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.
