TBC automatically keeps a change log in memory to enable its undo operations. You can see it in the Change History view, but it is not persisted and is cleared once the file is closed.
TopBraid EVN, on the other hand, does exactly what you are asking for. Each change is persisted together with a time stamp and a user ID. Each model that is being developed using EVN has two graphs - graph containing the model itself and graph containing all the changes to the model plus a few additional pieces of metadata. You can try EVN in a standalone single user mode in TBC Maestro Edition (as per Mark's instructions) or you can request an evaluation account on our server (from a link on this page http://www.topquadrant.com/products/topbraid-enterprise-vocabulary-net/) to experience it in a collaborative mode with multiple users.
