The exact time it ends is not defined, but if you alter history it is assured. As an indirect result, you cannot return to your original time.
If the change just ends yourself immediately, then "the exact time it ends is not defined" would be incorrect, because you know it will end at the moment you do the change.
Instead I interpreted it as that at the moment you inform your previous self, the "you" that did the informing is cut loose from causality. The universe won't like that and will sooner or later end your existence, but how long "time" it takes until it catches up with you is undefined.
