The proposal contains:
The ITU Radiocommunication Assembly,
considering
a) that the World Administrative Radio Conference, Geneva,
1979, allocated the frequencies 20 kHz ± 0.05 kHz, 2.5 MHz
± 5 kHz (2.5 MHz ± 2 kHz in Region 1), 5 MHz ± 5 kHz, 10
MHz ± 5 kHz, 15 MHz ± 10 kHz, 20 MHz ± 10 kHz and 25 MHz ±
10 kHz to the standard-frequency and time-signal service;
b) that additional standard frequencies and time signals
are emitted in other frequency bands;
c) the provisions of Article 26 of the Radio Regulations;
d) the continuing need for close cooperation between
Radiocommunication Study Group 7 and the International
Maritime Organization (IMO), the International Civil Aviation
Organization (ICAO), the General Conference of Weights and
Measures (CGPM), the Bureau International des Poids et
Mesures (BIPM), the International Earth rotation and Reference
system Service (IERS) and the concerned Unions of the
International Council of Scientific Unions (ICSU);
e) the desirability of maintaining worldwide coordination
of standard-frequency and time-signal emissions;
f) the need to disseminate standard frequencies and time
signals in conformity with the second as defined by the
13th General Conference of Weights and Measures (1967);
g) the desirability of maintaining a relationship between
a uniform time scale (UTC) and the time defined by the
rotation of the Earth (UT1);
h) that the complexity of the variability of the Eartht's
rotation currently limits the accuracy with which the
difference between the two types of time scales can be
predicted to a few tenths of a second one year in advance;
i) that the International Earth rotation and Reference
system Service provides updated data relating the two time
scales daily to users;
Which part of that didn't you understand ?

Never attribute to malice what can adequately be explained by incompetence.
