Date format is wrong for English (Denmark) preset

[Søren Porse]

The date format is wrong for the "English (Denmark)" preset. It should be DD-MM-YYYY, but is currently YYYY-MM-DD.

That's coming from the locale definition

$ LC_ALL=en_DK.UTF-8 locale d_fmt
%Y-%m-%d

That date format is not wrong. It's intentionally in accordance with ISO 8601.

That might very well be the case. Nonetheless, the YYYY-MM-DD date format is never used in real life, by Danes. Source: am a Dane myself and have lived here all my life.

Having expressed my disagreement with your choice of date format, I would only like to know then, how I might be able to create my own, custom date format for use in Ubuntu?
