title: Convert ms timestamp to NSString date
body: <p>I know a lot of iOS conversion questions have been asked before but I just can't find a way to solve my problem.</p>
  
  <p>I'd like to convert a milliseconds timestamp (i.e. 1299970800) to a correct, human readable date,  but how?</p>
  
  <p>Something like "12 Mar 2011" is enough. Thank you!</p>
