-# From Peter Ilieve <peter@memex.co.uk> (1993-09-03):
-#
-# Our Government...couldn't...make a decision after the 1989 consultation
-# exercise about the UK changing its timezone so it just let things drift
-# (different from deciding to keep the status quo).  According to the
-# Summer Time Order 1992 (SI 1992/1729) the dates of Summer Time for 1993
-# and 1994 are:
-#	Start		End
-# 1993	28 March	24 October
-# 1994	27 March	23 October
-# All start and end times are at 01:00 GMT.
-#
-# There [was] an error in your tables for the start and end times prior to 1981.
-# The UK always used to change at 02:00 GMT. In 1981 it changed to 01:00 GMT
-# as a part of EC harmonisation and has remained at that time since.
-#
-# I have found the default algorithm for UK Summer Time, it is in the
-# Summer Time Act 1972. Section 1 states that in the absence of an Order
-# in Council Summer Time starts at 02:00 GMT on the morning of the day
-# after the third Saturday in March, unless that day is Easter Day, in
-# which case it is the morning of the day after the second Saturday.
-# It ends at 02:00 GMT on the morning of the day after the fourth Saturday
-# in October. (All the redundant `morning of the day ...' is in the Act.)
-# This is only of passing interest now as it will always be overridden by
-# an Order in Council (a Statutory Instrument, the SI thing mentioned above)
-# to specify the EC specified dates.

-# from Hansard (the official record of the UK Parliament), Oral Answers,
-# 1 March 1945, cols 1559--60:
-#
-# `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.'

+# From Peter Ilieve <peter@aldie.co.uk> (1998-01-12):
+# 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.
 #
-# The ending rule here doesn't match the EC rules, which specify the fourth
-# Sunday in October for the UK and Eire. The `fourth Sunday' rule wasn't
-# followed in 1989, but then the sixth EC directive wasn't in force then
-# and I don't know what previous ones said. 1995 is the next year with
-# the 4th Sun on 22 Oct, but that year isn't covered by the UK Summer Time
-# Order or the sixth EC directive. Your Oct Sun>=23 rule matches history
-# and with things only announced for 2 years or so in advance who knows
-# what will happen.
+# 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.
 #
-# There are renewed rumours that the Government here will make another
-# attempt at resolving this issue, which is what prompted me to start
-# asking the Home Office and the EC about it again. The EC categorically
-# state they are not asking anybody to change timezone, they only want
-# common start/end dates. The UK Govt. seem to want to change our zone
-# and blame the resulting fuss on the EC. Me, I think we should scrap
-# summer time completely, noon is when the Sun is overhead, and that should
-# be the end of it.
-
-# From Peter Ilieve <peter@memex.co.uk> (1993-10-22):
+# 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.
 #
-# I now have the text of the Summer Time Act 1916, the granddaddy of them all.
-# It is headed: `An Act to provide for the Time in Great Britain and Ireland
-# being in advance of Greenwich and Dublin mean time respectively in the
-# summer months'.
+# Some definitions:
 #
-# It specifies 21 May and 1 October for 1916 (both at 02:00 GMT) and whatever
-# dates an Order in Council may specify for subsequent years.
+# 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
 #
-# Section 4 states: `This act shall apply to Ireland in like manner as it
-# applies to Great Britain, with the substitution however of references
-# to Dublin mean time for references to Greenwich mean time.'
+# 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.
 #
-# Lorna, my learned legal friend who supplied it, also offers this quote
-# from Halsbury's Statutes on the extent of Acts:
+# 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.
 #
-# `An Act of the United Kingdom Parliament is to be construed prima facie
-# to apply to the whole of the United Kingdom and not to any place outside.
-# [...] The expression "United Kingdom" for this purpose includes (since
-# 1922) Great Britain (ie. England, Wales and Scotland) and Northern Ireland,
-# but it does not include the Channel Islands or the Isle of Man.'

-# She goes on to say the seminal event of 1922 was the establishment of
-# the Irish Free State, now called Eire.
+# - The Statutes (Definition of Time) Act, 1880 (43 & 44 Vict. c. 9)
 #
-# The Act doesn't say anything about Wales (or Scotland) so I would assert
-# that Shanks is wrong here. I would like to know why he thinks Wales
-# was different.
+# Defined Greenwich mean time to be the standard time in Great Britain
+# and Dublin mean time to be the standard time in Ireland, superseding
+# various forms of local mean time.
 #
-# It also confirms the fact that Ireland followed Dublin time back then,
-# and 25 minutes behind Greenwich, as Shanks has it, would be correct.

+# - The Statutory Time Act, 1883 (???)
 #
-# I now have before me, thanks to my learned legal friend Lorna, the text of

+# defined the standard time on the Isle of Man as GMT but as I haven't
+# seen it I don't know if it used Greenwich mean time, some other definition,
+# or just said that Isle of Man time would be the same as in Great Britain.
 #
-# It says that as from 2 AM Dublin Mean Time on 1 October 1916 the time
-# for general purposes in Ireland shall be the same as the rest of Great
-# Britain (ie. GMT with the Summer Time periods specified by the Summer Time
-# Act 1916)....  As Ireland was behind GMT/BST at 02:00 DMT on 1 Oct GB would
-# have already put the clocks back. Using DST as Dublin Summer Time the
-# sequence would have been:
-# Dublin		London
-# 02:34 DST	02:59 BST
-# 02:35 DST	02:00 GMT
-# 02:59 DST	02:24 GMT

-# There are no changes to the dates we already have.

-# I now have a copy of the ... Eighth Directive 97/44/EC of the European
-# Parliament and of the Council of 22 July 1997 on summer-time arrangements.
-# It runs for 4 years, 1998--2001, and confirms the current rules of
-# last Sunday in March to last Sunday in October....
-# The directive does not apply in overseas territories of the Member States.
-# It says the Commission should produce a proposal for 2002 and beyond
-# by 1 Jan 2000 and this should be adopted by 1 Jan 2001.  I doubt that

-# The last time 4th Sun and Sun after 4th Sat differed was in 1989,
-# when 29 October was used.  That year was covered by a UK Summer Time Order
-# for only a single year and it looks as though there was a matching 4th EC
-# directive for just this year.  I don't have the text of the 5th EC

+# - 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

+# Only dates were given, there was no rule like `last Sunday in March'.

+# 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.

+# 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:

+#
+# - Summer Time Order, 1988 (S.I. 1988/931)

+#
+# Covered the three years 1990 to 1992. All times are 01:00 GMT. Gave both

+# 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
+# rules, last Sunday in March and last Sunday in October, and specific dates:
+#   1998: 29 March to 25 October
+#   1999: 28 March to 31 October
+#   2000: 26 March to 29 October
+#   2001: 25 March to 28 October

+# - Summer Time Order 1997 (S.I. 1997/2982)
+#
+# Implements the eighth Directive. Has the same text about the Isle of Man,
+# Guernsey and Jersey as the 1994 Order.

-# and ends at 01:00 GMT on the last Sunday in September, except for the UK
-# and Eire where it ends at 01:00 GMT on the fourth Sunday in October.

-# but as the sixth directive was supposed to appear by 1 Jan 92 and didn't
-# arrive til March I wouldn't hold your breath.
