Hi all,
I've observed a system that had a wildly incorrect hardware clock (when
it was first unboxed), I ran ntpdate to sync the kernel clock but after
a shutdown and startup again it had a wacky time again.
I came across the discussion about how the hardware clock is no longer
set at shutdown[1]
The system has ntpd running
Looking at the output of
adjtimex --print | grep status
the bit corresponding to 64 / STA_UNSYNC is 0
There is a time and date page on the wiki[2] and in the manual[3],
neither of them appears to have up to date information about the way it
works with systemd or how to troubleshoot issues like this.
Monitoring it with:
hwclock -r ; date
shows that the hardware clock is running slowly, losing maybe 1s per
hour. I would have expected that if the kernel is syncing to the
hardware clock every 11 minutes then I wouldn't see such changes.
Can anybody make any suggestions or add anything to the wiki?
Regards,
Daniel
