Here's two others I have in the pool, that show a different large offset (not 10 up/10 down, but 20 down) just around the same time, somewhat "confirming" that it might not be just your server but rather network on the monitoring server (or an offset on the monitoring server itself). http://www.pool.ntp.org/scores/87.233.14.148/graph/offset.png http://www.pool.ntp.org/scores/213.239.154.12/graph/offset.png (both can be found at http://www.pool.ntp.org/user/Roelant) These are both servers I know to be reliable, but "hiccups" still occur. That's to be considered normal when you're dealing with networks and (an attempt to) millisecond-accuracy services. Monitoring-graphs are a good tool and a give a good indication, but they're not perfect. :-) Regards, Roelant. _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
