Your voyage planning indicates you will arrive at a waypoint in longitude 49°16.3'E at 0947 ZT on 3 March 1988. How should this date be entered into an AMVER report?
• ZT (Zone Time) vs UTC/Zulu time and how to convert between them using the ship’s zone description (ZD) based on longitude • Standard AMVER date–time group format (day–hour–minute, time zone indicator, and month) • How longitude 49°16.3'E relates to the ship’s likely time zone (ZD) on standard time-zone boundaries
• First, decide what the local zone description (ZD) would be for a ship near 49°E using 15°-per-hour time zones. Is the ZD plus or minus, and approximately what whole number? • Next, convert 0947 ZT on 3 March to the equivalent UTC/Zulu time and date using that ZD. Does the day change, or stay the same? • Then, compare the resulting date–time group with the four choices: which one both matches the correct UTC time/date and uses the proper AMVER format for DTG?
• Confirm whether AMVER reports require UTC/Zulu time, not local ZT, when entering dates and times • Check that the day and hour are consistent after converting from ZT to UTC using the correct ZD for about 49°E (no fractional hours in AMVER) • Verify which option has the correct structure: DDHHMM + time-zone indicator + month (MAR), with the time-zone letter in the proper place.
