===== Change time on lock screen to 24h format =====
Navigate to the following directory:
cd /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/components
Then edit ''Clock.qml'':
sudo nano Clock.qml
Find the following line: ''text: Qt.formatTime(timeSource.data["Local"]["DateTime"])''
And edit this line to the following:
text: Qt.formatTime(timeSource.data["Local"]["DateTime"], "hh:mm:ss")
Remove '':ss'' to just display hour and minute. Finally reboot.
