Declare Function LocalFileTimeToFileTime Lib "kernel32.dll" (lpLocalFileTime As FILETIME, lpFileTime As FILETIME) As Long
Platforms: Win 32s, Win 95/98, Win NT
LocalFileTimeToFileTime converts a time from local time (time according to the computer's current time zone) to UTC time (also known as Greenwich Mean Time). The source and target times are stored in FILETIME format. The function returns 1 if successful, or 0 if an error occured.
Example:
' Convert the time and date May 1, 1999 6:10:00 PM local time
' to a FILETIME structure in UTC time.
Dim sourcetime As SYSTEMTIME ' original time and date
Dim localtime As FILETIME ' receives sourcetime's time
Dim utctime As FILETIME ' receives the final result
Dim retval As Long ' return value
' Set sourcetime to the desired date:
sourcetime.wMonth = 5: sourcetime.wDay = 1: sourcetime.wYear = 1999
sourcetime.wHour = 18: sourcetime.wMinute = 10: sourcetime.wSecond = 0
' Convert sourcetime into FILETIME format:
retval = SystemTimeToFileTime(sourcetime, localtime)
' Convert localtime into UTC time:
retval = LocalFileTimeToFileTime(localtime, utctime)
' utctime now has the converted time and dateSee Also: FileTimeToLocalFileTime
