We made an analysis of time-ordered diagrams for the two-nucleon T-matrix in chiral perturbation theory. From the analysis, it follows that low-energy nucleon dynamics is governed by the generalized dynamical equation [derived in J. Phys. A 32 (1999) 5657] with a nonlocal-in-time interaction operator. We also present an operator that parametrizes the nucleon-nucleon interaction in the ¹S₀ channel at leading order of the Weinberg power counting.
