A sundial is a device that tells time based on the sun's relative position. It has a triangular part that stands up from the dial, casting a shadow that points to different parts of the dial through the day. It needs to be set up for where it will be used, and daily equation of time offsets need to be manually compensated for.
The Aztecs used a combination of a solar calendar and a ritual calendar known as the tonalpohualli to tell time. The tonalpohualli consisted of 260 days, while the solar calendar had 365 days. By combining these calendars, the Aztecs were able to track time and important celestial events accurately.

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
