An implementation of time.monotonic() for Python 2 & < 3.3
Description
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 platform specific implementation.
