Recently, my 'puter clock has been resetting back an hour every so often.
The auto-sync to time.NIST.gov is the timeserver it uses.

Does that site change to Daylight time?
Does the Windows time site change to aylight time?




Internally, Windows (like UNIX systems) uses UTC, and that can be kept 
correct by e.g. the NTP software:


Windows own timekeeping software is not as robust or accurate.  What you see 
displayed is determined by your Control Panel settings, and that should be 
under your control.  Summer/Winter time settings for a particular time zone 
are what determines how Windows internal UTC is presented to you.

(If you dual-boot between Windows and UNIX, there are other issues.)
