The PR looks GREAT! Thanks, very good job.

My only question is: I see you included a new repo in test-repos.zip, and the size went up 180% (+25Mb). So I imagine you included a large repo. Would it be possible to create a small repo? I think (BIG assumption here) you can play with the date of your PC (like make a commit, change the date of your PC to another timezone, make another commit, change it back, etc...).

If it's not possible no worries, I will land it as is and will try to come up with something else 👍

Somehow test-repos/ got inflated. So I downloaded the zip file from the GitHub, added the since_as_filter/ repository again and zipped everything.

Now it should be fine (file size: 31Mb).

Thanks for catching this.
