Feature

Is your feature request related to a problem? Please describe.

dd/mm/yyyy and mm/dd/yyyy date formats can be mistaken for the other, meaning they are both equally unworkable. I usually end up going for Canadian formats to get nice yyyy-mm-dd dates, but I have a feeling it could cause problems in the future.

Describe the solution you'd like

A "programmer standard" formats option, meaning

• metric measurements
• sensible date and time formats
  • ISO 8601 for formal dates 2020-07-23 00:00:00
  • RFC2822 for informal dates or dates that may require day-of-week Thu, 23 Jul 2020 00:00:00

Existing work

Not in format-pickers that I've been able to find, but the en_DK locale was supposedly created for this purpose.

Describe alternatives you've considered

Currently I use Canadian formats, when it comes to locales people commonly go for en_IE (English, Ireland).
