time and date keep changing

valemon · 2009-10-09 11:11:20

It started happening a week or so ago. Every time I boot the time is changed. I set the date from the bios but arch shows the time wrong. Also because of this I sometimes get problems during bootup because the partition looks like it was last mounted in the future. Can anyone help me out?

Did you try to put the NTP daemon in your rc.conf, and base you system clock on NTP?

Not really, I 'd like not to use internet to get my clock set, rather get a solution the time keeps changing.

Can you paste your rc.conf?

Aside from possible hardware failure, automatic time adjust could be wrong. Try:

cat /var/lib/hwclock/adjtime
0.026639 1255063716 0.000000
1255063716
UTC

The first field should be a rather low value. If not, delete /var/lib/hwclock/adjtime and reboot.

If this does not help, make sure your hardware clock is set right (see: man hwclock). Make sure your current system time displays right and then issue (as root):

hwclock --systohc

Finally (or beforemost) check the HARDWARECLOCK setting in /etc/rc.conf. Does it match your system (either "UTC" or "localtime")?

BTW: This problem comes up often. Just search the forum.

Thank you for the help. Deleting /var/lib/hwclock/adjtime did the trick

I have the same problem for some time, no idea why. I'm using openntpd only when there is need of it, for example after Windows messes up the date. Thanks for the tips guys!

Heh, I just saw the subject (time and date keep changing) and thought that is supposed to happen. We can not have time standing still!

be aware that an empty bios battery also could cause an time problem, then the time will be reset every bootup

Arch Linux
