What are Time Zones?
Time zones are geographic regions that have the same standard time. They are based on the Earth's rotation and are defined by the difference in hours between Coordinated Universal Time (UTC) and the local time. The world is divided into 24 time zones, with each zone being one hour ahead or behind the zones on either side of it.
