We have different time zones because if we all set our clocks to the same time noon would be the middle of the day in some places, but it would be morning, evening and the middle of the night in others. Since different parts of the Earth enter and exit daylight at different times, we need different time zones.
Different time zones exist as you move from east to west (or west to east) on the surface of the earth. The farther you travel, the more time zones you'll pass through. Time zones are not something that naturally occurs. Humans came up with time zones and decided which parts of the earth are in which time zones.
