Hmm, this is a kext target, right?

If not (that is, you're doing this from user space) you should use mach_timebase_info, as shown in QA1398 "Mach Absolute Time Units".

<http://developer.apple.com/library/mac/#qa/qa1398/_index.html>

No, this is not a kext. And using mach_timebase_info() works fine. But I thought there would be a simpler, not-deprecated way, without worrying about integer overflows. Maybe there is none. What I really want: something to measure relative times less than a microsecond. Both NSDate and gettimeofday have only microsecond accuracy. And mach_absolute_time uses "ticks" whose value depends on the cpu. Is there some other (simple, non-deprecated) time function to use?
