* Modification History:
*
* Date Name Description
* 02/03/97 clhuang Creation.
* 04/22/97 aliu Cleaned up, fixed memory leak, made
* setWeekCountData() more robust.
* Moved platform code to TPlatformUtilities.
* 05/01/97 aliu Made equals(), before(), after() arguments const.
* 05/20/97 aliu Changed logic of when to compute fields and time
* to fix bugs.
* 08/12/97 aliu Added equivalentTo. Misc other fixes.
* 07/28/98 stephen Sync up with JDK 1.2
* 09/02/98 stephen Sync with JDK 1.2 8/31 build (getActualMin/Max)
* 03/17/99 stephen Changed adoptTimeZone() - now fAreFieldsSet is
* set to FALSE to force update of time.

// Data flow in Calendar
// ---------------------
// The current time is represented in two ways by Calendar: as UTC
// milliseconds from the epoch start (1 January 1970 0:00 UTC), and as local
// fields such as MONTH, HOUR, AM_PM, etc. It is possible to compute the
// millis from the fields, and vice versa. The data needed to do this
// conversion is encapsulated by a TimeZone object owned by the Calendar.
// The data provided by the TimeZone object may also be overridden if the
// user sets the ZONE_OFFSET and/or DST_OFFSET fields directly. The class
// keeps track of what information was most recently set by the caller, and
// uses that to compute any other information as needed.
// If the user sets the fields using set(), the data flow is as follows.
// This is implemented by the Calendar subclass's computeTime() method.
// During this process, certain fields may be ignored. The disambiguation
// algorithm for resolving which fields to pay attention to is described
// above.
// local fields (YEAR, MONTH, DATE, HOUR, MINUTE, etc.)
// |
// | Using Calendar-specific algorithm
// V
// local standard millis
// |
// | Using TimeZone or user-set ZONE_OFFSET / DST_OFFSET
// V
// UTC millis (in time data member)
// If the user sets the UTC millis using setTime(), the data flow is as
// follows. This is implemented by the Calendar subclass's computeFields()
// method.
// UTC millis (in time data member)
// |
// | Using TimeZone getOffset()
// V
// local standard millis
// |
// | Using Calendar-specific algorithm
// V
// local fields (YEAR, MONTH, DATE, HOUR, MINUTE, etc.)
// In general, a round trip from fields, through local and UTC millis, and
// back out to fields is made when necessary. This is implemented by the
// complete() method. Resolving a partial set of fields into a UTC millis
// value allows all remaining fields to be generated from that value. If
// the Calendar is lenient, the fields are also renormalized to standard
// ranges when they are regenerated.

* account other relevant fields. In general these other fields are
* larger fields. For example, when computing the actual maximum
* DATE, the current value of DATE itself is ignored,
* as is the value of any field smaller.
*
* <p>The time fields all have fixed minima and maxima, so we don't
* need to worry about them. This also lets us set the
* MILLISECONDS_IN_DAY to zero to erase any effects the time fields
* might have when computing date fields.
