We will have a short downtime on Friday, starting at 2023-03-03T17:00:00Z as we merge with the Fedora Discussion site. We expect this to take no more than 3 hours. When this is complete, all links (including https://discussion.fedoraproject.org/) will redirect to the new category on the merged site.
As I do understand the plugin Discourse uses to display time and date is always entered in UTC. It should show your local time/time_zone if you have the locales correct configured.
If you click on it you get some alternative time_zones displayed included UTC (UTC|Friday, March 3, 2023 5:00 PM).
