if ($calc($ctime - $ctime($gettok(%info, 4-5, 32)) >
7) { echo -s it's more than 7... }
If it's 7 hours and not 7 seconds, use
25200 (= 7*60*60), you can think of appropriate values for 7 days etc
You can display the time between both by typing $duration($calc($ctime - $ctime($gettok(%info, 4-5, 32))
