-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm investigating a problem I'm having with the clock getting very slow, and I have traced the problem to something new in opensuse 10.3. I wonder if any body has the same problem - the check is simple, run this grep command: grep "time reset " /var/log/ntp | less I find: (opensuse 10.2) 23 Feb 02:05:45 ntpd[4617]: time reset +0.624127 s 23 Feb 14:28:52 ntpd[4617]: time reset +0.487172 s 23 Feb 14:49:00 ntpd[4617]: time reset +0.138037 s 23 Feb 22:26:08 ntpd[4617]: time reset +0.243491 s 24 Feb 11:54:28 ntpd[4674]: time reset +0.495337 s 25 Feb 11:56:40 ntpd[4674]: time reset +0.380593 s 27 Feb 11:39:30 ntpd[4674]: time reset -0.169734 s 1 Mar 11:24:29 ntpd[4676]: time reset +0.574879 s ... 1 Nov 11:28:02 ntpd[4669]: time reset +0.493571 s 1 Nov 19:54:33 ntpd[6168]: time reset +0.324889 s 2 Nov 11:56:25 ntpd[6168]: time reset +0.493251 s 2 Nov 14:09:49 ntpd[6168]: time reset +0.761453 s 2 Nov 18:57:50 ntpd[6168]: time reset +0.267648 s 2 Nov 19:19:37 ntpd[6168]: time reset +0.633949 s 3 Nov 15:04:26 ntpd[4993]: time reset +13.963114 s <=== upgrade 3 Nov 16:14:24 ntpd[4993]: time reset +126.365828 s 3 Nov 19:12:32 ntpd[5051]: time reset +42.074367 s 4 Nov 12:46:09 ntpd[5076]: time reset +22.996088 s 4 Nov 13:32:56 ntpd[5076]: time reset +393.672856 s 5 Nov 13:35:23 ntpd[5163]: time reset +351.141250 s 5 Nov 14:00:25 ntpd[5163]: time reset +318.950445 s 5 Nov 14:50:51 ntpd[5163]: time reset +0.164107 s 5 Nov 19:55:07 ntpd[5163]: time reset +27.860709 s 5 Nov 23:15:44 ntpd[5163]: time reset +436.175607 s You see that the time resets are small when I had suse 10.2, but with 10.3 they jumped in size up to almost 400 seconds.
