The time zones are each of the 24 spherical sectors which divide the land area. Each of them result to divide the 360º of the Earth globe between the 24 hours that invests in giving a complete revolution on its own axis.

Each time zone measured 15 degrees (360º / 24 hours = 15º). 15º = 1 hour.

The Meridian 0 (Greenwich) is taken as reference to know the time in any place in the world. Using it we add one hour for each time zone that is moved towards the east and we subtract one hour for each time zone moved toward the west.
