> Users seem to get confused about how event time and watermarks work.
> We need to add documentation with two sections:
> 1. Event time and watermark progress in general
>   - Watermarks are generated at the sources
>   - How Watermarks progress through the streaming data flow
> 2. Ways that users can generate watermarks
>   - EventTimeSourceFunctions
>   - AscendingTimestampExtractor
>   - TimestampExtractor general case
