How do I use Ash.Transform
I need to shift the time_zone of some (DateTime) attributes from a resource. Ideally, I’d like to do it right after records are loaded from db. Is it possible? How?

There is some frustratingly out of date bits here: Ash.Resource.Preparation — ash v3.29.3
Ultimately a preparation can look one of two ways:
prepare fn query, context ->
...
end
# or
prepare Module
prepare {Module, foo: :bar} # or with opts
defmodule Module do
use Ash.Resource.Preparation
def prepare(query, opts, context) do
query
end
end
The actions guide talks more about the lifefcycle of each action type. Actions — ash v3.29.3
