remove permalink from comment date

My theme uses this as part of its comment template:

$largs = array(
'style'             => 'ol',
'avatar_size'       => 70,
'reply_text'		=> 'Reply',
'type'				=> 'comment'
);

<ol class="commentlist"><?php wp_list_comments($largs); ?></ol>

This results in the date of each comment (which appears under the author) being a permalink for the comment. How do I make it so the date is just plain text with no permalink?
