Maybe we need a TRUNCATE_TIME_ZONE function, which for a

We could borrow general-purpose TRUNC() from Oracle but personally I
would prefer standard CAST().
Firebird already has a TRUNC. We already decided that CAST wasn't the
route to go, what are your arguments to reverse that decision?
The current behaviour of CAST to me makes more sense than the behaviour
defined in the standard. I can see that there might be cases when you
might want the time without time zone information as in the original
zone, but I think those cases are rare.
