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`` or ``GetTickCount64`` | +-------------+----------------------------------------+ | 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.
