Railway Clearing House, an industry standards body, recommended that GMT be 114# adopted at all stations as soon as the General Post Office permitted it. 115# The transition occurred on 12-01 for the L&NW, the Caledonian, 116# and presumably other railways; the January 1848 Bradshaw's lists many 117# railways as using GMT. By 1855 the vast majority of public 118# clocks in Britain were set to GMT (though some, like the great clock 119# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, 120# one for local time and one for GMT). The last major holdout was the legal 121# system, which stubbornly stuck to local time for many years, leading 122# to oddities like polls opening at 08:13 and closing at 16:13. 123# The legal system finally switched to GMT when the Statutes (Definition 124# of Time) Act took effect; it received the Royal Assent on 1880-08-02. 125# 126# In the tables below, we condense this complicated story into a single 127# transition date for London, namely 1847-12-01. We don't know as much 128# about Dublin, so we use 1880-08-02, the legal transition time. 129 130# From Paul Eggert (1999-01-30): 131# Summer Time was first seriously proposed by William Willett (1857-1915), 132# a London builder and member of the Royal Astronomical Society 133# who circulated a pamphlet ``The Waste of Daylight'' (1907) 134# that proposed advancing clocks 20 minutes on each of four Sundays in April, 135# and retarding them by the same amount on four Sundays in September. 136# A bill was drafted in 1909 and introduced in Parliament several times, 137# but it met with ridicule and opposition, especially from farming interests. 138# One-hour Summer Time was eventually adopted as a wartime measure in 1916. 139# See: 140# <a href="http://www.the-times.co.uk/news/pages/tim/2000/05/18/x-timcrtcrt01011.html"> 141# Summer Time Arrives Early, The Times (2000-05-18) 142# </a> 143# A monument was erected in 1927 to Willett, in an open space in a 45-acre wood 144# near Chiselhurst, Kent that was purchased by popular subscription and open 145# to the public. 146 147# From Paul Eggert (1996-09-03): 148# The OED Supplement says that the English originally said ``Daylight Saving'' 149# when they were debating the adoption of DST in 1908; but by 1916 this 150# term appears only in quotes taken from DST's opponents, whereas the 151# proponents (who eventually won the argument) are quoted as using ``Summer''. 152 153# From Arthur David Olson (1989-01-19): 154# 155# A source at the British Information Office in New York avers that it's 156# known as "British" Summer Time in all parts of the United Kingdom. 157 158# Date: 4 Jan 89 08:57:25 GMT (Wed) 159# From: Jonathan Leffler <nih-csl!uunet!mcvax!sphinx.co.uk!john> 160# [British Summer Time] is fixed annually by Act of Parliament. 161# If you can predict what Parliament will do, you should be in 162# politics making a fortune, not computing. 163 164# From Chris Carrier <72157.3334@CompuServe.COM> (1996-06-14): 165# I remember reading in various wartime issues of the London Times the 166# acronym BDST for British Double Summer Time. Look for the published 167# time of sunrise and sunset in The Times, when BDST was in effect, and 168# if you find a zone reference it will say, "All times B.D.S.T." 169 170# From Joseph S. Myers (1999-09-02): 171# ... some military cables (WO 219/4100 - this is a copy from the 172# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516) 173# agree that the usage is BDST (this appears in a message dated 17 Feb 1945). 174 175# From Joseph S. Myers (2000-10-03): 176# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir 177# Alexander Maxwell of the Home Office asking whether there was any 178# official designation; the reply of the 21st was that there wasn't 179# but he couldn't think of anything better than the "Double British 180# Summer Time" that the BBC had been using informally. 181# http://student.cusu.cam.ac.uk/~jsm28/british-time/bbc-19410418.png 182# http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png 183 184# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): 185# [N]o official designation has as far as I know been adopted for the time 186# which is to be introduced in May.... 187# I cannot think of anything better than "Double British Summer Time" 188# which could not be said to run counter to any official description. 189 190# From Paul Eggert (2000-10-02): 191# Howse writes (p 157) `DBST' too, but `BDST' seems to have been common 192# and follows the more usual convention of putting the location name first, 193# so we use `BDST'. 194 195# Peter Ilieve <peter@aldie.co.uk> (1998-04-19) described at length 196# the history of summer time legislation in the United Kingdom. 197# Since 1998 Joseph S.

