Hi All,
I am working on a system with DeltaV v12.3.1. On the Operator Station that I am using, there is a strange recurrent issue with timestamps in Process History View that occurs every day between midnight and 8am. I believe the issue is specific to my Operator Station. Other stations do not have this issue, and the same issue applied regardless of whether I select one Events Data Server or the other. It also occurs regardless of the source node of the event.
It is easiest to describe the issue with specific dates. For example, at midnight on 7th October, the timestamp shifts from 10/07/2022 11:59pm to 11/07/2022 12:00am, then at 8am on 8th October the timestamp shifts back from 11/07/2022 7:59am to 10/08/2022 8:00am. That is, at midnight the month jumps forward by 1 instead of the day, then at 8am it corrects itself.
Any ideas as to what is going on here?

Link above. I'm not suggesting that this is the answer, just that it describes strange effects in dates due to regional settings.
