Metrological traceability between USNO and NIST timescales will be made available in a new weekly publication of UTC(USNO)-UTC(NIST) time differences as well as via the BIPM
Since the unit of mass is only available at the BIPM
, it must be disseminated to the rest of the world through a series of comparison calibrations involving national prototypes.
Since the situation for realization of the SI-metre has changed because of the introduction of new techniques for absolute frequency measurements (5), (6), it was decided at the 11th meeting of the Consultative Committee for Length (CCL, 2003) at the BIPM
to close the K10 comparison and to initiate a new key comparison (BIPM

Al Kuwari further pointed out that Qatar boasted of having one of the biggest metrological laboratories within the region, bigger than Saudi Arabia and the UAE, and planned to join the International Bureau of Weights and Measures popularly known as BIPM
in the future.
Locations that desire to be incorporated in UTC must have precision clocks and must follow rules established by BIPM
for calculating and reporting the clock data.
