title: How to set date always to eastern time regardless of user's time zone
body: <p>I have a date given to me by a server in unix time: 1458619200000</p>
  
  <p><strong>NOTE: the other questions you have marked as "duplicate" don't show how to get there from UNIX TIME. I am looking for a specific example in javascript.</strong></p>
  
  <p>However, I find that depending on my timezone I'll have two different results:</p>
  
  <pre><code>d = new Date(1458619200000)
  Mon Mar 21 2016 21:00:00 GMT-0700 (Pacific Daylight Time)
  </code></pre>
  
  <p>// Now I set my computer to Eastern Time and I get a different result.</p>
  
  <pre><code>d = new Date(1458619200000)
  Tue Mar 22 2016 00:00:00 GMT-0400 (Eastern Daylight Time)
  </code></pre>
  
  <p>So how can I show the date: 1458619200000 ... to always be in eastern time (Mar 22) regardless of my computer's time zone?</p>
