The timestamps don't tell the whole story (Fairino FR5)

I'm reconstructing a failed part acceptance recording attempt on Fairino FR5 in a commissioning station recording job events, using a sample housing. Our Python log, PLC trace and controller event list have disagreeing timestamps. The application also reused its job label after a restart. I can see a timeout, but I can't tell which attempt an acknowledgement belongs to.

Got a process-start entry? That could separate the reused labels without trusting another machine's clock.

@LiamArcher0403 I've found the process-start line, so our Python entries can be divided into two sessions. I still can't link the PLC acknowledgement to a specific attempt.
