323 # (that is, Monday 21st at 0:00 is the time the clocks were delayed back |
|
324 # 1 hour), and they intend to keep UTC-3 as their timezone all year round |
|
325 # (that is, unless they change their mind any minute now). |
|
326 # |
|
327 # So we'll have to add yet another city to 'southamerica' (I think San |
|
328 # Luis city is the mos populated city in the Province, so it'd be |
|
329 # America/Argentina/San_Luis... of course I can't remember if San Luis's |
|
330 # history of particular changes goes along with Mendoza or San Juan :-( |
|
331 # (I only remember not being able to collect hard facts about San Luis |
|
332 # back in 2004, when these provinces changed to UTC-4 for a few days, I |
|
333 # mailed them personally and never got an answer). |
|
334 |
|
335 # From Paul Eggert (2014-08-12): |
|
336 # Unless otherwise specified, data entries are from Shanks & Pottenger through |
|
337 # 1992, from the IATA otherwise. As noted below, Shanks & Pottenger say that |
|
338 # America/Cordoba split into 6 subregions during 1991/1992, one of which |
|
339 # was America/San_Luis, but we haven't verified this yet so for now we'll |
|
340 # keep America/Cordoba a single region rather than splitting it into the |
|
341 # other 5 subregions. |
|
342 |
|
343 # From Mariano Absatz (2009-03-13): |
|
344 # Yesterday (with our usual 2-day notice) the Province of San Luis |
|
345 # decided that next Sunday instead of "staying" @utc-03:00 they will go |
|
346 # to utc-04:00 until the second Saturday in October... |
|
347 # |
|
348 # The press release is at |
|
349 # http://www.sanluis.gov.ar/SL/Paginas/NoticiaDetalle.asp?TemaId=1&InfoPrensaId=3102 |
|
350 # (I couldn't find the decree, but www.sanluis.gov.ar |
|
351 # is the official page for the Province Government.) |
|
352 # |
|
353 # There's also a note in only one of the major national papers ... |
|
354 # http://www.lanacion.com.ar/nota.asp?nota_id=1107912 |
|
355 # |
|
356 # The press release says [quick and dirty translation]: |
|
357 # ... announced that next Sunday, at 00:00, Puntanos (the San Luis |
|
358 # inhabitants) will have to turn back one hour their clocks |
|
359 # |
|
360 # Since then, San Luis will establish its own Province timezone. Thus, |
|
361 # during 2009, this timezone change will run from 00:00 the third Sunday |
|
362 # in March until 24:00 of the second Saturday in October. |
|
363 |
|
364 # From Mariano Absatz (2009-10-16): |
|
365 # ...the Province of San Luis is a case in itself. |
|
366 # |
|
367 # The Law at |
|
368 # http://www.diputadossanluis.gov.ar/diputadosasp/paginas/verNorma.asp?NormaID=276 |
|
369 # is ambiguous because establishes a calendar from the 2nd Sunday in |
|
370 # October at 0:00 thru the 2nd Saturday in March at 24:00 and the |
|
371 # complement of that starting on the 2nd Sunday of March at 0:00 and |
|
372 # ending on the 2nd Saturday of March at 24:00. |
|
373 # |
|
374 # This clearly breaks every time the 1st of March or October is a Sunday. |
|
375 # |
|
376 # IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd |
|
377 # Sunday of October and March. |
|
378 # |
|
379 # The problem is that the changes in the rest of the Provinces that did |
|
380 # change in 2007/2008, were made according to the Federal Law and Decrees |
|
381 # that did so on the 3rd Sunday of October and March. |
|
382 # |
|
383 # In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday |
|
384 # (October 11th) at 0:00. |
|
385 # |
|
386 # So I guess a new set of rules, besides "Arg", must be made and the last |
|
387 # America/Argentina/San_Luis entries should change to use these... |
|
388 # ... |
|
389 |
|
390 # From Alexander Krivenyshev (2010-04-09): |
|
391 # According to news reports from El Diario de la República Province San |
|
392 # Luis, Argentina (standard time UTC-04) will keep Daylight Saving Time |
|
393 # after April 11, 2010 - will continue to have same time as rest of |

