JavaScript date object issue on Explorer
<p>I'm having a weird issue with Internet Explorer which is not converting a valid string date to JavaScript Date method.</p>

<p>The string is as the following:</p>

<pre><code>2011-12-26T13:55:49.377Z
</code></pre>

<p>It's working fine on Chrome and Firefox but not on Explorer.</p>

<p>This is the code:</p>

<pre><code>var now = new Date;
var call_start = new Date(call.start);
var difference = now .getTime() - call_start.getTime();
</code></pre>

<p><code>call.start</code> is valid but <code>call_start</code> is <code>NaN</code> so the Difference is <code>NaN</code>.</p>

<p>What's the problem here?</p>

<p>I really need the miliseconds here...</p>
