title: Momentjs timezone - getting date at time in specific timezone
body: <p>I am attempting to create a date from a UTC base in a user's specific timezone, in this case "America/Los Angeles" using momentjs/momentjs timezone. However, I'm not getting the results I expect:</p>
  
  <pre><code>var tempDate = moment(1448841600000); //moment("2015-11-30"); //monday 11/30 in UTC
  var adjustedStart = moment.tz(tempDate, "America/Los_Angeles");
  adjustedStart.hour(9);
  adjustedStart.minute(30);
  console.log("adjustedStart in milliseconds:" + adjustedStart.valueOf());
  </code></pre>
  
  <p>The console output is 1448875800000 which is 11/30/15 9:30AM in UTC/GMT, I was expecting 1448904600000 which is 11/30/15 9:30AM in Pacific Coast time. How can I translate this start date to the right time in the user's timezone?</p>
