title: String description of NSDate
body: <p>I have the following code:</p>
  
  <pre><code>[ [NSDate date] descriptionWithLocale: @"yyyy-MM-dd" ]
  </code></pre>
  
  <p>I want it to return a date in the following format: "2009-04-23"</p>
  
  <p>But it returns: Thursday, April 23, 2009 11:27:03 PM GMT+03:00</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Thank you in advance.</p>
