摘要： A local clock network (10, 12) has a reference control unit (16a, 16b) having a reference clock, processing unit and data memory. Coupled to each reference clock (16a, 16b) by a fibre optic cable (20a 1 -20a n and 20b 1 -20b n ) are a plurality of remote stations (22a 1 -22a n and 22b 1 -22b n ), typically clients desiring an accurate clock signal which is precisely and reliably synchronised with the local clock signal of other users within the network or interconnected networks. The user units (22a 1 -22a n and 22b 1 -22b n ) are in the form of a clock indicator unit which provides a clock signal for use by the internal client systems. Each network (10, 12) is a closed loop system between the associated reference station (16a, 16b) and the associated remote user stations (22a, 22b). Each reference station (16a, 16b) determines the latency associated with each remote user station (22a 1 -22a n and 22b 1 -22b n ) and generates an offset appropriate for each user station (22a 1 -22a n and 22b 1 -22b n ). Each reference station (16a, 16b) then generates a specific clock signal for each remote user station (22a 1 -22a n and 22b 1 -22b n ) on the basis of its reference clock signal adjusted by the appropriate user station offset. The local user time clocks are thus precisely synchronised to one another. A plurality of separate networks (10, 12) are synchronised by reference to their local Coordinated Universal Time (UTC) clocks, with one reference station acting as a master station.
