System time and valid time are independent time dimensions that are used for different purposes. Bitemporal tables include both dimensions. Changes to bitemporal tables that happen automatically as a result of row modifications are independent for the system-time and valid-time dimensions. These dimensions must be considered separately when determining what will happen to a row in a bitemporal table as a result of a row modification.
