77
78# From Peter Ilieve <peter@memex.co.uk> (1994-07-06):
79#
80# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
81# historical vistas along the Thames in west London. There was a photo
82# and a sketch map showing some of the sightlines involved. One paragraph
83# of the text said:
84#
85# `An old stone obelisk marking a forgotten terrestrial meridian stands
86# beside the river at Kew. In the 18th century, before time and longitude
87# was standardised by the Royal Observatory in Greenwich, scholars observed
88# this stone and the movement of stars from Kew Observatory nearby. They
89# made their calculations and set the time for the Horse Guards and Parliament,
90# but now the stone is obscured by scrubwood and can only be seen by walking
91# along the towpath within a few yards of it.'
92#
93# I have a one inch to one mile map of London and my estimate of the stone's
94# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
95# be within about +-2". The Ordnance Survey grid reference is TQ172761.
96#
97# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
98
99# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
100#
101# Howse writes that Britain was the first country to use standard time.
102# The railways cared most about the inconsistencies of local mean time,
103# and it was they who forced a uniform time on the country.
104# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
105# and was popularized by Abraham Follett Osler (1808-1903).
106# The first railway to adopt London time was the Great Western Railway
107# in November 1840; other railways followed suit, and by 1847 most
108# (though not all) railways used London time. On 1847-09-22 the
109# Railway Clearing House, an industry standards body, recommended that GMT be
110# adopted at all stations as soon as the General Post Office permitted it.
111# The transition occurred on 12-01 for the L&NW, the Caledonian,
112# and presumably other railways; the January 1848 Bradshaw's lists many
113# railways as using GMT. By 1855 the vast majority of public
114# clocks in Britain were set to GMT (though some, like the great clock
115# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
116# one for local time and one for GMT). The last major holdout was the legal
117# system, which stubbornly stuck to local time for many years, leading
118# to oddities like polls opening at 08:13 and closing at 16:13.
119# The legal system finally switched to GMT when the Statutes (Definition
120# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
121#
122# In the tables below, we condense this complicated story into a single
123# transition date for London, namely 1847-12-01. We don't know as much
124# about Dublin, so we use 1880-08-02, the legal transition time.
125
126# From Paul Eggert (1999-01-30):
127# Summer Time was first seriously proposed by William Willett (1857-1915),
128# a London builder and member of the Royal Astronomical Society
129# who circulated a pamphlet ``The Waste of Daylight'' (1907)
130# that proposed advancing clocks 20 minutes on each of four Sundays in April,
131# and retarding them by the same amount on four Sundays in September.
132# A bill was drafted in 1909 and introduced in Parliament several times,
133# but it met with ridicule and opposition, especially from farming interests.
134# One-hour Summer Time was eventually adopted as a wartime measure in 1916.

154# I remember reading in various wartime issues of the London Times the

181
182# From Paul Eggert (2000-02-17):
183#
184# For lack of other data, we'll follow Shanks for Eire in 1940-1948.
185#
186# Given Ilieve and Myers's data, the following claims by Shanks are incorrect:
187# * Wales did not switch from GMT to daylight saving time until
188# 1921 Apr 3, when they began to conform with the rest of Great Britain.
189# Actually, Wales was identical after 1880.
190# * Eire had two transitions on 1916 Oct 1.
191# It actually just had one transition.
192# * Northern Ireland used single daylight saving time throughout WW II.
193# Actually, it conformed to Britain.
194# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
195# Actually, that date saw the usual switch to summer time.
196# Standard time was not changed until 1968-10-27 (the clocks didn't change).
197#
198# Here is another incorrect claim by Shanks:
199# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
200# to daylight saving time until 1921 Apr 3, when they began to
201# conform with Great Britain.
202# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
203#
204# The following claim by Shanks is possible though doubtful;
205# we'll ignore it for now.
206# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
207#
208#
209# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
210
211# From Paul Eggert (1999-03-28):
212# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
213# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
214# (CT), equivalent to French civil time.
215# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
216# trains between Dollands Moor (the freight facility next door)
217# and Frethun run in CT.
218# My admittedly uninformed guess is that the terminal has two authorities,
219# the French concession operators and the British civil authorities,
220# and that the time depends on who you're talking to.
221# If, say, the British police were called to the station for some reason,
222# I would expect the official police report to use GMT/BST and not CET/CEST.
223# This is a borderline case, but for now let's stick to GMT/BST.
224
225# From an anonymous contributor (1996-06-02):
226# The law governing time in Ireland is under Statutory Instrument SI 395/94,

228# Under this directive, the Minister for Justice in Ireland makes appropriate
229# regulations. I spoke this morning with the Secretary of the Department of

719# a regulation of the Government of Estonia, No. 111 of 1989....
720#
721# From Peter Ilieve <peter@aldie.co.uk> (1996-10-28):
722# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
723# but a relative confirms that Estonia still switches at 02:00s, writing:]
724# ``I do not [know] exactly but there are some little different
725# (confusing) rules for International Air and Railway Transport Schedules
726# conversion in Sunday connected with end of summer time in Estonia....
727# A discussion is running about the summer time efficiency and effect on
728# human physiology. It seems that Estonia maybe will not change to
729# summer time next spring.''

