Could you clarify what you mean by this?

> The Frame "MLTime FrameTimestamps" of each sensor/camera seems to be independent from eachother. They starting point are not the same and the frequency is also different.  
> How could we get common timestamps which would mean the same time on the sam bases/epoch for all sensor/camera we use?

For synchronizing cameras, we recommend checking out [this solution](https://forum.magicleap.cloud/t/synchronous-capture-or-world-and-rgb-cameras-on-ml2/2149/5).
