What have you tried in the DateTimeConverter?
The DateTimeConverter is used to change the format, not to change the timezone. Also, you know the original data is UTC, but for the machine to know that it needs +00:00 added.
If you want to go from 20230821160000 UTC to local time, you can use @TimeZoneSet() in the AttributeCreator. See the documentation.
I think you need
@TimeZoneSet(@TimeZoneSet(20230821160000,utc),local)
which takes you datetime, set it to utc (adds +00:00) and converts that to your local timezone.
