The Win32 SetSystemTime API function offers the functionality to change the system time on the local machine. The change will take place immediately without the need for a reboot. This article illustrates how to create a sample project that sets the system time using the SetSystemTime function. The SetSystemTime function sets the system time based on coordinated universal time (UTC). UTC-based time is loosely defined as the current date and time of day in Greenwich, England.
The SYSTEMTIME Type structure is as follows:
WYear Integer-The current year. WMonth Integer-The current month. January is 1. WDayOfWeek Integer-The current day of the week. Sunday is 0. WDay Integer-The current day of the month. WHour Integer-The current hour. wMinute Integer-The current minute. wSecond Integer-The current second. wMilliseconds Integer-The current millisecond.
To change the system time on a Win32 platform from 16-bit Visual Basic, you would have to create a DLL that does a generic thunk to the 32-bit API SetSystemTime.
