Abstract: A method is proposed for verification of time data from a time signal modulated on a continuous carrier signal with steps to receive a first time signal with a first reference time, to receive a second time signal with a second reference time, which follows the first reference time in time, for calculation of the target time interval lying between the reference times from the time data contained in the received time signal, to determine a time interval and determine a reference time interval, using counting of periods of the continuous carrier signal within the time interval, for comparison of the target time interval with the reference time interval and to send an error signal, if the deviation determined by the comparison surpasses a stipulated tolerance value.
