Instruction

Good! You can also sort results by time:

SELECT
  code,
  arrival_time
FROM route
ORDER BY arrival_time DESC;

Have you noticed that time and date data work very similarly?

Exercise

Show the code and arrival_time of all routes that arrive before 4:00 PM. Order them by arrival time, with the earliest time first.
