Customize "twentyten_posted_on" function for Date

Hi everyone!

I’m trying to customize my first www.ads-software.com blog, and I’ve got a lot of things under control. In Blogger, I found a way to customize the position of the date, as well as add styling to each element of the date – the day, month, and year.

I have no idea how to do that in the Twentyten theme though. Any help?
Do I have to adjust the coding in function.php? Or just in loop.php?

Here’s the ‘twentyten_posted_on’ function:

function twentyten_posted_on() {

	printf( __( '<span class="%1$s">Posted on</span> %2$s <span class="meta-sep">by</span> %3$s', 'twentyten' ),

		'meta-prep meta-prep-author',

		sprintf( '<a href="%1$s" title="%2$s" rel="bookmark"><span class="entry-date">%3$s</span></a>',

			get_permalink(),

			esc_attr( get_the_time() ),

			get_the_date()

		),

		sprintf( '<span class="author vcard"><a class="url fn n" href="%1$s" title="%2$s">%3$s</a></span>',

			get_author_posts_url( get_the_author_meta( 'ID' ) ),

			esc_attr( sprintf( __( 'View all posts by %s', 'twentyten' ), get_the_author() ) ),

			get_the_author()

		)

	);

Thank you for any help!
