ISO8601-based custom date format in Linux Mint

Right-click the calendar widget in the panel > toggle Use a custom date format > Add %Y-%m-%d%n%H:%M% to the field below.

Seconds omitted because I don't have use for them, and %n to put the hours and minutes in a second line, so it's easier to read.

Didn't test in other Debian-based systems. And iirc changing the locale to either Danish or Japanese also works, but then the system won't be in English.

Hope this helps someone. =)

I remember having to look up the format rules to do exactly this when I first tried Mint. Astonished it's not one of the default options.

Puzzling, right? https://en.wikipedia.org/wiki/Date_and_time_notation_in_France

I didn't know about %n, but otherwise I've been using this.

I'm disappointed that my world clocks broke and only display UTC after upgrading to LMDE 7.

They're all listed if you type man date or date --help in your terminal
