Adler combines mathematics and geography to successfully tackle a topic many kids find confusing. With simple and clear language, he introduces readers to the idea that time zones  are dictated by the rotation of the Earth. When the sun is directly overhead in one part of the world, it is midnight on the other side of the globe. The author divides the difficult material into easily digestible chunks, first tackling the Earth's division into 24 sections. He then moves on to explain the prime meridian and international date line. Finally, he explains the zigs and zags that the time zones  make on the map. Also included is a fascinating history of the advent of official time zones , necessitated by technological advances in travel and communication. Miller's  digital illustrations work hand-in-hand with the text to help youngsters grasp the concepts presented. He includes many different views of the world (planet, globe, map), laying a strong geographical foundation. Quirky details and collaged-in photos keep readers' attention. Sure to be a teacher favorite. (Informational picture book. 6-10)
