Just two miles of cold blue water, and I'm staring straight into tomorrow.
misslily Astronauts on the International Space Station use a neutral time zone to maintain a regular schedule.
misslily With all longitude lines meeting at the South Pole, scientists must choose their own time zones.

An imaginary line on the Earth's surface, running between the poles, where the calendar date changes. In 2011, Samoa skipped December 30 entirely to shift its position to the west of this boundary.
