INFORMATION ACCURACY MANAGEMENT SYSTEM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an information accuracy management system and a recording medium capable of carrying out control of high accuracy, etc., even in the case where the accuracy of time information of a clock device itself is not high. SOLUTION: Accuracy information 1 transmitted from a radio ECU 21 side is received at step 200. Accuracy of the time of the radio ECU 21 and a telephone ECU 35 is compared with each other based on the received accuracy information 1 and accuracy information 2 of the clock device itself at step 210. Namely, it is judged whether or not own accuracy (accuracy of the clock device of the telephone ECU 35) is better. A transmitting request for feeding the time information 1 is outputted to the radio ECU 21 in order to carry out a time correction at step 220. Then time information 1 transmitted from the radio ECU 21 responsive to the transmitting request is received at step 230. The own time information 2 is corrected using the time information 1 transmitted from the radio ECU 21 at step 240.
