# Britain (United Kingdom) and Ireland (Eire)
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (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 <eggert@twinsun.com> (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 (1999-01-30):
|
|
# 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.
|
|
# One-hour Summer Time was eventually adopted as a wartime measure in 1916.
|
|
|
|
# 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 <nih-csl!uunet!mcvax!sphinx.co.uk!john>
|
|
# [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 <72157.3334@CompuServe.COM> (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).
|
|
|
|
# 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.

|
# - The Statutes (Definition of Time) Act, 1880 (43 & 44 Vict. c. 9)
|
|
#
|
|
# 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.
|
|
#
|
|
# - The Statutory Time Act, 1883 (???)
|
|
#
|
|
# An Act of Tynwald, the Isle of Man Parliament. It appears to have
|
|
# 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.

# Specified a one hour offset from GMT (DMT in Ireland), dates of

|
#
|
|
# - The Time (Ireland) Act, 1916 (6 & 7 Geo. 5. c. 45)
|
|
#
|
|
# This abolished Dublin mean time at 02:00 DMT on Sunday 1 October 1916,
|
|
# bringing the whole of the United Kingdom onto GMT. As Ireland was behind
|
|
# GMT/BST at 02:00 DMT on 1 Oct Great Britain had already put the clocks back.
|
|
# Using Paul Eggert's suggestion of IST for Irish Summer Time and the figure
|
|
# derived from Whitman for the offset of IST from GMT (00:34:39) the sequence
|
|
# would have been:
|
|
# Dublin London
|

# 02:34:38 IST 02:59:59 BST
|

# 02:34:39 IST 02:00:00 GMT

# 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.'

|
#
|
|
# 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,

#
|
|
# - 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
|
|
#
|

#
|
|
# - 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:
|

|
# - 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

|
|
# - Third Council Directive of 12 December 1984 on summertime arrangements

|
|
#
|
|
# 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

|
|
# - 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

|
|
# 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:

|
# Implements the seventh Directive using the October end date in 1995.

# From Joseph S. Myers (1999-09-02):
|
|
# 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 (1999-10-06):
|
|
# 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.
|
|
# Presumably this was 24:00, two 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

# From Paul Eggert (1999-09-20):
|
|
#
|
|
# The date `20 April 1924' in the table of ``Summer Time: A
|
|
# Consultation Document'' (Cm 722, 1989) table is a transcription error;
|
|
# 20 April was an Easter Sunday. Shanks has 13 April, the correct date.
|
|
# Also, the table is not quite right for 1925 through 1938; the correct rules
|
|
# (which Shanks uses) are given in the Summer Time Acts of 1922 and 1925.
|
|
# Shanks and the UK Government paper disagree about the Apr 1956 transition;
|
|
# since we have no other data, and since Shanks was correct in the other
|
|
# points of disagreement about London, we'll believe Shanks for now.
|
|
# Also, for lack of other data, we'll follow Shanks for Eire in 1940-1948.
|
|
#
|
|
# Given Peter Ilieve's comments, the following claims by Shanks 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:
|
|
# * 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 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.
|
|
|
|
# From Paul Eggert (1999-03-28):
|
|
# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
|
|
# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
|
|
# (CT), equivalent to French civil time.
|
|
# Julian Hill (<news:36118128.5A14@virgin.net>, 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".

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

# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
|
|
# Except for Moscow after 1919-07-01, I invented the time zone abbreviations,
|
|
# and (unless otherwise specified) guessed what happened after 1991.
|
|
# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
|
|
# are from Andrey A. Chernov. The rest is from Shanks and the IATA.
|
|
#
|
|
# From Andrey A. Chernov <ache@nagual.ru> (1996-10-04):
|
|
# `MSK' and `MSD' were born and used initially on Moscow computers with
|
|
# Unix-like OSes by several developer groups (e.g. Demos group, Kiae group)....
|
|
# The next step was the UUCP network, the Relcom predecessor
|
|
# (used mainly for mail), and MSK/MSD was actively used there.
|
|
#
|
|
# From Chris Carrier <72157.3334@CompuServe.COM> (1996-10-30):
|
|
# According to a friend of mine who rode the Trans-Siberian Railroad from
|
|
# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
|
|
# still follows Moscow time, no matter where in Russia it is located.

# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep

# The information from Tom Hofmann is (as far as I know) not entirely correct.

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