Unfortunately documentation on these functions is very sparse, only topic except usage example says that mach_absolute_time() is absolute time value for current wall clock time in units (https://developer.apple.com/library/mac/#documentation/Darwin/Conceptual/KernelProgramming/services/services.html#//apple_ref/doc/uid/TP30000905-CH219-CHDGFEFE, Handling Version Dependencies section)
