Answer by Louis Maddox for Git clone changes file modification time

To do this in Python is simpler than some of these other options, as os.utime accepts the Unix timestamp output by the git log command. This example uses GitPython but it'd also work with subprocess.run to call git log.

import gitfrom os import utimefrom pathlib import Pathrepo_path = "my_repo"repo = git.Repo(repo_path)for n in repo.tree().list_traverse():    filepath = Path(repo.working_dir) / n.path    unixtime = repo.git.log("-1", "--format='%at'", "--", n.path    ).strip("'")    if not unixtime.isnumeric():        raise ValueError(            f"git log gave non-numeric timestamp {unixtime} for {n.path}"        )    utime(filepath, times=(int(unixtime), int(unixtime)))

This matches the results of the git restore-mtime command in this answer and the script in the highest rated answer.

If you're doing this immediately after cloning, then you can reuse the to_path parameter passed to git.Repo.clone_from instead of accessing the working_dir attribute on the Repo object.
