Build a date string from those variables. Use the DateTime Object and use its functions to do what you would like such as $dateTime->diff(new DateTime("now")) and read up on DateInterval to see how to get back what'd you like.

EDIT: This assumes you have PHP 5.3.

mktime

$time_diff = mktime($hour, $min, $sec, $month, $day, $year) - time();

Will give you the difference in seconds. You can use that to display it however you want.

Use mktime to convert into UTC and then use simple maths to calculate differences.
