Upon compulsorily equipped vessels which are required to have an accurate clock in the radio room, how frequently must this clock be adjusted and be compared with standard time?
• Radio regulations for compulsory-fitted vessels (SOLAS/GMDSS context) • Requirements for an accurate time source used for radiotelegraphy/radiotelephony logs and distress procedures • The meaning of standard time and why frequent comparison is important for safety and logging
• Think about how often radio operators need precise time when making official log entries, position reports, and handling potential distress traffic. • Consider whether the regulation is likely to require very frequent checks (for high accuracy) or allow longer intervals (for practicality during a watch). • Relate the options to common watch schedules (e.g., 4-hour watches) and think about what interval would reasonably ensure accuracy without being excessive.
• Check in the relevant radio or SOLAS regulations how often an "accurate clock" in the radio room must be checked against standard time. • Verify whether the required interval is tied to radio watchkeeping periods or is simply a maximum allowed time between corrections. • Confirm that the requirement is "at least" as frequent as the specified interval, not just a recommendation.
