1. Summary of findings
The dashcam clock was set to Eastern time and ran 37 seconds fast. After correction, the light turned red at 3:31:16 PM Pacific.
The truck’s hard braking, recorded at 15:31:40.2, began 24.2 seconds after the light turned red.
The 911 call log places the report at 3:32 PM. The log records minutes only, so it cannot be placed more precisely.
The witness’s “around 3:30” is consistent with the corrected sequence but is a human estimate and was not corrected.

5. Limits of the record
What this record cannot tell you, stated plainly so it is not discovered on cross-examination.
No source captures the moment of impact. The collision falls between hard braking at 3:31:40.2 PM and the 911 call at 3:32 PM.
The 911 log is precise only to the minute and is not shown as more accurate than that.
The witness estimate is included for context and does not anchor any other event.
6. Method and audit trail
Events were extracted with AI assistance and each one was checked by an analyst against its source before entering the sequence.
Every correction is logged with who made it, when, and why, and can be reversed.
The same documented method is applied to every case, so your expert can explain how each time was reached.
