It should be possible to display the time (hour/minute) that a screen was loaded.

We use large screen monitors on a wall in our operations center, with a browser such as firefox constantly reloading screens or slide shows.

Sometimes the browser hangs, so to show how fresh the information is a static clock would "solve" this problem.

The flash clock is not sufficient because it is unreadable from a distance, it is not static, and - it's flash

I've attached a patch to show what we need. The patch is without translations.
