관리자페이지 상품문의란에서 문의날짜와 답변날짜를 넣고싶은데 문의날짜는 어찌어찌 나오게 했는데 답변날짜가 어렵네요

문의 날짜는 iq_time 란걸 알겠는데 답변날짜는 어떻게 넣어줘야 할까요?

<?php
    for ($i=0; $row=sql_fetch_array($result); $i++) {
        $row['iq_subject'] = cut_str($row['iq_subject'], 30, "...");
        $href = shop_item_url($row['it_id']);
        $name = get_sideview($row['mb_id'], get_text($row['iq_name']), $row['mb_email'], $row['mb_homepage']);
        $answer = $row['iq_answer'] ? 'Y' : ' ';
        $iq_question = get_view_thumbnail(conv_content($row['iq_question'], 1), 300);
        $iq_answer = $row['iq_answer'] ? get_view_thumbnail(conv_content($row['iq_answer'], 1), 300) : "답변이 등록되지 않았습니다.";
        $iq_time = substr($row['iq_time'],2,8);

        $bg = 'bg'.($i%2);
     ?>
    <tr class="<?php echo $bg; ?>">
