gh-122272: guarantee specifiers %F and %C for datetime.strftime to be 0-padded by blhsing · Pull Request #122436 · python/cpython

My last push produced an error in a thread sanitizer check from code completely unrelated to mine , so I thought I'd try "fixing" the error by rebasing my branch to the latest master in hope that someone else already fixed the issue, and that resulted in the massive inclusion of all commits between the master my branch was originally based on and the latest master.

I tried to undo my rebase by force-pushing my last commit to the branch, but it still results in the code owners of all unrelated commits being tagged as reviewers for this PR by GitHub. Sorry about that.