732# <a href="http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390">
733# The 1998-09-22 Estonian time law
734# </a>
735# refers to the Eighth Directive and cites the association agreement between
736# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120).
737#
738# I also asked [my relative] whether they use any standard abbreviation
739# for their standard and summer times. He says no, they use "suveaeg"
740# (summer time) and "talveaeg" (winter time).

745# a council of the ruling coalition announced Sept. 6....
746# But what this could mean for Estonia's chances of joining the European
747# Union are still unclear. In 1994, the EU declared summer time compulsory

752# Regulation no. 301 (1999-10-12) obsoletes previous regulation

967#
968# From Adam David <adam@veda.is> (1993-11-06):
969# The name of the timezone in Iceland for system / mail / news purposes is GMT.
970#
971# (1993-12-05):
972# This material is paraphrased from the 1988 edition of the University of
973# Iceland Almanak.
974#
975# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
976# behind GMT. Previously, local mean solar time was used in different parts
977# of Iceland, the almanak had been based on Reykjavik mean solar time which
978# was 1 hour and 28 minutes behind GMT.
979#
980# "first day of winter" referred to [below] means the first day of the 26 weeks
981# of winter, according to the old icelandic calendar that dates back to the
982# time the norsemen first settled Iceland. The first day of winter is always
983# Saturday, but is not dependent on the Julian or Gregorian calendars.
984#
985# (1993-12-10):
986# I have a reference from the Oxford Icelandic-English dictionary for the
987# beginning of winter, which ties it to the ecclesiastical calendar (and thus
988# to the julian/gregorian calendar) over the period in question.
989# the winter begins on the Saturday next before St. Luke's day
990# (old style), or on St. Luke's day, if a Saturday.
991# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
992# might be a reference to the Julian calendar as opposed to Gregorian, or it
993# might mean something else (???).
994#
995# From Paul Eggert <eggert@twinsun.com> (1999-10-29):
996# The Iceland Almanak, Shanks and Whitman disagree on many points.
997# We go with the Almanak, except for one claim from Shanks, namely that
998# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

1106# I asked about this matter Scientific Secretary of the Institute of Astronomy

1108# correct data in juridical acts and I found some juridical documents about
1109# changes in the counting of time in Latvia from 1981....
1110#
1111# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
1112# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24

1127# Estonian SSR and Kaliningrad region of Russian Federation all year round the
1128# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia
1129# transition to summer time is performed on the last Sunday of March at 02:00

187# From Paul Eggert (2000-02-17):
188#
189# For lack of other data, we'll follow Shanks for Eire in 1940-1948.
190#
191# Given Ilieve and Myers's data, the following claims by Shanks are incorrect:
192# * Wales did not switch from GMT to daylight saving time until
193# 1921 Apr 3, when they began to conform with the rest of Great Britain.
194# Actually, Wales was identical after 1880.
195# * Eire had two transitions on 1916 Oct 1.
196# It actually just had one transition.
197# * Northern Ireland used single daylight saving time throughout WW II.
198# Actually, it conformed to Britain.
199# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
200# Actually, that date saw the usual switch to summer time.
201# Standard time was not changed until 1968-10-27 (the clocks didn't change).
202#
203# Here is another incorrect claim by Shanks:
204# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
205# to daylight saving time until 1921 Apr 3, when they began to
206# conform with Great Britain.
207# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
208#
209# The following claim by Shanks is possible though doubtful;
210# we'll ignore it for now.
211# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
212#
213#
214# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
215
216# From Paul Eggert (1999-03-28):
217# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
218# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
219# (CT), equivalent to French civil time.
220# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
221# trains between Dollands Moor (the freight facility next door)
222# and Frethun run in CT.
223# My admittedly uninformed guess is that the terminal has two authorities,
224# the French concession operators and the British civil authorities,
225# and that the time depends on who you're talking to.
226# If, say, the British police were called to the station for some reason,
227# I would expect the official police report to use GMT/BST and not CET/CEST.
228# This is a borderline case, but for now let's stick to GMT/BST.
229
230# From an anonymous contributor (1996-06-02):
231# The law governing time in Ireland is under Statutory Instrument SI 395/94,
232# which gives force to European Union 7th Council Directive # 94/21/EC.
233# Under this directive, the Minister for Justice in Ireland makes appropriate
234# regulations. I spoke this morning with the Secretary of the Department of
235# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
236# "Irish Summer Time", abbreviated to "IST".

721# From Peter Ilieve <peter@memex.co.uk> (1994-10-15):

723# [through 1994] and gives the legal authority for it,
724# a regulation of the Government of Estonia, No. 111 of 1989....
725#
726# From Peter Ilieve <peter@aldie.co.uk> (1996-10-28):
727# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
728# but a relative confirms that Estonia still switches at 02:00s, writing:]
729# ``I do not [know] exactly but there are some little different
730# (confusing) rules for International Air and Railway Transport Schedules
731# conversion in Sunday connected with end of summer time in Estonia....
732# A discussion is running about the summer time efficiency and effect on
733# human physiology. It seems that Estonia maybe will not change to
734# summer time next spring.''

