title: How To Use Epoch Time With Highcharts Series Data?
body: <p>I'm trying use epoch time dates in my series data. The array looks like this:</p>
  
  <pre><code>data:[ [1324857600,205.4],[1324771200,208.7],[1324684800,205.4]. . .]
  </code></pre>
  
  <p>The points display fine, but the date labels on the x-axis and tooltip are all set to 16 Jan 1970 (the beginning of epoch time!).</p>
  
  <p>If I do a bunch of string-fu I can produce an array that looks like this:</p>
  
  <pre><code> data:[ [Date.UTC(2011, 11, 26),247.7],[Date.UTC(2011, 11, 25),245.5] . . .]
  </code></pre>
  
  <p>When I do it this way the date labels on the x-axis are correct.</p>
  
  <p>I've tried using the dateTimeLabelFormat option and it formats the date correctly - it's just that when I try to use millisecond values all I get is 16 Jan 70.</p>
  
  <p>Any ideas? I'd rather work with milliseconds than jump through all the hoops to produce "Date.UTC(2011, 11, 26)."</p>
  
  <p>Thanks!</p>
