Thunderbird Time Formatting not matching system
I am running Thunderbird on Linux, using version 91.4.1 (64-bit). My OS is set to use a 12 hour clock, yet all times in Thunderbird use a 24 hour clock. I checked out the help article, and it seemed to indicate having the locale set to English (United States) in preferences should get me the 12 hour clock, but both Application locale and Regional settings locale show that option. Switching does not change anything. I tried looking in the config editor, but I was unable to locate any of the settings to change time formats mentioned in the help article.
Why is Thunderbird stuck on a 24 hour clock?
The help article I tried: https://support.mozilla.org/en-US/kb/customize-date-time-formats-thunderbird

I figured it out, I think. I was using the flatpak version of Thunderbird instead of the binary from the repos (I was trying to use the latest version). I would guess that, because flatpaks run in a container, Thunderbird couldn't tell what my system clock settings were, so it defaulted to a 24 hour time format.
After switching away from the flatpak version, the times in Thunderbird now follows the rest of my system for formatting.

what does your Linux system tell you when you query the TZ variable?

i get nothing from "echo $TZ", but "timedatectl" shows my Time zone as America/New_York (EST, -0500), and "date" shows my date and time like i expect it/would like it to if it helps, I'm using Pop!_OS 21.10, an Ubuntu based distribution
$ echo $TZ
$ timedatectl
Local time: Tue 2021-12-28 13:22:21 EST Universal time: Tue 2021-12-28 18:22:21 UTC RTC time: Tue 2021-12-28 18:22:20 Time zone: America/New_York (EST, -0500)
System clock synchronized: yes
NTP service: active RTC in local TZ: no

See if this helps. https://askubuntu.com/questions/1038952/how-to-change-time-display-to-12h-time-format-in-ubuntu
I had a look at the help article, and I've already got GNOME set in the 12h format. The only app I can see that is still showing things in 24h format is Thunderbird.
The dconf-editor tool in the article looks useful though, thanks for that.
I have the same problem. It is not global, in that my OS displays civilian (12-hour) format rather than military (24-hour) format. My Thunderbird client did the same thing to, at least until the last update which broke it. Developers: Please fix your mistake as I am not in the military and prefer Thunderbird time match my system.

Are you using Linux? This topic is about the Linux operating system and how to make it report time to Thunderbird in a 12hour or 24 hour format. Even then you would perhaps need to be using the same distribution, as not all distributions are created equal.

I'm running LinuxMint 20.3 with Thunderbird 91.* and I'm getting the same issue. Now, it was normal until I got an update. Then after that I noticed the time. Here is what I'm showing for system time. chuck@chuck-OptiPlex-3010:~$ echo $TZ
chuck@chuck-OptiPlex-3010:~$ timedatectl
Local time: Mon 2022-06-06 16:22:14 PDT Universal time: Mon 2022-06-06 23:22:14 UTC RTC time: Mon 2022-06-06 23:22:14 Time zone: America/Los_Angeles (PDT, -0700)
System clock synchronized: yes

I've read the articles tried a few things and I'm about to the point of removing it from my system and loading again. But it would be nice if there was a fix other than that. Not sure if that would help at this point. It should be noted that ALL other applications are using 12Hr format only Thunderbird is locked to 24hr. If it's getting the time from the system and the system is 12hr, sure seems like Thunderbird now has a mind of its own.
