Hi there. The time of the flight record refers to the take-off time of the aircraft recorded by the mobile device. Have a nice day.
I've never seen it with DJI products but I have seen it in computer apps/programs. Not sure why it happens but it shows how technology (or our programming of it) is still imperfect.
I did find DJI Tony's reply humorous though....obviously he didn't check out your video.
