It's indeed a "use before it's built", because when I run try to build it again (on the same build dir) it works. A clean build, however, reliably reproduces this error, even without using "-j" make option.

> Originally I wanted to port KTimeZoned 1:1 to Qt5/KF5, but then I found out that all the stuff KTZD was doing was added in QTimeZone, that includes reading correct system files/env variables to obtain the timezone and returning the proper system zone (KTZD did all this by itself). It also doesn't need to parse the timezone files itself or watch for their changes as QTimeZone objects are not stored.

Fedora or Suse, but also by Debian in conjunction with /etc/timezone) for changes and if it detects a change, it checks if the new timezone is really different and if it is, it sends out a DBus signal "timeZoneChange". I changed it from "configChanged" as I think "timeZoneChanged" makes way more sense.
