Shift photo Date Taken

You shot the same moment on a phone with the correct clock and a professional camera whose date was hours off. Date Taken Shifter moves photo Date Taken by a fixed amount. Match clocks fills that amount from those two photos: Right date is the phone shot, Wrong date is the pro-camera shot. Press Use this shift to load amount and unit - it does not write tags yet. Keep the phone photo off the Rename List so GO only fixes the pro-camera files. JPEG uses EXIF Date Taken; PNG uses PNG Date Taken. Need Title / Keywords / Copyright instead?
