It’s really very simple to convert times in different timezones using the following function.
function dateTimeConversion($datetime,
$timezone="Europe/London") {
$date = new DateTime($datetime, new DateTimeZone("UTC"));
$date->setTimezone($timezone);
return $date->format("Y-m-d H:i:s");
}
As you can see, it takes 2 arguments, $datetime which is a time string and a $timezone which is a timezone to convert to.
A usage example would be:
echo dateTimeConversion("2012-05-01 17:09:58");
