Description

Currently, users need to specify the notion of time (ProcessingTime/EventTime) for timers and ttl separately. This allows users to use a single parameter.

We do not expect users to use mix/match EventTime/ProcessingTime for timers and ttl in a single query because it makes hard to reason about the time semantics (when will timer be fired?, when will the state be evicted? etc.). Its simpler to stick to one notion of time throughout timers and ttl.
