How to setup 12 FPS in sequencer

Hi All,
I have Imported alembic cache from maya , animated with 12 fps. I am trying to setup the same in sequencer, But Sequencer dose not have any option to change the scene to 12 FPS. Is there any way where i can render or setup my scene to 12 FPS.

Thanks
Rohan M

You need set 0,0833333333333333, is the result of 1 Seconds divide by 12 frames
