Resumen:
We introduce a new notion of good sections at null infinity which
permits one to define a desired canonical retarded time in isolated
systems. This construction depends on the properties of the physical
system at the fixed retarded time, in contrast to previous works where
conditions at − ∞ (or + ∞) retarded time gave a global choice of
preferred sections.
