Include “Date and time” in mini-loop …

I’m using this code on my index.php file:

[code]printf ("

• %s

", $np->ID,$np->post_title);
[/code]

from http://codex.wordpress.org/Creating_a_Static_Front_Page

the result is here: http://www.damn.be (recent articles)

It displayes a list of the most recent posts made on the weblog. I would like to include the date and time in that list when a post was made …
