Change Thunderbird time format
To edit the Thunderbird time format on Linux, edit /usr/bin/thunderbird. Just before the line exec $MOZ_PROGRAM "$@" add one more line:
export LC_TIME=nl_NL
(or any other language of your choice)
There are probably other/easier ways to do this, but since I want this to only affect thunderbird, I prefer this method.© GeekLabInfo
