Note that unlike the Windows and Linux APIs, mach_absolute_time does not do correction for frequency-scaling and 
cross-CPU synchronization with the TSC.

I'm not aware of anything else that you could use on MacOS, so your best bet is probably just to use mach_absolute_time 
and document it's shortcomings.
