| * 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. |
