Shanks and Rique Pottenger, The International Atlas (6th edition), 12 # San Diego: ACS Publications, Inc. (2003). 13 # 14 # Gwillim Law writes that a good source 15 # for recent time zone data is the International Air Transport 16 # Association's Standard Schedules Information Manual (IATA SSIM), 17 # published semiannually. Law sent in several helpful summaries 18 # of the IATA's data after 1990. 19 # 20 # Except where otherwise noted, Shanks & Pottenger is the source for 21 # entries through 1990, and IATA SSIM is the source for entries afterwards. 22 # 23 # Earlier editions of these tables used the North American style (e.g. ARST and 24 # ARDT for Argentine Standard and Daylight Time), but the following quote 25 # suggests that it's better to use European style (e.g. ART and ARST). 26 # I suggest the use of _Summer time_ instead of the more cumbersome 27 # _daylight-saving time_. _Summer time_ seems to be in general use 28 # in Europe and South America. 29 # -- E O Cutler, _New York Times_ (1937-02-14), quoted in 30 # H L Mencken, _The American Language: Supplement I_ (1960), p 466 31 # 32 # Earlier editions of these tables also used the North American style 33 # for time zones in Brazil, but this was incorrect, as Brazilians say 34 # "summer time". Reinaldo Goulart, a Sao Paulo businessman active in 35 # the railroad sector, writes (1999-07-06): 36 # The subject of time zones is currently a matter of discussion/debate in 37 # Brazil. Let's say that "the Brasilia time" is considered the 38 # "official time" because Brasilia is the capital city. 39 # The other three time zones are called "Brasilia time "minus one" or 40 # "plus one" or "plus two". As far as I know there is no such 41 # name/designation as "Eastern Time" or "Central Time". 42 # So I invented the following (English-language) abbreviations for now. 43 # Corrections are welcome! 44 # std dst 45 # -2:00 FNT FNST Fernando de Noronha 46 # -3:00 BRT BRST Brasilia 47 # -4:00 AMT AMST Amazon 48 # -5:00 ACT ACST Acre 49 50 ############################################################################### 51 52 ############################################################################### 53 54 # Argentina 55 56 # From Bob Devine (1988-01-28): 57 # Argentina: first Sunday in October to first Sunday in April since 1976. 58 # Double Summer time from 1969 to 1974.

The other two time zones given for Brazil are BR3, which is 673 # UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is 674 # UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's 675 # become part of the state of Pernambuco). The boundary between BR1 and BR2 676 # has never been clearly stated.
