I need help with this.. I want to be able to keep track of how long a user is 'Logged' into my site. So far i only can get seconds. I subtract logged in time from logged out time and i want days, hours, minutes, seconds, ect.. If anyone has any sugestions it would be greatly apreciated.

Well, minutes = 60 seconds, hours = 60 minutes, and so on. You can just record in seconds and calculate it when you display it.

If you're using php, something like this ought to work.

http://www.php.net/manual/en/dateinterval.format.php

php:

<?php

$january = new DateTime('2010-01-01');
$february = new DateTime('2010-02-01');
$interval = $february->diff($january);

// %a will output the total number of days.
echo $interval->format('%a total days')."\n";

// While %d will only output the number of days not already covered by the
// month.
echo $interval->format('%m month, %d days');

?>

Look at the DateTime constructor if you're calculating from a unix timestamp.
