The ITU Radiocommunication Assembly considering a)that Recommendation ITU-R TF.1011, Systems, techniques and services for time and frequency transfer, includes various dissemination/comparison methods involving the use of instrumentation time codes and signals for local and long-distance time transfer;b)that Recommendation ITU-R TF.583, Time codes, addresses other forms of time codes used between pieces of equipment via hardwired or other types of connections; c)that time codes and metrological signals used for the dissemination or comparison of time and frequency signals via hardwired or other means are not sufficiently standardized for reference or use;d)that the increasing capability of modern time transfer systems by satellite or other means will require commonality in measurement accuracy and precision.
