More and more SQL engines start supporting streaming functions, like

TUMBLE(rowtime, INTERVAL '1' HOUR)

described here https://calcite.apache.org/docs/stream.html#tumbling-windows-improved

Is it possible to support parameter list like "rowtime, INTERVAL '1' HOUR"?

Other functions like:
DATE_ADD(input_value, INTERVAL quantity_expr unit_of_time)
DATE_SUB(input_value, INTERVAL quantity_expr unit_of_time)
