I would like to stay with clock_gettime(CLOCK_MONOTONIC, ...) as the value isn't subjected to change when wall time is changed. Still there are chances to get wrong (non monotonic) values when NTP adjusts frequencies. Maybe some ifdef magic can be used to even use CLOCK_MONOTONIC_RAW if it is available and fall back to gettimeofday in case of older systems. The only thing would be then -lrt on the linker command line which has to be sorted out somehow. > feel like wiring up timer_get_us() too ? Will do in a v2.
