 Some systems have APIs but not implementations: for example QNX and Haiku
 have the interval timer APIs but not the functionality.
 
+In pre-Sierra macOS (pre-10.12, OS X) clock_getres(), clock_gettime()
+and clock_nanosleep() are emulated using the Mach timers; as a side
+effect of being emulated the CLOCK_REALTIME and CLOCK_MONOTONIC are
