How windows behaves during the daylight savings time change depends on the version of windows and how the time is stored. If it is stored as a FILETIME, then the time changes with the timezone. If it is stored as a time_t or similar, then the time remains static with a timezone change. FILETIME is always stored in UTC and converted for display, time_t is stored as local time, and just displayed.
