Celestial Navigation · Time — GMT from Zone Time (West)
Zone time is 1000 and your zone description is +7. What is GMT (UT)?
- A1000
- B0300
- C1700✓ Correct
- D1707
Explanation
GMT = zone time + zone description (applying the sign). 1000 + 7h = 1700. In west longitude the ZD is positive, so GMT is later than local zone time.
