Create a Git Commit with a Specific Date

You want an existing commit to carry an exact timestamp — not “whatever the clock says now”. git-edit-date lets you set that date (and many others) in a spreadsheet — no git commit --amend.

What is git-edit-date?

A free Linux CLI for when you already have history and need exact dates applied in bulk. Export the branch to CSV, type the timestamps you want, apply once.

How to set a specific date

git-edit-date export -o commits.csv
# set author_date and committer_date to the exact timestamps you want
git-edit-date apply -file=commits.csv
git push --force-with-lease

When you need this

One or many commits need an exact RFC3339 timestamp
You want author and committer dates to match (cleaner git log --format=fuller)
Fixing a whole branch of wrong dates — review in CSV first
