Set sequencer section time in 4.11?

Hi! My name is Alexander Shatalov and i am currently working on Allright Rig Plugin for Unreal Engine.
I have stacked with one tiny problem.
I can’t set start/end time for UMovieScene3DTransformSection in sequncer in Unreal Engine 4.11.
I have made it very easy in 4.10 and 4.12 by using SetEndTime command:

UMovieScene3DTransformSection *TransformSection;
TransformSection->SetEndTime(Time);

But it doesn’t work in Unreal Engine 4.11! I would very appreciate your help and time!
Thank you!
