An old bug had caused the redirect created from a move overwriting a pre-existing redirect to have the timestamp of the original overwritten redirect rather than the time the move occurred, as seen from Wikipedia:Moving a page#Moving over a redirect. This applies in particular to the February 2002 edit listed in Charles Matthews' contributions as well as the February and July 2002 edits listed in Patrick's contributions. We should fix the rev_timestamp for these revisions, perhaps by looking at the talk page move that shows the correct timestamp. If any such redirect had since been deleted, then we would instead need to fix ar_timestamp.
