Most accurate way to get elapsed time (in microseconds) on iMX6?

The gettimeofday() call returns microseconds.

Is this the most accurate method or is there a better way?


I did a bit more snooping, and tried clock_gettime(CLOCK_MONOTONIC_RAW,&t1)

to get a timestamp.  This appears to be reasonably accurate.  Does anyone have any experience

with this to agree or disagree?
