title: UIDatePicker change locale
body: <p>I am trying to change locale for UIDatePicker like this:</p>
  
  <pre><code>  picker.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
  </code></pre>
  
  <p>It is working, but after setting locale the picker does not meet the system settings of time format. I mean 24hr/(AM/PM). What I am doing wrong?</p>
