Thanks for the explanation.  So, I have the KDE-4 Plasma-Desktop running 
and the KDE-4 "ktimezoned" running, but KF5 "Kalarm" apparently didn't 
manage to find use it when I started KDE.  From what I have read, 
apparently, it isn't starting when KF5 "Kalarm" starts up.  The 
"Ksysguard" doesn't report it as running so it apparently doesn't run 
all the time; perhaps only when requested and KF5 "Kalarm" isn't 
requesting it in the way that will cause it to run.

Apparently, in KDE4, this is an on demand service which just isn't there 
in what I have installed of KF5:

Type=Service

X-KDE-ServiceTypes=KDEDModule
X-KDE-Library=ktimezoned
X-KDE-DBus-ModuleName=ktimezoned
X-KDE-Kded-autoload=true
X-KDE-Kded-load-on-demand=true

But, it could be called through DBus in KF5, just the same if the code 
was still there.
