Yes, and latency is a further problem.  On some platforms timer resolution 
is good, but latency is awful.  In other words, once the timer gets 
started, it can time to very fine resolutions, but the timer takes so long 
to get started that it isn't nearly as useful as you would wish.

If you really care about a portable solution, you might want to contact the 
C Language committee people who have been trying to write a new portable 
timer spec.
