I think it should be removed.

If you look at clock_time documentation no guarantees about resolution are given.
there is a call to get resolution, so in the best case you'd need to use
that to get a 'correct' time. It would mean 2 system calls every time, since there
is also no guarantee that the call to get the resolution will give the same
result every time.
