 You should only use

s/lie/override/ ?

It cannot be "fixing an earlier mistake by overriding the correct
data".  It is deliberately using a data that does not match the
reality to replace what was recorded, so in this case, "lie" would
be the proper characterization, I would think.

Okay. I don’t think he was saying “fix” but just the more neutral
“override”.

I was more confused last year[1] about the use-case here, in turn more
dismissive; I thought that it was just a vanity thing. I’m all for
dictating what the author date is since that’s my judgement to make, and
moreover such fiddling is naturally tempered by common sense. (Did I
author this between one month ago and now: yes, because I originally
wrote it one month ago and then amended it three times in this
timestamp. Did I author this *three months* ago: No, I hadn’t even
thought about it at that point. That’s just a lie).

It’s easy to have a common sense for the authoring date because everyone
knows of “authoring”. It’s more difficult for people to have common
sense for the commit date if they don’t know what “committer” is for.

I guess I like the pointed “lie” in this case because uncareful lying
can cause technical issues. So you better sharpen your senses and have a
real reason for doing it.
