/**
* NOTE: As of ICU 2.8, this test confirms that the "tz.alias"
* file, used to build ICU alias zones, is working. It also
* looks at some genuine Olson compatibility IDs. [aliu]
*
* This test is problematic. It should really just confirm that
* the list of compatibility zone IDs exist and are somewhat
* meaningful (that is, they aren't all aliases of GMT). It goes a
* bit further -- it hard-codes expectations about zone behavior,
* when in fact zones are redefined quite frequently. ICU's build
* process means that it is easy to update ICU to contain the
* latest Olson zone data, but if a zone tested here changes, then
* this test will fail. I have updated the test for 1999j data,
* but further updates will probably be required. Note that some
* of the concerts listed below no longer apply -- in particular,
* we do NOT overwrite real UNIX zones with 3-letter IDs. There
* are two points of overlap as of 1999j: MET and EET. These are
* both real UNIX zones, so we just use the official
* definition. This test has been updated to reflect this.
* 12/3/99 aliu
*
* [srl - from java - 7/5/1998]
* @bug 4130885
* Certain short zone IDs, used since 1.1.x, are incorrect.
*
* The worst of these is:
*
* "CAT" (Central African Time) should be GMT+2:00, but instead returns a
* zone at GMT-1:00. 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. That is, they
* don't match what people use in the real world.
*
* FAKE zones:
*
* EET (should be EEST)
* ART (should be EEST)
* MET (should be IRST)
* NET (should be AMST)
* PLT (should be PKT)
* BST (should be BDT)
* VST (should be ICT)
* CTT (should be CST) +
* ACT (should be CST) +
* AET (should be EST) +
* MIT (should be WST) +
* IET (should be EST) +
* PRT (should be AST) +
* CNT (should be NST)
* AGT (should be ARST)
* BET (should be EST) +
*
* + A zone with the correct name already exists and means something
* else. E.g., EST usually indicates the US Eastern zone, so it cannot be
* used for Brazil (BET).
