Overview: Time is a slippery concept, as shown by the number of terms we have developed for different types of it: Sun Time, Zone Time, Civil Time, and Sidereal Time, just to name a few. Looking at a Pocket Sundial (a predecessor of the pocket watch) from the time when Chebeague Island was just being settled lets us look at the nature of time and how it has been measured over the centuries.
