# Britain (United Kingdom) and Ireland (Eire)

# From Peter Ilieve (1994-07-06):

#

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

# historical vistas along the Thames in west London. 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...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.

# 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/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

# 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. Myers (2005-01-26):

# Irish laws are available online at www.irishstatutebook.ie.  These include

# various relating to legal time, for example:

# [These are all relative to the root, e.g., the first is

# <http://www.irishstatutebook.ie/ZZA13Y1923.html>.]

#

# (These are those I found, but there could be more.  In any case these

# should allow various updates to the comments in the europe file to cover

# the laws applicable in Ireland.)

#

# (Note that the time in the Republic of Ireland since 1968 has been defined

# in terms of standard time being GMT+1 with a period of winter time when it

# is GMT, rather than standard time being GMT with a period of summer time

# being GMT+1.)

# From Paul Eggert (1999-03-28):

# Clive Feather (<news:[email protected]>, 1997-03-31)

# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time

# (CT), equivalent to French civil time.

# Julian Hill (<news:[email protected]>, 1998-09-30) reports that

# trains between Dollands Moor (the freight facility next door)

# and Frethun run in CT.

# My admittedly uninformed guess is that the terminal has two authorities,

# the French concession operators and the British civil authorities,

# and that the time depends on who you're talking to.

# If, say, the British police were called to the station for some reason,

# I would expect the official police report to use GMT/BST and not CET/CEST.

# This is a borderline case, but for now let's stick to GMT/BST.

# From an anonymous contributor (1996-06-02):

# The law governing time in Ireland is under Statutory Instrument SI 395/94,

# which gives force to European Union 7th Council Directive # 94/21/EC.

# Under this directive, the Minister for Justice in Ireland makes appropriate

# regulations. I spoke this morning with the Secretary of the Department of

# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is

# "Irish Summer Time", abbreviated to "IST".

# From Jesper Norgaard Welen (2008-07-13):

#

# I found what is probably a typo of 2:00 which should perhaps be 2:00s

# in the C-Eur rule from tz database version 2008d (this part was

# corrected in version 2008d). The circumstancial evidence is simply the

# tz database itself, as seen below:

#

# Zone Europe/Paris 0:09:21 - LMT 1891 Mar 15  0:01

#    0:00 France WE%sT 1945 Sep 16  3:00

#

# Zone Europe/Monaco 0:29:32 - LMT 1891 Mar 15

#    0:00 France WE%sT 1945 Sep 16 3:00

#

# Zone Europe/Belgrade 1:22:00 - LMT 1884

#    1:00 1:00 CEST 1945 Sep 16  2:00s

#

# Rule France 1945 only - Sep 16  3:00 0 -

# Rule Belgium 1945 only - Sep 16  2:00s 0 -

# Rule Neth 1945 only - Sep 16 2:00s 0 -

#

# The rule line to be changed is:

#

# Rule C-Eur 1945 only - Sep 16  2:00 0 -

#

# It seems that Paris, Monaco, Rule France, Rule Belgium all agree on

# 2:00 standard time, e.g. 3:00 local time.  However there are no

# countries that use C-Eur rules in September 1945, so the only items

# affected are apparently these ficticious zones that translates acronyms

# CET and MET:

#

# Zone CET  1:00 C-Eur CE%sT

# Zone MET  1:00 C-Eur ME%sT

#

# It this is right then the corrected version would look like:
