It looks like Siemens is displaying the time in UTC and Ignition displaying the time adjusted for your time zone.

The PLC time is correct, the Ignition time is not.

Else I’m ahead of time by 1 hour.

You've made a mistake treating the time you see in an LDT value (in TIA Portal) as your local time, when it is in fact UTC time.
