Other than the author, a commit preserves even the committer, and the committing date; what's the difference compared to author and author date? First of all, don't worry too much about this: 99% of commits in your repository will have the same values for the author and committer, and the same dates.

In some situations, such as the cherry-pick, you carry an existing commit on top of another branch, making a brand-new commit that applies the same changes of the previous. In this case, the author and author date will remain the same, while the committer and the committing date will be related to the person who performed this operation and the date they did it. Later we will get in touch with this useful Git command.
