223 # These media articles from a major newspaper mostly cover the current state:

225 # http://www.lanacion.com.ar/04/05/28/de_605203.asp

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

334 # Unless otherwise specified, data are from Shanks & Pottenger through 1992,

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

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):
600 # Just correcting the URL:

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.

619 #
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).

263 # From Paul Eggert (2004-05-24):

274 # From Mariano Absatz (2004-06-05):
275 # These media articles from a major newspaper mostly cover the current state:
276 # http://www.lanacion.com.ar/04/05/27/de_604825.asp
277 # http://www.lanacion.com.ar/04/05/28/de_605203.asp
373 # (that is, Monday 21st at 0:00 is the time the clocks were delayed back
374 # 1 hour), and they intend to keep UTC-3 as their timezone all year round
375 # (that is, unless they change their mind any minute now).
376 #
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).
384
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

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):
430 # ...the Province of San Luis is a case in itself.
431 #
432 # The Law at
433 # <a href="http://www.diputadossanluis.gov.ar/diputadosasp/paginas/verNorma.asp?NormaID=276>"
434 # http://www.diputadossanluis.gov.ar/diputadosasp/paginas/verNorma.asp?NormaID=276
435 # </a>
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".

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:
744 # <a href="https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008">
745 # https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008
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.
