I'm converting everything over to Git for my own personal use and I found some old versions of a file already in the repository. How do I commit it to the history in the correct order according the file's "date modified" so I have an accurate history of the file?

I was told something like this would work:

git filter-branch --env-filter="GIT_AUTHOR_DATE=... --index-filter "git commit path/to/file --date " --tag-name-filter cat -- --all  

This is what worked for me:

git commit --date="10 day ago" -m "Your commit message"
