        """
        Returns a clip playing the content of the current clip but
        skips the extract between ``start_time`` and ``end_time``, which can be
        expressed in seconds (15.35), in (min, sec), in (hour, min, sec),

        if they exist.

        ----------

        start_time : float or tuple or str
          Moment from which frames will be ignored in the resulting output.

        end_time : float or tuple or str
