    759  * NOTE: As of ICU 2.8, this test confirms that the "tz.alias"
    760  * file, used to build ICU alias zones, is working.  It also
    761  * looks at some genuine Olson compatibility IDs. [aliu]
    762  *
    763  * This test is problematic. It should really just confirm that
    764  * the list of compatibility zone IDs exist and are somewhat
    765  * meaningful (that is, they aren't all aliases of GMT). It goes a
    766  * bit further -- it hard-codes expectations about zone behavior,
    767  * when in fact zones are redefined quite frequently. ICU's build
    768  * process means that it is easy to update ICU to contain the
    769  * latest Olson zone data, but if a zone tested here changes, then
    770  * this test will fail.  I have updated the test for 1999j data,
    771  * but further updates will probably be required. Note that some
    772  * of the concerts listed below no longer apply -- in particular,
    773  * we do NOT overwrite real UNIX zones with 3-letter IDs. There
    774  * are two points of overlap as of 1999j: MET and EET. These are
    775  * both real UNIX zones, so we just use the official
    776  * definition. This test has been updated to reflect this.
    777  * 12/3/99 aliu
    778  *
    779  * Added tests for additional zones and aliases from the icuzones file.

    782  * [srl - from java - 7/5/1998]
    783  * @bug 4130885
    784  * Certain short zone IDs, used since 1.1.x, are incorrect.
    785  *
    786  * The worst of these is:
    787  *
    788  * "CAT" (Central African Time) should be GMT+2:00, but instead returns a
    789  * zone at GMT-1:00. The zone at GMT-1:00 should be called EGT, CVT, EGST,
    790  * or AZOST, depending on which zone is meant, but in no case is it CAT.
    791  *
    792  * Other wrong zone IDs:
    793  *
    794  * ECT (European Central Time) GMT+1:00: ECT is Ecuador Time,
    795  * GMT-5:00. European Central time is abbreviated CEST.
    796  *
    797  * SST (Solomon Island Time) GMT+11:00. SST is actually Samoa Standard Time,
    798  * GMT-11:00. Solomon Island time is SBT.
    799  *
    800  * NST (New Zealand Time) GMT+12:00. NST is the abbreviation for
    801  * Newfoundland Standard Time, GMT-3:30. New Zealanders use NZST.
    802  *
    803  * AST (Alaska Standard Time) GMT-9:00. [This has already been noted in
    804  * another bug.] It should be "AKST". AST is Atlantic Standard Time,
    805  * GMT-4:00.
    806  *
    807  * PNT (Phoenix Time) GMT-7:00. PNT usually means Pitcairn Time,
    808  * GMT-8:30. There is no standard abbreviation for Phoenix time, as distinct
    809  * from MST with daylight savings.
    810  *
    811  * In addition to these problems, a number of zones are FAKE. That is, they
    812  * don't match what people use in the real world.
    813  *
    814  * FAKE zones:
    815  *
    816  * EET (should be EEST)
    817  * ART (should be EEST)
    818  * MET (should be IRST)
    819  * NET (should be AMST)
    820  * PLT (should be PKT)
    821  * BST (should be BDT)
    822  * VST (should be ICT)
    823  * CTT (should be CST) +
    824  * ACT (should be CST) +
    825  * AET (should be EST) +
    826  * MIT (should be WST) +
    827  * IET (should be EST) +
    828  * PRT (should be AST) +
    829  * CNT (should be NST)
    830  * AGT (should be ARST)
    831  * BET (should be EST) +
    832  *
    833  * + A zone with the correct name already exists and means something
    834  * else. E.g., EST usually indicates the US Eastern zone, so it cannot be
    835  * used for Brazil (BET).
