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

143 # From Fabian L. Arce Jofre (2000-04-04):
144 # The law that claimed DST for Argentina was derogated by President Fernando

146 # in the winter time, rather than less. The change took effect on March 3.

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

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

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

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

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

461
462 # From Alexander Krivenyshev (2010-04-09):

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

716
717 # From Celso Doria via David Madeo (2002-10-09):
718 # The reason for the delay this year has to do with elections in Brazil.
719 #
720 # Unlike in the United States, elections in Brazil are 100% computerized and
721 # the results are known almost immediately. Yesterday, it was the first
722 # round of the elections when 115 million Brazilians voted for President,
723 # Governor, Senators, Federal Deputies, and State Deputies. Nobody is
724 # counting (or re-counting) votes anymore and we know there will be a second
725 # round for the Presidency and also for some Governors. The 2nd round will
726 # take place on October 27th.
727 #
728 # The reason why the DST will only begin November 3rd is that the thousands
729 # of electoral machines used cannot have their time changed, and since the
730 # Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
731 # the Government decided to postpone DST, instead of changing the Constitution
732 # (maybe, for the next elections, it will be possible to change the clock)...
733
734 # From Rodrigo Severo (2004-10-04):
735 # It's just the biannual change made necessary by the much hyped, supposedly
736 # modern Brazilian eletronic voting machines which, apparently, can't deal
737 # with a time change between the first and the second rounds of the elections.
738
739 # From Steffen Thorsen (2007-09-20):
740 # Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00:

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

768 # As a result of the above Decree I believe the America/Rio_Branco
769 # timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
770 # be created to represent the...west side of the Para State. I

773 #
774 # This new timezone would be the same as the Rio_Branco timezone up to

1164 # of October.... The law is the same for March and October.
1165 # (1998-09-29):
1166 # Because of the drought this year, the government decided to go into
1167 # DST earlier (saturday 9/26 at 24:00). This is a one-time change only ...

1169

1255 # As stated in the website of the Chilean Energy Ministry
1256 # http://www.minenergia.cl/ministerio/noticias/generales/gobierno-anuncia-fechas-de-cambio-de.html
1257 # The Chilean Government has decided to postpone the entrance into winter time
1258 # (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
1259 # been yet formalized but it will within the next days.
1260 # Quote from the website communication:
1261 #
1262 # 6. For the year 2012, the dates of entry into winter time will be as follows:
1263 # a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
1264 # 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
1265 # of the same day.
1266 # b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
1267 # at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
1268 # 01:00 on September 2.

1414 # "The general rule was that Stanley used daylight saving and the Camp
1415 # did not. However for various reasons many people in the Camp have
1416 # started to use daylight saving (known locally as 'Stanley Time')
1417 # There is no rule as to who uses daylight saving - it is a matter of
1418 # personal choice and so it is impossible to draw a map showing who
1419 # uses it and who does not. Any list would be out of date as soon as
1420 # it was produced. This year daylight saving ended on April 18/19th
1421 # and started again on September 12/13th. I do not know what the rule
1422 # is, but can find out if you like. We do not change at the same time
1423 # as UK or Chile."
1424 #
1425 # I did have in my notes that the rule was "Second Saturday in Sep at
1426 # 0:00 until third Saturday in Apr at 0:00". I think that this does
1427 # not agree in some cases with Shanks; is this true?
1428 #
1429 # Also, there is no mention in the list that some areas in the
1430 # Falklands do not use DST. I have found in my communications there
1431 # that these areas are on the western half of East Falkland and all of
1432 # West Falkland. Stanley is the only place that consistently observes
1433 # DST. Again, as in other places in the world, the farmers don't like
1434 # it. West Falkland is almost entirely sheep farmers.
1435 #
1436 # I know one lady there that keeps a list of which farm keeps DST and
1437 # which doesn't each year. She runs a shop in Stanley, and says that
1438 # the list changes each year. She uses it to communicate to her
1439 # customers, catching them when they are home for lunch or dinner.
1440
1441 # From Paul Eggert (2001-03-05):
1442 # For now, we'll just record the time in Stanley, since we have no
1443 # better info.
1444
1445 # From Steffen Thorsen (2011-04-01):
1446 # The Falkland Islands will not turn back clocks this winter, but stay on
1447 # daylight saving time.

1454 # We have gotten this confirmed by a clerk of the legislative assembly:
1455 # Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the
1456 # third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3
1457 # hours) on the first Sunday of September at 0200hrs.
1458 #
1459 # IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands
1460 # will not revert to local mean time, but clocks will remain on Summer
1461 # time (UTC/GMT - 3 hours) throughout the whole of 2011. Any long term
1462 # change to local time following the trial period will be notified.

1466 # Cable & Wireless Falkland Islands (dated 2012-02-22)
1467 # states...
1468 # The current Atlantic/Stanley entry under South America expects the
1469 # clocks to go back to standard Falklands Time (FKT) on the 15th April.
1470 # The database entry states that in 2011 Stanley was staying on fixed
1471 # summer time on a trial basis only. FIG need to contact IANA and/or
1472 # the maintainers of the database to inform them we're adopting
1473 # the same policy this year and suggest recommendations for future years.
1474 #
1475 # For now we will assume permanent summer time for the Falklands

1477 # experiment was apparently successful.)
