[Airport] I want to check how to read the time at the time of booking

In the case of this booking example, the departure time may be from 9:41 to 10:21 and the arrival time may be from 10:20 to 11:00. The exact time will be fixed the day before the boarding date, but you cannot specify it, so please specify a time with plenty of time.
If you cannot make the flight by arriving at 11:00, please return to the previous screen and set the time to 10:45.
