  31 # From Paul Eggert (2006-03-22):
  32 # A good source for time zone historical data outside the U.S. is
  33 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
  34 # San Diego: ACS Publications, Inc. (2003).
  35 #
  36 # Gwillim Law writes that a good source
  37 # for recent time zone data is the International Air Transport
  38 # Association's Standard Schedules Information Manual (IATA SSIM),
  39 # published semiannually.  Law sent in several helpful summaries
  40 # of the IATA's data after 1990.
  41 #
  42 # Except where otherwise noted, Shanks & Pottenger is the source for
  43 # entries through 1990, and IATA SSIM is the source for entries afterwards.

 217 # Hora de verano para la Republica Argentina (2003-06-08)

 220 # over Shanks & Pottenger.

 222 # From Mariano Absatz (2004-06-05):
 223 # These media articles from a major newspaper mostly cover the current state:
 224 # http://www.lanacion.com.ar/04/05/27/de_604825.asp
 225 # http://www.lanacion.com.ar/04/05/28/de_605203.asp


 321 # (that is, Monday 21st at 0:00 is the time the clocks were delayed back
 322 # 1 hour), and they intend to keep UTC-3 as their timezone all year round
 323 # (that is, unless they change their mind any minute now).
 324 #
 325 # So we'll have to add yet another city to 'southamerica' (I think San
 326 # Luis city is the mos populated city in the Province, so it'd be
 327 # America/Argentina/San_Luis... of course I can't remember if San Luis's
 328 # history of particular changes goes along with Mendoza or San Juan :-(
 329 # (I only remember not being able to collect hard facts about San Luis
 330 # back in 2004, when these provinces changed to UTC-4 for a few days, I
 331 # mailed them personally and never got an answer).
 332 
 333 # From Paul Eggert (2008-06-30):
 334 # Unless otherwise specified, data are from Shanks & Pottenger through 1992,
 335 # from the IATA otherwise.  As noted below, Shanks & Pottenger say that
 336 # America/Cordoba split into 6 subregions during 1991/1992, one of which
 337 # was America/San_Luis, but we haven't verified this yet so for now we'll
 338 # keep America/Cordoba a single region rather than splitting it into the
 339 # other 5 subregions.

 511 # From Paul Eggert (1993-11-18):
 512 # The mayor of Rio recently attempted to change the time zone rules
 513 # just in his city, in order to leave more summer time for the tourist trade.
 514 # The rule change lasted only part of the day;


 581 # ...by law number 11.662 of April 24, 2008 (published in the "Diario
 582 # Oficial da Uniao"...) in Brazil there are changes in the timezones,
 583 # effective today (00:00am at June 24, 2008) as follows:
 584 #
 585 # a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
 586 # part of the Amazonas state that had this timezone now being put to the
 587 # timezone UTC+4
 588 # b) The whole Para state now is put at timezone UTC+3, instead of just
 589 # part of it, as was before.
 590 #
 591 # This change follows a proposal of senator Tiao Viana of Acre state, that
 592 # proposed it due to concerns about open television channels displaying
 593 # programs inappropriate to youths in the states that had the timezone
 594 # UTC+5 too early in the night. In the occasion, some more corrections
 595 # were proposed, trying to unify the timezones of any given state. This
 596 # change modifies timezone rules defined in decree 2.784 of 18 June,
 597 # 1913.
 598 
 599 # From Rodrigo Severo (2008-06-24):

 603 # </a>
 604 #
 605 # As a result of the above Decree I believe the America/Rio_Branco
 606 # timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
 607 # be created to represent the the west side of the Para State. I
 608 # suggest this new timezone be called Santarem as the most
 609 # important/populated city in the affected area.
 610 #
 611 # This new timezone would be the same as the Rio_Branco timezone up to
 612 # the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

 620 # - 4 time zones replaced by 3 time zones-eliminating time zone UTC- 05
 621 # (state Acre and the part of the Amazonas will be UTC/GMT- 04) - western
 622 # part of Par state is moving to one timezone UTC- 03 (from UTC -04).

 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

 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".

 654 # From Paul Eggert (1993-11-18):
 655 # The mayor of Rio recently attempted to change the time zone rules
 656 # just in his city, in order to leave more summer time for the tourist trade.
 657 # The rule change lasted only part of the day;


 724 # ...by law number 11.662 of April 24, 2008 (published in the "Diario
 725 # Oficial da Uniao"...) in Brazil there are changes in the timezones,
 726 # effective today (00:00am at June 24, 2008) as follows:
 727 #
 728 # a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
 729 # part of the Amazonas state that had this timezone now being put to the
 730 # timezone UTC+4
 731 # b) The whole Para state now is put at timezone UTC+3, instead of just
 732 # part of it, as was before.
 733 #
 734 # This change follows a proposal of senator Tiao Viana of Acre state, that
 735 # proposed it due to concerns about open television channels displaying
 736 # programs inappropriate to youths in the states that had the timezone
 737 # UTC+5 too early in the night. In the occasion, some more corrections
 738 # were proposed, trying to unify the timezones of any given state. This
 739 # change modifies timezone rules defined in decree 2.784 of 18 June,
 740 # 1913.
 741 
 742 # From Rodrigo Severo (2008-06-24):
 743 # Just correcting the URL:

 746 # </a>
 747 #
 748 # As a result of the above Decree I believe the America/Rio_Branco
 749 # timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
 750 # be created to represent the the west side of the Para State. I
 751 # suggest this new timezone be called Santarem as the most
 752 # important/populated city in the affected area.
 753 #
 754 # This new timezone would be the same as the Rio_Branco timezone up to
 755 # the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

 762 #
 763 # - 4 time zones replaced by 3 time zones-eliminating time zone UTC- 05
 764 # (state Acre and the part of the Amazonas will be UTC/GMT- 04) - western
 765 # part of Par state is moving to one timezone UTC- 03 (from UTC -04).
