In your "secondPassed" function store the remaining time in a cookie, and on the page_load of your page see if the cookie exists and if it does make its value the default remainingSeconds value. It won't stop people cheating though, as they can alter the cookie value to give themselves more time, so I'd come up with a server-side back-up too.
