I am also having the same issue. My clock is 4 hours ahead. The "Manual time adjustment" is grayed out. Occasionally my radio station presets change then the next time I use the car they are back.
Did you have the wireless car play upgrade?

Follow up... Infiniti has a software update... Brought mine in to the service department and they updated the software and all is fine now.
