Let's forget about updating time in clock for a moment (let's focus on
tooltip). I could use

void Clock::updateToolTip() {
    Plasma::ToolTipData tipData;
    tipData.mainText = currentTime();
    setToolTip(tipData);
    dataEngine("time")->connectSource(m_timezone, this,
updateInterval(), intervalAlignment());
}

but still I don't have anything like removedToolTip() to use

void Clock::removedToolTip() {
    dataEngine("time")->disconnectSource(m_timezone, this);
}
