33 # From Paul Eggert (2006-03-22):
34 # A good source for time zone historical data outside the U.S. is
35 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
36 # San Diego: ACS Publications, Inc. (2003).
37 #
38 # Gwillim Law writes that a good source
39 # for recent time zone data is the International Air Transport
40 # Association's Standard Schedules Information Manual (IATA SSIM),
41 # published semiannually. Law sent in several helpful summaries
42 # of the IATA's data after 1990.
43 #
44 # Except where otherwise noted, Shanks & Pottenger is the source for
45 # entries through 1990, and IATA SSIM is the source for entries afterwards.
46 #
47 # Earlier editions of these tables used the North American style (e.g. ARST and
48 # ARDT for Argentine Standard and Daylight Time), but the following quote
49 # suggests that it's better to use European style (e.g. ART and ARST).
50 # I suggest the use of _Summer time_ instead of the more cumbersome
51 # _daylight-saving time_. _Summer time_ seems to be in general use
52 # in Europe and South America.
53 # -- E O Cutler, _New York Times_ (1937-02-14), quoted in
54 # H L Mencken, _The American Language: Supplement I_ (1960), p 466
55 #
56 # Earlier editions of these tables also used the North American style
57 # for time zones in Brazil, but this was incorrect, as Brazilians say
58 # "summer time". Reinaldo Goulart, a Sao Paulo businessman active in
59 # the railroad sector, writes (1999-07-06):
60 # The subject of time zones is currently a matter of discussion/debate in
61 # Brazil. Let's say that "the Brasilia time" is considered the
62 # "official time" because Brasilia is the capital city.
63 # The other three time zones are called "Brasilia time "minus one" or
64 # "plus one" or "plus two". As far as I know there is no such
65 # name/designation as "Eastern Time" or "Central Time".
66 # So I invented the following (English-language) abbreviations for now.

142 # So Buenos Aires should be -3 hours from GMT at all times.
143 #
144 # From Fabian L. Arce Jofre (2000-04-04):
145 # The law that claimed DST for Argentina was derogated by President Fernando
146 # de la Rua on March 2, 2000, because it would make people spend more energy
147 # in the winter time, rather than less. The change took effect on March 3.

172 # From Steffen Thorsen (2007-12-21):

294 # "The time change in Tierra del Fuego was a conflicted decision from

298 # Our understanding was that the change was originally scheduled to take place
299 # on June 1 at 00:00 in Chubut, Santa Cruz, Tierra del Fuego (and some other

377 # So we'll have to add yet another city to 'southamerica' (I think San
378 # Luis city is the mos populated city in the Province, so it'd be
379 # America/Argentina/San_Luis... of course I can't remember if San Luis's
380 # history of particular changes goes along with Mendoza or San Juan :-(
381 # (I only remember not being able to collect hard facts about San Luis
382 # back in 2004, when these provinces changed to UTC-4 for a few days, I
383 # mailed them personally and never got an answer).

385 # From Paul Eggert (2008-06-30):
386 # Unless otherwise specified, data are from Shanks & Pottenger through 1992,
387 # from the IATA otherwise. As noted below, Shanks & Pottenger say that
388 # America/Cordoba split into 6 subregions during 1991/1992, one of which
389 # was America/San_Luis, but we haven't verified this yet so for now we'll
390 # keep America/Cordoba a single region rather than splitting it into the
391 # other 5 subregions.
392
393 # From Mariano Absatz (2009-03-13):
394 # Yesterday (with our usual 2-day notice) the Province of San Luis
395 # decided that next Sunday instead of "staying" @utc-03:00 they will go
396 # to utc-04:00 until the second Saturday in October...

