It actually is! Minkowski 4D spacetime math models time as a geometric coordinate alongside 3D space. Because relativity of simultaneity shows that observers moving at different speeds disagree on what now is, past, present, and future cannot be absolute slices of time. They exist tenselessly in the block manifold. GPS atomic clocks are adjusted daily for these exact relativistic effects. Happy to hear how you interpret Minkowski geometry though!
