Morphology

terrestrial + dynamical + time

A learner who knows 'terrestrial' (Earth-related) and 'time' can infer this refers to a kind of time tied to the Earth, and the component 'dynamical' signals a relation to Earth's motions or dynamics. However, the phrase is a technical astronomical term whose precise sense (a specific timescale corrected for orbital variations) requires domain knowledge and the specialized meaning of 'dynamical', so the full meaning is not fully predictable from the parts alone.

Etymology

Terrestrial dynamical time comes from its parts: terrestrial ('Earth'), dynamical ('motion and forces'), and time. Imagine a clock that keeps time by watching how the Earth moves and changes, so the name means a 'measure of time' based on Earth's motion and small changes in that motion.
