27# Earlier editions of these tables used the North American style (e.g. ARST and 28# ARDT for Argentine Standard and Daylight Time), but the following quote 29# suggests that it's better to use European style (e.g. ART and ARST). 30# I suggest the use of _Summer time_ instead of the more cumbersome 31# _daylight-saving time_. _Summer time_ seems to be in general use 32# in Europe and South America. 33# -- E O Cutler, _New York Times_ (1937-02-14), quoted in 34# H L Mencken, _The American Language: Supplement I_ (1960), p 466 35# 36# Earlier editions of these tables also used the North American style 37# for time zones in Brazil, but this was incorrect, as Brazilians say 38# "summer time". Reinaldo Goulart, a S��o Paulo businessman active in 39# the railroad sector, writes (1999-07-06): 40# The subject of time zones is currently a matter of discussion/debate in 41# Brazil. Let's say that "the Bras��lia time" is considered the 42# "official time" because Bras��lia is the capital city. 43# The other three time zones are called "Bras��lia time "minus one" or 44# "plus one" or "plus two". As far as I know there is no such 45# name/designation as "Eastern Time" or "Central Time". 46# So I invented the following (English-language) abbreviations for now. 47# Corrections are welcome! 48# std dst 49# -2:00 FNT FNST Fernando de Noronha 50# -3:00 BRT BRST Bras��lia 51# -4:00 AMT AMST Amazon 52# -5:00 ACT ACST Acre | 27# These tables use numeric abbreviations like -03 and -0330 for 28# integer hour and minute UTC offsets. Although earlier editions used 29# alphabetic time zone abbreviations, these abbreviations were 30# invented and did not reflect common practice. |
