Thanks for your reply, johnhiler!

1) Thank you, the linked code works fine.

2) The plugin works but this is more than i need Is it not possible to place a short text with the last date/time of edit by a template tag? By the way is there anywhere a overview about available template tags?

3) Yes, i could hardcode it into the template. I don´t know how often i change the value yet. But everytime i change the value i also have to edit the template. So I wanted to avoid it.
