Question

I want to create a form in drupal 6 that user has force to fill the fields in a limited time (eg: 10 min).

I want to handle this limit time in the server side of my code.I don’t want the user can change the time by change it’s system clock.

Is it possible without $_SESSION ?

Use a PHP session. Something like this should work:

//Set your start time when the user enters the page:
session_start();
if(!isset($_SESSION['start_time'])){
    $_SESSION['start_time'] = time();
}

//Check the current time against the start time when the user submits:
if(!isset($_SESSION['start_time'])){
    $elapsed = time() - $_SESSION['start_time'];
    $limit = 10*60; //Since time() is in seconds, multiply desired # of minutes by 60
    if($elapsed <= $limit){
        //It took less than 10 minutes
    }else{
        //It took more than 10 minutes
    }
}
