I left that part out. I can't decide if it is a bug or a feature that
the reflog retains the same timestamp.
I.e., I'm not sure it would be wrong to do:
diff --git a/refs/files-backend.c b/refs/files-backend.c
index 12290d2..465cfc5 100644
--- a/refs/files-backend.c
+++ b/refs/files-backend.c

result = log_ref_write_fd(logfd, old_sha1, new_sha1,
git_committer_info(0), msg);

on top. If somebody writes a lot of refs without updating any commit
objects, should those all have a stable timestamp or not?
On the one hand, moving the timestamp reflects reality.
On the other, I have done dirty things in the past like "undoing" the
results of somebody's mistaken:
git clone ...
git push --mirror ;# oops, this deletes everything except master!
by grouping ref updates according to their reflog mtimes.
So I kind of punted by not changing it but also not making any claims
either way. :)
