What standard time should operators follow before reporting for duty?

Operators are required to adhere to the standard time shown on the depot clock before reporting for duty. This clock is synchronized to ensure that all personnel are operating on the same time schedule, which is critical for maintaining punctuality and coordination among bus operators. By following the depot clock, operators can ensure that they arrive for their shifts in accordance with established scheduling procedures, promoting efficiency and reliability in service.

The other choices do not offer a standardized basis for timekeeping that ensures uniformity among all operators. Sunrise time varies by season and location, local time can be subjective, and scheduled times from previous shifts do not provide a consistent standard necessary for operational coordination.
