Julian Hyde commented on CALCITE-7139:
--------------------------------------
You are trying use a TIMESTAMP WITH TIMEZONE in an AS OF clause. That is, you
are using a feature that has not been implemented. First, let’s decide whether
that feature should be implemented. Then either implement it or give a better
error.
Can you please change the summary?
