I was not -# able to find any authoritative sources at the time, nor details if -# Gaza changed as well, but presumed Gaza to follow the same rules as -# the West Bank. - -# From Steffen Thorsen (2006-09-26): -# according to the Palestine News Network (2006-09-19): -# http://english.pnn.ps/index.php?option=com_content&task=view&id=596&Itemid=5 -# > The Council of Ministers announced that this year its winter schedule -# > will begin early, as of midnight Thursday.

We have other instances of ambiguity -# (e.g. "IST" denoting both "Israel Standard Time" and "Indian -# Standard Time"), and they are not likely to go away any time soon. -# In the old days, some software mistakenly relied on unique -# abbreviations, but this is becoming less true with time, and I don't -# think it's that important to cater to such software these days. -# -# On the other hand, there is another motivation for unambiguous -# abbreviations: it cuts down on human confusion. This is -# particularly true for Australia, where "EST" can mean one thing for -# time T and a different thing for time T plus 1 second. -# -# * Does the relevant legislation indicate which abbreviations should be used? -# -# Here I tend to think that things are a mess, just as they are in -# many other countries. We Americans are currently disagreeing about -# which abbreviation to use for the newly legislated Chamorro Standard -# Time, for example. -# -# Personally, I would prefer to use common practice; I would like to -# refer to legislation only for examples of common practice, or as a -# tiebreaker. -# -# * Do Australians more often use "Eastern Daylight Time" or "Eastern -# Summer Time"? Do they typically prefix the time zone names with -# the word "Australian"? -# -# My own impression is that both "Daylight Time" and "Summer Time" are -# common and are widely understood, but that "Summer Time" is more -# popular; and that the leading "A" is also common but is omitted more -# often than not. I just used AltaVista advanced search and got the -# following count of page hits: -# -# 1,103 "Eastern Summer Time" AND domain:au -# 971 "Australian Eastern Summer Time" AND domain:au -# 613 "Eastern Daylight Time" AND domain:au -# 127 "Australian Eastern Daylight Time" AND domain:au -# -# Here "Summer" seems quite a bit more popular than "Daylight", -# particularly when we know the time zone is Australian and not US, -# say. The "Australian" prefix seems to be popular for Eastern Summer -# Time, but unpopular for Eastern Daylight Time. -# -# For abbreviations, tools like AltaVista are less useful because of -# ambiguity. Many hits are not really time zones, unfortunately, and -# many hits denote US time zones and not Australian ones. But here -# are the hit counts anyway: -# -# 161,304 "EST" and domain:au -# 25,156 "EDT" and domain:au -# 18,263 "AEST" and domain:au -# 10,416 "AEDT" and domain:au -# -# 14,538 "CST" and domain:au -# 5,728 "CDT" and domain:au -# 176 "ACST" and domain:au -# 29 "ACDT" and domain:au -# -# 7,539 "WST" and domain:au -# 68 "AWST" and domain:au -# -# This data suggest that Australians tend to omit the "A" prefix in -# practice. The situation for "ST" versus "DT" is less clear, given -# the ambiguities involved. -# -# * How do Australians feel about the abbreviations in the tz database? -# -# If you just count Australians on this list, I count 2 in favor and 3 -# against. One of the "against" votes (David Keegel) counseled delay, -# saying that both AEST/AEDT and EST/EST are widely used and -# understood in Australia. - -# From Paul Eggert (1995-12-19): -# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. -# Mark Prior writes that his newspaper -# reports that NSW's fall 1995 change will occur at 2:00, -# but Robert Elz says it's been 3:00 in Victoria since 1970 -# and perhaps the newspaper's `2:00' is referring to standard time. -# For now we'll continue to assume 2:00s for changes since 1960. - -# From Eric Ulevik (1998-01-05): -# -# Here are some URLs to Australian time legislation.

The straight-line boundaries between Pacific -# island nations that are shown on many maps are based on an international -# convention, but are not legally binding national borders.... The date is -# governed by the IDL; therefore, even on the high seas, there may be some -# places as late as fourteen hours later than UTC. And, since the IDL is not -# an international standard, there are some places on the high seas where the -# correct date is ambiguous. - -# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): -# Before 1920, all ships kept local apparent time on the high seas by setting -# their clocks at night or at the morning sight so that, given the ship's -# speed and direction, it would be 12 o'clock when the Sun crossed the ship's -# meridian (12 o'clock = local apparent noon). During 1917, at the -# Anglo-French Conference on Time-keeping at Sea, it was recommended that all -# ships, both military and civilian, should adopt hourly standard time zones -# on the high seas.

