We formulate a geometric framework for temporality within a six–dimensional symplectic setting in which time is not introduced as a primitive background parameter, but appears through a hierarchy of structural readouts. Four temporal regimes are identified: Hamiltonian flow time, internal phase time, effective Lorentzian time, and entropy–ordered cosmological temporality. These are interpreted as related projections of a common underlying symplectic carrier. On this basis, we introduce the notion of temporal unification: locally defined phase clocks become globally comparable under admissible convergence and phase locking, thereby yielding an effective observable time coordinate. We further argue that residual relative phases surviving incomplete temporal unification induce a metric structure, providing a geometric interpretation of emergent space as residual phase geometry. The paper is intended as a foundational synthesis. It organises the chain tension structure → Hamiltonian / translation structure → energy readout → time as flow parameter, and isolates the principal conjectural bridges linking convergence, coherence, observable temporality, and emergent spatial dimension.