413 # The press release says:
414 # (...) anunció que el próximo domingo a las 00:00 los puntanos deberán
415 # atrasar una hora sus relojes.
416 #
417 # A partir de entonces, San Luis establecerá el huso horario propio de
418 # la Provincia. De esta manera, durante el periodo del calendario anual
419 # 2009, el cambio horario quedará comprendido entre las 00:00 del tercer
420 # domingo de marzo y las 24:00 del segundo sábado de octubre.
421 # Quick&dirty translation
422 # (...) announced that next Sunday, at 00:00, Puntanos (the San Luis
423 # inhabitants) will have to turn back one hour their clocks
424 #
425 # Since then, San Luis will establish its own Province timezone. Thus,
426 # during 2009, this timezone change will run from 00:00 the third Sunday
427 # in March until 24:00 of the second Saturday in October.
428
429 # From Mariano Absatz (2009-10-16):

436 # is ambiguous because establishes a calendar from the 2nd Sunday in
437 # October at 0:00 thru the 2nd Saturday in March at 24:00 and the
438 # complement of that starting on the 2nd Sunday of March at 0:00 and
439 # ending on the 2nd Saturday of March at 24:00.
440 #
441 # This clearly breaks every time the 1st of March or October is a Sunday.
442 #
443 # IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
444 # Sunday of October and March.
445 #
446 # The problem is that the changes in the rest of the Provinces that did
447 # change in 2007/2008, were made according to the Federal Law and Decrees
448 # that did so on the 3rd Sunday of October and March.
449 #
450 # In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
451 # (October 11th) at 0:00.
452 #
453 # So I guess a new set of rules, besides "Arg", must be made and the last
454 # America/Argentina/San_Luis entries should change to use these...
455 #
456 # I'm enclosing a patch that does what I say... regretfully, the San Luis
457 # timezone must be called "WART/WARST" even when most of the time (like,
458 # right now) WARST == ART... that is, since last Sunday, all the country
459 # is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
460 # of the country calls it "ART".

462
463 # From Alexander Krivenyshev (2010-04-09):
464 # According to news reports from El Diario de la Republica Province San

675 # From Paul Eggert (1993-11-18):
676 # The mayor of Rio recently attempted to change the time zone rules
677 # just in his city, in order to leave more summer time for the tourist trade.
678 # The rule change lasted only part of the day;
679 # the federal government refused to follow the city's rules, and business
680 # was in a chaos, so the mayor backed down that afternoon.
681
682 # From IATA SSIM (1996-02):
683 # _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
684 # Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
685 # Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
686 # Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
687 # [The last three states are new to this issue of the IATA SSIM.]
688
689 # From Gwillim Law (1996-10-07):
690 # Geography, history (Tocantins was part of Goias until 1989), and other
691 # sources of time zone information lead me to believe that AL, SE, and TO were
692 # always in BR1, and so the only change was whether or not they observed DST....
693 # The earliest issue of the SSIM I have is 2/91. Each issue from then until
694 # 9/95 says that DST is observed only in the ten states I quoted from 9/95,
695 # along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
696 # (UTC-4).... The other two time zones given for Brazil are BR3, which is
697 # UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
698 # UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
699 # become part of the state of Pernambuco). The boundary between BR1 and BR2
700 # has never been clearly stated. They've simply been called East and West.
701 # However, some conclusions can be drawn from another IATA manual: the Airline
702 # Coding Directory, which lists close to 400 airports in Brazil. For each
703 # airport it gives a time zone which is coded to the SSIM. From that
704 # information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
705 # Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
706 # Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.

717
718 # From Celso Doria via David Madeo (2002-10-09):
719 # The reason for the delay this year has to do with elections in Brazil.
720 #
721 # Unlike in the United States, elections in Brazil are 100% computerized and
722 # the results are known almost immediately. Yesterday, it was the first
723 # round of the elections when 115 million Brazilians voted for President,
724 # Governor, Senators, Federal Deputies, and State Deputies. Nobody is
725 # counting (or re-counting) votes anymore and we know there will be a second
726 # round for the Presidency and also for some Governors. The 2nd round will
727 # take place on October 27th.
728 #
729 # The reason why the DST will only begin November 3rd is that the thousands
730 # of electoral machines used cannot have their time changed, and since the
731 # Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
732 # the Government decided to postpone DST, instead of changing the Constitution
733 # (maybe, for the next elections, it will be possible to change the clock)...
734
735 # From Rodrigo Severo (2004-10-04):
736 # It's just the biannual change made necessary by the much hyped, supposedly
737 # modern Brazilian eletronic voting machines which, apparently, can't deal
738 # with a time change between the first and the second rounds of the elections.
739
740 # From Steffen Thorsen (2007-09-20):
741 # Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00:

