Abstract: Real signal of time scale with reference to an optical clock was continuously generated for five months. The parameter of the steering entered to a phase micro stepper was determined by the prediction of a hydrogen maser frequency, which was in accordance with the frequency evaluated by an intermittent operation of an 87Sr optical lattice clock. The generated signal was compared with Universal Coordinated Time (UTC), resulting in the time difference of 8 ns after the five months. The comparison against TT(BIPM), on the other hand, showed the difference of sub-ns, which corresponds to the mean scale interval as same as the SI second in the precision below 10^-16.
