Celestial Navigation · Time — GMT from Zone Time
It is 0930 zone time at a vessel in zone description +5. What is the corresponding GMT?
- A1430✓ Correct
- B0430
- C1430 the previous day
- D1130
Explanation
Apply the zone description to zone time to get GMT: 0930 + 5h = 1430 GMT. The +5 zone (West longitude) is five hours behind Greenwich, so GMT is later than local zone time.
