-* File TIMEZONE.CPP
-*
-* Modification History:
-*
-* Date Name Description
-* 12/05/96 clhuang Creation.
-* 04/21/97 aliu General clean-up and bug fixing.
-* 05/08/97 aliu Fixed Hashtable code per code review.
-* 07/09/97 helena Changed createInstance to createDefault.
-* 07/29/97 aliu Updated with all-new list of 96 UNIX-derived
-* TimeZones. Changed mechanism to load from static
-* array rather than resource bundle.
-* 07/07/1998 srl Bugfixes from the Java side: UTC GMT CAT NST
-* Added getDisplayName API
-* going to add custom parsing.
-*
-* ISSUES:
-* - should getDisplayName cache something?
-* - should custom time zones be cached? [probably]
-* 08/10/98 stephen Brought getDisplayName() API in-line w/ conventions
-* 08/19/98 stephen Changed createTimeZone() to never return 0
-* 09/02/98 stephen Added getOffset(monthLen) and hasSameRules()
-* 09/15/98 stephen Added getStaticClassID()
-* 02/22/99 stephen Removed character literals for EBCDIC safety
-* 05/04/99 stephen Changed initDefault() for Mutex issues
-* 07/12/99 helena HPUX 11 CC Port.
-* 12/03/99 aliu Moved data out of static table into icudata.dll.
-* Substantial rewrite of zone lookup, default zone, and
-* available IDs code. Misc. cleanup.
