title: Convert Full Date String in javascript to yyyymmdd
body: <p>was wondering if someone could advise on I can format the following String to another String in a different format</p>
  
  <p>From this->
  var dateString = "January 8, 2013 7:00:00 PM PST"</p>
  
  <p>To This ->
  dateString = "20130108"'</p>
  
  <p>I don't mind converting this into a Date object if I have too in order to do this, but would like the final result to be a String.</p>
  
  <p>Thanks!</p>
