If duties are affected by the timetable, what should you use to keep time reliably?

• A. Wall clock
• B. Smartphone
• C. Digital clock
• D. Reliable Watch

Answer: (D)

When your duties are tied to the timetable, you need a timekeeping device you can rely on at all times. A reliable watch is best because it’s portable, under your personal control, and designed to run continuously without needing a network or external power source. You can check it quickly, keep it wound or charged, and compare it to the timetable at the start of duty to stay in sync throughout your shift. Other options like a wall clock, a smartphone, or a digital clock depend on location, power, or network availability, so they can become unavailable or inaccurate when you need precise timing.
