Abstract : The paper is a discussion of the following phases of the study of the non-uniformity in the rotation of the earth according to the data of astronomic observations: (1) Determining the changes in the velocity of the earth's rotation. These changes may be detected only by way of comparing the scale of the Universal Time (TU), which is determined by the earth's rotation, with any other more regular time scale. (2) Determination of the scale of atomic time. The scale of atomic time (TA) is based on the mean atomic standard which is obtained by way of averaging the readings (integrated frequencies) of the atomic standards of the world's specific laboratories. (3) Determination of the scale for the International Time. The scales of International Time (TI) are deduced from the astronomical determination of time, which are carried out at a number of special observatories, the Time services. (Author)
