Cannot change addUTCTimingSource

Created by: kisdaniel

I would like to change the default UTCTimingSource to https, but it seems to do nothing, it is stil tries to load the http time source:

 var url = "stream/live_audio.mpd";
 var player = dashjs.MediaPlayer().create();
 player.initialize(document.querySelector("#videoPlayer"), url, false);
 player.clearDefaultUTCTimingSources();
 player.addUTCTimingSource("urn:mpeg:dash:utc:http-xsdate:2014", "https://time.akamai.com/?iso");

In the manifest file there is also a https url in timesource:
