title: Convert ISO 8601 to a different ISO 8601 format using MomentJS
body: <p>Is there a way for a format like this:</p>
  
  <blockquote>
    <p>2003-09-25T14:00:00.000+1000
    or
    2003-09-25T14:00:00.000+1100</p>
  </blockquote>
  
  <p>To be converted like this</p>
  
  <blockquote>
    <p>2003-09-25T14:00:00.000Z</p>
  </blockquote>
  
  <p>Without using manual and only using MomentJS. I also want to know what +1000 or +1100 means. </p>
