This is way outside what ntpd can correct for (limit is 500 ppm), at best you will see the clock being stepped back repeatedly. >From this single sample it could be thought that it was actually 172.16.2.2 falling behind, but your other posts indicate that it is server-independant. I believe this is also way too much to simply be a "bad clock", and since it is running fast, it can't be due to lost timer interrupts. Maybe there are BIOS settings that can cause this, I've seen hints to that effect in other threads, but I have no persoal experience with that. Just thought I should point out this obvious problem since it seems to have been overlooked by others commenting... --Per Hedeland [EMAIL PROTECTED] _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
