If you enable the datamember of the OPCClient object for logging to database, then the timestamps will be stored. You can then use a sqlexec object to retrieve the data and timestamp you desire.

Enabling a datamember for looging, it will log that data with the system timestamp, not with the true timestamp (date of the aquisition). If i view data in a hyper trend i see data versus system date. All I am interested is if I can recreate a citadel with old data and timestamps in Lookout.
As I understand OPCLabview is OPC2.0 compliant. Is there a way in Lookout to access opc item properties, such as timestamp? (In Lookout I connect to OPCLabview, vi-based server)
Lookout is a OPC 2.0-compliant server and OPC 1.0-compliant client (link). You will not be able to access that time stamp in Lookout. Our LabVIEW DSC SW, on the other hand, is 2.0-compliant both as a server and a client.
