Keep the original commit date in jj rebase

[clavia-lang]

Hi. Thanks for the awesome work on Jujutsu! I know that destroying revision history is a bad idea.

I am organizing my revision history with terrible workflows from the root commit, but jj rebase always changes the commit date. I tried git rebase, but it's hard to use.

How about adding an argument to prevent jj rebase from overriding the original commit date (and author date)? Thanks!

Is this something you want to use on an ongoing basis, or are you doing a one-time cleanup of your repository?

If you're doing a one-time cleanup, maybe it would be easier to use git-filter-repo instead?

Thanks for your quickly reply. I am doing a one-time cleanup. I have hundreds of revisions that branch and merge haphazardly (such as forgot to use --rebase when using git pull), but I still want to keep the revision history.
