My favourite argumentation 😉

 

I am not sure about the archiver providing its own timestamps. This could lead to situations that misconfigured timing on the IOC side goes unnoticed ....


I am exclusively talking about archiving non-NT data that does not contain timestamps.
Heinz' case.
It might not be smart to have no timestamp, but refusing to archive without a clear message - sorry.
Our tools should be robust and help the users - not educate them.

Then the alarm status. The archived data comes practically always from IOCs(*)....


Again, I am exclusively talking about archiving non-NT data that does not contain alarm status.
Heinz' case.

I cannot imagine cases where this would not be interesting. 

Me neither, but our imagination is limited and not relevant.

EPICS has never kept the users from doing stupid things. I like that approach.
