I'm guessing these are coming from MySQL... If so, you can subtract the two in MySQL much easier/faster than PHP... http://mysql.com/ If not: $s = mktime(substr($Start, 8, 2), substr($Start, 10, 2), substr($Start, 12, 2), substr($Start, 4, 2), substr($Start, 6, 2), substr($Start, 0, 4)); $e = mktime(substr($End, 8, 2), substr($End, 10, 2), substr($End, 12, 2), substr($End, 4, 2), substr($End, 6, 2), substr($End, 0, 4)); $delta = $e - $s; At this point, it boils down to the question -- Will it ever be, like, *DAYS* instead of hours, or, more importantly, *MONTHS*? Because as soon as you get into "months" or larger time units, it gets complicated... Until then, you can divide by 60, or 60*60, or 60*60*24 to get the number of minutes, hours, days respectively... -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
