One of my computers has Win2k SP4 and I run Boinc and it was just 38
seconds fast! I do not think Boinc has anything to do with the clock!
My wifes computer is XP Home with SP2 and it was just .8 seconds slow
over more than 2 months!

WinXP Home automatically updates the clock once a week, maybe that's why 
it's so accurate. ;)
