How to show seconds in menu bar (for 10.6.8 Snow Leopard)?

Hi everyone.

I used to have the "seconds" running and being shown in the menu bar after setting it to View as Digital in my previous Mac running 10.5 Leopard. Can I somehow have this same feature too on my current 10.6.8 Snow Leopard? I only can display the current hour and minute.

Thanks in advance...
