Hi all,
While scanning my logs for something unrelated, I came across this
message from ntpd (note that I have ntpd_flags set to '-v' in
/etc/rc.conf.local):
2019-10-21T02:03:50.143Z despair ntpd[57871]: adjusting local clock by 5.579152s
I found it weird, because the machine had been up for almost three
weeks by then - normally, there's some clock adjustment after boot and
once it's OK, ntpd only adjusts the clock frequency.
I searched all logs and found the following:

(here things alternate between adjusting clock and adjusting frequency
40 times in 22 days).
So from 6.4-current, back in October 2018, there was indeed one or two
'adjusting local clock' after boot, followed by a bunch of 'adjusting
clock frequency'. However, since the update to 6.6-beta end of
September, ntpd is regularly adjusting the local clock.
Is anyone else seeing this? Could it be a sign of broken hardware or
is the battery of my RTC dead?
Thanks,
Paul
