probably the most straightforward way is to use a MapperExtension with before_update() overridden to place the current timestamp in the "change" field of the instance, either by using a Python datetime function or by calling func.current.timestamp(). then that value will get sent in on the update. it wont inline the CURRENT_TIMESTAMP() call into the UPDATE but it will have the same end effect.
