Yes, I'm looking at both times you mention really, the comparison between the scheduled arrival time as published, and the actual time announced, to determine the accuracy of the "on time arrival" statistics. By taking the actual arrival time as the touchdown time this seems to distort these figures of how many arrivals are on time, or within some tolerance (typically up to 15 minutes).
