The following is an example from ntpd.log

14 Apr 07:22:25 ntpd[1048]: synchronized to 10.0.0.5, stratum 1
14 Apr 07:22:25 ntpd[1048]: time reset +0.231004 s
14 Apr 07:23:35 ntpd[1048]: synchronized to 10.0.0.5, stratum 1
14 Apr 07:39:33 ntpd[1048]: time reset +0.318457 s
14 Apr 07:39:33 ntpd[1048]: kernel time sync disabled 0041
