PROBLEM TO BE SOLVED: To provide a time signal repeating installation capable of selectively repeating standard time wave different in modulation frequencies. SOLUTION: An antenna part 201 capable of receiving standard time wave signals at a set resonance frequency, a PLL circuit 207 outputting a signal S207 having a frequency of wave signal resonating with a reception wave signal, a frequency conversion circuit 208 converting the frequency of the output signal of the PLL circuit 207, reception system circuits 202 to 206 correcting internal clocks to the time corresponding to the time code which the reception wave signal includes, transmission system circuits 206, 210 to 212 producing and transmitting time wave signals including the time code based on the internal clocks on the basis of the output signal of the PLL circuit 207 or the signals frequency- converted by the frequency conversion circuit 20, and a selection circuit 209 inputting the output signal of the PLL circuit 207 or the frequency-converted signals to the transmission circuits according to the selection signals SLC are provided. |
