during interactive rebasing, i sometimes find it necessary to move a
hunk from one commit to a later one in the branch. now, if that hunk
cannot be re-ordered with the later commit due to conflicting with it,
it becomes necessary to squash the later commit onto a temporary commit
created from the extracted hunk, not the other way around (or using a
stash). unfortunately, this causes the author date of the later commit
to be reset, which can rather seriously falsify the date if the branch
is long-lived.

You want `fixup -C` in the todo-list. See the hints near the end of the
todo-list.

Unfortunately "fixup -C" only copies the commit message not the 
authorship (that's usually a good thing but not it means it wont work 
for what Oswald wants to do). Maybe we should add another flag for 
fixup/squash commands to take the authorship from that commit. In the 
meantime creating the temporary commit with "git commit -C" is probably 
the easiest way to keep the original authorship.
