You gonna format it with your PC? What settings are you gonna use? Let us know about the results...Hmmm... I just switched SD cards. The one with the incorrect readings was a SanDisk 64 Mb card. It may be one that was intended for Android phones and tablets. The new card is a 32 GB SanDisk Extreme, and all the video I've shot with it has the right time and date stamp. Interesting. I'm going to do a full (long) format of the 64 GB card to see if that fixes it.
I've was using beta but they released the full version yesterday. Works great.
So I've had an issue similar to what those above have mentioned. My P4P camera files are consistently 14 hours behind the actual time. After double checking to make sure all the date time settings on my iPad were correct (and after confirming that I could reproduce the problem with my iPhone as well), I decided to do some testing. I have 3 micro SD cards at my disposal:
SanDisk Ultra 64 GB, SDXC
SanDisk Extreme Plus 64 GB, SDXC
Panasonic 16 GB, SDHC (stock card that came with the drone)
I inserted each card into my P4P (confirming all firmware and software is up to date), formatted each card within the DJI GO 4 app, and then took a 5 second video and a still photo on each. I found that both SanDisk cards continued to write time stamps that were 14 hours off while the Panasonic card reported the correct time.
Remember that all three card were freshly formatted in the P4P itself. I opened up all three cards in Disk Utility on my Mac and discovered that the SanDisk cards had been formatted to ExFat while the Panasonic card was formatted FAT-32.
My best guess here is that this problem stems from a combination of the way that the P4P treats formatting for SDHC cards vs SDXC cards, and then how the drone writes files to ExFat formatted cards in general. To further test this idea, I manually formatted the Panasonic card to ExFat and inserted it into the P4P. I was greeted with a "format suggested" warning, but was still able to record a file. Sure enough, when formatted as ExFat, the Panasonic card wrote files with the same 14-hour discrepancy. Formatting that card again within the drone reset it back to FAT-32 and eliminated the problem. By the same token, I then manually formatted one of my SanDisk cards to FAT-32 on Mac, inserted into the drone, and lo and behold, it recorded files with the correct time.
So to conclude (until DJI fixes this), to avoid this problem, either only use SDHC cards (32 GB or less) or manually format your SDXC cards (64 GB and higher) to FAT-32 on your computer, and then avoid manually formatting those SDXC cards within the drone itself.
Hope that helps anyone else who has encountered this issue.
