IIUC, Glenn isn't interested in the "many repositories" sharing the common history. He's interested in the "official" repository (actually, his local mirror of that, but that's a distinction that makes no difference to his use case). From that point of view, it makes perfect sense to talk about when a commit was pushed to a particular repository. > So when was that commit pushed into the upstream repository?

I don't know what Glenn is looking for, aside from the push dates of each of a set of objects to some repo on Savannah. I suspect that creation date of certain files would indeed give a sufficiently accurate estimate, but of course with packs the blobs don't remain in the file system and so don't retain a blob creation date in git. I believe (and tried to explain briefly) that you are correct, that knowing such push dates won't help him much in understanding "what happened" in a particular merge. However, there is some use case that evidently is quite obvious to him that we may be missing; I don't think it's useful to speculate about what it is until he tells us more about it.
