code: def GetTimeStops(self):
      
      return [(st.arrival_secs, st.departure_secs, st.stop) for st in
              self.GetStopTimes()]
docs: Return a list of (arrival_secs, departure_secs, stop) tuples.
  
      Caution: arrival_secs and departure_secs may be 0, a false value meaning a
      stop at midnight or None, a false value meaning the stop is untimed.
