How to set the (git)commit time to be the time of last jj desc instead of the initialization time(i.e. jj new)

[Ziqi-Yang]

I always have a new empty slot for new work. And I do this style to push git repo

# there is already a empty slot, the time shown in the git log is the time that this slot created
# edit file
jj desc
jj new
jj branch set main -r @-
jj git push

And the time displaying in git log is the time that the new slot created. I want to have time displayed as last jj desc.

See git help log for how to tell it to show the committer timestamp instead of the author timestamp.

I think you might also be asking if we could update the author date later. See #2000 for that.
