Which column in the view v_SnapshotData contains the timestamp of when an event occurred?

The correct choice is the column that specifically captures the time at which an event happened. In the context of a view like v_SnapshotData within AVEVA Historian, the naming convention for columns is typically designed to provide clarity regarding their purpose.

The column labeled EventTime is intended to store the exact time an event occurred, making it crucial for time-series data analysis and reporting. This timestamp allows users to track when specific activities or changes took place, which is essential for monitoring and analyzing historical data effectively.

The other columns serve different purposes: EventDate may refer to the date component of an event without the specific time, EventID likely serves as a unique identifier for events, and EventStatus might describe the condition or status of the event at the time of logging. However, to ascertain the precise moment of an occurrence, EventTime is the most accurate choice.