212# 213# For lack of other data, we'll follow Shanks for Eire in 1940-1948. 214# 215# Given Ilieve and Myers's data, the following claims by Shanks are incorrect: 216# * Wales did not switch from GMT to daylight saving time until 217# 1921 Apr 3, when they began to conform with the rest of Great Britain. 218# Actually, Wales was identical after 1880. 219# * Eire had two transitions on 1916 Oct 1. 220# It actually just had one transition. 221# * Northern Ireland used single daylight saving time throughout WW II. 222# Actually, it conformed to Britain. 223# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18. 224# Actually, that date saw the usual switch to summer time. 225# Standard time was not changed until 1968-10-27 (the clocks didn't change). 226# 227# Here is another incorrect claim by Shanks: 228# * Jersey, Guernsey, and the Isle of Man did not switch from GMT 229# to daylight saving time until 1921 Apr 3, when they began to 230# conform with Great Britain. 231# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise. 232# 233# The following claim by Shanks is possible though doubtful; 234# we'll ignore it for now. 235# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00. 236# 237# 238# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.

245 246# From Paul Eggert (1999-03-28): 247# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31) 248# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time 249# (CT), equivalent to French civil time. 250# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that 251# trains between Dollands Moor (the freight facility next door) 252# and Frethun run in CT. 253# My admittedly uninformed guess is that the terminal has two authorities, 254# the French concession operators and the British civil authorities, 255# and that the time depends on who you're talking to. 256# If, say, the British police were called to the station for some reason, 257# I would expect the official police report to use GMT/BST and not CET/CEST. 258# This is a borderline case, but for now let's stick to GMT/BST. 259 260# From an anonymous contributor (1996-06-02): 261# The law governing time in Ireland is under Statutory Instrument SI 395/94, 262# which gives force to European Union 7th Council Directive # 94/21/EC. 263# Under this directive, the Minister for Justice in Ireland makes appropriate 264# regulations.

From 1909-05-01 (00:00:00 1415# Amsterdam mean time) onwards, the whole of the Netherlands (including 1416# the Dutch railways) was required by law to observe Amsterdam mean time 1417# (19 minutes 32.13 seconds ahead of GMT). This had already been the 1418# common practice (except for the railways) for many decades but it was 1419# not until 1909 when the Dutch government finally defined this by law. 1420# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and 1421# was generally known as Dutch Time ("Nederlandse Tijd"). 1422# 1423# (2001-04-08): 1424# 1892-05-01 was the date when the Dutch railways were by law required to 1425# observe GMT while the remainder of the Netherlands adhered to the common 1426# practice of following Amsterdam mean time. 1427# 1428# (2001-04-09): 1429# In 1835 the authorities of the province of North Holland requested the 1430# municipal authorities of the towns and cities in the province to observe 1431# Amsterdam mean time but I do not know in how many cases this request was 1432# actually followed. 1433# 1434# From 1852 onwards the Dutch telegraph offices were by law required to 1435# observe Amsterdam mean time. As the time signals from the observatory of 1436# Leiden were also distributed by the telegraph system, I assume that most 1437# places linked up with the telegraph (and railway) system automatically 1438# adopted Amsterdam mean time. 1439# 1440# Although the early Dutch railway companies initially observed a variety 1441# of times, most of them had adopted Amsterdam mean time by 1858 but it 1442# was not until 1866 when they were all required by law to observe 1443# Amsterdam mean time. 1444 1445# The data before 1945 are taken from |

