title: query with CURRENT_DATE returns 0 entries
body: <p>I've got such query</p>
  
  <pre><code>SELECT b.id, b.publisher_id, b.name, b.size, b.present,
         b.display, d.book_id AS download,
         b.download_date
    FROM books          b
    LEFT JOIN downloads d ON d.book_id=b.id
   WHERE b.download_date = CURRENT_DATE
   ORDER BY b.id
   LIMIT 10 OFFSET 0
  </code></pre>
  
  <p>And I've got this entry in my database.</p>
  
  <pre><code>id(bigserial) publisher_id(bigint) name(character varying) size(bigint) present(boolean) display(boolean) download_date(timestamp with time zone)
  19;1;"Attacks on and Countermeasures for USB Hardware Token Devices.rar";634764;TRUE;TRUE;"2014-06-10 08:05:28.439+00"
  </code></pre>
  
  <p>But it doesn't show the result. But today is <code>2014-06-10</code> in Windows.
  What's the problem?</p>
