git log --since to not stop after first old commit?

Hi,

I wanted to look at commits of a contributor from the last year, and noticed that I only see commits from this year, not last year when I use:

        git log --author="that person" --since="1 year ago"

Digging around in the history, one other contributor pushed a mistake on 1st Jan, where the author date was supposed to be 2022-01-01, but happened to be 2021-01-01. Knowing that, it makes sense that 'git log' stopped at that commit by default.

I wonder though, is there any option to "force" git log to walk all reachable commits from HEAD, but just show the ones which match the --since criteria?

Or is this need so special that the best is to parse the output of 'git rev-list' and do my own filtering for author and date?

Thanks,

Miklos
