Doesn't work in IE8

[nschmoller]

The newest version (1.5.0) doesn't seem to work to in IE8 or IE7. The problem also occurs in the example.

I think the problem is with Date.now, which doesn't exist before IE9. The following code fixes this:

if (!Date.now) {
  Date.now = function() {
    return new Date().valueOf();
  }
}
