A device for calibration of a time-giving unit (4) in a vehicle (1) which is arranged to emit a reference time to one or more electronic units (2) comprises a means (10) designed to receive a superordinate reference time from a second time-giving unit (9, 14) of the vehicle and a contrivance (11) arranged to calibrate the first time-giving unit by causing the latter's reference time to match with the received superordinate reference time received, separately from the first time-giving unit's emission of reference time to said electronic units. |
