php convert datetime to UTC

I am in need of an easy way to convert a date time stamp to UTC (from whatever timezone the server is in) HOPEFULLY without using any libraries.

Solution

  • Try the getTimezone and setTimezone, see the example

    (But this does use a Class)

    UPDATE:

    Without any classes you could try something like this:

    $the_date = strtotime("2010-01-19 00:00:00");
echo(date_default_timezone_get() . "<br />");
echo(date("Y-d-mTG:i:sz",$the_date) . "<br />");
echo(date_default_timezone_set("UTC") . "<br />");
echo(date("Y-d-mTG:i:sz", $the_date) . "<br />");

    NOTE: You might need to set the timezone back to the original as well
