Countries not 5*8c8db7cfSbostic# listed here do not observe DST, according to the OAG. Time zone names 6*8c8db7cfSbostic# are pure inventions, and none are supplied for countries not observing 7*8c8db7cfSbostic# DST; updates from natives would be appreciated. The times that DST 8*8c8db7cfSbostic# starts and ends are based on the assumption that they switch a 2AM just 9*8c8db7cfSbostic# as everybody else does. 10*8c8db7cfSbostic 11*8c8db7cfSbostic############################################################################### 12*8c8db7cfSbostic 13*8c8db7cfSbostic# Brazil 14*8c8db7cfSbostic 15*8c8db7cfSbostic# From Guy Harris: 16*8c8db7cfSbostic# The OAG lists October 25, 1987 and February 12, 1988 as the starting and 17*8c8db7cfSbostic# ending dates, giving them as "estimated date(s) based on previous year".
