Re: FreeBSD date drifts significantly

When I set it, it is absolutely correct and

the system (CMOS) date. I then reboot and -
shezam!
it's jumped 12 hours forward. Reboot again -
another
12 hour jump ... until the FreeBSD date is about 2
and
a half days beyond today's date - and the CMOS
date.

When I set up the system I said that the system
clock
is NOT set to UTC - but just to be sure, I went
back
into sysinstall and re-set the time zone the same
way
(MST - Arizona).

I suspect this has something to do with maybe the
server that is synchronizing my time; but I don't
recall how to synchronize my time with an
up-stream
server. Can't find documentation on it either.

Any pointers?


man ntpd

has your answers. my /etc/ntp.conf looks like:

server us.pool.ntp.org
server 0.pool.ntp.org
server 1.pool.ntp.org
driftfile /var/db/ntp.drift

things stay synced up tight on my machine

This is very helpful information. I have been wanting
to synchronize my date.

It didn't really stop the problem; but I ran a bunch
of test and have narrowed it down to the following -
although I cannot dependably reproduce it.

It has something to do with rebooting from windows (a
dual-boot system) straight into FreeBSD (using my boot
manager of choice: GAG.)

It seems that if I boot into windows, log in and enter
the windows time/date tool -- make no changes and
reboot into FreeBSD, the FreeBSD date will lurch
forward 10 to 12 hours. The CMOS date is still right.
It's a puzzle; but since Windows seems to be required
to duplicate this weirdness I'm not going to worry
about it -- at least until I can duplicate it without
winD'OH!s.

Thanks for the input, guys.
