The research tested 1700 devices. A single device that is off by 42 years (reset to Unix epoch?) would have skewed the average by over 9 days. So unless a number of other devices had similarly extreme errors in the opposite direction (and even if they did, I'm pretty sure the researcher would have only looked at the absolute magnitude of the error, not their direction), I think it would be safe to assume that extreme cases were excluded from the average.
Bnd you're right, 80% of them were within 30 minutes of the right time.
> "One in five were off by more than 30 minutes"
In fact, given that the article mentions daylight saving time as a major problem, I'm not surprised that the average error approaches half an hour. At any given time, a lot of machines would be running in the wrong timezone.
