# Howse writes (p 157) `DBST'; let's assume this is a typo.
-# From Peter Ilieve <peter@aldie.co.uk> (1998-04-19):
-# The following list attempts to show the complete history of Summer Time
-# legislation in the United Kingdom, and has quite a bit to say about
-# the Isle of Man and the Channel Islands as well.
-#
-# Things that I have not personally seen are marked (???). Things that
-# I haven't seen but Joseph Myers has are marked (jsm). The problem
-# with finding old Orders (rather than Acts) is that nobody seems to
-# keep the actual documents themselves, not even the Government. They
-# get bound into annual volumes, which are published, but by the time
-# this happens the Orders are mainly spent as the years they refer
-# to have come and gone, so they don't get included in the annual
-# volumes.
-#
-# Thanks are due to my learned legal friend Lorna Montgomerie, who dug out
-# the dusty old statutes, to Melanie Allison of the Ministry of Defence,
-# who provided the wartime regulations and a snippet of Hansard explaining
-# why double summer time started on a Monday in 1945 (it was Easter),
-# and to Joseph Myers <jsm28@cam.ac.uk>, who tracked down the Orders
-# up to 1945, some of the old Acts, and the first five EC Directives.
-#
-# Some definitions:
-#
-# Great Britain: England, Scotland and Wales
-# United Kingdom: Great Britain plus Ireland (up to 1922) or Northern
-# Ireland (since 1922)
-# S.I.: Statutory Instrument, the modern name for secondary legislation
-# S.R.&O.: Statutory Rules and Orders, the older name for secondary legislation
-#
-# Unless otherwise specified, Acts and secondary legislation are assumed
-# to apply throughout the United Kingdom, but not to the Isle of Man
-# or the Channel Islands.
-#
-# Some of the Acts and Orders I found in various libraries, and I don't
-# have copies. When I looked at them I was looking for dates and not things
-# like whether they applied to the Bailiwick of Jersey. I will try to
-# check these documents again.

-#
-# I have this quote from Hansard (the official record of the United Kingdom
-# Parliament), Oral Answers, 1 March 1945, cols 1559--60, explaining the
-# unusual start on a Monday:
-#
-# `58. Major Sir Goronwy Owen asked the Secretary of State for the Home
-# Department if he is now able to state the Government's proposals
-# regarding double summer time.
-#
-# [two other similar questions omitted]
-#
-# Mr. H. Morrison: The Government, in reviewing the matter, have
-# considered, [...] the conclusion has been reached that the adoption of
-# double summer time from the beginning of April is essential to the
-# maintenance of the war effort. [...] As 1st April is Easter Sunday,
-# when very early services are held in many churches, it is proposed that
-# double summer time shall start not in the night preceding Easter
-# Sunday, but in the night of Sunday-Monday so that it will operate from
-# Monday, 2nd April.'
-#
-# - S.R.&O. 1945, No. 1208
-#
-# An Order under the Emergency Powers (Defence) Acts, 1939 and 1940 revoking
-# a long list of things, including the Defence (Summer Time) Regulations, 1939.
-# This meant that Summer Time reverted to being set by the 1922 and 1925 Acts.
-# It was made on 28 September, early enough to end Summer Time on the
-# date defined by the 1925 Act: 7 October.
-#
-# - The Summer Time Act, 1947 (10 & 11 Geo. 6. c. 16)
-#
-# Came into force on 11 March 1947. Amended the Summer Time Acts, 1922 and
-# 1925 to change the dates of Summer Time and to introduce Double Summer Time
-# (although it doesn't give this, or any, name for this period of 2 hour
-# offset from GMT). Dates are given for 1947 only and are: 02:00 GMT Sunday
-# 16 March, 01:00 GMT Sunday 13 April, 01:00 GMT Sunday 10 August, and 02:00
-# Sunday 2 November. It gave a power to make Orders for subsequent years,
-# both to vary the dates and to continue Double Summer Time. It applied
-# to the Isle of Man and the Channel Islands.
