Display seconds in addition to hours and minutes on the Clock

How would I go about getting the clock on my iPhone to display the seconds beside the minutes?

I have looked at Settings → General → Date & Time, but it only allows me to choose a Time Zone, Set the clock automatically or toggle 24-Hour Time.

Is there anything I can do to cause the clock to display seconds in addition to minutes and hours?

In the default, non-jailbroken OS? I don't think so.

In the status bar on a jailbroken iPhone? Yes. It's called StatusBarSeconds.

If you look at the icon for the Clock app on your home screen it has a second hand. For most cases this is sufficient for me.
