When I import videos/dngs from my DJI drone, Lightroom Classic adds 6 hours to each of the video (.mov) files creation times, and not to the .dngs. I researched this problem here and it sounds like this is a years-old problem without answers documented. Is that still the case as of Aug 2022? Now that I have discovered this bug, I do a manual time adjustment in Lightroom so my sorts will work correctly but something is wrong.
I have verified the correct capture times are recorded with the files on the drone. I am using the latest Lightroom Classic version. If I alternate taking a pic / video / pic / video, etc. with my drone, only the videos have the +6 hour time shift after import.
If Johan's comment is accurate then check the "Bug" section of the forum for a report and add your support. If you do not find one then create a new report. There is a thread in the forum with instructions how to create a"Bug report".
I do not use a drone, but if the issue exists it certainly would be a pita for me.
