title: Date operations in HQL
body: <p>I want to get expired entities from table using HQL. Something like that:</p>
  
  <pre><code>select id, name from entity_table where date_creation + 10_minutes &lt; current_time()
  </code></pre>
  
  <p>I cant get how to do that with HQL. I DONT want to make extra-queries, process date in java code an so on. This must be done on HQL level.</p>
  
  <p>Can you please help me?</p>
