|Abstract:||An integrated time scale has as primary data unit of duration (time interval) defined by atomic standards according to the definition of the SI second. The availability of more than one atomic standard allows for averaging, thereby improving the performance of the time scale with respect to each of the atomic standards (clocks). The measurement of time differences between the different clocks is at the core of a time scale. A novel approach to the measurement of time differences has been developed at NIST and will be compared with the present commercial state-of-the-art.|
