Blog starting at 2

I want to display the second blog item so I have tried to use perch_blog_custom with "start" => 2 - but its displaying the first item. Can you suggest what I'm doing wrong? Thanks

My code is

<?php
    perch_blog_custom(array(
      'sort'=>'postDateTime',
      'sort-order'=>'DESC',
      'template'=>'blog/homepage_post_in_list-news.html',
      'category' => array('news'),
      'start' => 2,
      'count'=>1
    )); 
?>
