Refresh commit date

Imagine that you made some commits for which you would like to update the time or a date.(so that you would keep only the chronological order)

Now if you were to do it on the latest commit, you can just run:

GIT_COMMITTER_DATE="$(date)" git commit --amend --no-edit --date "$(date)"

and that would update the date of the last commit, so you can then push or push force it.

Multiple commits

To perform this action in bulk mode you can just run:

git rebase HEAD~{number of commits} --ignore-date

You can also create a shortcut in your ~/.gitconfig like so:

[alias]
  refresh = "!f() { git rebase HEAD~$1 --ignore-date; }; f"

where the parameter would be number of commits starting from HEAD to update, i.e.:

git refresh 6
