When I check out the chrome console I find: Uncaught TypeError: Cannot set property 'innerHTML' of null
In chrome canary I also get:
Invalid CSS property value: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,rgba(0,0,0,0.33)), color-stop(100%,rgba(0,0,0,0.75)))
and the same error as found in in standard chrome.
I believe the problem is your time() method on line 189 of script.js; there's no element with id "time".
