I loaded DJI Go4 on my iPad and the dates are the same as they are on the smart controller, so it’s not just a display issue on the controller. Interesting that there are two sets of dates - one off by six years (flight records) and one off by 12 or 13 hours (photo dates).The OP has clarified to me that the issue is with a Mavic 2, the current drone, not an Inspire 1. I misread the original post. My bad guys. This issue seems to have a common denominator being it effects the Smart Controller version of DJI Go 4.
I would be interested, those of you having this problem, if the flight records are correct if you view them on another device other than the Smart Controller. It could be it’s a parsing error with the SC app
