/I/ never told you anything about it :)

Commits are immutable. A fix would be to edit the offending commits to
create new commits with a more reasonable date. Then everything in the
future from those rewritten commits would be replayed to create a new
master branch that doesn't have the tainted history.

From git's point of view this new master branch would be a fork that has
branched off at the time of the date fix: in 2006.

"git filter-branch"

This is relatively straightforward. I can make a fixed master branch, if
you'd like to look at it.

You can go back and change whatever you like, but each time you do that,
you're making a new fork. In my view it could be justified to fix a
failure (like the one that started this thread), but not for anything
else. Even in this case, it's not obviously justified: you need an old
git and/or i686 AND the failure only shows up if you "git fsck"
