PHP: Convert Local Time to UTC

Question

Assume I get a string like 08/22/2015 10:56 PM and that this date/time string always refers to only one particular time zone. I need to be able to convert that to t

Answer 1

You can use DateTime, example bellow:

setTimeZone(new DateTimeZone($tz_to));
echo $dt->format($format) . "\n";

$minutes = 30;
$dt->add(new DateInterval('PT' . $minutes . 'M'));
echo $dt->format($format) . "\n";
