Arrival time is when the parking brake is set by the flt crew (prior to jetway being connected, just after aircraft stops moving and is chocked by the ramper).</font>
You are describing how ACARS determines block in/out times. The actual definition of block out/in times (departure/arrival times) is based on when the aircraft first moves before a flight/stops following a flight.
The difference between the two should be no more than a couple of seconds unless the crew is intentionally trying to change the block time.