-#
-# - Summer Time Order, 1948 (S.I. 1948/495)
-#
-# An Order made under the Summer Time Act, 1947. Gave dates for 1948 of
-# 14 March and 31 October, both at 02:00 GMT.
-#
-# Although the 1947 Act had legislated for Double Summer Time, this was
-# not continued after 1947.

-# - Summer Time Order, 1949 (S.I. 1949/373)

-#
-# - Summer Time Order, 1952 (S.I. 1952/451)
-#
-# Another Order made under the Summer Time Act, 1947. Gave dates for 1952
-# of 20 April and 26 October, both at 02:00 GMT.
-#
-# This is the last of this run of Orders, so for 1953 things reverted
-# to the 1922 and 1925 Acts.
-#
-# - The Interpretation Act (Northern Ireland), 1954 (1954 c. 33 (N.I.)) (???)
-#
-# I presume that section 39 of this Act is similar to section 9 of the
-# Interpretation Act, 1978 (listed below) in specifying GMT as the
-# legal time in Northern Ireland, replacing the Time (Ireland) Act, 1916.
-#
-# - Summer Time Order, 1961 (S.I. 1961/71)
-#
-# Specified dates of 26 March and 29 October (02:00 GMT) for 1961

-# - Summer Time (1962) Order, 1961 (S.I. 1961/2465)
-#
-# Specified dates of 25 March to 28 October (02:00 GMT) for 1962.
-#
-# - Summer Time Order, 1963 (S.I. 1963/81)
-#
-# Specified dates of 31 March to 27 October (02:00 GMT) for 1963.
-#
-# - Summer Time (1964) Order, 1963 (S.I. 1963/2101)
-#
-# Specified dates of 22 March to 25 October (02:00 GMT) for 1964.
-#
-# - Summer Time Order, 1964 (S.I. 1964/1201)
-#
-# Specified dates for three years (all 02:00 GMT):
-# 1965: 21 March to 24 October
-# 1966: 20 March to 23 October
-# 1967: 19 March to 29 October
-#
-# - Summer Time Order, 1967 (S.I. 1967/1148)
-# - Summer Time Order, 1968 (S.I. 1968/117)
-#
-# The first of these specifies dates for 1968 of 18 February for the United
-# Kingdom but 7 April for the Isle of Man, both ending on 27 October,
-# all at 02:00 GMT. The second Order changes the Isle of Man start date
-# to 18 February to match the United Kingdom.
-#
-# - The British Standard Time Act 1968 (1968 c. 45)
-#
-# This came into force on 27 October 1968 and continued summer time throughout
-# the year. It expired at 02:00 GMT on 31 October 1971, as specified in the
-# Act, as Parliament did not move to make this experment permanent.
-# It applied to the Isle of Man and the Channel Islands.
-#
-# Interestingly, it says baldly `This Act shall come into force on
-# 27 October 1968', without giving a time. As S1 of the Act merely
-# stated that `The time for general purposes in the United Kingdom
-# (to be known as British standard time) shall be one hour in
-# advance of Greenwich mean time throughout the year; ...' you could
-# possibly argue that the start time of BStandardT was 00:00 1968-10-27,
-# especially as the Act repealed the Summer Time Acts 1916--1947 in toto,
-# thereby destroying the authority of the Summer Time Order specifying
-# summer time in 1968.
-#
-# - The Manx Time Act 1968
-#
-# This is an Act of Tynwald (the Isle of Man Parliament) that said that
-# henceforth Manx time would be the same as the time in Great Britain.
-#
-# - The Summer Time Act 1972 (1972 c. 6)
-#
-# This specified a reversion to normal Summer Time behaviour with a start
-# date of the day after the third Saturday in March, unless that is Easter,
-# when it is the day after the second Saturday, and an end date of the day
-# after the fourth Saturday in October. Times are at 02:00 GMT, offset is
-# 1 hour. It gives the power to make Orders to vary these dates and
-# times. This Act is still in force and is the legal authority for
-# implementing the EC Directives in the United Kingdom.
