title: Joda: get local milliseconds of specific timezone
body: <p>I never would believe that this could amount to being such a hassle. I am trying to make a clock that always displays the local time in specific timezones.</p>
  
  <p>My laptop is currently set in GMT0 timezone (UK).</p>
  
  <p>I want to get the milliseconds of the timezone "Europe/Stockholm".</p>
  
  <p>So let's say it's 17:00 here in the UK I would like to get the milliseconds corresponding to 18:00 which would be the Swedish time.</p>
