On Time: How America Has Learned to Live by the Clock
by Carlene E. Stephens and The Smithsonian Institution

An illustrated history of the ways Americans have measured used, and thought about time over the past 300 years.

Have you ever wondered who came up with time zones, or why we adjust our clocks at daylight saving time? This entertainingly written, generously illustrated book, drawn from a popular exhibit at the Smithsonian's National Museum of American History, provides the answers to these and dozens of other questions about time. On Time showcases unusual timepieces from the museum's collection such as Helen Keller's pocket watch and the earliest bedside alarm clocks, and brings to life some of the lesser-known characters and events that have shaped the way we think about time today. With over 175 full-color illustrations with captions.
