Question 1450Navigation General

The correct answer is C) 1200 GMT. The date is the same all over the world at 1200 GMT (Greenwich Mean Time) because this is the standard reference time used for international timekeeping. At 1200 GMT, the date changes simultaneously across all time zones globally, regardless of the local clock time. The other options are incorrect because 0000 GMT is the start of the day, 0000 LMT (Local Mean Time) varies by longitude, and there is always a specific time when the date changes worldwide.
