So I have followed the online instructions on how to change the date and time format from the American system to the German one (1st screenshot with the settings). If I want to set the date and time in an issue in JIRA, the date and time format is still the American format with Sunday being the first day and the full date format being yy.MM.dd (2nd screenshot).
My browser's language is also set to German. I have noticed that the date and time is in English, not in German.
How can I solve this problem?
Edit: We're using next gen projects.
