Change Time and Date Format in Thunderbird

To change the way Thunderbird displays the time and date (to correspond to the British format), perform the following steps:

1. Make a backup of the existing desktop launcher file

$ sudo cp /usr/share/applications/thunderbird.desktop /usr/share/applications/thunderbird.desktop.bak

2. Edit the original file:

$ sudo vim thunderbird.desktop

3. Change the following line:

Exec=thunderbird %u

to

Exec=env LC_TIME=en_GB.UTF8 thunderbird %u

4. Relaunch Thunderbird

Or just run the command:

LC_TIME=en_GB.utf8 thunderbird &
