Time left with unix time()

[Mutley]

I have a variable that contains a 12 figure unix time ($oldtime). This updates to the current time every 2 hours.

 

What I wish to do with this, is display the time left... before it resets again, so it's counting down from 2 hours to 0, in which it then gets reset and it starts counting down all over again.

 

How would I do this?

 

Kind Regards,

Nick.

$timeleft = ($oldtime + (60 * 60 * 2)) - time();

<?php
$diff = time() - $oldtime;
?>

You need to add 2 hours to the old time in order to actually see when it'll update.

So:

 

<?php
$diff = time() - ($oldtime + 7200);
?>

 

Thanks for the speedy replies! I shall test it out.

No, use mine.  You have the subtraction in the wrong order.