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 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. -# -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> -# "A Silent Toast to William Willett", Pictorial Weekly -# </a> - -# 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.

(From -# http://www.lovdata.no/all/nl-19250717-011.html and -# http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation -# for normal/standard time in Norway is from 1894-06-29 no 1 (came -# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a -# part of this law since 1925/1930. (From -# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been -# able to find if Jan Mayen used a different time zone (e.g. -0100) -# before 1930. Jan Mayen has only been "inhabitated" since 1921 by -# Norwegian meteorologists and maybe used the same time as Norway ever -# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since -# before 1895, and therefore probably changed the local time somewhere -# between 1895 and 1925 (inclusive). - -# From Paul Eggert (2001-05-01): -# -# Actually, Jan Mayen was never occupied by Germany during World War II, -# so it must have diverged from Oslo time during the war, as Oslo was -# keeping Berlin time. -# -# <http://home.no.net/janmayen/history.htm> says that the meteorologists -# burned down their station in 1940 and left the island, but returned in -# 1941 with a small Norwegian garrison and continued operations despite -# frequent air ttacks from Germans. In 1943 the Americans established a -# radiolocating station on the island, called "Atlantic City".

The discrepancy between municipal time and railroad -# time was noted. - -# From Paul Eggert (2003-07-27): -# Willett (1914-03) notes that DST "has been in operation ... in the -# City of Moose Jaw, Saskatchewan, for one year." - -# From Paul Eggert (2006-03-22): -# Shanks & Pottenger say that since 1970 this region has mostly been as Regina. -# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972. -# Other western towns (e.g. Lloydminster) are like Edmonton. -# Matthews and Vincent (1998) write that Denare Beach and Creighton -# are like Winnipeg, in violation of Saskatchewan law. - -# From W.

In 1965 a provincial -# referendum favoured legislating common time practices. -# -# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of -# Saskatchewan 1978) was proclaimed, and established that the eastern -# part of Saskatchewan would use CST year round, that districts in -# northwest Saskatchewan would by default follow CST but could opt to -# follow Mountain Time rules (thus 1 hour difference in the winter and -# zero in the summer), and that districts in southwest Saskatchewan would -# by default follow MT but could opt to follow CST. -# -# It took a few years for the dust to settle (I know one story of a town -# on one time zone having its school in another, such that a mom had to -# serve her family lunch in two shifts), but presently it seems that only -# a few towns on the border with Alberta (e.g. Lloydminster) follow MT -# rules any more; all other districts appear to have used CST year round -# since sometime in the 1960s. - -# From Chris Walton (2006-06-26): -# The Saskatchewan time act which was last updated in 1996 is about 30 pages -# long and rather painful to read. -# http://www.qp.gov.sk.ca/documents/English/Statutes/Statutes/T14.pdf - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Regina 1918 only - Apr 14 2:00 1:00 D -Rule Regina 1918 only - Oct 31 2:00 0 S -Rule Regina 1930 1934 - May Sun>=1 0:00 1:00 D -Rule Regina 1930 1934 - Oct Sun>=1 0:00 0 S -Rule Regina 1937 1941 - Apr Sun>=8 0:00 1:00 D -Rule Regina 1937 only - Oct Sun>=8 0:00 0 S -Rule Regina 1938 only - Oct Sun>=1 0:00 0 S -Rule Regina 1939 1941 - Oct Sun>=8 0:00 0 S -Rule Regina 1942 only - Feb 9 2:00 1:00 W # War -Rule Regina 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule Regina 1945 only - Sep lastSun 2:00 0 S -Rule Regina 1946 only - Apr Sun>=8 2:00 1:00 D -Rule Regina 1946 only - Oct Sun>=8 2:00 0 S -Rule Regina 1947 1957 - Apr lastSun 2:00 1:00 D -Rule Regina 1947 1957 - Sep lastSun 2:00 0 S -Rule Regina 