66# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about

86#
87# Howse writes that Britain was the first country to use standard time.
88# The railways cared most about the inconsistencies of local mean time,
89# and it was they who forced a uniform time on the country.
90# The original idea was credited to Dr. William Hyde Wollaston (1766-1828);
91# it was popularized in 1840 by Capt. Basil Hall, RN (1788-1844),
92# famed explorer and former Commissioner for Longitude.
93# The first railway to adopt London time was the Great Western Railway

112# Summer Time was first seriously proposed by William Willett (1857-1915),
113# a London builder who circulated a pamphlet ``Waste of Daylight'' (1907)
114# that proposed advancing clocks 20 minutes on each of four Sundays in April,
115# and retarding them by the same amount on four Sundays in September.
116# A bill was drafted in 1909 and introduced in Parliament several times,
117# but it met with ridicule and opposition, especially from farming interests.
118# One-hour Summer Time was eventually adopted as a wartime measure in 1916.
119
120# From Paul Eggert (1996-09-03):
121# The OED Supplement says that the English originally said ``Daylight Saving''
122# when they were debating the adoption of DST in 1908; but by 1916 this
123# term appears only in quotes taken from DST's opponents, whereas the
124# proponents (who eventually won the argument) are quoted as using ``Summer''.

139# Our Government...couldn't...make a decision after the 1989 consultation
140# exercise about the UK changing its timezone so it just let things drift
141# (different from deciding to keep the status quo). According to the

143# and 1994 are:
144# Start End

158# It ends at 02:00 GMT on the morning of the day after the fourth Saturday
159# in October. (All the redundant `morning of the day ...' is in the Act.)
160# This is only of passing interest now as it will always be overridden by
161# an Order in Council (a Statutary Instrument, the SI thing mentioned above)

181# when very early services are held in many churches, it is proposed that

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

218# I now have the text of the Summer Time Act 1916, the granddaddy of them all.
219# It is headed: `An Act to provide for the Time in Great Britain and Ireland
220# being in advance of Greenwich and Dublin mean time respectively in the
221# summer months'.
222#
223# It specifies 21 May and 1 October for 1916 (both at 02:00 GMT) and whatever
224# dates an Order in Council may specify for subsequent years.

242# The Act doesn't say anything about Wales (or Scotland) so I would assert
243# that Shanks is wrong here. I would like to know why he thinks Wales
244# was different.
245#
246# It also confirms the fact that Ireland followed Dublin time back then,
247# and 25 minutes behind Greenwich, as Shanks has it, would be correct.

251# I now have before me, thanks to my learned legal friend Lorna, the text of
252# the Time (Ireland) Act 1916.
253#
254# It says that as from 2 AM Dublin Mean Time on 1 October 1916 the time
255# for general purposes in Ireland shall be the same as the rest of Great
256# Britain (ie. GMT with the Summer Time periods specified by the Summer Time

267# In a table of repeals in the Schedule to the Act it mentions the

272# From Peter Ilieve <peter@memex.co.uk> (1993-10-29):

274# My case is that, with the sole exception of Ireland in 1916 using Dublin
275# Mean Time, Summer Time has been uniform throughout the United Kingdom
276# ever since it first started in 1916.
277#
278# The United Kingdom is England, Wales and Scotland plus all of Ireland from
279# 1916 up to and including 1921, or plus Northern Ireland from 1922 to date.

434# (to be known as British standard time) shall be one hour in

436# possibly argue that the start time of BStandardT was 00:00 1968-10-27,

1285# Iceland
1286#
1287# From Adam David <adam@veda.is> (1993-11-06):
1288# The name of the timezone in Iceland for system / mail / news purposes is GMT.
1289#
1290# (1993-12-05):
1291# This material is paraphrased from the 1988 edition of the University of
1292# Iceland Almanak.
1293#
1294# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
1295# behind GMT. Previously, local mean solar time was used in different parts
1296# of Iceland, the almanak had been based on Reykjavik mean solar time which
1297# was 1 hour and 28 minutes behind GMT.
1298#
1299# "first day of winter" referred to [below] means the first day of the 26 weeks
1300# of winter, according to the old icelandic calendar that dates back to the
1301# time the norsemen first settled Iceland. The first day of winter is always
1302# Saturday, but is not dependent on the Julian or Gregorian calendars.
1303#
1304# (1993-12-10):
1305# I have a reference from the Oxford Icelandic-English dictionary for the
1306# beginning of winter, which ties it to the ecclesiastical calendar (and thus
1307# to the julian/gregorian calendar) over the period in question.
1308# the winter begins on the Saturday next before St. Luke's day
1309# (old style), or on St. Luke's day, if a Saturday.
1310# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
1311# might be a reference to the Julian calendar as opposed to Gregorian, or it
1312# might mean something else (???).
1313#
1314# From Paul Eggert <eggert@twinsun.com> (1993-12-09):
1315# The Iceland Almanak, Shanks and Whitman disagree on many points.
1316# We go with the Almanak, except for one claim from Shanks, namely that
1317# Reykavik was -1:28 from 1837 to 1908, local mean time before that.

1923#
1924# In 1700, Denmark made the transition from Julian to Gregorian. Sweden
1925# decided to *start* a transition in 1700 as well, but rather than have one of
1926# those unsightly calendar gaps :-), they simply decreed that the next leap
1927# year after 1696 would be in 1744 -- putting the whole country on a calendar
1928# different from both Julian and Gregorian for a period of 40 years.
1929#
1930# However, in 1704 something went wrong and the plan was not carried through;
1931# they did, after all, have a leap year that year. And one in 1708. In 1712
1932# they gave it up and went back to Julian, putting 30 days in February that
1933# year!...
1934#
1935# Then in 1753, Sweden made the transition to Gregorian in the usual manner,
1936# getting there only 13 years behind the original schedule.
1937#
1938# (A previous posting of this story was challenged, and Swedish readers
1939# produced the following references to support it: "Tiderakning och historia"
1940# by Natanael Beckman (1924) and "Tid, en bok om tiderakning och
1941# kalendervasen" by Lars-Olof Lode'n (no date was given).)
