I've tracked down a weird bug when importing images on my Mac. When my OS X time zone is set to UTC, all of my images are dated 1/1/1970. When I set it to a time zone like JST, the date becomes correct. The dates are affected on my RAW files after they are imported. In other words, when I change to UTC, all of the dates become 1/1/1970. When I change the time zone, images imported in the past become correct.
However, if I process an image using Capture One and convert RAW to jpg, the bad date is fixed and doesn't revert when I change the time zone.
This occurs if I copy the files from the memory directly or if I use Image Capture to import the images.
Has anyone else had this problem? I guess most people don't have their computers set to UTC...
