moment.js IN ember not working in IE

I have to add current date and time to my UI . I have installed ember plugin to my app moment.js but it is working in chrome but is showing invalid date in the IE.

I have added moment code in my model-

Date: function() {

return moment(new Date(parseFloat(this.get('createOn'))).toLocaleString()).format('MMM Do YYYY, h:mm:ss a');

}.property('createOn')

Any solution to make it work in IE too.
