This work presents Part II of the Myominaung Unified Theory (MUT), focusing on a phenomenological reinterpretation of cosmic time and its implications for early galaxy formation. Instead of treating cosmic time as a strictly uniform background parameter, the framework models cosmic age as an accumulated quantity regulated by large-scale field evolution.The model introduces a transient, scale-dependent modification to the effective expansion rate at high redshift, interpreted as an early-time “metric stiffness.” This results in a modest extension of the effective cosmic time available at redshifts �, of order a few hundred million years, while preserving late-time cosmology, the present-day Hubble constant, and gravitational-wave propagation.The proposed framework offers a conservative and testable approach to alleviating recent tensions between standard �CDM structure-formation timelines and the unexpectedly rapid assembly of massive galaxies observed by the James Webb Space Telescope (JWST), without invoking exotic astrophysical processes or modifications of gravity. This work is intended as a phenomenological extension rather than a complete theory of cosmic time.
