XP SP3 clocks fell back too early

A few XP Pro clients fell back an hour I noticed today on a WS2003 domain.  Ive verified the XP clients are set for the correct time zone: US GMT -6:00 Central Time (US and Canada).  As a local admin I changed the time to correct, then logged out.  A few moments after the regular user logs in, the clock falls back an hour.  Both DCs clocks are correct.  They were fully patched last year and they are 2003 SP2.  I notice that the problem computers were from XP SP3 slipstreamed installs.

KB931836 should be in XP SP3. Try to deploy it on 1 machine and see if it does the trick...

KB931836  is the DTS adjustment for 2007 which, as you stated, should be in SP3 alerady.
This is the download link for KB951072 (the article from above) that should fix your issue on your XP machines:

951072 needed to be applied.  Clocks read correct immediately after patch applied (no restart needed).   Affected only slipstreamed XP SP3 installs.  I don't believe "naked" SP3 has any DST update integrated.  Introducing these naked SP3 machines to the domain which uses WSUS 2.0 which had the superseded DST update approved, but probably won't install on SP3 (SP3 is too new for that superseded DST update).  The 951072 wasn't approved yet in WSUS since it didn't geographically apply to Central Time Zone US, and the other fix was approved long ago and had been working fine previous to SP3.  This goes against strong expectations that XP SP3 didn't have some kind of DST fix integrated.  Machines that were SP2 and then had SP3 were not affected (since they got the superseded DST patch while at SP2).

Just wanted to confirm that this is only happening on my PC's with slipstreamed SP3.  Those that received SP3 via WU do not need it.
