time and smp



from the smp faq:

7.Why does the clock drift so rapidly when I run linux SMP? 

     This is known problem with IRQ handling and long kernel locks in
the 2.0 series kernels. Consider upgrading to a later 2.1
     kernel (not garenteed to work). 

     From Jakob Oestergaard: Or, consider running xntpd. That should
keep your clock right on time. (I think that I've heard that
     enabling RTC in the kernel also fixes the clock drift. It works for
me! but I'm not sure whether that's general or I'm just being
     lucky)
