Summary0001400: Use of timestamp in DataValue for bad status is inconsistent
Description

7.19.2 DataChangeNotification parameter
Table 148 -> value
If the StatusCode indicates an error then the value and timestamp(s) are to be
ignored.

7.7 DataValue
Definition SourceTimestamp / ServerTimestamp:
In the case of a bad or uncertain status, serverTimestamp is used to reflect the time that the Server received the status or that the Server last tried to recover from the bad or uncertain status.

It makes no sense to define a special behaviour for the DataChangeNotification and it makes sense to use at least the server timestamp

Changed DataValue description regarding timestamps in DataChangeNotification definition to be consistent with DataValue structure definition. The source timestamp is valid for bad or uncertain status.

Change is part of the draft version "OPC UA Part 4 - Services Draft 1.02.02 Body.doc"
