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. For example: -# -# "Timeball on the ballast office is down. Dunsink time." -# -- James Joyce, Ulysses - -# From Joseph S.

As the time signals from the observatory of -# Leiden were also distributed by the telegraph system, I assume that most -# places linked up with the telegraph (and railway) system automatically -# adopted Amsterdam mean time. -# -# Although the early Dutch railway companies initially observed a variety -# of times, most of them had adopted Amsterdam mean time by 1858 but it -# was not until 1866 when they were all required by law to observe -# Amsterdam mean time. - -# The data before 1945 are taken from -# <http://www.phys.uu.nl/~vgent/wettijd/wettijd.htm>. - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Neth 1916 only - May 1 0:00 1:00 NST # Netherlands Summer Time -Rule Neth 1916 only - Oct 1 0:00 0 AMT # Amsterdam Mean Time -Rule Neth 1917 only - Apr 16 2:00s 1:00 NST -Rule Neth 1917 only - Sep 17 2:00s 0 AMT -Rule Neth 1918 1921 - Apr Mon>=1 2:00s 1:00 NST -Rule Neth 1918 1921 - Sep lastMon 2:00s 0 AMT -Rule Neth 1922 only - Mar lastSun 2:00s 1:00 NST -Rule Neth 1922 1936 - Oct Sun>=2 2:00s 0 AMT -Rule Neth 1923 only - Jun Fri>=1 2:00s 1:00 NST -Rule Neth 1924 only - Mar lastSun 2:00s 1:00 NST -Rule Neth 1925 only - Jun Fri>=1 2:00s 1:00 NST -# From 1926 through 1939 DST began 05-15, except that it was delayed by a week -# in years when 05-15 fell in the Pentecost weekend. -Rule Neth 1926 1931 - May 15 2:00s 1:00 NST -Rule Neth 1932 only - May 22 2:00s 1:00 NST -Rule Neth 1933 1936 - May 15 2:00s 1:00 NST -Rule Neth 1937 only - May 22 2:00s 1:00 NST -Rule Neth 1937 only - Jul 1 0:00 1:00 S -Rule Neth 1937 1939 - Oct Sun>=2 2:00s 0 - -Rule Neth 1938 1939 - May 15 2:00s 1:00 S -Rule Neth 1945 only - Apr 2 2:00s 1:00 S -Rule Neth 1945 only - Sep 16 2:00s 0 - -# -# Amsterdam Mean Time was +00:19:32.13 exactly, but the .13 is omitted -# below because the current format requires GMTOFF to be an integer. -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Europe/Amsterdam 0:19:32 - LMT 1835 - 0:19:32 Neth %s 1937 Jul 1 - 0:20 Neth NE%sT 1940 May 16 0:00 # Dutch Time - 1:00 C-Eur CE%sT 1945 Apr 2 2:00 - 1:00 Neth CE%sT 1977 - 1:00 EU CE%sT - -# Norway -# http://met.no/met/met_lex/q_u/sommertid.html (2004-01) agrees with Shanks & -# Pottenger. -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Norway 1916 only - May 22 1:00 1:00 S -Rule Norway 1916 only - Sep 30 0:00 0 - -Rule Norway 1945 only - Apr 2 2:00s 1:00 S -Rule Norway 1945 only - Oct 1 2:00s 0 - -Rule Norway 1959 1964 - Mar Sun>=15 2:00s 1:00 S -Rule Norway 1959 1965 - Sep Sun>=15 2:00s 0 - -Rule Norway 1965 only - Apr 25 2:00s 1:00 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Europe/Oslo 0:43:00 - LMT 1895 Jan 1 - 1:00 Norway CE%sT 1940 Aug 10 23:00 - 1:00 C-Eur CE%sT 1945 Apr 2 2:00 - 1:00 Norway CE%sT 1980 - 1:00 EU CE%sT - -# Svalbard & Jan Mayen - -# From Steffen Thorsen (2001-05-01): -# Although I could not find it explicitly, it seems that Jan Mayen and -# Svalbard have been using the same time as Norway at least since the -# time they were declared as parts of Norway. 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.
