2367c478bd9Sstevel@tonic-gate#     "The time change in Tierra del Fuego was a conflicted decision from
2377c478bd9Sstevel@tonic-gate#   the start.  The government had decreed that the measure would take
2387c478bd9Sstevel@tonic-gate#   effect on June 1, but a normative error forced the new time to begin
2397c478bd9Sstevel@tonic-gate#   three days earlier, from a Saturday to a Sunday....
2407c478bd9Sstevel@tonic-gate# Our understanding was that the change was originally scheduled to take place
2417c478bd9Sstevel@tonic-gate# on June 1 at 00:00 in Chubut, Santa Cruz, Tierra del Fuego (and some other
2427c478bd9Sstevel@tonic-gate# provinces).  Sunday was May 30, only two days earlier.  So the article
2437c478bd9Sstevel@tonic-gate# contains a contradiction.  I would give more credence to the Saturday/Sunday
2447c478bd9Sstevel@tonic-gate# date than the "three days earlier" phrase, and conclude that Tierra del
2457c478bd9Sstevel@tonic-gate# Fuego set its clocks back at 2004-05-30 00:00.

2846f8e8937SDan McDonald# The change is supposed to take place Monday the 21st at 0:00

3028593320bSrobbin# I can confirm that the Province of San Luis (and so far only that
3038593320bSrobbin# province) decided to go back to UTC-3 effective midnight Jan 20th 2008
3048593320bSrobbin# (that is, Monday 21st at 0:00 is the time the clocks were delayed back

3078593320bSrobbin#
3088593320bSrobbin# So we'll have to add yet another city to 'southamerica' (I think San

3128593320bSrobbin# (I only remember not being able to collect hard facts about San Luis
3138593320bSrobbin# back in 2004, when these provinces changed to UTC-4 for a few days, I

3593254abe6SNobutomo Nakano#
3603254abe6SNobutomo Nakano# The problem is that the changes in the rest of the Provinces that did

58880868c53Srobbin# From Paul Eggert (1993-11-18):
5897c478bd9Sstevel@tonic-gate# The mayor of Rio recently attempted to change the time zone rules
5907c478bd9Sstevel@tonic-gate# just in his city, in order to leave more summer time for the tourist trade.
5917c478bd9Sstevel@tonic-gate# The rule change lasted only part of the day;
5927c478bd9Sstevel@tonic-gate# the federal government refused to follow the city's rules, and business
5937c478bd9Sstevel@tonic-gate# was in a chaos, so the mayor backed down that afternoon.
5947c478bd9Sstevel@tonic-gate
5957c478bd9Sstevel@tonic-gate# From IATA SSIM (1996-02):
5967c478bd9Sstevel@tonic-gate# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
5976f8e8937SDan McDonald# Santa Catarina (SC), Paraná (PR), São Paulo (SP), Rio de Janeiro (RJ),
5986f8e8937SDan McDonald# Espírito Santo (ES), Minas Gerais (MG), Bahia (BA), Goiás (GO),
5997c478bd9Sstevel@tonic-gate# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
6007c478bd9Sstevel@tonic-gate# [The last three states are new to this issue of the IATA SSIM.]
6017c478bd9Sstevel@tonic-gate
6027c478bd9Sstevel@tonic-gate# From Gwillim Law (1996-10-07):
6036f8e8937SDan McDonald# Geography, history (Tocantins was part of Goiás until 1989), and other
6047c478bd9Sstevel@tonic-gate# sources of time zone information lead me to believe that AL, SE, and TO were
6057c478bd9Sstevel@tonic-gate# always in BR1, and so the only change was whether or not they observed DST....
6067c478bd9Sstevel@tonic-gate# The earliest issue of the SSIM I have is 2/91.  Each issue from then until
6077c478bd9Sstevel@tonic-gate# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
6087c478bd9Sstevel@tonic-gate# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
6097c478bd9Sstevel@tonic-gate# (UTC-4)....  The other two time zones given for Brazil are BR3, which is
6107c478bd9Sstevel@tonic-gate# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
6117c478bd9Sstevel@tonic-gate# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
6127c478bd9Sstevel@tonic-gate# become part of the state of Pernambuco).  The boundary between BR1 and BR2
6137c478bd9Sstevel@tonic-gate# has never been clearly stated.  They've simply been called East and West.
6147c478bd9Sstevel@tonic-gate# However, some conclusions can be drawn from another IATA manual: the Airline
6157c478bd9Sstevel@tonic-gate# Coding Directory, which lists close to 400 airports in Brazil.  For each
6167c478bd9Sstevel@tonic-gate# airport it gives a time zone which is coded to the SSIM.  From that
6176f8e8937SDan McDonald# information, I'm led to conclude that the states of Amapá (AP), Ceará (CE),
6186f8e8937SDan McDonald# Maranhão (MA), Paraíba (PR), Pernambuco (PE), Piauí (PI), and Rio Grande do
6196f8e8937SDan McDonald# Norte (RN), and the eastern part of Pará (PA) are all in BR1 without DST.

