title: Unknown NSDate format
body: <p>I have the following string to convert to NSDate:</p>
  
  <p>2011-04-27 20:50:09.000002.</p>
  
  <p>I have the following code for the dateformatter:</p>
  
  <pre><code>  [inputFormatter setDateFormat:@"YYYY-mm-dd HH:mm:ss"];
  </code></pre>
  
  <p>but I'm unsure of what to put after the seconds.</p>
  
  <p>Keep in mind, I have multiple of these strings, with different numbers at the back.</p>