400 |
|
401 # From Mariano Absatz (2010-04-12): |
|
402 # yes...I can confirm this...and given that San Luis keeps calling |
|
403 # UTC-03:00 "summer time", we should't just let San Luis go back to "Arg" |
|
404 # rules...San Luis is still using "Western ARgentina Time" and it got |
|
405 # stuck on Summer daylight savings time even though the summer is over. |
|
406 |
|
407 # From Paul Eggert (2013-09-05): |
|
408 # Perhaps San Luis operates on the legal fiction that it is at -04 |
|
409 # with perpetual summer time, but ordinary usage typically seems to |
|
410 # just say it's at -03; see, for example, |
|
411 # http://es.wikipedia.org/wiki/Hora_oficial_argentina |
|
412 # We've documented similar situations as being plain changes to |
|
413 # standard time, so let's do that here too. This does not change UTC |
|
414 # offsets, only tm_isdst and the time zone abbreviations. One minor |
|
415 # plus is that this silences a zic complaint that there's no POSIX TZ |
|
416 # setting for time stamps past 2038. |

|
610 # From Paul Eggert (1993-11-18): |
|
611 # The mayor of Rio recently attempted to change the time zone rules |
|
612 # just in his city, in order to leave more summer time for the tourist trade. |
|
613 # The rule change lasted only part of the day; |
|
614 # the federal government refused to follow the city's rules, and business |
|
615 # was in a chaos, so the mayor backed down that afternoon. |
|
616 |
|
617 # From IATA SSIM (1996-02): |
|
618 # _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS), |
|
619 # Santa Catarina (SC), Paraná (PR), São Paulo (SP), Rio de Janeiro (RJ), |
|
620 # Espírito Santo (ES), Minas Gerais (MG), Bahia (BA), Goiás (GO), |
|
621 # Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL]. |
|
622 # [The last three states are new to this issue of the IATA SSIM.] |
|
623 |
|
624 # From Gwillim Law (1996-10-07): |
|
625 # Geography, history (Tocantins was part of Goiás until 1989), and other |
|
626 # sources of time zone information lead me to believe that AL, SE, and TO were |
|
627 # always in BR1, and so the only change was whether or not they observed DST.... |
|
628 # The earliest issue of the SSIM I have is 2/91. Each issue from then until |
|
629 # 9/95 says that DST is observed only in the ten states I quoted from 9/95, |
|
630 # along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2 |
|
631 # (UTC-4).... The other two time zones given for Brazil are BR3, which is |
|
632 # UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is |
|
633 # UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's |
|
634 # become part of the state of Pernambuco). The boundary between BR1 and BR2 |
|
635 # has never been clearly stated. They've simply been called East and West. |
|
636 # However, some conclusions can be drawn from another IATA manual: the Airline |
|
637 # Coding Directory, which lists close to 400 airports in Brazil. For each |
|
638 # airport it gives a time zone which is coded to the SSIM. From that |
|
639 # information, I'm led to conclude that the states of Amapá (AP), Ceará (CE), |
|

|
651 # From Celso Doria via David Madeo (2002-10-09): |
|
652 # The reason for the delay this year has to do with elections in Brazil. |
|
653 # |
|
654 # Unlike in the United States, elections in Brazil are 100% computerized and |
|
655 # the results are known almost immediately. Yesterday, it was the first |
|
656 # round of the elections when 115 million Brazilians voted for President, |
|
657 # Governor, Senators, Federal Deputies, and State Deputies. Nobody is |
|
658 # counting (or re-counting) votes anymore and we know there will be a second |
|
659 # round for the Presidency and also for some Governors. The 2nd round will |
|
660 # take place on October 27th. |
|
661 # |
|
662 # The reason why the DST will only begin November 3rd is that the thousands |
|
663 # of electoral machines used cannot have their time changed, and since the |
|
664 # Constitution says the elections must begin at 8:00 AM and end at 5:00 PM, |
|
665 # the Government decided to postpone DST, instead of changing the Constitution |
|
666 # (maybe, for the next elections, it will be possible to change the clock)... |
|
667 |
|
668 # From Rodrigo Severo (2004-10-04): |
|
669 # It's just the biannual change made necessary by the much hyped, supposedly |
|
670 # modern Brazilian eletronic voting machines which, apparently, can't deal |
|
671 # with a time change between the first and the second rounds of the elections. |
|
672 |
|
673 # From Steffen Thorsen (2007-09-20): |

676 |
|
677 # From Paul Schulze (2008-06-24): |
|
678 # ...by law number 11.662 of April 24, 2008 (published in the "Diario |
|
679 # Oficial da União"...) in Brazil there are changes in the timezones, |
|
680 # effective today (00:00am at June 24, 2008) as follows: |
|
681 # |
|
682 # a) The timezone UTC+5 is extinguished, with all the Acre state and the |
|
683 # part of the Amazonas state that had this timezone now being put to the |
|
684 # timezone UTC+4 |
|
685 # b) The whole Pará state now is put at timezone UTC+3, instead of just |
|
686 # part of it, as was before. |
|
687 # |
|
688 # This change follows a proposal of senator Tiao Viana of Acre state, that |
|
689 # proposed it due to concerns about open television channels displaying |
|
690 # programs inappropriate to youths in the states that had the timezone |
|
691 # UTC+5 too early in the night. In the occasion, some more corrections |
|
692 # were proposed, trying to unify the timezones of any given state. This |
|
693 # change modifies timezone rules defined in decree 2.784 of 18 June, |
|
694 # 1913. |

