In this book he traces the history of time through various epochs. In the beginning, time was backward looking and calendars served to mark commemorations of past events. Later, calendars became schedules oriented toward future events. In the interim, clocks were created, and hour, minute and second hands were added one-after-the-other as we found increasing value in ever smaller units of time.

With the advent of the computer, we count times in cycles per second, at a limen well below human perception. The sequence of events or activities that occur in these nano-seconds increasingly schedule the larger blocks of time in which we live. The sound of one hand clapping is Adam Smith's "invisible hand" of market forces coming in contact with a series of occurrences on silicon that exercise a control function equally ethereal.
