About

The printout shows the monotonic clock at 2:22 a.m. and the baseband and display clocks three minutes earlier. Yannetti suggested the discrepancy could explain differences between Apple Health and Waze data; Guarino testified that the artifact was a Powerlog showing Waze drawing power, not GPS data, and rejected that explanation.