6307c478bd9Sstevel@tonic-gate# The reason for the delay this year has to do with elections in Brazil.
6317c478bd9Sstevel@tonic-gate#
6327c478bd9Sstevel@tonic-gate# Unlike in the United States, elections in Brazil are 100% computerized and
6337c478bd9Sstevel@tonic-gate# the results are known almost immediately.  Yesterday, it was the first
6347c478bd9Sstevel@tonic-gate# round of the elections when 115 million Brazilians voted for President,
6357c478bd9Sstevel@tonic-gate# Governor, Senators, Federal Deputies, and State Deputies.  Nobody is
6367c478bd9Sstevel@tonic-gate# counting (or re-counting) votes anymore and we know there will be a second
6377c478bd9Sstevel@tonic-gate# round for the Presidency and also for some Governors.  The 2nd round will
6387c478bd9Sstevel@tonic-gate# take place on October 27th.
6397c478bd9Sstevel@tonic-gate#
6407c478bd9Sstevel@tonic-gate# The reason why the DST will only begin November 3rd is that the thousands
6417c478bd9Sstevel@tonic-gate# of electoral machines used cannot have their time changed, and since the
6427c478bd9Sstevel@tonic-gate# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
6437c478bd9Sstevel@tonic-gate# the Government decided to postpone DST, instead of changing the Constitution
6447c478bd9Sstevel@tonic-gate# (maybe, for the next elections, it will be possible to change the clock)...
6457c478bd9Sstevel@tonic-gate
6467c478bd9Sstevel@tonic-gate# From Rodrigo Severo (2004-10-04):
6477c478bd9Sstevel@tonic-gate# It's just the biannual change made necessary by the much hyped, supposedly
6487c478bd9Sstevel@tonic-gate# modern Brazilian eletronic voting machines which, apparently, can't deal
6497c478bd9Sstevel@tonic-gate# with a time change between the first and the second rounds of the elections.

65556725381Srobbin# From Paul Schulze (2008-06-24):

6576f8e8937SDan McDonald# Oficial da União"...) in Brazil there are changes in the timezones,
65856725381Srobbin# effective today (00:00am at June 24, 2008) as follows:
65956725381Srobbin#
6606f8e8937SDan McDonald# a) The timezone UTC+5 is extinguished, with all the Acre state and the
66156725381Srobbin# part of the Amazonas state that had this timezone now being put to the
66256725381Srobbin# timezone UTC+4
6636f8e8937SDan McDonald# b) The whole Pará state now is put at timezone UTC+3, instead of just
66456725381Srobbin# part of it, as was before.
66556725381Srobbin#
66656725381Srobbin# This change follows a proposal of senator Tiao Viana of Acre state, that
66756725381Srobbin# proposed it due to concerns about open television channels displaying
66856725381Srobbin# programs inappropriate to youths in the states that had the timezone
66956725381Srobbin# UTC+5 too early in the night. In the occasion, some more corrections
67056725381Srobbin# were proposed, trying to unify the timezones of any given state. This
67156725381Srobbin# change modifies timezone rules defined in decree 2.784 of 18 June,
67256725381Srobbin# 1913.

67756725381Srobbin#
67856725381Srobbin# As a result of the above Decree I believe the America/Rio_Branco
67956725381Srobbin# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
6806f8e8937SDan McDonald# be created to represent the...west side of the Pará State. I
68156725381Srobbin# suggest this new timezone be called Santarem as the most

68356725381Srobbin#
68456725381Srobbin# This new timezone would be the same as the Rio_Branco timezone up to
68556725381Srobbin# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

14277c478bd9Sstevel@tonic-gate#
14287c478bd9Sstevel@tonic-gate# I have communicated several times with people there, and the last
14297c478bd9Sstevel@tonic-gate# time I had communications that was helpful was in 1998.  Here is
14307c478bd9Sstevel@tonic-gate# what was said then:
14317c478bd9Sstevel@tonic-gate#
14327c478bd9Sstevel@tonic-gate# "The general rule was that Stanley used daylight saving and the Camp
14337c478bd9Sstevel@tonic-gate# did not. However for various reasons many people in the Camp have
14347c478bd9Sstevel@tonic-gate# started to use daylight saving (known locally as 'Stanley Time')
14357c478bd9Sstevel@tonic-gate# There is no rule as to who uses daylight saving - it is a matter of
14367c478bd9Sstevel@tonic-gate# personal choice and so it is impossible to draw a map showing who
14377c478bd9Sstevel@tonic-gate# uses it and who does not. Any list would be out of date as soon as
14387c478bd9Sstevel@tonic-gate# it was produced. This year daylight saving ended on April 18/19th
14397c478bd9Sstevel@tonic-gate# and started again on September 12/13th.  I do not know what the rule
14407c478bd9Sstevel@tonic-gate# is, but can find out if you like.  We do not change at the same time
14417c478bd9Sstevel@tonic-gate# as UK or Chile."
14427c478bd9Sstevel@tonic-gate#
14437c478bd9Sstevel@tonic-gate# I did have in my notes that the rule was "Second Saturday in Sep at
14447c478bd9Sstevel@tonic-gate# 0:00 until third Saturday in Apr at 0:00".  I think that this does
14457c478bd9Sstevel@tonic-gate# not agree in some cases with Shanks; is this true?
14467c478bd9Sstevel@tonic-gate#
14477c478bd9Sstevel@tonic-gate# Also, there is no mention in the list that some areas in the
14487c478bd9Sstevel@tonic-gate# Falklands do not use DST.  I have found in my communications there
14497c478bd9Sstevel@tonic-gate# that these areas are on the western half of East Falkland and all of
14507c478bd9Sstevel@tonic-gate# West Falkland.  Stanley is the only place that consistently observes
14517c478bd9Sstevel@tonic-gate# DST.  Again, as in other places in the world, the farmers don't like
14527c478bd9Sstevel@tonic-gate# it.  West Falkland is almost entirely sheep farmers.
14537c478bd9Sstevel@tonic-gate#
14547c478bd9Sstevel@tonic-gate# I know one lady there that keeps a list of which farm keeps DST and
14557c478bd9Sstevel@tonic-gate# which doesn't each year.  She runs a shop in Stanley, and says that
14567c478bd9Sstevel@tonic-gate# the list changes each year.  She uses it to communicate to her
