title: Get NSDate from NSDate adjusted with timezone
body: <p>I have a NSDate object. Let's say it represents "1-10-2011"</p>
  
  <pre><code>NSDate *date = [df dateFromString:@"2011-10-01 00:00:00"];
  </code></pre>
  
  <p>That date translates into "2011-09-30 22:00:00" because of my timezone.</p>
  
  <p>Question: How do I get a new Date object representing "2011-10-01 00:00:00" in my local timezone?</p>
