Class scrlttr2 Warning: \date changes the internal \LaTeX date only.
(scrlttr2)              You should note that this changes the default
(scrlttr2)              value of variable `date' only as long as nobody
(scrlttr2)              uses `\setkomavar` to change the content of
(scrlttr2)              variable `date'.
(scrlttr2)              Therefore, usage of `\setkomavar' is recommended
(scrlttr2)              to change the letter's date on input line 6.
