For instructional and training scenarios, it is often helpful to show the distribution of points collected by a GNSS receiver over time, while the receiver remains at a fixed location. Later on, you might have people convert a streamed line's vertices that captured the drift over time to points to explore statistically in ArcGIS Pro or Map Viewer. To support these kinds of activities, it would be helpful to have a true Time setting for Streaming under Collection Settings in ArcGIS Field Maps.
Currently, while you can set the Time setting to 1-second, it is overridden by an additional, hidden constraint when streaming, “The distance traveled from the previous vertex must be greater than the current GPS accuracy divided by two (from BUG-000142136, which has been closed).”

So currently, even if you set the Streaming Time interval, you do not necessarily get a vertex recorded for every interval. A new vertex is only recorded if the receiver has sufficient apparent drift during the interval to be greater than the previously mentioned criteria.
To support the describe use case, the Idea is to have a way to set a streaming time interval that would not be overridden by other factors.
Thanks for considering!
