def getAggregationMonthsAndSeconds(self):
return self._aggMonthsAndSeconds<EOL>
Returns the aggregation period of the record stream as a dict
        containing 'months' and 'seconds'. The months is always an integer and
        seconds is a floating point. Only one is allowed to be non-zero at a
        time.

        Will return the aggregation period from this call. This call is
        used by the :meth:`nupic.data.record_stream.RecordStream.getNextRecordDict`
        method to assign a record number to a record given its timestamp and the
        aggregation interval.

        :returns: aggregationPeriod (as a dict) where:

                  - ``months``: number of months in aggregation period
                  - ``seconds``: number of seconds in aggregation period
                    (as a float)
