Yes.

No.

This answer assumes that what you want to do is the following:

* Create a tag for the state of a ref (such as HEAD) on the central repo
at a specific date and time.

No client can know this. Reflogs are local. The point of your tagging (as I understand it) is to create an authoritative date based tag, and only the central repo has the necessary info.

If you want to do something different you should say so ;) But note that committer and author dates are completely bogus from the point of view of "was in the central repo at a certain date", they have nothing to do with that.
