The analog clock is a flash object, which is something browsers are rapidly dropping support for and disabling because flash is known to present security vulnerabilities. Without knowing what browser you are using (probably Chrome?), I can't offer detailed instructions, but you'll need to have the Adobe Flash plugin installed and activated for it to function.
I know there are other means of coding an analog clock display like this, and this is probably a good time for me to explore those options and replace it with something more universally supported. Flash is dying, so eliminating the use of it here is the best thing for me to do. I believe the clock and gameroom are the only flash components used on this site.
