    //Get the output event list (should be empty)
    EventList& output_el = outputWS->getEventList(i);
    //and this is the input event list
    const EventList& input_el = inputWS->getEventList(i);

    //Perform the filtering
    input_el.filterByPulseTime(start, stop, output_el);

  //Now filter out the run, using the DateAndTime type.
  outputWS->mutableRun().filterByTime(start, stop);
