I don't know what version Glenn is building (it just says x86_74-darwin,
AFAICT), so maybe this is not useful, so just in case...

On my system it says for 'man clock_gettime'

DESCRIPTION
...
     CLOCK_MONOTONIC    clock that increments monotonically, tracking the time since an arbitrary point, and will
                        continue to increment while the system is asleep.
...
HISTORY
     These functions first appeared in Mac OSX 10.12
