KF5 TimeZone problem

When I start the KDE4 desktop with available applications replaced with 
KF5 ones (including KDE PIM), I get this error box [attached].

I see discussion about this on the web but no real conclusion of what 
the problem is or how to fix it.

So, I am continuing to use Kalarm from KDEpim-4.14.10 (& libkdepim).  
You configure the whole package and then change to those two directories 
in the "build" directory and make and install only those two sub 
modules.  KDEpim has two dependencies, Baloo and KDEpimlibs that must be 
installed first.  You don't need the whole package for them but the 
configure script asks for it so it is easiest just to install them.  If 
this installs anything that causes a conflict, you can just manually 
remove it.

I then added the paths to the:

     /opt/kf5/etc/xdg/autostart/kalarm.autostart.desktop

file so that it would use the KDE-4 version:

     Exec=/opt/kde/bin/kalarmautostart /opt/kde/bin/kalarm --tray

{make appropriate changes if you didn't install in (or have links to) 
those "opt" directories}.

This workaround solves the problem, but it doesn't fix it.  I have been 
unable to determine what the actual problem is.  Any theories?
