I have a set of commits where I'd like to find out when they were actually pushed upstream. It's a github enterprise server which I own, and someone committed a bunch of code, do to the nature of git I have to trust their timestamps. I would instead like to see when the code was actually pushed upstream, or when pushes upstream ever happened.
In particular if I could see when all commits were pushed at what point it'd be awesome. I've googled around and closes I can see is finding data using commit dates not push dates.
