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,
Alex
