8.5 Real-time clock
A real-time clock is used for time measurement. If there is a permanent connec-
tion between ECU_PWR of the controller and the vehicle battery, the real-time
clock will continue to run for a certain period of time even when the controller is
switched off. The real-time clock has no automatic daylight savings time function.
The JCM-501-E01 has a built-in battery with a service life of at least 10 years.
