def is_current(self):
return False<EOL>
Tests to see if the last method invoked retrieved up-to-date data.

        Simple retrieval methods do not specify errors as, generally,
        the data is retrieved once at the time this object is
        instantiated. Some implementations may provide real-time data
        though the application may not always care. An implementation
        providing a real-time service may fall back to a previous
        snapshot in case of error. This method returns false if the data
        last retrieved was stale.

        return: (boolean) - ``true`` if the last data retrieval was up
                to date, ``false`` otherwise
        *compliance: mandatory -- This method must be implemented.*
        *implementation notes*: Providers should return false unless all
        getters are implemented using real-time queries, or some trigger
        process keeps the data in this object current. Providers should
        populate basic data elements at the time this object is
        instantiated, or set an error, to ensure some data availability.
