I'm not 100% sure, but it looks like profile_created and user_created are actually holding the value of when the profile or user was updated, and profile_updated and user_updated are holding the value of when the profile or user was created.... try using the updated variables and see if you get the results your looking for.
If so, we may need to get this fixed as I don't think that is suppose to be like that.
