Change the_content() in Theme Thirteen

I worked with site created on Theme Thirteen and theme uses
<?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentythirteen' ) ); ?>
to get post title, date, part of content and read-more link.
But now I need to show only post date and entire post content, but I can’t find how to do that. If I try to use <?php the_content(); ?> I get the same if I use <?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentythirteen' ) ); ?>
How to get post date and entire post content in template ?
