657 619 # From Paul Eggert (1993-11-18):
658 620 # The mayor of Rio recently attempted to change the time zone rules
659 621 # just in his city, in order to leave more summer time for the tourist trade.
660 622 # The rule change lasted only part of the day;
661 623 # the federal government refused to follow the city's rules, and business
662 624 # was in a chaos, so the mayor backed down that afternoon.

634 +# Geography, history (Tocantins was part of Goiás until 1989), and other
673 635 # sources of time zone information lead me to believe that AL, SE, and TO were
674 636 # always in BR1, and so the only change was whether or not they observed DST....
675 637 # The earliest issue of the SSIM I have is 2/91. Each issue from then until
676 638 # 9/95 says that DST is observed only in the ten states I quoted from 9/95,
677 639 # along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
678 640 # (UTC-4).... The other two time zones given for Brazil are BR3, which is
679 641 # UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
680 642 # UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
681 643 # become part of the state of Pernambuco). The boundary between BR1 and BR2
682 644 # has never been clearly stated. They've simply been called East and West.
683 645 # However, some conclusions can be drawn from another IATA manual: the Airline
684 646 # Coding Directory, which lists close to 400 airports in Brazil. For each
685 647 # airport it gives a time zone which is coded to the SSIM. From that

687 -# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do

701 661 # The reason for the delay this year has to do with elections in Brazil.
702 662 #
703 663 # Unlike in the United States, elections in Brazil are 100% computerized and
704 664 # the results are known almost immediately. Yesterday, it was the first
705 665 # round of the elections when 115 million Brazilians voted for President,
706 666 # Governor, Senators, Federal Deputies, and State Deputies. Nobody is
707 667 # counting (or re-counting) votes anymore and we know there will be a second
708 668 # round for the Presidency and also for some Governors. The 2nd round will
709 669 # take place on October 27th.
710 670 #
711 671 # The reason why the DST will only begin November 3rd is that the thousands
712 672 # of electoral machines used cannot have their time changed, and since the
713 673 # Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
714 674 # the Government decided to postpone DST, instead of changing the Constitution
715 675 # (maybe, for the next elections, it will be possible to change the clock)...

1421 1352 # I have communicated several times with people there, and the last
1422 1353 # time I had communications that was helpful was in 1998. Here is
1423 1354 # what was said then:
1424 1355 #
1425 1356 # "The general rule was that Stanley used daylight saving and the Camp
1426 1357 # did not. However for various reasons many people in the Camp have
1427 1358 # started to use daylight saving (known locally as 'Stanley Time')
1428 1359 # There is no rule as to who uses daylight saving - it is a matter of
1429 1360 # personal choice and so it is impossible to draw a map showing who
1430 1361 # uses it and who does not. Any list would be out of date as soon as
1431 1362 # it was produced. This year daylight saving ended on April 18/19th
1432 1363 # and started again on September 12/13th. I do not know what the rule
1433 1364 # is, but can find out if you like. We do not change at the same time
1434 1365 # as UK or Chile."
1435 1366 #
1436 1367 # I did have in my notes that the rule was "Second Saturday in Sep at
1437 1368 # 0:00 until third Saturday in Apr at 0:00". I think that this does
1438 1369 # not agree in some cases with Shanks; is this true?
1439 1370 #
1440 1371 # Also, there is no mention in the list that some areas in the
1441 1372 # Falklands do not use DST. I have found in my communications there
1442 1373 # that these areas are on the western half of East Falkland and all of
1443 1374 # West Falkland. Stanley is the only place that consistently observes
1444 1375 # DST. Again, as in other places in the world, the farmers don't like
1445 1376 # it. West Falkland is almost entirely sheep farmers.
1446 1377 #
1447 1378 # I know one lady there that keeps a list of which farm keeps DST and
1448 1379 # which doesn't each year. She runs a shop in Stanley, and says that
1449 1380 # the list changes each year. She uses it to communicate to her
1450 1381 # customers, catching them when they are home for lunch or dinner.
