摘要

Time data testing device (202) comprises a time data preparation unit, a first memory unit (205) for storing first time data, a time data change determination unit for determining a change of the first time data, a time data difference determination unit for determining the difference between the stored first time data and the changed first time data, a second memory unit (206) for storing the difference between the stored time data and the changed first time data and/or the changed first time data and a testing unit. An independent claim is also included for an electronic data containing the above time data testing device. Preferred Features: The time data preparation unit is a real time clock switching circuit (203) for preparing the first time data as real time data.
