This might just be me being overzealous with [DRY](http://c2.com/cgi/wiki?DontRepeatYourself), but it seems like we could potentially use the initial text content of `timeTillClose` to avoid the hard-coding of the number `5` in this code. That way if we ever decided to change the original HTML to use a different number of seconds, we wouldn't have to change any JS! Hooray!
