          :type since: ``datetime``/``dict``
          :param since:
              Object has to be newer than this timestamp (absolute ``datetime``,
              or relative ``dict``). Valid keys for relative `since` timestamp
              dictionary are same as keyword arguments for `datetime.timedelta`
              (``days``, ``seconds``, ``minutes``, ``hours``, ``weeks``).
          :type until: ``datetime``/``dict``
          :param until:
              Object has to be older than this timestamp (for format, see the
              `since` parameter above).
          :type last: ``bigint``
          :param last:
              The number of newest objects (that satisfy all other criteria) to
              return.
          :type first: ``bigint``
          :param first:
              The number of oldest objects (that satisfy all other criteria) to
              return.
          
          :rtype: ``list``/``dict``

              A list of object description dictionaries. If ``oid`` is specified,
              a single dictionary is returned instead of a list.
