What view returns data on when an event occurred?

The view that returns data on when an event occurred is the EventHistory. This view is specifically designed to store and retrieve historical information regarding events that have taken place within a system. It captures key timestamps associated with each event, which are essential for tracking the timing and sequence of occurrences over time.

In contrast, while the other views may provide data on events, they serve different purposes. For instance, EventStatus may provide real-time statuses of events, offering a snapshot of current conditions but not the historical timing information that EventHistory delivers. Similarly, EventLog typically records the events in a way that may not focus on time-specific details, and SnapshotData is generally used for capturing data at a specific point in time without the historical context of when events actually happened. Therefore, EventHistory is the most appropriate choice when seeking to understand when specific events occurred.
