EOS 5D Mark IV Date Battery

Does the 5D Mark IV have a Date battery?

It has an internal component (I believe it is a capacitor ) that will retain date/time when the main battery is removed, but it is not user replaceable. Internal charge is maintained by main battery and will remain charged for a period of time when the main battery is removed.
