Abstract:

The report describes quartz clocks, ammonium and cesium frequency standards and other modern means for precise time determination. For example, it is noted that the use of cesium standards in combination with a quartz clock has made it possible to create a basically new time standard independent of the earths rotation. The resulting time scale is known as atomic time. The abbreviation is TA-1 its uniformity is considerably greater than that obtained from astronomical observations. The introduction of atomic standards in the time service has considerably changed their problems. The availability of these new time standards is making possible more precise study of changes in the earths rate of rotation and is yielding new information on the internal structure of the earth.
