* File GREGOCAL.CPP
*
* Modification History:
*
* Date Name Description
* 02/05/97 clhuang Creation.
* 03/28/97 aliu Made highly questionable fix to computeFields to
* handle DST correctly.
* 04/22/97 aliu Cleaned up code drastically. Added monthLength().
* Finished unimplemented parts of computeTime() for
* week-based date determination. Removed quetionable
* fix and wrote correct fix for computeFields() and
* daylight time handling. Rewrote inDaylightTime()
* and computeFields() to handle sensitive Daylight to
* Standard time transitions correctly.
* 05/08/97 aliu Added code review changes. Fixed isLeapYear() to
* not cutover.
* 08/12/97 aliu Added equivalentTo. Misc other fixes. Updated
* add() from Java source.
* 07/28/98 stephen Sync up with JDK 1.2
* 09/14/98 stephen Changed type of kOneDay, kOneWeek to double.
* Fixed bug in roll()
* 10/15/99 aliu Fixed j31, incorrect WEEK_OF_YEAR computation.
* 10/15/99 aliu Fixed j32, cannot set date to Feb 29 2000 AD.
* {JDK bug 4210209 4209272}
* 11/15/99 weiv Added YEAR_WOY and DOW_LOCAL computation
* to timeToFields method, updated kMinValues, kMaxValues & kLeastMaxValues
* 12/09/99 aliu Fixed j81, calculation errors and roll bugs
* in year of cutover.
* 01/24/2000 aliu Revised computeJulianDay for YEAR YEAR_WOY WOY.
