[Developers] query for topic data at a specific timestamp

[Jack Alves]

Does anyone have an example query that returns only data present at a
specific time? I'm working with someone who wants to act as a trusted
authority for a set of topics. I heard about the technique of storing the
timestamp of a known good version. I don't know how to form that query.
