People communicating across two different parts of the globe often use Greenwich Mean Time. There are four time zones in the continental United States. They are Eastern, Central, Mountain, and Pacific. Alaska is an hour behind Pacific Time and Hawaii is two hours behind Pacific Time. Almost every nation uses this system of measuring time, but China does not have time zones.
China extends across five times zones, but the country has a single time zone.
