The zone at GMT-1:00 should be called EGT, CVT, EGST, * or AZOST, depending on which zone is meant, but in no case is it CAT. * * Other wrong zone IDs: * * ECT (European Central Time) GMT+1:00: ECT is Ecuador Time, * GMT-5:00. European Central time is abbreviated CEST. * * SST (Solomon Island Time) GMT+11:00. SST is actually Samoa Standard Time, * GMT-11:00. Solomon Island time is SBT. * * NST (New Zealand Time) GMT+12:00. NST is the abbreviation for * Newfoundland Standard Time, GMT-3:30. New Zealanders use NZST. * * AST (Alaska Standard Time) GMT-9:00. [This has already been noted in * another bug.] It should be "AKST". AST is Atlantic Standard Time, * GMT-4:00. * * PNT (Phoenix Time) GMT-7:00. PNT usually means Pitcairn Time, * GMT-8:30. There is no standard abbreviation for Phoenix time, as distinct * from MST with daylight savings. * * In addition to these problems, a number of zones are FAKE.
