752 * NOTE: As of ICU 2.8, this test confirms that the "tz.alias"
753 * file, used to build ICU alias zones, is working. It also
754 * looks at some genuine Olson compatibility IDs. [aliu]
755 *
756 * This test is problematic. It should really just confirm that
757 * the list of compatibility zone IDs exist and are somewhat
758 * meaningful (that is, they aren't all aliases of GMT). It goes a
759 * bit further -- it hard-codes expectations about zone behavior,
760 * when in fact zones are redefined quite frequently. ICU's build
761 * process means that it is easy to update ICU to contain the
762 * latest Olson zone data, but if a zone tested here changes, then
763 * this test will fail. I have updated the test for 1999j data,
764 * but further updates will probably be required. Note that some
765 * of the concerts listed below no longer apply -- in particular,
766 * we do NOT overwrite real UNIX zones with 3-letter IDs. There
767 * are two points of overlap as of 1999j: MET and EET. These are
768 * both real UNIX zones, so we just use the official
769 * definition. This test has been updated to reflect this.
770 * 12/3/99 aliu
771 *
772 * Added tests for additional zones and aliases from the icuzones file.
773 * Markus Scherer 2006-nov-06
774 *
775 * [srl - from java - 7/5/1998]
776 * @bug 4130885
777 * Certain short zone IDs, used since 1.1.x, are incorrect.
778 *
779 * The worst of these is:
780 *
781 * "CAT" (Central African Time) should be GMT+2:00, but instead returns a
782 * zone at GMT-1:00. The zone at GMT-1:00 should be called EGT, CVT, EGST,
783 * or AZOST, depending on which zone is meant, but in no case is it CAT.
784 *
785 * Other wrong zone IDs:
786 *
787 * ECT (European Central Time) GMT+1:00: ECT is Ecuador Time,
788 * GMT-5:00. European Central time is abbreviated CEST.
789 *
790 * SST (Solomon Island Time) GMT+11:00. SST is actually Samoa Standard Time,
791 * GMT-11:00. Solomon Island time is SBT.
792 *
793 * NST (New Zealand Time) GMT+12:00. NST is the abbreviation for
794 * Newfoundland Standard Time, GMT-3:30. New Zealanders use NZST.
795 *
796 * AST (Alaska Standard Time) GMT-9:00. [This has already been noted in
797 * another bug.] It should be "AKST". AST is Atlantic Standard Time,
798 * GMT-4:00.
799 *
800 * PNT (Phoenix Time) GMT-7:00. PNT usually means Pitcairn Time,
801 * GMT-8:30. There is no standard abbreviation for Phoenix time, as distinct
802 * from MST with daylight savings.
803 *
804 * In addition to these problems, a number of zones are FAKE. That is, they
805 * don't match what people use in the real world.
806 *
807 * FAKE zones:
808 *
809 * EET (should be EEST)
810 * ART (should be EEST)
811 * MET (should be IRST)
812 * NET (should be AMST)
813 * PLT (should be PKT)
814 * BST (should be BDT)
815 * VST (should be ICT)
816 * CTT (should be CST) +
817 * ACT (should be CST) +
818 * AET (should be EST) +
819 * MIT (should be WST) +
820 * IET (should be EST) +
821 * PRT (should be AST) +
822 * CNT (should be NST)
823 * AGT (should be ARST)
824 * BET (should be EST) +
825 *
826 * + A zone with the correct name already exists and means something
827 * else. E.g., EST usually indicates the US Eastern zone, so it cannot be
828 * used for Brazil (BET).
