System time isn't accurate

Hello all. Does anyone know what causes a computer's system time to be horribly inaccurate?

My computer's time is always ahead. It eventually overlaps real time and just keeps on going.

Even if I set it to the correct time it eventually trucks on ahead.

Should I replace the MoBo battery?

I had the problem with an Amd64. It is resolved with kernel 2.6.15. There is a patch available here.

A work around is to add this to the kernel line in Grub:

Code: Select all

disable_timer_pin_1

Thank you, I'll give it a try. Think I'll start with adding that line to Grub.

Just to make it clear, edit the /boot/grub/menu.lst and change the kernel line of an entry like this:

Code: Select all

title           Debian GNU/Linux, kernel 2.6.14-2-k7
root            (hd2,0)
kernel          /boot/vmlinuz-2.6.14-2-k7 root=/dev/hdc1 ro
initrd          /boot/initrd.img-2.6.14-2-k7
savedefault
boot

to this:

Code: Select all

kernel          /boot/vmlinuz-2.6.14-2-k7 root=/dev/hdc1 disable_timer_pin_1 ro
