Introduction: A radio controlled weather station clock stays accurate by listening to a longwave time broadcast, not by carrying an atomic clock inside its case. Most people who buy a wireless weather station expect the clock to be right without any fuss, and that expectation hides a simple question: where does the time actually come from?

Keeping that split in mind — quartz runs the clock, radio corrects it — makes the wording on retail listings much easier to read, explains why a new unit sometimes needs a night or two before it settles, and separates a genuinely radio-controlled design from loose marketing talk about atomic accuracy.
