Recommendation 1 of the 78th CIPM (1989)
Synchronization of UTC(k) and UTC
The Comité International des Poids et Mesures,
- that sorne laboratories report values of UTC(k) to the Bureau International des Poids et Mesures (BIPM) that show significant departures from UTC,
- that the close agreement of timing centres with UTC facilitates the operation of a number of systems in astronomy, geodesy, navigation and telecommunications,
- that laboratories, in consultation with the BIPM, use appropriate means to reduce existing offsets between UTC(k) and UTC to a few microseconds without making any adjustment in frequency to clocks contributing to TAI.
