Subject: A couple of questoins re QuickOPC

Gentlemen,

[...] I have been able to make very good progress using QuickOPC and have the following questions:

1) The time returned in the Timestamps is always “later” by 4 hours versus my local machine time. Why? Does this have anything to do with time zone or some other setting?
2) How do I get the timestamp of the last value change based on the time stored in KepServerEX? The timestamp returned seems to be the time the tag was last updated / read by my application and not the time the value actually changed as recorded by KepServerEX? As a result, this value changes every time I restart the application which is a problem.


Regards,
M.
