The program reports:

          Gettimeofday() = 1094745228.671790000
           CLOCK_REALTIME=     -17032.000003664 resolution= 3648.000238936
          CLOCK_MONOTONIC=     -17032.000003664 resolution= 3648.000238936
 CLOCK_PROCESS_CPUTIME_ID=          0.000714263 resolution= 0.000000001
  CLOCK_THREAD_CPUTIME_ID=          0.000723913 resolution= 0.000000001


The HPET driver reported a 4ns tick on the timer.  Thanks,
