Yeah, but this is *freebsd*-questions, so telling the OP how to fix
a Linux box is not very coherent.
You could well be exactly right on the diagnosis of the problem though:
the CMOS clock on the motherboard can either be set to run UTC or it can
be set to the local wall-clock time. The first (UTC) is preferred by Uni=
x
machines, the second by Windows. FreeBSD will cope with a CMOS clock
set to run using the local wall clock time in order to play nice on
multi-boot systems, but you have to tell the system it's operating in
that mode.
To change the setting, run /usr/sbin/tzsetup and when asked about the CMO=
S
clock on the first screen, choose 'Yes' if your machine runs FreeBSD alwa=
ys
or 'No' if you occasionally boot into Windows. Then choose your local
timezone from the menus. If, after doing that, there is a zero length fil=
e
/etc/wall_cmos_clock then you have set your system to use a CMOS clock se=
t
to wall clock time. See adjkerntz(1) for the full story.
After running tzsetup, either restart ntpd to force your machine to step
the clock a long way to sync with the server, or set the date/time manual=
ly
as Greg described upthread.
Cheers,
Matthew
