Function:

In a Workflow:

You would use this activity to obtain the current time extent of a time-aware layer. The Get Feature Layer Info activity can return cached information from when the service was started. The Get Feature Layer Info Updates activity forces ArcGIS Server to return the most current information rather than cached information. This is useful for time-aware layers that undergo updates and edits that could change the time extent of the service.

This activity requires ArcGIS Server v.10.1+.
