How to configure 24 hour time, instead of AM/PM, in Thunderbird 62.2.0 nd/or 62.2.2.
Presently I have created /usr/bin/thunderbird24h:
/usr/bin/thunderbird24h: #!/bin/sh LC_TIME=C export LC_TIME /usr/bin/thunderbird
and rebooted but the AM/PM time is still being used. Have I nissed something or has something changed since Fedora-20?
