Set file date from exif-date for files in $ORIG_DIR.
- Directory for original images. Defaults to $TARGET_DIR/orig.
Linux computers typically use a hardware clock set to UTC, while the clock of digital cameras is set to local time. After copying the files to hard-disk, file-date and exif-date (DatetimeOriginal) usually differ. This module sets the file-date to the same value as the date in the exif-data.
