How is it possible for the timestamp of the datalogger to be in local time and not in UTC? Local time UTC+2 is set to AXC F 2152 and the timestamp in datalogger *.db is UTC time.
As mentioned in the PLCnext Info Center, the DataLogger always stores timestamps in UTC. This cannot be changed.
It is assumed that the application that the customer uses to view the data can adjust the UTC time to the local time zone on the customer’s machine, if necessary. For example, UaExpert from Unified Automation does this when displaying historical data from the DataLogger on a PLCnext Control device.
