Abstract
Time ordering may be defined by first defining the limit of no time ordering (NTO) in terms of a time average of an external interaction, V(t). Previously, time correlation was defined in terms of a similar limit called the independent time approximation (ITA). Experimental evidence for time correlation has not yet been distinguished from experimental evidence for time ordering.
