There are 24 time zones in the world, each representing a difference of one hour from the standard time zone of Greenwich, England, also known as Coordinated Universal Time (UTC). The time zones are defined by longitudinal lines that run from the North Pole to the South Pole and divide the Earth into 360 degrees.
