title: Am-time-ago with timezone
body: <p>I am trying to display the time ago in an angular.js app with angular-moment, moment, and moment-timezone.  I got everything to work however the time is 6 hours off for someone in Spain.  Which is 6 hour time difference from where I live.  I want the time ago to be uniformed for every person in the world.  When I change the timezone it doesn't seem to do anything and I couldn't find any documentation on how to add the timezones.  Unfortunately all of the times in the database are configured to the servers timezone.  Here's my attempt </p>
  
  <p>view.html: </p>
  
  <pre><code>&lt;table class="table"&gt;
      &lt;tbody&gt;
          &lt;tr ng-repeat="d in data"&gt;
              &lt;td&gt;&lt;span am-time-ago="d.date"&gt;&lt;/span&gt;&lt;/td&gt;
          &lt;/tr&gt;
      &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>app.js:</p>
  
  <pre><code>var arcs = angular.module('arcs', ['ui.router', 'ngMaterial', 'ngMdIcons', 'angularMoment']);
  
  $.getJSON('bower_components/moment-timezone/data/packed/latest.json', function(data) {
      moment.tz.add(data['zones']);
      arcs.constant('angularMomentConfig', {timezone: 'Europe/Amsterdam'});
  });
  </code></pre>
  
  <p>index.html:</p>
  
  <pre><code>...
    &lt;script src="bower_components/moment/moment.js"&gt;&lt;/script&gt;
    &lt;script src="bower_components/angular-moment/angular-moment.min.js"&gt;&lt;/script&gt;
    &lt;script src="bower_components/moment-timezone/moment-timezone.js"&gt;&lt;/script&gt;
    &lt;script src="bower_components/moment-timezone/moment-timezone-utils.js"&gt;&lt;/script&gt;
  ...
