I'm currently using Windows 7 Ultimate. I've seen that some people have full date/time info in their system tray clock like this:
However, my current system tray clock is shown like this:
I wonder how I could change the clock, but can't find any way to do so without a third party application. Maybe there's a way to hack into registry or something?

Finally I gave up with the "non 3rd party" idea and use Tclock Light to do it, this small free, portable application do it awesome :D.
