Yes, and "corrected commit dates" is about accommodating commits
with absurd out-of-sync timestamp mixed in a history with commits
with correct timestamp, right?  What happens if the absurd timestamp
is near the limit of the range?  You do not have to live through the
end of the universe---you only have to create a commit object that
records such a timestamp, no?
