I have a P3P and a P4P, and use an ipad mini 2. I have had no issues with the date format. Recently, I installed Litchi and flew a few times with it. I noticed the exif data showed the year of my photos and videos to be 1951. I flew with the DJI 4 app, and noticed the same issues. The date on the ipad is correct, and the date in the DJI 4 app for my flight records is correct. But the date in the exif data is still 1951. I formatted my SD card and flew again. Same thing happens. The day, month, and time are all correct, just the year is off.
