We evaluate the time delay in some of the established resonance regions of πN elastic scattering. In addition to the positive peaks corresponding to resonances, we identify broad regions of negative time delay or time advancement. We compare the resonance parameters determined with the time delay method with those from conventional methods and try to interpret our observation of time advancement.
