Sure. And for me that means that time.hires() would give a high
resolution version of time.time(). Ie, not monotonic, but wall clock.
The question then is why time.time() doesn't give that resolution from
the start.

It seems to me we need three functions: One to get the wall clock, one
to get a monotonic clock, and one that falls back if no monotonic
clock is available. Both time.time() and time.monotonic() should give
the highest resolution possible. As such, time.hires() seems
