PPPoE session termination time on Radius

Is there anyone can set PPPoE session termination time on Radius and it works? As I know WISPr-Session-Terminate-Time is works only for Hotspot, not for PPPoE sessions.

Session-Timeout attribute

I guess Session-Timeout indicates how long user can be logged-in without interruption. Session-Timeout includes duration of time, but not date and also it counts from the start every time when user login.

That`s not solution.
