Time Zone is a Term to describe the local time of a Region or a Country. The local Time within a Time Zone Map is described by its offset (difference) from Coordinated Universal Time (UTC). It is the world’s time standard. UTC time changes 1 hour forward and backward corresponding to a 1-hour difference in mean solar time for every 15 degrees east or west of the prime meridian (0° longitude) in Greenwich, London, United Kingdom. The offset is expressed as either UTC- or UTC+ and the number of hours and minutes.