744 # From Paul Schulze (2008-06-24):
745 # ...by law number 11.662 of April 24, 2008 (published in the "Diario
746 # Oficial da Uniao"...) in Brazil there are changes in the timezones,
747 # effective today (00:00am at June 24, 2008) as follows:
748 #
749 # a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
750 # part of the Amazonas state that had this timezone now being put to the
751 # timezone UTC+4
752 # b) The whole Para state now is put at timezone UTC+3, instead of just
753 # part of it, as was before.
754 #
755 # This change follows a proposal of senator Tiao Viana of Acre state, that
756 # proposed it due to concerns about open television channels displaying
757 # programs inappropriate to youths in the states that had the timezone
758 # UTC+5 too early in the night. In the occasion, some more corrections
759 # were proposed, trying to unify the timezones of any given state. This
760 # change modifies timezone rules defined in decree 2.784 of 18 June,
761 # 1913.

769 # As a result of the above Decree I believe the America/Rio_Branco
770 # timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
771 # be created to represent the...west side of the Para State. I
772 # suggest this new timezone be called Santarem as the most
773 # important/populated city in the affected area.
774 #
775 # This new timezone would be the same as the Rio_Branco timezone up to
776 # the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

1154 # of October.... The law is the same for March and October.
1155 # (1998-09-29):
1156 # Because of the drought this year, the government decided to go into
1157 # DST earlier (saturday 9/26 at 24:00). This is a one-time change only ...

1159
1160 # From Julio I. Pacheco Troncoso (1999-03-18):

1245 # As stated in the website of the Chilean Energy Ministry
1246 # http://www.minenergia.cl/ministerio/noticias/generales/gobierno-anuncia-fechas-de-cambio-de.html
1247 # The Chilean Government has decided to postpone the entrance into winter time
1248 # (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
1249 # been yet formalized but it will within the next days.
1250 # Quote from the website communication:
1251 #
1252 # 6. For the year 2012, the dates of entry into winter time will be as follows:
1253 # a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
1254 # 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
1255 # of the same day.
1256 # b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
1257 # at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
1258 # 01:00 on September 2.

1403 #
1404 # "The general rule was that Stanley used daylight saving and the Camp

1406 # started to use daylight saving (known locally as 'Stanley Time')
1407 # There is no rule as to who uses daylight saving - it is a matter of
1408 # personal choice and so it is impossible to draw a map showing who
1409 # uses it and who does not. Any list would be out of date as soon as
1410 # it was produced. This year daylight saving ended on April 18/19th
1411 # and started again on September 12/13th. I do not know what the rule

1415 # I did have in my notes that the rule was "Second Saturday in Sep at
1416 # 0:00 until third Saturday in Apr at 0:00". I think that this does
1417 # not agree in some cases with Shanks; is this true?
1418 #
1419 # Also, there is no mention in the list that some areas in the
1420 # Falklands do not use DST. I have found in my communications there
1421 # that these areas are on the western half of East Falkland and all of
1422 # West Falkland. Stanley is the only place that consistently observes
1423 # DST. Again, as in other places in the world, the farmers don't like
1424 # it. West Falkland is almost entirely sheep farmers.
1425 #
1426 # I know one lady there that keeps a list of which farm keeps DST and
1427 # which doesn't each year. She runs a shop in Stanley, and says that
1428 # the list changes each year. She uses it to communicate to her
1429 # customers, catching them when they are home for lunch or dinner.

1450 # will not revert to local mean time, but clocks will remain on Summer

1458 # The current Atlantic/Stanley entry under South America expects the

1460 # The database entry states that in 2011 Stanley was staying on fixed
