THE NEW UTC TIME SIGNALS

Abstract:	Beginning January 1, 1972, the standard time signal broadcasts no longer give directly the rotational position of the Earth to an accuracy of l/10 of a second of time, as had been done previously. Instead the new UTC Time Signals may depart from the rotational position of the Earth by as much as 9/10 of a second. To retrieve the rotational position of the Earth to an accuracy of l/10 of a second, it is necessary to apply a supplementary correction DUTl which is coded into the time signal itself. Methods for using DUTl in various applications are reviewed.
