How to reload the page on time?

Question

JavaScript

Hello. There is a script. And sometimes he "hangs". The page needs to be reloaded to run. Is it possible to somehow wrap this in a function, for example, tied to a timer, which would reload the page if, say, the code freezes for more than 30 seconds.?
The script is something like this:

(function (window, undefined) { 
    var w;
    if (typeof unsafeWindow != undefined) {
        w = unsafeWindow;
    } else {
        w = window;
    }
    if (w.self != w.top) {
        return;
    }
    function start() {   }
    function check() {   }
    function get() {      }
    function  e() {    }
})(window);
