I've read the three solutions on How to change time display to 12h time format in Ubuntu and set my time to 24 hour in the GUI and using gnome-tweak and I've managed to change my time and date format nicely, but cannot set 24 hour clock: the "AM" is still showing. This is in spite of
"Time Format" being set to "24-hour" within the GUI, (see figure above)
Entering in the command
gsettings set org.gnome.desktop.interface clock-format '24h'
and setting within browse to org > gnome > desktop > interface > clock-format within
dconf-editor, and change the format to '24h'
How can I get the 24 hour clock format, is there some other setting that could be contradicting these three methods?
