Data with a time stamp that exceeds the RealTimeWindow parameter is known as?

Data with a time stamp that exceeds the RealTimeWindow parameter is classified as late data. This term specifically refers to data that has been received after the expected timeframe established by the RealTimeWindow, which is used to manage the timing of data acquisition and processing within a historian system. Late data can occur due to delays in data transmission or other factors that affect the timeliness of data capture.

Understanding that late data is still valid but has arrived outside of the intended real-time window is crucial. It can still be useful for historical analysis but may not be suitable for real-time monitoring where timely data is critical. The RealTimeWindow serves as a boundary for what is considered current or timely data, thus emphasizing the importance of proper time management in data handling.

In contrast, terms like old data and archived data could imply data that has been deliberately moved for long-term storage, while invalid data refers to data that cannot be processed due to errors or inconsistencies.
