271. On 5 May your 1300 ZT DR position is LAT 25° 16.0' S, LONG 12° 30.0' W. You are on course 012° T at a speed of 14 knots. What will be the zone time of sunset at your vessel?

Determine the zone time of sunset by obtaining the local mean time (LMT) of sunset from the Nautical Almanac using the vessel's latitude and date, converting LMT to Greenwich Mean Time (GMT) by accounting for longitude, and then calculating zone time (ZT) using the zone description.
