Techniques of construction of atomic time scales are discussed and experiments at the National Research Council using a group of commercial cesium standards and the NRC 2.1 m laboratory cesium standard, Cs III, are described. Time scales based on the multiple standard approach are compared with the scale UTA (NRC) resulting from the periodic calibration of a secondary standard in terms of Cs III. The influence of the frequency stability of the secondary standard on the accuracy and the uniformity of the latter time scale is discussed in detail and it appears that non-uniformities of UTA (NRC) are dependent in large part on instabilities in the secondary standard. A comparison between the monthly rate fluctuations of UTA (NRC) and UTC (USNO), measured with respect to UTC (BIH), shows that UTC (USNO), which exemplifies one of the most sophisticated realizations of the multiple standard technique, is about twice as uniform as UTA (NRC). A proposal aimed at minimizing the growing complexity and expense of atomic time scale operation is made, involving the continuous use of a long beam primary cesium standard to generate a time scale possibly more accurate and uniform than existing scales.
