Javascript in Chrome

Hi everyone, This is not really a WP topic but I wonder if anyone knows the answer. I have a javascript ‘clock’ at the top of my pages that works beautifully in Maxthon, FF and IE but will not work in Chrome. It shows the correct time with every page refresh but does not continue with the time once the page has loaded. I have checked Chrome settings but all seems ok. I guess I should look for a Chrome forum but if anyone here has any ideas I would appreciate it. Thanks.
