As the earth turns, the sun hits different parts at different times. Consider sunrise. When the sun rises at 6 a.m. in New York, it's still dark in Chicago, Denver, and Los Angeles. When the sun rises in New York, it's about to set in eastern Asia. If all of the world used the same time, half of the world would go to bed when the sun came up and go to bed when it set.
