It will not work for date before 1980. terryk 30-Nov-91 Change _ptmTime to _tmTime ( for multiple copy of the object ) Yi-HsinS 5-Dec-92 Restructure to use WIN32 APIs instead of C Runtimes

NAME: WIN_TIME
SYNOPSIS: Wrapper class for WIN32 TIME functions
INTERFACE: WIN_TIME() - construct and set the object to current time or a specified time. ALWAYS PASS THE GMT TIME, even if fStoreAsGMT is FALSE. SetCurrentTime() - set the object to current time. ONLY CALL THIS WHEN _fStoreAsGMT IS TRUE! SetTime() - set the object to a specified time. The time value represents the seconds elapsed since 00:00:00 January 1,1970. However it will not work for date prior to January 1980. ALWAYS PASS THE GMT TIME, even if _fStoreAsGMT is FALSE. SetGMT() - set the present method to local time or GMT time
These methods set a component of the time:
SetHour() - set the hour field ( 0-23 ) SetMinute() - set the minute field ( 0-59 ) SetSecond() - set the second field ( 0-59 ) SetMilliseconds() - set the millisecond field ( 0-999 ) SetYear() - set the year field ( e.g. 1992 ) SetMonth() - set the month field ( 1-12, 1-January ) SetDay() - set day of month field ( 1-31 )
Normalize() - set the DayofWeek and year day appropriately. Always call this after you are finished calling the Set[component] methods and before you use the WIN_TIME in any other way.
QueryTime() - return the time in ULONG format ( the second elapsed since 00:00:00, January 1, 1970.) Always returns GMT time regardless of _fStoreAsGMT. QueryFileTime() - return the GMT time in FILETIME format Always returns GMT time regardless of _fStoreAsGMT. QueryLocalTime() - return the time in ULONG format ( the second elapsed since 00:00:00, January 1, 1970.) Always returns local time regardless of _fStoreAsGMT. QueryLocalTime() - return the GMT time in FILETIME format Always returns local time regardless of _fStoreAsGMT.
These APIs return a component of the time:
QueryHour() - return hour field value ( 0-23 ) QueryMinute() - return minute field value ( 0-59 ) QuerySecond() - return second field value ( 0-59 ) QueryMilliseconds() - return the millisecond field value ( 0-999) QueryYear() - return year field value ( e.g. 1992 ) QueryMonth() - return month field value ( 1-12, 1-January ) QueryDay() - return Day field value ( 1- 31 ) QueryDayOfWeek() - return day of week field value ( 0 - 6, Sunday = 0 )
NOTES: WIN_TIME stores time internally in either local time or GMT time, depending on the setting of the _fStoreAsGMT flag.
