I construct an effective field theory (EFT) for the minimal degrees of freedom of supersymmetric inflation. These can be viewed as the goldstone of spontaneously broken time translations, and the goldstino of spontaneously broken SUSY, both of which are tied together in an interesting way through the structure of the SUSY algebra. I briefly outline some phenomenological consequences, including a modified goldstino/gravitino dispersion relation and a time-dependent gravitino mass phase.
