POSIX* clock_gettime

This is another API specified by the Single Unix Specification and POSIX*. It offers a monotonic system clock which is not affected (for good or bad) by NTP, but the current implementation in Linux*/
glibc
does not provide better timing through this API than through
gettimeofday()
. Intel® Trace Collector does not support this API.
