given an offset how can i convert the current time to UTC time in javascript
<pre><code>a = new Date();
Sun Apr 08 2012 16:58:03 GMT+0530 (IST)
</code></pre>

<p>Is there any way i can get the current UTC time?
I thought of getting an offset doing maths:</p>

<pre><code>b = a.getTimezoneOffset()
-330
</code></pre>

<p>then subtract, get the value:</p>

<pre><code>c = a - b
1333884483552
</code></pre>

<p>but again getting <code>c</code> as <code>a</code> to look is difficult. So the question:
<strong>How can i get the current UTC time, in javascript?</strong></p>
