Excerpt

CesiumJS Time, Properties & Animation

Version baseline: CesiumJS v1.143

Covers the temporal data-binding layer: Clock/JulianDate time system, the Property hierarchy that makes entity attributes change over time, interpolation algorithms, splines, and material properties. Properties live here (not with Entities) because SampledProperty and CallbackProperty are meaningless without Clock/JulianDate. The Material class (Fabric) belongs in cesiumjs-materials-shaders.

JulianDate -- The Time Primitive

Stores whole days + fractional seconds separately for precision. Always uses TAI internally.
