Recursively change the timestamps on all commits of a GIT repo

I want to write a simple script that would go over a git repo and change the timestamp of each commit accordingly. Yet, I have no idea where to begin from. Any advice for a first step?

Use git filter-branch. It has a number of filters you can apply which can alter commits. Be warned that it's destructive and will rewrite the history of your project.

The git filter-branch (docs) command is designed to do tasks exactly like this. The trick is figuring out what you want to change the timestamps to.

You can pass a filter to git filter-branch using --commit-filter, then modify the GIT_AUTHOR_DATE and GIT_COMMITTER_DATE environment variables. Here is an example, which sets the commit date of all commits to January 1, 1970:

git filter-branch --commit-filter 'GIT_COMMITTER_DATE=1970-01-01T12:34:56'