-#
-# - The Interpretation Act 1978 (1978 c. 30)
-#
-# Section 9 of this Act replaces section 1 of the Statutes (Definition of
-# Time) Act, 1880 with very similar wording maintaining GMT as the legal
-# time in Great Britain. This does not apply in Northern Ireland (it
-# has its own Interpretation Act listed above).
-#
-# - Council Directive of 22 July 1980 on summertime arrangements (80/737/EEC)
-#
-# The first of the European Directives on Summer Time. It specified start
-# dates for 1981 and 1982. No agreement had been reached on end dates.
-# Only dates were given, there was no rule like `last Sunday in March'.
-# The main change for the United Kingdom was a move to a 01:00 GMT change
-# time. The dates:
-# 1981: 29 March
-# 1982: 28 March
-#
-# - Summer Time Order, 1980 (S.I. 1980/1089)
-#
-# Specified dates for 1981 and 1982, with the start dates as in the
-# EC Directive and all times 01:00 GMT:
-# 1981: 29 March to 25 October
-# 1982: 28 March to 24 October
-#
-# - Second Council Directive of 10 June 1982 on summertime arrangements
-# (82/399/EEC)
-#
-# The next European Directive. Specified dates for three years, 1983 to 1985.
-# Agreement still hadn't been reached on a common end date, and wouldn't
-# be until 1994 with the appeareance of the seventh Directive with a common
-# date for 1996 and beyond, but this time the Directive gave two sets of
-# end dates. The start date was specified by rule: the last Sunday in March.
-# All times were 01:00 GMT. The end dates were given without rule, as:
-# 1983: 25 September or 23 October
-# 1984: 30 September or 28 october
-# 1985: 29 September or 27 October
-#
-# - Summer Time Order, 1982 (S.I. 1982/1673)
-#
-# Implemented the second EC Directive, using the October end dates.
-# 1983: 27 March to 23 October
-# 1984: 25 March to 28 october
-# 1985: 31 March to 27 October
-#
-# - Third Council Directive of 12 December 1984 on summertime arrangements
-# (84/634/EEC)
-#
-# Specified start dates of the last Sunday in March and two sets of end
-# dates, last Sunday in September and fourth Sunday in October, all at
-# 01:00 GMT. The end dates were also specified as dates:
-# 1986: 28 September or 26 October
-# 1987: 27 September or 25 October
-# 1988: 25 September or 23 October
-#
-# - Summer Time Order, 1986 (S.I. 1986/223)
-#
-# Implemented the third EC Directive, using the October end dates.
-# 1986: 30 March to 26 October
-# 1987: 29 March to 25 October
-# 1988: 27 March to 23 October
-#
-# - Council Directive of 20 December 1985 amending Directive 84/634/EEC
-# on summertime arrangements (85/582/EEC)
-#
-# This was to do with the accession of Spain and Portugal to the EEC.
-# The previous directve had used wording like `Member States belonging
-# to the zero (Greenwich) time zone' when refering to the different
-# sets of end dates. Portugal was in that time zone but was not going
-# to follow the United Kingdom and Ireland dates, so the text was reworded
-# without any change to the dates themselves.
-#
-# - Fourth Council Directive of 22 December 1987 on summertime arrangements
-# (88/14/EEC)
-#
-# This Directive covered only a single year: 1989. My guess is that
-# this was because 1989 was one of the years when the historic United Kingdom
-# end date of the Sunday after the fourth Saturday in October differed from
-# the rule in the previous Directive of the fourth Sunday in October.
-# All times are 01:00 GMT. No rule was specified, specific dates were given:
-# 1989: 26 March to 24 September or 29 October
-#
-# - Summer Time Order, 1988 (S.I. 1988/931)
-#
-# Implemented the dates of 26 March to 29 October for 1989.
