Sure it could by having an invisible background thread occasionally call
time.monotonic(). It could even be done on the side without a thread.

Anyway, the idea of a clock is complicated:

 * the program could be stopped by a STOP signal

 * the program could be suspended from power management

 * the program could be resurrected from a virtual machine snapshot

 * the program could be migrated from a different physical machine

So, if I call

   time.sleep(86400)

and the program is suspended for 24 hours, should time.sleep() return
right after it is resumed or after another 24 hours?
