Abstract :
The principle of system clock in time scale is presented. Two related propositions are proved, based on the analysis of atomic clock noise characteristics. The classical weighted average methodology is discussed in the light of the system clock principle and some drawbacks of that methodology are pointed out. A new algorithm of time scales is proposed. It uses the dynamic model of the atomic clock. A simulation is conducted, and the results are presented
