Geochron, the World Wall Clock

Geochron is a dynamic display of time, day, date, and seasonal sun position everywhere on the earth.

A brilliantly colored illuminated mylar world map on an endless belt is set in motion by a precise electric clock motor, synchronous with the earth's rotation.The light pattern on the Geochron changes to match the earth's rotation to the sun, accurately reflecting rising and setting times with the changing seasons. Manual control allows display of sunrise and setting for any date. All time zones are clearly marked on the map in dark blue lines, which converge on pointers at the top of the map which indicate standard time zones and shortwave radio prefixes for that zone. Non-standard and "pocketed" zones are indicated on the map with deviations from the standard times.