1959 only - Apr lastSun 2:00 1:00 D -Rule Regina 1959 only - Oct lastSun 2:00 0 S -# -Rule Swift 1957 only - Apr lastSun 2:00 1:00 D -Rule Swift 1957 only - Oct lastSun 2:00 0 S -Rule Swift 1959 1961 - Apr lastSun 2:00 1:00 D -Rule Swift 1959 only - Oct lastSun 2:00 0 S -Rule Swift 1960 1961 - Sep lastSun 2:00 0 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone America/Regina -6:58:36 - LMT 1905 Sep - -7:00 Regina M%sT 1960 Apr lastSun 2:00 - -6:00 - CST -Zone America/Swift_Current -7:11:20 - LMT 1905 Sep - -7:00 Canada M%sT 1946 Apr lastSun 2:00 - -7:00 Regina M%sT 1950 - -7:00 Swift M%sT 1972 Apr lastSun 2:00 - -6:00 - CST - - -# Alberta - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Edm 1918 1919 - Apr Sun>=8 2:00 1:00 D -Rule Edm 1918 only - Oct 31 2:00 0 S -Rule Edm 1919 only - May 27 2:00 0 S -Rule Edm 1920 1923 - Apr lastSun 2:00 1:00 D -Rule Edm 1920 only - Oct lastSun 2:00 0 S -Rule Edm 1921 1923 - Sep lastSun 2:00 0 S -Rule Edm 1942 only - Feb 9 2:00 1:00 W # War -Rule Edm 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule Edm 1945 only - Sep lastSun 2:00 0 S -Rule Edm 1947 only - Apr lastSun 2:00 1:00 D -Rule Edm 1947 only - Sep lastSun 2:00 0 S -Rule Edm 1967 only - Apr lastSun 2:00 1:00 D -Rule Edm 1967 only - Oct lastSun 2:00 0 S -Rule Edm 1969 only - Apr lastSun 2:00 1:00 D -Rule Edm 1969 only - Oct lastSun 2:00 0 S -Rule Edm 1972 1986 - Apr lastSun 2:00 1:00 D -Rule Edm 1972 2006 - Oct lastSun 2:00 0 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone America/Edmonton -7:33:52 - LMT 1906 Sep - -7:00 Edm M%sT 1987 - -7:00 Canada M%sT - - -# British Columbia - -# From Paul Eggert (2006-03-22): -# Shanks & Pottenger write that since 1970 most of this region has -# been like Vancouver. -# Dawson Creek uses MST.

-# From IATA SSIM (1996-02): -# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS), -# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ), -# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO), -# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL]. -# [The last three states are new to this issue of the IATA SSIM.] - -# From Gwillim Law (1996-10-07): -# Geography, history (Tocantins was part of Goias until 1989), and other -# sources of time zone information lead me to believe that AL, SE, and TO were -# always in BR1, and so the only change was whether or not they observed DST.... -# The earliest issue of the SSIM I have is 2/91. Each issue from then until -# 9/95 says that DST is observed only in the ten states I quoted from 9/95, -# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2 -# (UTC-4).... The other two time zones given for Brazil are BR3, which is -# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is -# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's -# become part of the state of Pernambuco). The boundary between BR1 and BR2 -# has never been clearly stated. They've simply been called East and West. -# However, some conclusions can be drawn from another IATA manual: the Airline -# Coding Directory, which lists close to 400 airports in Brazil. For each -# airport it gives a time zone which is coded to the SSIM. From that -# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE), -# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do -# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST. - -# From Marcos Tadeu (1998-09-27): -# <a href="http://pcdsh01.on.br/verao1.html"> -# Brazilian official page -# </a> - -# From Jesper Norgaard (2000-11-03): -# [For an official list of which regions in Brazil use which time zones, see:] -# http://pcdsh01.on.br/Fusbr.htm -# http://pcdsh01.on.br/Fusbrhv.htm - -# From Celso Doria via David Madeo (2002-10-09): -# The reason for the delay this year has to do with elections in Brazil. -# -# Unlike in the United States, elections in Brazil are 100% computerized and -# the results are known almost immediately. Yesterday, it was the first -# round of the elections when 115 million Brazilians voted for President, -# Governor, Senators, Federal Deputies, and State Deputies. Nobody is -# counting (or re-counting) votes anymore and we know there will be a second -# round for the Presidency and also for some Governors. The 2nd round will -# take place on October 27th. -# -# The reason why the DST will only begin November 3rd is that the thousands -# of electoral machines used cannot have their time changed, and since the -# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM, -# the Government decided to postpone DST, instead of changing the Constitution -# (maybe, for the next elections, it will be possible to change the clock)... - -# From Rodrigo Severo (2004-10-04): -# It's just the biannual change made necessary by the much hyped, supposedly -# modern Brazilian eletronic voting machines which, apparently, can't deal -# with a time change between the first and the second rounds of the elections. - -# From Steffen Thorsen (2007-09-20): -# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00: -# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975 - -# From Paul Schulze (2008-06-24): -# ...by law number 11.662 of April 24, 2008 (published in the "Diario -# Oficial da Uniao"...) in Brazil there are changes in the timezones, -# effective today (00:00am at June 24, 2008) as follows: -# -# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the -# part of the Amazonas state that had this timezone now being put to the -# timezone UTC+4 -# b) The whole Para state now is put at timezone UTC+3, instead of just -# part of it, as was before. -# -# This change follows a proposal of senator Tiao Viana of Acre state, that -# proposed it due to concerns about open television channels displaying -# programs inappropriate to youths in the states that had the timezone -# UTC+5 too early in the night. In the occasion, some more corrections -# were proposed, trying to unify the timezones of any given state. This -# change modifies timezone rules defined in decree 2.784 of 18 June, -# 1913. - -# From Rodrigo Severo (2008-06-24): -# Just correcting the URL: -# <a href="https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008"> -# https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008 -# </a> -# -# As a result of the above Decree I believe the America/Rio_Branco -# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall -# be created to represent the the west side of the Para State. I -# suggest this new timezone be called Santarem as the most -# important/populated city in the affected area. -# -# This new timezone would be the same as the Rio_Branco timezone up to -# the 2008/06/24 change which would be to UTC-3 instead of UTC-4. - -# From Alex Krivenyshev (2008-06-24): -# This is a quick reference page for New and Old Brazil Time Zones map. -# <a href="http://www.worldtimezone.com/brazil-time-new-old.php"> -# http://www.worldtimezone.com/brazil-time-new-old.php -# </a> -# -# - 4 time zones replaced by 3 time zones-eliminating time zone UTC- 05 -# (state Acre and the part of the Amazonas will be UTC/GMT- 04) - western -# part of Par state is moving to one timezone UTC- 03 (from UTC -04). - -# From Paul Eggert (2002-10-10): -# The official decrees referenced below are mostly taken from -# <a href="http://pcdsh01.on.br/DecHV.html"> -# Decretos sobre o Horario de Verao no Brasil -# </a>. - -# From Steffen Thorsen (2008-08-29): -# As announced by the government and many newspapers in Brazil late -# yesterday, Brazil will start DST on 2008-10-19 (need to change rule) and -# it will end on 2009-02-15 (current rule for Brazil is fine). Based on -# past years experience with the elections, there was a good chance that -# the start was postponed to November, but it did not happen this year. -# -# It has not yet been posted to http://pcdsh01.on.br/DecHV.html -# -# An official page about it: -# <a href="http://www.mme.gov.br/site/news/detail.do?newsId=16722"> -# http://www.mme.gov.br/site/news/detail.do?newsId=16722 -# </a> -# Note that this link does not always work directly, but must be accessed -# by going to -# <a href="http://www.mme.gov.br/first"> -# http://www.mme.gov.br/first -# </a> -# -# One example link that works directly: -# <a href="http://jornale.com.br/index.php?option=com_content&task=view&id=13530&Itemid=54"> -# http://jornale.com.br/index.php?option=com_content&task=view&id=13530&Itemid=54 -# (Portuguese) -# </a> -# -# We have a written a short article about it as well: -# <a href="http://www.timeanddate.com/news/time/brazil-dst-2008-2009.html"> -# http://www.timeanddate.com/news/time/brazil-dst-2008-2009.html -# </a> - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -# Decree <a href="http://pcdsh01.on.br/HV20466.htm">20,466</a> (1931-10-01) -# Decree <a href="http://pcdsh01.on.br/HV21896.htm">21,896</a> (1932-01-10) -Rule Brazil 1931 only - Oct 3 11:00 1:00 S -Rule Brazil 1932 1933 - Apr 1 0:00 0 - -Rule Brazil 1932 only - Oct 3 0:00 1:00 S -# Decree <a href="http://pcdsh01.on.br/HV23195.htm">23,195</a> (1933-10-10) -# revoked DST. -# Decree <a href="http://pcdsh01.on.br/HV27496.htm">27,496</a> (1949-11-24) -# Decree <a href="http://pcdsh01.on.br/HV27998.htm">27,998</a> (1950-04-13) -Rule Brazil 1949 1952 - Dec 1 0:00 1:00 S -Rule Brazil 1950 only - Apr 16 1:00 0 - -Rule Brazil 1951 1952 - Apr 1 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV32308.htm">32,308</a> (1953-02-24) -Rule Brazil 1953 only - Mar 1 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV34724.htm">34,724</a> (1953-11-30) -# revoked DST. -# Decree <a href="http://pcdsh01.on.br/HV52700.htm">52,700</a> (1963-10-18) -# established DST from 1963-10-23 00:00 to 1964-02-29 00:00 -# in SP, RJ, GB, MG, ES, due to the prolongation of the drought. -# Decree <a href="http://pcdsh01.on.br/HV53071.htm">53,071</a> (1963-12-03) -# extended the above decree to all of the national territory on 12-09. -Rule Brazil 1963 only - Dec 9 0:00 1:00 S -# Decree <a href="http://pcdsh01.on.br/HV53604.htm">53,604</a> (1964-02-25) -# extended summer time by one day to 1964-03-01 00:00 (start of school). -Rule Brazil 1964 only - Mar 1 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV55639.htm">55,639</a> (1965-01-27) -Rule Brazil 1965 only - Jan 31 0:00 1:00 S -Rule Brazil 1965 only - Mar 31 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV57303.htm">57,303</a> (1965-11-22) -Rule Brazil 1965 only - Dec 1 0:00 1:00 S -# Decree <a href="http://pcdsh01.on.br/HV57843.htm">57,843</a> (1966-02-18) -Rule Brazil 1966 1968 - Mar 1 0:00 0 - -Rule Brazil 1966 1967 - Nov 1 0:00 1:00 S -# Decree <a href="http://pcdsh01.on.br/HV63429.htm">63,429</a> (1968-10-15) -# revoked DST. -# Decree <a href="http://pcdsh01.on.br/HV91698.htm">91,698</a> (1985-09-27) -Rule Brazil 1985 only - Nov 2 0:00 1:00 S -# Decree 92,310 (1986-01-21) -# Decree 92,463 (1986-03-13) -Rule Brazil 1986 only - Mar 15 0:00 0 - -# Decree 93,316 (1986-10-01) -Rule Brazil 1986 only - Oct 25 0:00 1:00 S -Rule Brazil 1987 only - Feb 14 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV94922.htm">94,922</a> (1987-09-22) -Rule Brazil 1987 only - Oct 25 0:00 1:00 S -Rule Brazil 1988 only - Feb 7 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV96676.htm">96,676</a> (1988-09-12) -# except for the states of AC, AM, PA, RR, RO, and AP (then a territory) -Rule Brazil 1988 only - Oct 16 0:00 1:00 S -Rule Brazil 1989 only - Jan 29 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV98077.htm">98,077</a> (1989-08-21) -# with the same exceptions -Rule Brazil 1989 only - Oct 15 0:00 1:00 S -Rule Brazil 1990 only - Feb 11 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV99530.htm">99,530</a> (1990-09-17) -# adopted by RS, SC, PR, SP, RJ, ES, MG, GO, MS, DF. -# Decree 99,629 (1990-10-19) adds BA, MT. -Rule Brazil 1990 only - Oct 21 0:00 1:00 S -Rule Brazil 1991 only - Feb 17 0:00 0 - -# <a href="http://pcdsh01.on.br/HV1991.htm">Unnumbered decree</a> (1991-09-25) -# adopted by RS, SC, PR, SP, RJ, ES, MG, BA, GO, MT, MS, DF. -Rule Brazil 1991 only - Oct 20 0:00 1:00 S -Rule Brazil 1992 only - Feb 9 0:00 0 - -# <a href="http://pcdsh01.on.br/HV1992.htm">Unnumbered decree</a> (1992-10-16) -# adopted by same states. -Rule Brazil 1992 only - Oct 25 0:00 1:00 S -Rule Brazil 1993 only - Jan 31 0:00 0 - -# Decree <a href="http://pcdsh01.on.br/HV942.htm">942</a> (1993-09-28) -# adopted by same states, plus AM. -# Decree <a href="http://pcdsh01.on.br/HV1252.htm">1,252</a> (1994-09-22;
