I understand above that it is easier understandable when reading
[2023-01-22 Sun 08:29@+1100] as it is assumed by poster (I guess Max)
that user will understand that there is +11 hours ahead.

That is assumption by poster. I do not find it easier.

As when user sees 08:29 that user will think of time in Berlin, of
time which is not in UTC, and not time in UTC plus 11 hours.

What is easier is what is generally accepted in any type of software
worldwide, just represent it in local time zone.

Difference between offset time and time with time zone is that time
zone includes rules of daylight savings and other anomalies.
