June 12, 2020

  1. Start rebase process with

     git rebase -i HEAD~<number of commits to rebase>
  2. Editor is shown with all commits listed. Change all pick to edit for the ones you want to update. Save and exit editor

  3. Then for each commit rebase do the following:

    • Set environment variable for GIT_COMMITTER_DATE to the date you want to update to, i.e:

        $env:GIT_COMMITTER_DATE = "2020-05-05T14:00:00 -0600"
    • Next do a commit with the updated dates:

        git commit --amend --no-edit --date=$env:GIT_COMMITTER_DATE
    • Then continue to the next commit to rebase by typing:

        git rebase --continue

    Note - These examples are using PowerShell as the command line