699 # |
|
700 # As a result of the above Decree I believe the America/Rio_Branco |
|
701 # timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall |
|
702 # be created to represent the...west side of the Pará State. I |
|
703 # suggest this new timezone be called Santarem as the most |
|
704 # important/populated city in the affected area. |
|
705 # |
|
706 # This new timezone would be the same as the Rio_Branco timezone up to |
|
707 # the 2008/06/24 change which would be to UTC-3 instead of UTC-4. |

|
725 # it will end on 2009-02-15 (current rule for Brazil is fine). Based on |

726 # past years experience with the elections, there was a good chance that |

1094 # 1890 and rounds its UTC offset to 70W40; guess that in practice this |
|
1095 # was the same offset as in 1916-1919. It also says Pacific/Easter |
|
1096 # standardized on 109W22 in 1890; assume this didn't change the clocks. |

1205 # Today appeared in the Diario Oficial a decree amending the time change |
|
1206 # dates to 2014. |
|
1207 # DST End: last Saturday of April 2014 (Sun 27 Apr 2014 03:00 UTC) |
|
1208 # DST Start: first Saturday of September 2014 (Sun 07 Sep 2014 04:00 UTC) |

|
1211 # From Eduardo Romero Urra (2015-03-03): |
|
1212 # Today has been published officially that Chile will use the DST time |
|
1213 # permanently until March 25 of 2017 |
|
1214 # http://www.diariooficial.interior.gob.cl/media/2015/03/03/1-large.jpg |
|
1215 # |
|
1216 # From Paul Eggert (2015-03-03): |
|
1217 # For now, assume that the extension will persist indefinitely. |
|
1218 |
|
1219 # From Juan Correa (2016-03-18): |
|
1220 # The decree regarding DST has been published in today's Official Gazette: |

|
1222 # http://www.leychile.cl/Navegar?idNorma=1088502 |
|
1223 # It does consider the second Saturday of May and August as the dates |
|
1224 # for the transition; and it lists DST dates until 2019, but I think |
|
1225 # this scheme will stick. |
|
1226 # |
|
1227 # From Paul Eggert (2016-03-18): |
|
1228 # For now, assume the pattern holds for the indefinite future. |
|
1229 # The decree says transitions occur at 24:00; in practice this appears |
|
1230 # to mean 24:00 mainland time, not 24:00 local time, so that Easter |
|
1231 # Island is always two hours behind the mainland. |
|
1232 |
|
1233 # From Juan Correa (2016-12-04): |
|

1239 # From Paul Eggert (2017-01-19): |
|
1240 # The above says the Magallanes change expires 2019-05-11 at 24:00, |
|
1241 # so in theory, they will revert to -04/-03 after that, which means |
|
1242 # they will switch from -03 to -04 one hour after Santiago does that day. |
|
1243 # For now, assume that they will not revert. |

1430 # |
|
1431 # I have communicated several times with people there, and the last |
|
1432 # time I had communications that was helpful was in 1998. Here is |
|
1433 # what was said then: |
|
1434 # |
|
1435 # "The general rule was that Stanley used daylight saving and the Camp |
|
1436 # did not. However for various reasons many people in the Camp have |
|
1437 # started to use daylight saving (known locally as 'Stanley Time') |
|
1438 # There is no rule as to who uses daylight saving - it is a matter of |
|
1439 # personal choice and so it is impossible to draw a map showing who |
|
1440 # uses it and who does not. Any list would be out of date as soon as |
|
1441 # it was produced. This year daylight saving ended on April 18/19th |
|
1442 # and started again on September 12/13th. I do not know what the rule |
|
1443 # is, but can find out if you like. We do not change at the same time |
|
1444 # as UK or Chile." |
|
1445 # |
|
1446 # I did have in my notes that the rule was "Second Saturday in Sep at |
|
1447 # 0:00 until third Saturday in Apr at 0:00". I think that this does |
|
1448 # not agree in some cases with Shanks; is this true? |
|
1449 # |
|
1450 # Also, there is no mention in the list that some areas in the |
|
1451 # Falklands do not use DST. I have found in my communications there |
|
1452 # that these areas are on the western half of East Falkland and all of |
|
1453 # West Falkland. Stanley is the only place that consistently observes |
|
1454 # DST. Again, as in other places in the world, the farmers don't like |
|
1455 # it. West Falkland is almost entirely sheep farmers. |
|
1456 # |
|
1457 # I know one lady there that keeps a list of which farm keeps DST and |
|
1458 # which doesn't each year. She runs a shop in Stanley, and says that |
|
1459 # the list changes each year. She uses it to communicate to her |
|
1460 # customers, catching them when they are home for lunch or dinner. |
|
1461 |
|
1462 # From Paul Eggert (2001-03-05): |
