System Clock keeps drifting forward

pgb205 · 09-08-2010, 12:41 PM

the time on system clock given with 'date' command keeps moving forward about 1 minute for every hour of realtime. The box is up all the time so this is not an issue with motherboard battery. An equivalent box with the same hardwre/OS and applications doesn't have the same level of drift. I'm not sure what else this could be.
Both boxes are Centos 5.2 64-bit.

thanks for any suggestions

Is this a virtual server?

You can run as root:

Code:

ntpdate 0.pool.ntp.org
hwclock --systohc

That will set the correct time. To keep the time from drifting you can turn on ntpd.

Code:

service ntpd restart

my concern that even without ntp the time shouldn't drift that much.
what would cause it to drift this much forward?
it's not a virtual box btw.
