In recent years, with the improvement of the performance of pulsar observation equipment, especially the operation of China’s FAST, the precision of millisecond pulsar timing observations has been continuously improved. The quantity, quality and timeliness of observation data have also been significantly improved, providing strong data and technical support for the establishment and application of pulsar time. Pulsar time and atomic time have complementary advantages. An experimental platform for pulsars to control the cesium clock is established using the cesium clock and related time-frequency equipment in National Time Service Center of the Chinese Academy of Sciences, and IPTA dr2 data. Research on steering the cesium clock by the single millisecond pulsar is carried out based on J0613-0200 steering a cesium clock. Up to now, the experimental results meet the expectation of a single millisecond pulsar steering a cesium clock, showing the feasibility of a pulsar driving an atomic clock. The integrated time scale obtained from the experimental system maintains the advantage of the cesium clock stability.
