The calculation cycle of the atomic clock rate of Bureau International Des Poids etMesures is one month, and the rate calculation result corresponding to the Julian day of the previous month is published at the beginning of each month, and the unit is ns/day. Among them, the different numbers of the serial numbers of the clocks correspond to different types of clocks, among which 35- represents cesium atomic clocks and 4x- represents hydrogen atomic clocks, these two occupy the vast majority of clock types, and there are other clock types.
