find "${PATH} -name "*.jpg" | while read filename; do
   	exiftool "-AllDates=1986:11:05 12:00:00" "${FILENAME}";
done

exiftool "-FileModifyDate<XMP:DateTimeOriginal" \
         "-FileModifyDate<EXIF:CreateDate"       \
         "-FileModifyDate<XMP:CreateDate" \
         "-FileModifyDate<$IPTC:DateCreated $IPTC:TimeCreated" \
         "-FileModifyDate<EXIF:DateTimeOriginal" ${FILENAME}
