I know that a similar question has been asked at superuser.

But I tried to grep for "time reset" in my /var/log/system.log and I can't find any instance of it. In fact, I even searched in the eight archived copies of system.log (system.log.0.bz2 through system.log.7.bz2). All I found when grep'ing for the word "ntpd" are lines like these:

Feb 20 10:17:16 caspar ntpd[44498]: proto: precision = 1.000 usec
Feb 20 12:27:21 caspar ntpd[44625]: proto: precision = 1.000 usec
Feb 20 18:31:53 caspar ntpd[44625]: bind(28) AF_INET6 > <censored IPv6> flags 0x11 failed: Can't assign requested address
Feb 20 18:31:53 caspar ntpd[44625]: unable to create socket on en0 (7) for <censored IPv6>

Update #1

Following @Raolin's suggestion, I now see lines like this in /tmp/ntpd.log:

21 Feb 19:30:52 ntpd[2328]: DNS ttl 1900
21 Feb 19:30:52 ntpd[2328]: DNS minpoll 9
21 Feb 19:30:52 ntpd[2328]: DNS maxpoll 12
21 Feb 19:30:52 ntpd[2328]: DNS +iburst
21 Feb 20:02:32 ntpd[2328]: DNS ttl 4013
21 Feb 21:09:24 ntpd[2328]: DNS ttl 3507

I'm not sure if the lines containing 'ttl' means it's trying to sync.

I'm not sure if there are any log messages by default—I couldn't find any either.

One possible solution is to just enable logging. You can edit:


And add this (or something similar):

-l /tmp/ntpd.log

To the exec /usr/sbin/ntpd line in the script (the last line). Then kill the ntpd process (it will automatically relaunch) or reboot.

Answer would be more convicing if you included lines from a log file showing that your method worked. – gosmond Feb 21 '13 at 7:20
