Filter Hook: post_date_column_time

Need to add a little something to the date column on the posts/pages page? Maybe just make the date a little bolder. It’s easy

add_filter( 'post_date_column_time', 'customize_date_column', 10, 4 );
function customize_date_column( $h_time, $post, $column_name, $mode ) {
	//$post = post object
	//$column_name = date
	//$mode = 'list' or 'excerpt'
	
	return  ''.$h_time.'';
}
