Format date of datetime helper on ui

I always use language English, so the format of the datetime helper is fixed to english (m-d-yyyy). I want it to be western europian (d-mm-yyyy). Please disconnect the format of the helpers from the choosen language but use the choosen date format.

Understand the question but as FYI … I do not have this issue, my language is set to English GB
In the settings, one can choose the time format and not date… so I am voting too.
BTW. do also vote for your own request
