A method and a control unit are proposed for checking the performance reliability of a timer that is arranged outside of the control unit, used in particular for controlling an internal combustion engine, and that supplies time information to the control unit, further time information being generated internally in the control unit and being compared to corresponding time information supplied by the external timer. Because an internal time meter is started in the control unit and the comparison of the time information supplied by the external timer and by the internal time meter is carried out at arbitrarily specifiable points of time, a malfunction of the external timer can be determined during the entire operating time, and furthermore, a deviation can be calculated with higher accuracy.
