title: Calculating remaining time?
body: <p>I have a time that was generated by like so:</p>
  
  <pre><code>SimpleDateFormat dateFormatUCT = new SimpleDateFormat("yyyy-MM-dd HH:mm");
  dateFormatUCT.setTimeZone(TimeZone.getTimeZone("UCT"));
  
  String deadline = dateFormatUCT.format(new Date());
  </code></pre>
  
  <p>I've now got this as a string called deadline. I want to get the current date time again later and compare if the deadline has passed or not. If its not passed I want to calculate how much time is remaining. Is there a good in-built way of doing this already bearing in mind that the data is now a String? </p>
  
  <p>TIA </p>
