Changing date and time between timezones

Question

I have been trying to convert between timezones a given date and time.
Code speaks more than words, so here it is:

/**
 * Returns the date and time in the n

If your stumbling on this, it can be done cleaner now with the DateTime Object.

public function convertTZ($dateTimeString, $inputTZ, $outputTZ){
    $datetime = 
        \DateTime::createFromFormat('Y-m-d H:i:s', //input format - iso8601
        $dateTimeString, 
        new \DateTimeZone($inputTZ))
        ->setTimezone(new \DateTimeZone('$outputTZ'));

    //outputs a string, if you want the dateTime obj - remove ->format
    return $datetime->format('Y-m-d H:i:s'); //output format 

}
