Documentation Request Summary:

Each entry in the change stream will now include a 'clusterTime' field, which is equivalent to the 'ts' field from the oplog entry that generated it.

Scope of changes:

• reference/change-events

• not sure if we need to blurb in the main changeStream page as we don't go into event details.

Impact to other docs outside of this product:

Engineering Ticket Description:

By exposing the "ts" field from the oplog entry in a changestream entry, we give the consumer all the information they need to create a BSON document that sorts in the same order as changestream entries appear, without needing to make the resume token transparent.
