"For thousands of years, mankind has been fascinated with the science of measuring time. Even our earliest ancestors needed to know how long the daylight would last, and how long it would be before the buffalo returned. This book tells the story of our obsession with time, and our increasingly accurate ways of measuring it."--Back cover.
