Issues in the output signal generation of an atomic clock ensemble and the smooth management of the time scale are considered. Special algorithms are proposed to solve the objectives, making it possible to improve the stability of the output signals against possible reference frequency signal jumps. The operation of the algorithms is demonstrated by means of numerical modeling.
