On ntp1, on which ntpd was last restarted 25 days ago on the 2nd, I got
464 today (which has two hours to go). Not 464 lines (since there are
multiple), 464 sets of lines:

rlaager at ntp1:~$ grep "ntpd.*this fuzz" /var/log/daemon.log | wc -l

On ntp2, which I restarted a day or two ago:
rlaager at ntp2:~$ grep "ntpd.*this fuzz" /var/log/daemon.log | wc -l
