title: Convert a date and time string according to UTC format
body: <p>I am having a date string <code>2012-11-21 13:11:25</code> which I get from local database. I have to convert this according to <code>UTC</code> settings and display it on a particular screen. So if its <code>GMT+05:30</code> it should be displayed as <code>2012-11-21 18:41:25</code> on the screen. How can I do this conversion. I have checked some of the questions but that didn't work out. </p>
  
  <p>I am able to get a Date object that returns something like <code>Wed Nov 21 13:11:25 GMT+05:30 2012</code>  after this I need to get the time as <code>18:41:25</code> and date as <code>11-21-2012</code></p>
  
  <p>Thanks in advance</p>
