    30 # From Paul Eggert (2006-03-22):
       
    31 # A good source for time zone historical data outside the U.S. is
       
    32 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
       
    33 # San Diego: ACS Publications, Inc. (2003).
       
    34 #
       
    35 # Gwillim Law writes that a good source
       
    36 # for recent time zone data is the International Air Transport
       
    37 # Association's Standard Schedules Information Manual (IATA SSIM),
       
    38 # published semiannually.  Law sent in several helpful summaries
       
    39 # of the IATA's data after 1990.
       
    40 #
       
    41 # Except where otherwise noted, Shanks & Pottenger is the source for
       
    42 # entries through 1990, and IATA SSIM is the source for entries afterwards.
       
    43 #
       
    44 # Earlier editions of these tables used the North American style (e.g. ARST and
       
    45 # ARDT for Argentine Standard and Daylight Time), but the following quote
       
    46 # suggests that it's better to use European style (e.g. ART and ARST).
       
    47 #	I suggest the use of _Summer time_ instead of the more cumbersome
       
    48 #	_daylight-saving time_.  _Summer time_ seems to be in general use
       
    49 #	in Europe and South America.
       
    50 #	-- E O Cutler, _New York Times_ (1937-02-14), quoted in

    52 #
       
    53 # Earlier editions of these tables also used the North American style
       
    54 # for time zones in Brazil, but this was incorrect, as Brazilians say
       
    55 # "summer time".  Reinaldo Goulart, a Sao Paulo businessman active in
       
    56 # the railroad sector, writes (1999-07-06):
       
    57 #	The subject of time zones is currently a matter of discussion/debate in
       
    58 #	Brazil.  Let's say that "the Brasilia time" is considered the
       
    59 #	"official time" because Brasilia is the capital city.
       
    60 #	The other three time zones are called "Brasilia time "minus one" or
       
    61 #	"plus one" or "plus two".  As far as I know there is no such
       
    62 #	name/designation as "Eastern Time" or "Central Time".
       
    63 # So I invented the following (English-language) abbreviations for now.

   384 # From Paul Eggert (1993-11-18):
       
   385 # The mayor of Rio recently attempted to change the time zone rules
       
   386 # just in his city, in order to leave more summer time for the tourist trade.
       
   387 # The rule change lasted only part of the day;
       
   388 # the federal government refused to follow the city's rules, and business
       
   389 # was in a chaos, so the mayor backed down that afternoon.
       
   390 
       
   391 # From IATA SSIM (1996-02):
       
   392 # _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
       
   393 # Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
       
   394 # Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
       
   395 # Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
       
   396 # [The last three states are new to this issue of the IATA SSIM.]
       
   397 
       
   398 # From Gwillim Law (1996-10-07):
       
   399 # Geography, history (Tocantins was part of Goias until 1989), and other
       
   400 # sources of time zone information lead me to believe that AL, SE, and TO were
       
   401 # always in BR1, and so the only change was whether or not they observed DST....
       
   402 # The earliest issue of the SSIM I have is 2/91.  Each issue from then until
       
   403 # 9/95 says that DST is observed only in the ten states I quoted from 9/95,
       
   404 # along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
       
   405 # (UTC-4)....  The other two time zones given for Brazil are BR3, which is
       
   406 # UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
       
   407 # UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
       
   408 # become part of the state of Pernambuco).  The boundary between BR1 and BR2
       
   409 # has never been clearly stated.  They've simply been called East and West.
       
   410 # However, some conclusions can be drawn from another IATA manual: the Airline
       
   411 # Coding Directory, which lists close to 400 airports in Brazil.  For each
       
   412 # airport it gives a time zone which is coded to the SSIM.  From that
       
   413 # information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
       
   414 # Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
       
   415 # Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.

   427 # From Celso Doria via David Madeo (2002-10-09):
       
   428 # The reason for the delay this year has to do with elections in Brazil.
       
   429 #
       
   430 # Unlike in the United States, elections in Brazil are 100% computerized and
       
   431 # the results are known almost immediately.  Yesterday, it was the first
       
   432 # round of the elections when 115 million Brazilians voted for President,
       
   433 # Governor, Senators, Federal Deputies, and State Deputies.  Nobody is
       
   434 # counting (or re-counting) votes anymore and we know there will be a second
       
   435 # round for the Presidency and also for some Governors.  The 2nd round will
       
   436 # take place on October 27th.
       
   437 #
       
   438 # The reason why the DST will only begin November 3rd is that the thousands
       
   439 # of electoral machines used cannot have their time changed, and since the
       
   440 # Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
       
   441 # the Government decided to postpone DST, instead of changing the Constitution
       
   442 # (maybe, for the next elections, it will be possible to change the clock)...
       
   443 
       
   444 # From Rodrigo Severo (2004-10-04):
       
   445 # It's just the biannual change made necessary by the much hyped, supposedly
       
   446 # modern Brazilian eletronic voting machines which, apparently, can't deal
       
   447 # with a time change between the first and the second rounds of the elections.

   872 # time I had communications that was helpful was in 1998.  Here is
       
   873 # what was said then:
       
   874 #
       
   875 # "The general rule was that Stanley used daylight saving and the Camp
       
   876 # did not. However for various reasons many people in the Camp have
       
   877 # started to use daylight saving (known locally as 'Stanley Time')
       
   878 # There is no rule as to who uses daylight saving - it is a matter of
       
   879 # personal choice and so it is impossible to draw a map showing who
       
   880 # uses it and who does not. Any list would be out of date as soon as
       
   881 # it was produced. This year daylight saving ended on April 18/19th
       
   882 # and started again on September 12/13th.  I do not know what the rule
       
   883 # is, but can find out if you like.  We do not change at the same time
       
   884 # as UK or Chile."
       
   885 #
       
   886 # I did have in my notes that the rule was "Second Saturday in Sep at
       
   887 # 0:00 until third Saturday in Apr at 0:00".  I think that this does
       
   888 # not agree in some cases with Shanks; is this true?
       
   889 #
       
   890 # Also, there is no mention in the list that some areas in the
       
   891 # Falklands do not use DST.  I have found in my communications there
       
   892 # that these areas are on the western half of East Falkland and all of
       
   893 # West Falkland.  Stanley is the only place that consistently observes
       
   894 # DST.  Again, as in other places in the world, the farmers don't like
       
   895 # it.  West Falkland is almost entirely sheep farmers.
       
   896 #
       
   897 # I know one lady there that keeps a list of which farm keeps DST and
       
   898 # which doesn't each year.  She runs a shop in Stanley, and says that
