New submission from Ricardo F <rfra...@rfraile.eu>:

Finally since the release of OSX 10.12 the equivalent from the FreeBSD and 
OpenBSD "CLOCK_UPTIME" is available on Darwin under the name "CLOCK_UPTIME_RAW":

CLOCK_UPTIME FreeBSD [1]:
Starts at zero when the kernel boots and increments monotonically in SI seconds 
while the machine is running.

CLOCK_UPTIME OpenBSD [2]:
Time whose absolute value is the time the system has been running and not 
suspended, providing accurate uptime measurement, both absolute and interval

CLOCK_UPTIME_RAW Darwin [3]:
Clock that increments monotonically, tracking the time since an arbitrary 
point, unaffected by frequency or time adjustments and not increment while the 
system is asleep.


It would be useful to have it available on time module [4] for this platform.

As the behaviour is equivalent, maybe it can be assigned to the existing 
time.CLOCK_UPTIME funtion.




Thanks,
