Some older distros have the tz files in /usr/lib/zoneinfo instead of /usr/share/zoneinfo.  And who knows what else other distros do!  This code scares me (the old code especially so, why is it calling zic?), we're making all sorts of assumptions about the underlying system that we can't be sure of and changing things that could break the users system.  Personally, I think the distros need to take care of this side of things by providing a script for us to call.  I think most distros do have different command line tools to do it, but finding and maintaining them all would be a nightmare.  Perhaps we need to install and call a script kde-set-timezone which the distros can then modify to call their own tools?

The symlink points to the right location after each save. Launching the module again, it shows the correct timezone, as previously saved.
