Well, if you're willing to use an external command, you could go with date(1):

    for F in "$@"; do
        [[ -f "$F" && -r "$F"]] || continue
        DATE_ADDED_UTC=$(mdls -raw -name kMDItemDateAdded "$F")
        [[ "$DATE_ADDED_UTC" != "(null)" ]] || continue
        DATE_ADDED_LOCAL=$(date -jf '%F %T %z' "$DATE_ADDED_UTC" '+%F')
        echo "The file $F was added on $DATE_ADDED_LOCAL"
    done
