Abstract

The electronic clock circuit, has a time base generator (1) such as a bistable circuit which excites a frequency divider (2) and has three NAND gates stages (N1, N2, N3). The time base frequency is demultiplied to a final frequency of one Hertz. This final frequency signal is supplied to a stepping device (3) which actuates an optoelectronic or a pointer device at every second of time. By means of a push button switch (10) the state of the first two NAND gates (N1, N2) may be change to give additional pulses to the third NAND gate (N3) and consequently actuate the stepping device (3). Correction of the indicated time may then be obtained.
