No, that would be nasty, partly for the corner case you mention, but
partly because I just think it's wrong to try to lie about reality.
The reason I noticed this in the first place was actually that I just
wanted to take a look whether things had gotten slower or faster over
time, and see how many patches per second I get from the patch-bombs
Andrew sends me.
So getting real time was what I was looking for.
Also, before somebody asks: the reason git has always cached the
"default time" string is because there's a reverse annoying thing,
which is looking up time twice, and getting a difference of a second
between author times and committer times just because of bad luck.
That makes no sense either, and is actually why we have that
"ident_default_date()" cache thing going on.
So we do want to cache things for a single commit, it's just that for
things like "git am" (or, like Junio wondered, "git rebase" - I didn't
check) we probabyl just just flush the cache in between commits.
