763 * NOTE: As of ICU 2.8, this test confirms that the "tz.alias"
764 * file, used to build ICU alias zones, is working. It also
765 * looks at some genuine Olson compatibility IDs. [aliu]
766 *
767 * This test is problematic. It should really just confirm that
768 * the list of compatibility zone IDs exist and are somewhat
769 * meaningful (that is, they aren't all aliases of GMT). It goes a
770 * bit further -- it hard-codes expectations about zone behavior,
771 * when in fact zones are redefined quite frequently. ICU's build
772 * process means that it is easy to update ICU to contain the
773 * latest Olson zone data, but if a zone tested here changes, then
774 * this test will fail. I have updated the test for 1999j data,
775 * but further updates will probably be required. Note that some
776 * of the concerts listed below no longer apply -- in particular,
777 * we do NOT overwrite real UNIX zones with 3-letter IDs. There
778 * are two points of overlap as of 1999j: MET and EET. These are
779 * both real UNIX zones, so we just use the official
780 * definition. This test has been updated to reflect this.
781 * 12/3/99 aliu
782 *
783 * Added tests for additional zones and aliases from the icuzones file.
784 * Markus Scherer 2006-nov-06
785 *
786 * [srl - from java - 7/5/1998]
787 * @bug 4130885
788 * Certain short zone IDs, used since 1.1.x, are incorrect.
789 *
790 * The worst of these is:
791 *
792 * "CAT" (Central African Time) should be GMT+2:00, but instead returns a
793 * zone at GMT-1:00. The zone at GMT-1:00 should be called EGT, CVT, EGST,
794 * or AZOST, depending on which zone is meant, but in no case is it CAT.
795 *
796 * Other wrong zone IDs:
797 *
798 * ECT (European Central Time) GMT+1:00: ECT is Ecuador Time,
799 * GMT-5:00. European Central time is abbreviated CEST.
800 *
801 * SST (Solomon Island Time) GMT+11:00. SST is actually Samoa Standard Time,
802 * GMT-11:00. Solomon Island time is SBT.
803 *
804 * NST (New Zealand Time) GMT+12:00. NST is the abbreviation for
805 * Newfoundland Standard Time, GMT-3:30. New Zealanders use NZST.
806 *
807 * AST (Alaska Standard Time) GMT-9:00. [This has already been noted in
808 * another bug.] It should be "AKST". AST is Atlantic Standard Time,
809 * GMT-4:00.
810 *
811 * PNT (Phoenix Time) GMT-7:00. PNT usually means Pitcairn Time,
812 * GMT-8:30. There is no standard abbreviation for Phoenix time, as distinct
813 * from MST with daylight savings.
814 *
815 * In addition to these problems, a number of zones are FAKE. That is, they
816 * don't match what people use in the real world.
817 *
818 * FAKE zones:
819 *
820 * EET (should be EEST)
821 * ART (should be EEST)
822 * MET (should be IRST)
823 * NET (should be AMST)
824 * PLT (should be PKT)
825 * BST (should be BDT)
826 * VST (should be ICT)
827 * CTT (should be CST) +
828 * ACT (should be CST) +
829 * AET (should be EST) +
830 * MIT (should be WST) +
831 * IET (should be EST) +
832 * PRT (should be AST) +
833 * CNT (should be NST)
834 * AGT (should be ARST)
835 * BET (should be EST) +
836 *
837 * + A zone with the correct name already exists and means something
838 * else. E.g., EST usually indicates the US Eastern zone, so it cannot be
839 * used for Brazil (BET).
