Comments Displaying Wrong Date

This is very strange. I have the following code in functions.php to display the time and author of comments:

<p class="commentMeta"><?php comment_time('F m, Y');?> at <?php comment_time('G:i a T');?> | <?php comment_author_link();?> writes:</p>

But the date displayed is radically wrong. Today’s comments, for example, are listed as “August 8”. In the WP back-end the dates are correct, only on the display are they wrong.

Ideas?
