Countries not 5*40003Sbostic# listed here do not observe DST, according to the OAG. Time zone names 6*40003Sbostic# are pure inventions, and none are supplied for countries not observing 7*40003Sbostic# DST; updates from natives would be appreciated. The times that DST 8*40003Sbostic# starts and ends are based on the assumption that they switch a 2AM just 9*40003Sbostic# as everybody else does. 10*40003Sbostic 11*40003Sbostic############################################################################### 12*40003Sbostic 13*40003Sbostic# Brazil 14*40003Sbostic 15*40003Sbostic# From Guy Harris: 16*40003Sbostic# The OAG lists October 25, 1987 and February 12, 1988 as the starting and 17*40003Sbostic# ending dates, giving them as "estimated date(s) based on previous year".
