How to add time label

Hi all,

How do I add a time label to my entity in sandcastle?
For eg,in the Interpolation demo

There is a plane that move along the path towards different point.
Is there anyway I can add a time label at each point, showing its actual update instead?

Live streaming of data > Read Data(Entity) > Add a point to the entity (point include its id name, actual time at that point > Every 10s, it will render and if there are updates, new point will be created etc.
