On the evening of July 1, the ship approached the date line and crossed it exactly at 23:00 (according to the time of the zone in which it was up to that moment). What date and time should be set on the ship?
The date line runs along 180 ° longitude, that is, in the middle of the time zone. In a number of places this statement is not true, but in the original concept of time zones this is so. When moving across the date line from west to east, you need to subtract 1 day from the current date, and when moving from east to west, add. Therefore, in the first case, the date and time will be June 30, and in the second – July 2. At the same time, the ship travels within the same belt and there is no need to transfer time.
