Bad TimeInterval dates are being created

CesiumJS
1

When I try creating a TimeInterval, the stop dates are somehow always being set to -4713-11-24T12:00:00Z. And depending on how I construct the TimeInterval, the start time is either correct or also
-4713-11-24T12:00:00Z. I added the regular Javascript Date stuff to the code below as a sanity check.

Code:

    var jsStart = new Date();
    var jsEnd = new Date(jsStart);
    jsEnd.setHours(jsStart.getHours() + 2);
   
    console.info("start/end: " + jsStart + "/" + jsEnd);
    console.info("start/end iso8601: " + jsStart.toISOString() + "/" + jsEnd.toISOString());
   
    var julianStart = new Cesium.JulianDate.fromDate(jsStart);
    var julianEnd = new Cesium.JulianDate.fromDate(jsEnd);        
    console.info("start/end julian: " + julianStart + "/" + julianEnd);
   
   
    var interval = new Cesium.TimeInterval({
        start: julianStart,
        end: julianEnd
    });
    console.info("interval 1: " + interval.start + " / " + interval.stop);
   
   
    var interval2 = new Cesium.TimeInterval(julianStart, julianEnd);        
    console.info("interval 2: " + interval2.start + " / " + interval2.stop);

Console output:

start/end: Mon Sep 08 2014 17:02:53 GMT-0400 (Eastern Standard Time)/Mon Sep 08 2014 19:02:53 GMT-0400 (Eastern Standard Time)

start/end iso8601: 2014-09-08T21:02:53.517Z/2014-09-08T23:02:53.000Z

start/end julian: 2014-09-08T21:02:53.5169999999998254Z/2014-09-08T23:02:53Z

interval 1: 2014-09-08T21:02:53.5169999999998254Z / -4713-11-24T12:00:00Z

interval 2: -4713-11-24T12:00:00Z / -4713-11-24T12:00:00Z

Am I doing something wrong? Why would the method of creating the interval produce different results?

So, I obviously had a brain fart with the end: date param in the first method of creating a TimeInterval. Using the correct stop param fixes that first set out output. But why does the second set, using the Cesium.TimeInterval(julianStart, julianEnd) fail?

Fixed code:

The TimeInterval constructor requires parameters to be passed using an object literal in all cases. It does not accept start and stop as two separate parameters. This was a change in b30.
