clocks(7) - various system timers
getitimer(2), setitimer(2) - get/set value of interval timer

see ( man -k timer ) list for some other references.

I am not sure what sort of high resolution you are refering to but maybe
these will lead you in the right direction. Bruce Evans CCd - he may
have quite a bit that could be added to this. I always find what he has
to say very enlightening.
