And one other niggling little problem springs to mind as an
afterthought:
5. I set the system to use the 24-hour clock in the installer,
but KDE uses the AM/PM format. Ugh! I have the digital clock on
the KDE Panel set to 24-hour format, but konsole and elsewhere
shows AM/PM. In the regional settings, I had to change the time
to Canada (iu_CA), which has kind of solved the problem, but it
is still not universal fix, since Korganizer still shows AM/PM
time :-( Has anyone solved this?
