Are you sure get_avatar($comment, '128') of type false|string can be used in echo?

<div class="media-body">
	<h4 class="media-heading"><?php echo get_comment_author_link(); ?></h4>

	<time datetime="<?php echo comment_date( 'c' ); ?>">

Are you sure the usage of comment_date('c') is correct as it seems to always return null.

					get_comment_date(),
					get_comment_time()
