Abstract
The basic idea comprised of the present invention is to decentralize the generation of time information without suffering from the cost disadvantages expectable due to use of prior art techniques necessary for synchronizing and correcting a plurality instead of only one or two of time suppliers caused by said decentralization. This is achieved by the approach not to readjust the oscillator(s), but, instead, to accept the inaccuracy of the physical device 'oscillator' but to measure its inaccuracy and to correct it with the aid of a continuos correction calculation which is advantageously done in a digital way under usage of ETS input information and system oscillator output information.
