Errors
Sequential stop_time_update times are not increasing E022 1 error
stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.
Sample errors
- trip_id 60000640 stop_sequence 7 departure_time 07:13:00 (1773036780) is less than previous stop arrival_time 07:15:00 (1773036900) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 3 errors
Within the same stop_time_update, arrival and departures times can be the same, or the departure time can be later than the arrival time - the departure time should never come before the arrival time.
Sample errors
- trip_id 60000640 stop_sequence 4 departure_time 07:12:00 (1773036720) is less than the same stop arrival_time 07:15:00 (1773036900) - departure time must be equal to or greater than arrival time
- trip_id 60000640 stop_sequence 7 departure_time 07:13:00 (1773036780) is less than the same stop arrival_time 07:20:00 (1773037200) - departure time must be equal to or greater than arrival time
- trip_id 60000951 stop_sequence 6 departure_time 07:53:00 (1773039180) is less than the same stop arrival_time 07:54:00 (1773039240) - departure time must be equal to or greater than arrival time
