Timestamping Processor¶

The “Timestamping Processor” is installed with the Dataristix Application. The processor accepts any input values and forwards the values unmodified. It also adds a “Processing Timestamp” to the output that contains the UTC time when values were last forwarded. Insert the processor at one or more stages in the task pipeline to measure how long data takes to propagate between those stages, for example in combination with the Time Difference Processor.

Consider using the Value Properties Decoder to evaluate or process timestamps that were generated at the data source.

Add to Task¶

Add the “Timestamping Processor” to a task by dragging it from the “Build” panel onto the task’s “Task Builder” panel.

Example¶

The following example shows a task that receives inputs from an OPC UA datasource. The “SineSignals” dataset passes through the “Timestamping Processor” where a timestamp is applied and forwarded together with the dataset to the MQTT connector.
