Exported files from Photos show wrong created date in Finder
It's been a while since I last backed up the photos on my phone and I'm running into some issues. The last export I made from Photos was in January, and I dragged all of the photos into a folder on an external harddrive. Looking back at that folder in Finder, every one of the dates were correct. Meaning, they display the Created date the photo was taken, not when the files were put into Finder. I didn't do anything to those files other than organize them into folders, I didn't change any of the information or metadata.
Now, no matter how I export images/videos from Photos, the Created date is always the exact time I did the export, or even 2-3 days ago. I've taken 2,000+ photos since January, it's a huge inconvenience not having them organized by date. I don't know why this worked for me just a few months ago. When I import photos from my camera's SD card, Finder always displays the Created date as the date the photo was taken, so I don't understand why it can't do the same for my phone.
I was running on OS High Sierra, then just today updated to Mojave, thinking that maybe it was a bug that had been fixed, but I'm still having trouble.
macOS Mojave (10.14)
