monotonic
~~~~~~~~~

This module provides a ``monotonic()`` function which returns the
value (in fractional seconds) of a clock which never goes backwards.

On Python 3.3 or newer, ``monotonic`` will be an alias of
``time.monotonic`` from the standard library. On older versions,
it will fall back to an equivalent implementation:

+-------------+--------------------+
| Linux, BSD  | clock_gettime(3)   |
+-------------+--------------------+
| Windows     | GetTickCount[64]   |
+-------------+--------------------+
| OS X        | mach_absolute_time |
+-------------+--------------------+

If no suitable implementation exists for the current platform,
attempting to import this module (or to import from it) will
cause a RuntimeError exception to be raised.
