PURPOSE: To attain measurement of more exact ensemble time for more completed accuracy of ensemble in an improved system which provides estimated time from the ensemble of an oscillator. CONSTITUTION: This system considers at least added time and added frequency aspect or added time and added frequency change with the lapse of time and aspects of respective oscillators of ensemble. This system considers, on respective oscillators of ensemble, the aspect of added time, the aspect of added frequency, and the aspect of added frequency change with the lapse of time. On respective clocks, a total of addition of respective aspects amounts is one, and either of 0 or a positive number can be selected. This system can be attained by using Kalman approach.
