 Nozick argues that the timelessness of truth is a contentful empirical claim that might turn out to be false.A deflationary tack towards putative philosophical necessities such as this timelessness of truth, attempting to convert them into empirical issues, is a salient feature of the book.He takes the topic of truth to be the topic of what "determinately holds" ("A timeless truth that floats free of determinateness is a nonscience fiction") and appeals to quantum mechanics to show that there are problems about timeless truth as understood through determinateness.
