The front of the building at 38 Neponset Ave., Foxboro, MA has a large beautiful sundial. At any time of day, one can read the sundial like any other to see the "sun time". If one looks at the sun dial at noon, one can read the date. The gnomon is angled towards the southeast. If you stop at the guard desk at the building, the guard/s some times have a pamphlet with history and details about the sundial that you may read. Note that "sun time" and "human clock time" often do not match. http://www.thefreedictionary.com/gnomon