-#
-# - Fifth Council Directive of 21 December 1988 on summertime arrangements
-# (89/47/EEC)
-#
-# Covered the three years 1990 to 1992. All times are 01:00 GMT. Gave both
-# rules (last Sunday in March, last Sunday in September or fourth Sunday
-# in October) and specific dates:
-# 1990: 25 March to 30 September or 28 October
-# 1991: 31 March to 29 September or 27 October
-# 1992: 29 March to 27 September or 25 October
-#
-# - Summer Time Order, 1989 (S.I. 1989/985)
-#
-# Implemented the fifth Directive using the October end dates.
-#
-# - Sixth Council Directive 92/20/EEC of 26 March 1992 on summertime
-# arrangements
-#
-# Covered the two years 1993 and 1994. All times are 01:00 GMT. Specified
-# both rules (same as the fifth Directive) and specific dates:
-# 1993: 28 March to 26 September or 24 October
-# 1994: 27 March to 25 September or 23 October
-#
-# - Summer Time Order, 1992 (S.I. 1992/1729)
-#
-# Implemented the sixth Directive using the October end dates.
-#
-# - Seventh Directive 94/21/EC of the European Parliament and of the Council
-# of 30 May 1994 on summer-time arrangements
-#
-# Covered the three years 1995 to 1997. Agreement had finally been reached
-# on a common end date, to start in 1996. Both rules and dates were given.
-# The rules were the same last Sunday in March to last Sunday in September
-# or fourth Sunday in October for 1995, with the end rule changing to the
-# last Sunday in October for 1996 and 1997. The year 1995 was another of
-# the tricky ones where the EC and traditional United Kingdom rules differed
-# but this time the UK changed on the fourth Sunday, 22 October, earlier
-# than usual. All times are 01:00 GMT. Specific dates were also given:
-# 1995: 26 March to 24 September or 22 October
-# 1996: 31 March to 27 October
-# 1997: 30 March to 26 October
-#
-# - Summer Time Order 1994 (S.I. 1994/2798)
-#
-# Implements the seventh Directive using the October end date in 1995.
-# Applies also to the Bailiwick of Guernsey but not to the Bailiwick of
-# Jersey or the Isle of Man, which have their own (unspecified) legislation
-# on the subject.
-#
-# - Eighth Directive 97/44/EC of the European Parliament and of the Council
-# of 22 July 1997 on summer-time arrangements
-#
-# Covers four years: 1998 to 2001. All times are 01:00 GMT. Specifies both

-# I today found the 1916 summer time orders for the Channel Islands in
-# the Public Record Office (HO 45/10811/312364).... Alderney,
-# Jersey and Guernsey all enacted summer time for 1916 (and the
-# enactment for the Isle of Man is already noted). This doesn't
-# complete the resolution of timekeeping in the Channel Islands, since
-# 1917-1921 need to be resolved for the Channel Islands, and it isn't
-# clear whether the islands were using GMT or local time then. The
-# changes in Alderney and Guernsey were at the same 2am GMT time as
-# for Great Britain; the order for Jersey is more interesting.
-#
-# From Paul Eggert (1999-10-22):
-# Mark Brader kindly translated the 1916 Jersey order from the French.
-# It says that the 1916 transitions were 05-20 and 09-30 at midnight.
-# No doubt this was 24:00, two or three hours earlier than Great Britain.
-# It also says that after 1916 they'll sync with Great Britain.
-
-# From Joseph S. Myers (1999-09-28):
-# I have the 1918 orders for Guernsey, Alderney (both changing on same
-# dates as UK, 2am GMT) and Sark (same dates; start and end at 2am,
-# start "temps de Greenwich" (not specified as "temps moyen de
-# Greenwich" which was used in the other orders) and end in an
-# unspecified zone). For Jersey the same file (Public Record Office: HO
-# 45/10892/357138) includes letters to the effect that in 1918 and 1919
-# the States of Jersey agreed the same start and end dates as the UK
-# (times unspecified, and it was the 1916 Jersey order that specified
-# change at midnight of an unspecified zone).
