text: Q:
  
  Wordpress get post date
  
  I am using shortcode to display blogroll on my main static page.
  It displays title and up to N characters of the excerpt. 
  However, I have no idea how can I get post date to show up next to the title. 
  Is get_the_date function the correct one to use? How to implement it?

  <?php
  
  function getblogposts($atts, $content = null) {
     extract(shortcode_atts(array(
        'posts' => 1,
     ), $atts));
  
     $return_string = '<h3>'.$content.'</h3>';
     $return_string .= '<ul>';
     query_posts(array('orderby' => 'date', 'order' => 'DESC' , 'showposts' => $posts));
     if (have_posts()) :
        while (have_posts()) : the_post();
      $return_string .= '<li><a href="'.get_permalink().'">'.get_the_title().'</a>';
      $return_string .= '<div class="excerpt">' . get_the_excerpt() . '</div></li>';
  endwhile;
     endif;
     $return_string .= '</ul>';
  
     wp_reset_query();
     return $return_string;
  }
  function new_excerpt_more( $more ) {
      return ' <a class="read-more" href="'. get_permalink( get_the_ID() ) . '">Continue reading</a>';
  }   
  add_filter( 'excerpt_more', 'new_excerpt_more' );  
  
  function custom_excerpt_length( $length ) {
      return 20;
  }
  add_filter( 'excerpt_length', 'custom_excerpt_length', 100 );
  ?>
  
  A:
  
  Yes. You could use get_the_date(). The important thing is use it within the loop (between while(have_posts() and endwhile;. 
  You could use
  echo get_the_date();
  
  OR
  the_date(); //without echo
  
  Another thing that you really really should consider is to NOT use query_posts().  Why? It's not easy to answer (it basically could mess up other queries), but take a look at https://wordpress.stackexchange.com/questions/50761/when-to-use-wp-query-query-posts-and-pre-get-posts.
