The point is that I'm not sure how something that doesn't actually change the system clock, such as moving from one time zone to another, would trigger this.

I'm guessing that they have some code that monitors the battery's performance over long intervals, keeping data on charge and discharge rates and how they slowly change over time as the battery ages, only somebody accidentally used local rather than UTC timestamps, and the resulting anomalies if the offsets change get magnified by long lever arms (so to speak) to create potentially large aberrations in the displayed results.
