> 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.
