CPU timers are OK on UP machines but we don't keep the timers in sync on MP machines so if the CPU's timer is chosen as the primary timecounter it's possible for time to not be monotonically increasing because different CPU's counters may be used at different times. But the CPU's counters are otherwise one of the higher quality counters available. So, on UP machines we'll use a relatively high quality value but on MP machines we'll use a quality that should prevent the CPU's counters from being chosen.
