Add testGetSeconds to verify that getSeconds represents whole seconds in the local time zone. For a given instance of DateAndTime, changing the time zone offset changes the local representation, but does not affect magnitude (time since a defiined epoch). Therefore, if time zone offset changes, the asSeconds value should not change, and the getSeconds value should change to reflect local timezone.
