"am" being a tool to accept patches written in some past to faithfully record both author timestamp and committer timestamp, what you seem to want is outside of the current scope of the tool.
A patch to butcher "git-am" to copy GIT_COMMITTER_DATE from GIT_AUTHOR_DATE and export it should be trivial to implement, though.
Perhaps something like this totally untested patch.
