title: Will the MySQL datetime format work with SQLite and PostgreSQL?
body: <p>In MySQL you enter dates (<code>datetime</code> field) in the format <code>2009-10-16 21:30:45</code>. Which makes it simple to insert times into the database.</p>
  
  <pre><code>$date = date('Y-m-d H:i:s', $timestamp);
  </code></pre>
  
  <p>Will this format work with SQLite and PostgreSQL? If not, what format do they use?</p>
