> I am not sure we should do this: we are changing all functions' signatures because of a single function's requirement. > > I think we should add a node specifically for `NOW` and leave all the other functions' alone. We'll probably hit up against similar issues for current_date, current_time, current_timestamp, etc, in case that helps formulate what said node would look like. Interestingly, this is an instance where it would be much _easier_ if slightly less performant to implement as a UDF for certain use cases, because you could just close over some external state when building your execution ctx. -- This is an automated message from the Apache Git Service.
