Currently Thunderbird displays time in AM/PM mode.
How can I change it to 24h mode?
$ locale |grep LC_TIME LC_TIME="en_US.UTF-8"
Ok, solved it:
1) Make sure you have the locale you need, can't say which you specifically need but when you know you create it like this (using en_DK.utf8)
2) To make sure this locale is in effect for thunderbird you add it to the script that starts thunderbird, so first find that script:
2a) find the right script
In my case: /usr/bin/thunderbird
2b) add locale to the script (I use the editor geany):
Add this in the beginning of the script (I just put at the very beginning):
Just want to add this:
EDIT: as pointed out by pl1nk A better solution would be to NOT touch the /usr/bin/thunderbird script and instead create the script '/usr/local/bin/thunderbird' with this content
make sure it's executable
Then check if it's being used to start thunderbird:
should respond with this:
Now thunderbird can be started as before.
