title: iOS : Specifying unix time in NSDateFormatter's format string
body: <p>I receive date in this format <strong>"/Bla(1344433014807)/"</strong> in server's response.
  1344433014807 is a number of seconds from the 1 January 1970.</p>
  
  <p>Also I have this code in my network engine that I use :</p>
  
  <pre><code>NSDateFormatter* dateformatter = [[NSDateFormatter alloc] init];
  [dateformatter setDateFormat:dateFormat];
  NSDate *date = [dateformatter dateFromString:dateString];
  </code></pre>
  
  <p><strong>Question:</strong> how can I specify correct dateFormat to get date from dateString like @"/Bla(1344433014807)/" or even is it possible?</p>
  
  <p><strong>Note:</strong> In engine I don't have access to manipulate with dateString. I can set dateFormat only.</p>