736# From Peter Ilieve <peter@aldie.co.uk> (1998-11-04), heavily edited:
737# <a href="http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390">
738# The 1998-09-22 Estonian time law
739# </a>
740# refers to the Eighth Directive and cites the association agreement between
741# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120).
742#
743# I also asked [my relative] whether they use any standard abbreviation
744# for their standard and summer times. He says no, they use "suveaeg"
745# (summer time) and "talveaeg" (winter time).

747# From <a href="http://www.baltictimes.com/">The Baltic Times</a> (1999-09-09)

749# This year will mark the last time Estonia shifts to summer time,
750# a council of the ruling coalition announced Sept. 6....
751# But what this could mean for Estonia's chances of joining the European
752# Union are still unclear. In 1994, the EU declared summer time compulsory
753# for all member states until 2001. Brussels has yet to decide what to do
754# after that.

756# From Mart Oruaas (2000-01-29):
757# Regulation no. 301 (1999-10-12) obsoletes previous regulation

971# Iceland
972#
973# From Adam David <adam@veda.is> (1993-11-06):
974# The name of the timezone in Iceland for system / mail / news purposes is GMT.
975#
976# (1993-12-05):
977# This material is paraphrased from the 1988 edition of the University of
978# Iceland Almanak.
979#
980# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
981# behind GMT. Previously, local mean solar time was used in different parts
982# of Iceland, the almanak had been based on Reykjavik mean solar time which
983# was 1 hour and 28 minutes behind GMT.
984#
985# "first day of winter" referred to [below] means the first day of the 26 weeks
986# of winter, according to the old icelandic calendar that dates back to the
987# time the norsemen first settled Iceland. The first day of winter is always
988# Saturday, but is not dependent on the Julian or Gregorian calendars.
989#
990# (1993-12-10):
991# I have a reference from the Oxford Icelandic-English dictionary for the
992# beginning of winter, which ties it to the ecclesiastical calendar (and thus
993# to the julian/gregorian calendar) over the period in question.
994# the winter begins on the Saturday next before St. Luke's day
995# (old style), or on St. Luke's day, if a Saturday.
996# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
997# might be a reference to the Julian calendar as opposed to Gregorian, or it
998# might mean something else (???).
999#
1000# From Paul Eggert <eggert@twinsun.com> (1999-10-29):
1001# The Iceland Almanak, Shanks and Whitman disagree on many points.
1002# We go with the Almanak, except for one claim from Shanks, namely that
1003# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

1543# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
1544# are from Andrey A. Chernov. The rest is from Shanks, except we follow
1545# Chernov's report that 1992 DST transitions were Sat 23:00, not Sun 02:00s.

1547# From Andrey A. Chernov <ache@nagual.ru> (1996-10-04):
1548# `MSK' and `MSD' were born and used initially on Moscow computers with
1549# Unix-like OSes by several developer groups (e.g. Demos group, Kiae group)....
1550# The next step was the UUCP network, the Relcom predecessor
1551# (used mainly for mail), and MSK/MSD was actively used there.

1923# about DST in Europe. I was able to find all from about 1969.
1924#
1925# ...standardization on DST in Europe started in about 1977 with switches on
1926# first Sunday in April and last Sunday in September...
1927# In 1981 UK joined Europe insofar that
1928# the starting day for both shifted to last Sunday in March. And from 1982
1929# the whole of Europe used DST, with switch dates April 1 and October 1 in
1930# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
1931# dates...
1932#
1933# It should also be remembered that time-zones are not constants; e.g.
1934# Portugal switched in 1976 from MET (or CET) to WET with DST...
1935# Note also that though there were rules for switch dates not
1936# all countries abided to these dates, and many individual deviations
1937# occurred, though not since 1982 I believe. Another note: it is always
1938# assumed that DST is 1 hour ahead of normal time, this need not be the
1939# case; at least in the Netherlands there have been times when DST was 2 hours
1940# in advance of normal time.

1934#
1935# ...standardization on DST in Europe started in about 1977 with switches on
1936# first Sunday in April and last Sunday in September...
1937# In 1981 UK joined Europe insofar that
1938# the starting day for both shifted to last Sunday in March. And from 1982
1939# the whole of Europe used DST, with switch dates April 1 and October 1 in
1940# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
1941# dates...
1942#
1943# It should also be remembered that time-zones are not constants; e.g.
1944# Portugal switched in 1976 from MET (or CET) to WET with DST...
1945# Note also that though there were rules for switch dates not
1946# all countries abided to these dates, and many individual deviations
1947# occurred, though not since 1982 I believe. Another note: it is always
1948# assumed that DST is 1 hour ahead of normal time, this need not be the
1949# case; at least in the Netherlands there have been times when DST was 2 hours
1950# in advance of normal time.
