Abstract: This invention concerns a system comprising processors (2, 3) arranged so as to receive and process data arriving at the system and containing time-indicating means (11, 17, 21) operatively connected to said processors and arranged so as to furnish time data to the processors for time-marking of the data. The time-indicating means (11, 17, 21) include a hardware clock arranged so as to generate a clock signal, and further arranged so as to receive second time data from at least one additional time reference and modify the clock signal from the hardware clock using the second time data in order to generate the first time data. The time-indicating means (11, 17, 21) are arranged so as to add to the clock signal, during the generation of the first time data, a compensation signal (??i) based on said second time data. The invention also concerns a method for time-marking data.
