Protobuf type transit_realtime.TripDescriptor

 A descriptor that identifies an instance of a GTFS trip, or all instances of
 a trip along a route.
 - To specify a single trip instance, the trip_id (and if necessary,
   start_time) is set. If route_id is also set, then it should be same as one
   that the given trip corresponds to.
 - To specify all the trips along a given route, only the route_id should be
   set. Note that if the trip_id is not known, then stop sequence ids in
   TripUpdate are not sufficient, and stop_ids must be provided as well. In
   addition, absolute arrival/departure times must be provided.

hasStartTime

public boolean hasStartTime()

optional string start_time = 2;

 The initially scheduled start time of this trip instance.
 When the trip_id corresponds to a non-frequency-based trip, this field
 should either be omitted or be equal to the value in the GTFS feed. When
 the trip_id correponds to a frequency-based trip, the start_time must be
 specified for trip updates and vehicle positions. If the trip corresponds
 to exact_times=1 GTFS record, then start_time must be some multiple
 (including zero) of headway_secs later than frequencies.txt start_time for
 the corresponding time period. If the trip corresponds to exact_times=0,
 then its start_time may be arbitrary, and is initially expected to be the
 first departure of the trip. Once established, the start_time of this
 frequency-based trip should be considered immutable, even if the first
 departure time changes -- that time change may instead be reflected in a
 StopTimeUpdate.
 Format and semantics of the field is same as that of
 GTFS/frequencies.txt/start_time, e.g., 11:15:35 or 25:15:35.

hasStartDate
