Clarify "system-wide" in docs for time.monotonic() #102740
Description
The documentation for time.monotonic() currently states:
Changed in version 3.5: The function is now always available and always system-wide.
I didn't know what system-wide meant, and so propose expanding the documentation to:
Changed in version 3.5: The function is now always available and always system-wide, that is, the clock is the same for all processes on the system and the reference point does not change after start-up time.
Or anything equally enlightening. This would make it clear, that among other things, the delta may not be valid across reboots.
