Check the menu from the MFD (multi-function display) using steering wheel buttons to see if;
1. ... it has the "sync with head unit" option and switch this to off, or
2. ... you may see the Date/Time menu option (in the MFD) and adjust the clock from there, may have to press the R button located at the side of the roundel that houses the instrument cluster, after setting the date and time.
