Thousands of years ago astronomers made incredible calculations about time based on the movement of the sun, moon and stars. They kept track of the hours using shadows, sand, water and flame. This book shops how the way we measure time has developed from simple sundials to atomic clocks. It explains too why navigators needed to tell the time at sea and how the invention of trains finally brought us standard time.
