Format Date in a foreign language

Hi,

i need the weekday in german and want to use the CI4 Time library.

PHP Code:

use CodeIgniter\I18n\Time;

$time = Time::parse('2022-12-10');
echo $time->format('D. d.m.Y'); 


This gives me the english weekday. Is this a setting from CI or a PHP setting? In CI4 i added "de" to defaultLocale and supportedLocales but it is not working.

PHP Code:

$time->toLocalizedString('D. d.m.Y'); 


PHP Code:

$time->toLocalizedString('D. d.m.Y'); 


This is not working, because the date format string is another one. but i will try it. Then i have to change alle date strings in my app.

You can also use IntlDateFormatter::format
PHP.NET - IntlDateFormatter::format

What did you Try? What did you Get? What did you Expect?

I think CI uses IntlDateFormatter under the hood if i use the "toLocalizedString" method.
