time zone
Clock offset region
A time zone is one of the 24 longitudinal divisions of the Earth, each representing roughly one hour's difference from its neighbors, established so that local clock time corresponds reasonably to the position of the sun.
When you cross from one time zone to another, you adjust your watch forward or backward by an hour.
I'm three time zones ahead of you, so it's already midnight here.
Time zones enable coordination of schedules across global distances, though daylight saving adjustments and political boundaries create complications.
