We present a new Ginzburg-Landau theory for superconductivity in UPt{sub 3}, based upon a multicomponent order parameter transforming under an irreducible space group representation; the phase is staggered in real space. Our model can explain the {ital H}-{ital T}-{ital P} phase diagram including the tetracritical point for all field directions. We motivate this unconventional superconducting state in terms of odd-in-frequency pairing that may arise in one- or two-channel Kondo models, and suggest experimental tests.
