Excerpt not showing

Hi everyone,

Im trying to display the excerpt on the main page of my blog. Which you can see here : http://hutchcreative.co.uk/rod/blog/

I have added what I know to be the needed code but I cant seem to get it to work.

Here is my php pulling in the excerpt

<time datetime="<?php esc_attr_e( get_the_time( DATE_W3C ) ); ?>"><?php the_time( get_option( 'date_format' ) ); ?></time>
	<h2 class="post-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>

	<?php if ( has_post_thumbnail() ) : ?>

	<!-- figure -->
	<a href="<?php the_permalink(); ?>" class="post-figure">

		<!-- image -->
		<?php the_post_thumbnail(); ?>

	</a>
	<!-- end: figure -->

	<?php endif; ?>

	<!-- info -->
	<div class="post-info">

		<?php if ( has_excerpt() ) : ?>

		<?php the_excerpt(); ?>

		<?php endif; ?>

	</div>
	<!-- end: info -->

Here is my functions code:

add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

function sbt_auto_excerpt_more( $more ) {
return ' ...';
}
add_filter( 'excerpt_more', 'sbt_auto_excerpt_more', 20 );

function sbt_custom_excerpt_more( $output ) {return preg_replace('/<a[^>]+>Continue reading.*?<\/a>/i','',$output);
}
add_filter( 'get_the_excerpt', 'sbt_custom_excerpt_more', 20 );

Thanks!
