Abstract

A timing device comprises an oscillator a time base, a time display device and a control device intermediate between the oscillator and the display. In addition, it comprises a pickup for low-frequency pulses radiated by a conventional television receiver, and a treatment circuit having one input connected to the pickup, and one output connected to a means for regulation of the control device, for producing rate regulation and/or resetting.
