When checking out T4195 I noticed that the representation of dates on the command line during key creation has not enough digits:

Wie lange bleibt der Schlüssel gültig? (0) 80y
Key verfällt am 01/04/06 13:43:59 Mitteleurop�ische Zeit

"06" means "2106" in this case, this is confusing. (Kleopatra always shows the full date with 4 digit year.)
After key creation the expiration date is shown correctly as "[expires: 2106-01-04]"
The day and month representation during key generation could be better, too, can't we use ISO format?

Additionally there is an encoding issue here with umlauts. This is on Windows cmd.
