high res timestamps and SMP

From: Chris Friesen

We have a requirement to have high-res timestamps available on SMP systems.

Assuming that we are running identical cpus, is a sync-up at boot time enough to give usable time values, or do I need to do force periodic re-syncs?

We're currently looking at MIPS, x86 (Xeons), and PPC.

Thanks,

Chris
