[GIT]Is there anyway to find out when a commit was merged to a branch?

[raminaa niilian]

I am looking for a way to find-out when a particular commit has appeared in a branch. Let's say we have a commit, abc4587, in branch dev and the branch at some point was merged to prod branch. What I am looking to findout is when that merge has happened to bring the commit abc4587 to dev branch.

Thanks.

Doesn't "git log" give you that information? How is what you are asking for different from that?
