Time zones from Windows XP

I am new in this mailing list so, please, forgive me if this has been asked before. I'm trying to map the list of time zones that Windows XP includes, to the correct binary files in tz Database, but I am missing some of them. I just could not find which one to use or if it is supported at all. Here is the list: (GMT - 12:00) International Date Line West (GMT - 06:00) Central America (GMT - 03:00) Brasilia (GMT - 02:00) Mid-Atlantic (GMT + 01:00) West Central Africa (GMT + 06:00) Sri Jayawardenepura (GMT + 13:00) Nuku’alofa Also, is there any site where I can find documentation about this library? Thanks a lot for your help. RBallen
