- Print clock information so we know if something is not reported correctly

from the tsc.
 - Set skipnext = 1 for yielding and preempted events so we don't show the
   event that adds us back to the run queue.  It used to be 2 so we would
   skip the ksegrp run queue addition and the system run queue addition
   but the ksegrp run queue has gone away.
 - Don't display down to nanosecond resolution for scheduling events right
   now.  This can sometimes cause a division by zero.
