Did you mean timer or time?  Using "man -k timer" yields "setitimer(2) -
set value of an interval timer."  It apparently provides microsecond
timers, but read the caveats carefully.  If you meant time look at ftime(3)
or getrusage(2).  As is often the case, these answers were readily found in
the manual.

Remember that Linux is not a real real-time operating system, and if you
might not enjoy great repeatability at millisecond resolution.
