Dear mailman community,

with the help of you I was able to set up a new mailman3 environment (a big THANK YOU!!! :-)):

OS: Ubuntu 24.04-LTS mailman: GNU Mailman 3.3.10 (Tom Sawyer) Python: 3.12.3 (main, Feb 4 2025, 14:48:35) [GCC 13.3.0] Method: Python Virtual Environment Installation

My configuration files are placed in the following directory: /etc/mailman3

• gunicorn.py
• mailman.cfg
• settings.py

The environment is up and running: A list for testing is set up and mails are transfered (and archived) using the test-list - successfully... :-)

Looking at the thread overview of the list (in Hyperkitty archives) I realized that the shown date format is unusual (for Germany), like: Do Mai 22, 3:57 nachm. (meaning: Thu May 22, 3:57 p.m.) I would prefer a format like: 22-05-2025 15:57:24

So I tried to reconfigure this setting in settings.py according to this URL: https://docs.mailman3.org/en/latest/config-web.html#configure-postorius-hype... In settings.py I set DATETIME_FORMAT to 'd-m-Y H:i:s' but the format did not change. (After changing settings.py I initiated a restart of mailman3 and mailmanweb)

I also set USE_L10N to False as suggested in Django-Docs: https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-DATETIME_FOR... My /etc/mailman3/settings.py is parsed - as far as I can say because changing USE_I18N to false (in /etc/mailman3/settings.py) switches date to English as this is my locales-setting on Ubuntu... Nevertheless the format stays the same (in this case: Thu May 22, 3:57 p.m.)

How can I adjust the date format (in the discussion boxes) at the thread overview page (url: https://my-domain.de/archives/list/test-list@lists.my-domain.de/)?

Any hint is appreciated!

Thank you very much and kind regards

 Christian
