No. Windows uses UTC for internal timekeeping. Timezones are only for local display of time, just like Unix. Notice that you need to nothing to go between daylight savings time and local standard time in any timezone. VMS is the only operating system that I am aware of that uses local time for internal timekeeping, and that may have changed since I was involved with it. I don't know what IBM mainframes do.
