I was wondering how to sync my windows xp clock? When I try to sync with servers ( or it fails to sync.. Do you know any good server or solution?

Ummm... Yeah... Do you get any error messages? How do you know it's not synching? Is your TZ set correctly? Do you have the appropariate DST patches installed? – joeqwerty Dec 20 '10 at 19:30
It says in the clock window: The time sample was rejected because: The peer's stratum is less than the host's stratum. – Rihards Dec 20 '10 at 19:36
Do you have the relevant DST updates installed? – joeqwerty Dec 20 '10 at 19:45

The error that you've been given by Windows often occurs on DST changes (but does occur sometimes at other times), it's just that the default Microsoft NTP servers are out of sync (that's not technically correct, but it should help explain it :) ). It probably indicates that you're behind the time being provided by the host's reference clock.

Microsoft servers often have this problem. The best way to alleviate problems like this is to switch to a more reliable time server, I use

I'm not exactly a wizard with NTP though, so some of this may not have incredible technical accuracy, but the end result should be satisfactory. :)

I use Karen's Time Sync. works like a charm, and you can set the time server it asks and the interval.
