FYI, the default agenda behaviour around a month ago was exactly what
you want to avoid (assuming that you use active timestamps). I explained
in more details in https://list.orgmode.org/87h77psaik.fsf@gmail.com/T/#me4f41a8b36ada384d87cf028ef10164dfa526ad2
Let's keep discussion of the original issue in the original thread.

I sympathise with you. I still remember my struggle when I had to travel
across multiple time zones. Anyway, the timezone issue have been
discussed multiple times within last 10 years or so. It is complex and
nobody managed to come with a good idea how to approach it.
