@ -168,11 +168,11 @@ The module defines the following functions and data items:
The name of the underlying C function used to get the clock value.
.. attribute:: is_monotonic
.. attribute:: monotonic
``True`` if the clock cannot go backward, ``False`` otherwise.
.. attribute:: is_adjusted
.. attribute:: adjusted
``True`` if the clock can be adjusted (e.g. by a NTP daemon), ``False``
otherwise.
