title: select all records created within the hour
body: <pre><code>startTimestamp &lt; date_sub(curdate(), interval 1 hour)
  </code></pre>
  
  <p>Will the (sub)query above return all records created within the hour? If not will someone please show me a correct one? The complete query may look as follows:</p>
  
  <pre><code>select * from table where startTimestamp &lt; date_sub(curdate(), interval 1 hour);
  </code></pre>
