<p>Apparatus for providing accurate local time for one or more timed devices that depend on such time for operation. In one embodiment, a Satellite Positioning System (SATPS), such as GPS or GLONASS (11, 13), provides the time signal information. In another embodiment, the time signal information is provided by telecommunication means (43, 45), such as a telephone, cellular telephone or similar apparatus. The local time signal is distributed by a time signal distribution module to one or more timed devices by a wire or transmission line, by radio waves, or by direct contact with an input terminal of a timed device. The time signal distribution module may be a single station, a master station for a system of timed devices, or a portable module that can be moved from one timed device to the next.</p> |
