Yes, as a matter of fact the Earth's surface is divided into 24 standard time zones�one for each hour in the day. Each zone is roughly 15 degrees of longitude wide (longitude is a measure of how far east or west a given place is on the globe; each degree of longitude is spaced 69 miles [111 kilometers] apart at the equator and narrows as it reaches the poles).
