Thanks for the inputs. Yes, the plan to to handle event based ts roughly along
those lines using the concept of "watermarks" and I am working on the same.

> Right now the time based windows uses the timestamp when the tuple is
> received by the bolt.
> However there are use cases where the tuples can be processed based on the
> time when they are actually generated vs the time when they are received. So
> we need to add support for processing events with a time lag and also have
> some way to specify and read tuple timestamps.
