When calling the Create Stream Marker API ([Reference | Twitch Developers](https://dev.twitch.tv/docs/api/reference/#create-stream-marker)), the documentation says that the `created_at` value should be “The UTC date and time (in RFC3339 format) of when the user created the marker.”.  
However the time returned includes nanoseconds, which isn’t valid RFC3339.

Here is a sample response from creating a stream marker  
`{"id": "6cc96f22d0c6f405414fe63d241aa156", "created_at": "2025-03-01T10:10:45.865184169Z", "position_seconds": 89, "description": "test"}`
