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 ?
