Time Zone
Standard time zones could be defined by geometrically subdividing the Earth's spheroid into 24 lines. The local

the zone to the other (east vs. west) would be at most 1/24 of the sky. Most of the 25 nautical time zones
(specifically UTC−11 to UTC+11) are indeed defined this way, and are 15° of longitude wide. An hourly zone in
the central Pacific Ocean is split into two 7.5°-wide zones (UTC±12) by the 180th meridian, part of which
coincide with the International Date Line.
