Date and time formatting on input screens

[partnerwerk]

As a user I have the choice out of three date formatting options on the user settings page to be used in the system:
dd-mm-yyyy
mm-dd-yyyy
yyyy-mm-dd

All of these are difficult to read when you are used to German date formatting, which is dd.mm.yyyy

Is it possible to add this as a choice?

The same for time formatting: Times are shown in the system in the format hh:mm, I would prefer hh.mm.

But there is no option for time formatting, is it?
