It was a bit random across the different suites.  CoreMark uses
clock_gettime(CLOCK_REALTIME, ...) which is a wall clock with NTP
adjustments.  EEMBC uses clock() which is a lower resolution wall
clock.

I was quite impressed with how steady the process clock was under
different CPU loads.  It doesn't seem to round up or down to a
scheduler tick either which is nice.
