<?php
function time_stamp($session_time)
{
$time_difference = time() - $session_time ;

$seconds = $time_difference ;
$minutes = round($time_difference / 60 );
$hours = round($time_difference / 3600 );
$days = round($time_difference / 86400 );
$weeks = round($time_difference / 604800 );
$months = round($time_difference / 2419200 );
$years = round($time_difference / 29030400 );

// Seconds
if($seconds <= 60)
