I do keep the committer date when I intentionally modify some single special commit, but when I just keep changing stuff I don't do it. In my opinion this date is only useful if the committer and author are also different, for example when you pull some random change suggested in some forum you can put author and date from the forum in and yourself and the time of commit in the committer.

> Wouldn't you want to keep whatever the committer date already was?

Note, that when you create a new commit, the beginning committer and author date are always equal. So the original one is always the author date.

I find this flag useful, because it means that I can keep rebaseing and still reproduce the same commit hashes. This is really useful for asserting that nothing changed when the commit hash is equal or that really something changed when it is different. Otherwise the commit hash changes for all commits you touched in the rebase and you constantly need to verify if there was a change or not.
