To make it work edit /etc/environment (e.g. sudo emacs /etc/environment) and add the following line to it:
LC_TIME="en_GB.UTF-8" Save the file, log out and log in again. You can check that the variable has been successfully set by opening a terminal and typing: echo $LC_TIME which should return: en_GB.UTF-8 Now start Thunderbird again and hopefully all will be well. I know it is annoying to have to do this but maybe the bug should be better addressed by the creators of distributions, who fail to set LC_TIME as a default in /etc/environment. -- Thunderbird's date format not changed easely https://bugs.launchpad.net/bugs/312483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
