Time-base limitations on user-manage profile

If I have a pppoe server using radius to authenticate, and I create a profile and add 2 limitations to it, one limitation of 1mbps and another of 2mbps, and set the 1mbps limitation to work from 00:00 till 12:00 and the 2mbps limitation to work from 12:01 to 23:59:59, does ROS will chance it’s queue automatic as time passes, or it will only be checked on the moment of authentication and never be checked again?
