My friend Rhabyt recommended this book: Clocks and Culture: 1300-1700, written by Carlo M. Cipolla, a professor at UC Berkeley. It's a small but comprehensive history, told with enthusiasm. Rhabyt says it's great.
Here's a description:
"How did a time-keeping device affect the growth of crafts guilds and the scientific research that led to the Industrial Revolution? Clocks and Culture is a brief history of the changes wrought by and on Europe over four hundred years due to technological advances in timekeeping and the rise of a time-aware culture."
Can't wait to read it.
