Standard gravitational lensing models anchored within the mainstream cosmology framework routinely rely on the introduction of hypothetical, unobservable Dark Matter halos to reconcile calculated time-delays with empirical telescope observations. This paper presents a formal alternative utilizing the Elbertse Time Field Model (ETFM), which eliminates the necessity for hidden mass parameters by introducing a localized, material-driven cosmic time field. By mapping the actual granular distribution of visible baryonic mass concentration behind galaxy cluster MACS J0417, we establish that light rays traversing the cluster perimeters experience substantially lower metrical resistance than predicted by smooth dark matter models. Consequently, we provide a completely blind, forward-looking calendar prediction for the re-emergence of Supernova Athena: September 27, 2027. This stands in sharp contrast to the mainstream consensus timeline of mid-to-late November 2027, offering an unalterable empirical test for cosmic time field mechanics.
