Abstract.  The non-absolutely convergent integral of some functions of dynamic equations

failed the requirement of the derivative of the function existing everywhere, and so the loss uniqueness of the indefinite integral is the setback in the theory of timescale calculus. In this work, we addressed this challenge in the context of the generalized ordinary differential equation. The well-established relationship between the dynamic equations on time-scale and the generalized ordinary differential equations is used to develop theorems and proofs on the

existence and uniqueness of solutions of the dynamic equations on time-scale. The notion is demonstrated with examples and the outcomes obtained validate the concept’s applicability.
