Posted date format not reflected

Question

WP3.6, Twenty Thirteen theme

No matter which Date Format I choose, the date on actual posts are shown like this:

%A %B %e%q, %Y

Note that the actual texts look like this; not even the date values (eg. 9/01/2013). Looking at content-link.php, date might be displayed by the following that I suspect is not returning a right value?

        <?php twentythirteen_entry_date(); ?>

What's wrong? Thank you.

Answer 1

I found a workaround by myself. In wp-content/themes/twentythirteen/function.php:

function twentythirteen_entry_date( $echo = true ) {
:
    //$date = sprintf( '<span class="date"><a href="%1$s" title="%2$s" rel="bookmark"><time class="entry-date" datetime="%3$s">%4$s</time></a></span>',
    $date = sprintf( '<span class="date"><a href="%1$s" title="%2$s" rel="bookmark"><time class="entry-date" datetime="%3$s">%3$s</time></a></span>',

x %4$s

o %3$s

Still, it doesn't seem to reflect the choice of the date-format setting made on wp.
