When duties are tied to the timetable, you must have a dependable time source you can rely on at all times. A reliable watch is ideal because it stays with you, is under your control, and doesn’t depend on network signals or building clocks that might be unavailable, out of sync, or powered down. Keeping your watch properly set and cross-checking it against the timetable ensures you meet scheduled times, windows, and duties accurately and avoid timing errors that could lead to violations. Other options have potential drawbacks: a fixed digital or wall clock may not be accessible when you’re on duty, and a smartphone can be restricted, may auto-adjust to the wrong time, or run out of battery, making it less dependable for on-duty timekeeping. So a trustworthy, on-person timepiece is the best choice for maintaining accurate time when the timetable affects your duties.
