Abstract
In disseminating time, National Metrology Institutes have to ensure that time information received by the users is traceable and uncertainties are evaluated. This paper describes two time distribution systems developed at PSB-a synchronised digital clocks-cluster system, and an automated computer time distribution system. Results of evaluation show that the uncertainties of a few tens of millisecond for both are achievable.
