Time problem

Hi!
I have Compaq AlphaServer DS20E (here is /proc/cpuinfo)

cpu                                  : Alpha

cpu active mask            : 0000000000000003

running SuSE 7.1 Alpha edition, kernel 2.4.19 (from Linus kernel tree,
www.kernel.org), compiled with
# CONFIG_RTC is not set
System time on our machine is running late, about 20 seconds a day. Our job
is very time dependant, tolerance is 5 seconds. Problem with RTC set was
worse (about 30 sec./day).
What can I do?
