Ahh, duplicate.

Feature request: createdAt and updatedAt fields on model

Ah, well we do track those values in the indexing database, but that will just be the timestamps when the local node learned about the stream/update, not necessarily when the create/update actually originally happened. The best way to tell when a stream was created or updated is to check the stream log for anchor commits and see when the anchors happened. It’s not perfectly precise, but will give you a general sense for when the various commits in the stream were created.
