Use GetSystemTime() win32API function to get the GMT time.
Use GetLocalTime() Wind32API function to get the local time. It also takes into account the daylight savings.

Your Windows must be correctly setup in order to have correct results with GetLocalTime().

Look in the KB here on UT for an example (Michel Fournier) on how to use these functions.
