Research direction

Start by reviewing the implementations of timed_window, delay, and rate_limit, focusing on their use of time(). Determine how an event timestamp such as event['timestamp'] could be supplied for offline historical processing, and define the expected behavior before implementation. Done should include a clear supported approach for synthetic or event time.

Description

I want to use streamz for offline processing on historical data, the data is timestamped. Looking through source code, time related streams (e.g. timed_window, delay, rate_limit, etc.) use time() function for event time. Is it possible to fetch existing value (i.e. event['timestamp']) to these streams so I can do offline processing? If not, what would be the best way to go about this?
