Description Daniel Rusek 2024-02-23 11:08:17 UTC

Found this issue during the Fedora 40 test days. The installed Fedora Workstation 40 system seems to always have a 12-hour format set, even if I selected a 24-hour one during the installation.

Reproducible: Always

Steps to Reproduce:
1. Install the Fedora Workstation 40 using latest nightly iso.
2. Set the time format to a 24-hour one during the installation.
3. Check what is the time format in the installed system.

Actual Results:  
The installed Fedora Workstation system seems to always have a 12-hour format set.

Expected Results:  
The installed Fedora Workstation system has its time format correctly set.

Comment 1 Fedora Blocker Bugs Application 2024-02-23 11:12:12 UTC

Proposed as a Blocker for 40-final by Fedora user asciiwolf using the blocker tracking app because:

 The installed Fedora Workstation 40 system seems to always have a 12-hour format set, even if I selected a 24-hour one during the installation. This is not correct and should be fixed.

There's no release criterion for this, I don't think. It doesn't really seem like something important enough to block release, to me.

What anaconda's intending to do is let you set a time *zone*, not a time format. Well, it's capable of three things: setting whether the hardware clock is set to UTC or local time, configuring NTP, and setting a timezone. What it specifically does to configure those is:

* Write out /etc/adjtime (to set the hardware clock offset)
* Enable chrony and write a configuration file for it (to configure NTP)
* Create a /etc/localtime symlink to the appropriate file in /usr/share/zoneinfo (to set the timezone)

it does nothing at all to indicate a time *display format* preference based on the timezone, and never has.

What actually changed here, I think, is just that GNOME effectively changed its default display format from 24 hour to 12 hour (while trying to make it possible to set a correct default per locale): https://gitlab.gnome.org/GNOME/gsettings-desktop-schemas/-/merge_requests/55

Since then, however, someone realized the original goal could be met more cleanly by setting the default back to 24h and just adding a US English "translation" to 12 hour:
https://gitlab.gnome.org/GNOME/gsettings-desktop-schemas/-/merge_requests/75

so when we get that in Fedora, GNOME's default should be back to 24hr display for all locales except en_US.

https://bodhi.fedoraproject.org/updates/FEDORA-2024-06d5306b7d should fix this, let me know if not.
