A time signal repeater, capable of selectively relaying standard time radio signals having different modulation frequencies and correcting the time based on the plurality of standard time radio signals without changing a radio correction clock side, including an antenna portion capable of receiving a standard time radio signal by a set resonance frequency, an oscillating circuit outputting a signal having a frequency of the received standard time radio signal in synchronization with the standard time radio signal received by the antenna portion, at least one frequency conversion circuit converting the frequency of the output signal of the oscillating circuit, a receiving circuit receiving as input the standard time radio signal received by the antenna portion and correcting a time of an internal clock according to a time code included in the received radio signal, a transmission circuit generating a time radio signal including a time code based on the internal clock based on the output signal of the oscillating circuit or the signal converted in frequency by the frequency conversion circuit at the time of transmission, and a selecting circuit receiving as input the output signal of the oscillating circuit or the signal converted in frequency by the frequency conversion circuit to the transmission system circuit, and a time correction system using the same. |
