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 date
