Hi, im writing a script which runs the code within a while loop for a specified "time duration" as opposed to the "number of times". 
$_current_time = time();
$_new_time = $_current_time + $_time_offset;

while ($_current_time  < $_new_time ){

        execute_attack($random_rate);

}

Im getting stuck at the while loop for obvious reasons being that $_current_time is relatively always lesser than $_new_time as the time() function updates both variables. i need the while loop to run only for the $_time_offset period. how could i better approach this. Thanks in Advance!
