Change commit date

To set the current date we need only to do the following:

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

NOTE: the GIT_COMMITTER_DATE is for the committer while the --date is for the author.

it is possible to apply the author date to the committer date by using the --committer-date-is-author-date flag in the git rebase command. For example:

$ git rebase HEAD~x --committer-date-is-author-date

Here on example of how to do it manually and wrong.

GIT_COMMITTER_DATE="Tue Jun 7  4:44:34 PM -03 2022" git commit --amend --no-edit --date "Tue Jun 7  4:44:34 PM -03 2022"
