title: QDateTime::fromString returns invalid Date, what am I missing?
body: <p>I have some code that reads a datetime from a sqlite database, the datetime is returned as a string. when I try to convert it to a date using QDateTime::FromString it returns an invalid date. Below is the time as returned from the database and conversion. 
  Why is this failing to parse? </p>
  
  <pre><code>// -this is the value returned from the DB currentServerTime=2012-01-17 19:20:27.0
  
  QString format("yyyy/MM/dd hh:mm:ss");
  QString qCurrentServerTime(currentServerTime);
  now = QDateTime::fromString(qCurrentServerTime, format);
  </code></pre>
