Abstract: An arrangement in a mobile telecommunication system which has two or more base stations having transmitting elements which are each arranged to operate with a respective real-time clock and a time-comparing element. A central coordinating unit in the system is arranged to transmit a first time signal to an element arranged in the base station for receiving the first time signal. The first time information is then transferred together with a second time information to the time-comparing element. The second time information is set up by the real-time clock in the transmitting element. The first time information and second time information are placed in relation to one another and, in dependence on the relationship between these and existing criteria, for example delays and the like, the time-comparing element adjusts the real-time clock so that synchronization is carried out.
