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