List of child pages in a template

[D.O.]

Hi again GetSimplers,
I was wondering if it is possible to add the date of publication of these codes. I tried with "pubDate" but it gives a date too long. I would like something simpler as 12/01/2013.
Any help?

<?php
echo "<ol>";
$submenu=getChildren($id);
$menuArray=array();
foreach ($submenu as $menuitem) {
echo "<li><a href='?id=";
echo getPageField($menuitem,url);
echo "'>";
echo getPageField($menuitem,'puDate');
echo " - ";
echo getPageField($menuitem,'title');
echo "</a></li>";
}
echo "</ol>";
?>
