Or if he needs better resolution, mach_absolute_time(), which is well documented at <http://developer.apple.com>.
<<SNIP>> OK, the best documentation I've found for this is at http://developer.apple.com/qa/qa2004/qa1398.html and I whipped up a quick test program to ensure I knew what I was doing with it. Now my question concerns accuracy; I know that mach_absolute_time() resolves to one nanosecond, but what is the accuracy? Is there a way to tell what the accuracy is from the mach_timebase_info struct? E.g., the greatest common denominator between numer and denom is the accuracy of the clock in nanoseconds? This won't affect my current code, but I'd like to stick it into my own documentation so whenever I reuse this code I know what I'm getting in to.
