EST to UTC conversion in PHP
<p>I am trying to create a function that will convert any date and time in EST to a UTC timestamp (I do not mean the current timestamp, but rather a specific date and time).</p>

<p>The function must take into account the DST (Daylight Savings Time) for that given date.</p>

<p>I have tinkered with gmdate with no results.</p>

<p>The result should look like this:
20060415T180000Z    (180000 being 6pm and 00 seconds)</p>

<p>Any ideas?</p>
