The Microsoft time functions calculate for daylight saving time. In particular, mktime() will set the hour ahead or back one hour according to the rules of daylight saving time. The only way to change the dates that the time functions use in calculating daylight saving time is to get the run-time library source code available for the time functions and modify the routine _isindst() in the file TZSET.C.