1502 1503# From Steffen Thorsen (2001-05-01): 1504# Although I could not find it explicitly, it seems that Jan Mayen and 1505# Svalbard have been using the same time as Norway at least since the 1506# time they were declared as parts of Norway. Svalbard was declared 1507# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan 1508# Mayen by law of 1930-02-27 no 2, section 2. (From 1509# http://www.lovdata.no/all/nl-19250717-011.html and 1510# http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation 1511# for normal/standard time in Norway is from 1894-06-29 no 1 (came 1512# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a 1513# part of this law since 1925/1930. (From 1514# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been 1515# able to find if Jan Mayen used a different time zone (e.g. -0100) 1516# before 1930. Jan Mayen has only been "inhabitated" since 1921 by 1517# Norwegian meteorologists and maybe used the same time as Norway ever 1518# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since 1519# before 1895, and therefore probably changed the local time somewhere 1520# between 1895 and 1925 (inclusive). 1521 1522# From Paul Eggert (2001-05-01): 1523# 1524# Actually, Jan Mayen was never occupied by Germany during World War II, 1525# so it must have diverged from Oslo time during the war, as Olso was 1526# keeping Berlin time. 1527# 1528# <http://home.no.net/janmayen/history.htm> says that the meteorologists 1529# burned down their station in 1940 and left the island, but returned in 1530# 1941 with a small Norwegian garrison and continued operations despite 1531# frequent air ttacks from Germans. In 1943 the Americans established a 1532# radiolocating station on the island, called "Atlantic City". Possibly 1533# the UTC offset changed during the war, but I think it unlikely that 1534# Jan Mayen used German daylight-saving rules. 1535# 1536# Svalbard is more complicated, as it was raided in August 1941 by an 1537# Allied party that evacuated the civilian population to England (says 1538# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ 1539# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were 1540# expelled on 1942-05-14. However, small parties of Germans did return, 1541# and according to Wilhelm Dege's book "War North of 80" (1954) 1542# <http://www.utpress.utoronto.ca/publishing/rights/dege_warnorthof80.htm> 1543# the German armed forces at the Svalbard weather station code-named 1544# Haudegen did not surrender to the Allies until September 1945. 1545# 1546# All these events predate our cutoff date of 1970. Unless we can 1547# come up with more definitive info about the timekeeping during the 1548# war years it's probably best just do do the following for now: |

2015 2016# From Ivan Nilsson (2001-04-13), superseding Shanks: 2017# 2018# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879: 2019# From the beginning of 1879 (that is 01-01 00:00) the time for all 2020# places in the country is "the mean solar time for the meridian at 2021# three degrees, or twelve minutes of time, to the west of the 2022# meridian of the Observatory of Stockholm". The law is dated 1878-05-31. 2023# 2024# The observatory at that time had the meridian 18 degrees 03' 30" 2025# eastern longitude = 01:12:14 in time. Less 12 minutes gives the 2026# national standard time as 01:00:14 ahead of GMT.... 2027# 2028# About the beginning of CET in Sweden. The lawtext ("Svensk 2029# forfattningssamling 1899, no 44") states, that "from the beginning 2030# of 1900... ... the same as the mean solar time for the meridian at 2031# the distance of one hour of time from the meridian of the English 2032# observatory at Greenwich, or at 12 minutes 14 seconds to the west 2033# from the meridian of the Observatory of Stockholm". The law is dated 2034# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time 2035# in Sweden is 01:00:00 ahead of GMT. 2036# 2037# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states 2038# that "1916-05-15 is considered to begin one hour earlier". It is 2039# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00.... 2040# Further the law says, that "1916-09-30 is considered to end one hour later". 2041# 2042# The laws regulating [DST] are available on the site of the Swedish 2043# Parliament beginning with 1985 - the laws regulating 1980/1984 are 2044# not available on the site (to my knowledge they are only available 2045# in Swedish): <http://www.riksdagen.se/english/work/sfst.asp> (type 2046# "sommartid" without the quotes in the field "Fritext" and then click 2047# the Sok-button). 2048# 2049# (2001-05-13): 2050# 2051# I have now found a newspaper stating that at 1916-10-01 01:00 2052# summertime the church-clocks etc were set back one hour to show 2053# 1916-10-01 00:00 standard time. The article also reports that some 2054# people thought the switch to standard time would take place already 2055# at 1916-10-01 00:00 summer time, but they had to wait for another 2056# hour before the event took place. 2057# 2058# Source: The newspaper "Dagens Nyheter", 1916-10-01, page 7 upper left. 2059 |
