Show that if a linear dynamical equation is controllable at $t_0$, then it is controllable at any $t<t_0$.

Consider a $n$-dimentional $p$-input equation:
$$dot{x}=Ax+Bu$$
where $A$ and $B$ are constant $ntimes n$ and $ntimes p$ real matrices.
By definition, the latter state equation is said to be controllable if for any initial state $x(0)=x_0$ and any final state $x_1$, there exists an input that transfers $x_0$ to $x_1$ in a finite time.
Then, how can I show that if a linear dynamical equation is controllable at $t_0$ then it is controllable at any $t<t_0$?.
I hope that you can help me.

Do you mean a linear time invariant system, because general linear systems also include linear time variant systems?

yeah linear time invariant system

Without loss of gbenerality, you can show if the terminal state $x_1=0$ at time $t_0$, then $x(t)=0$ for all $t>t_0$ .
