The minor quibble that I have with John Sanders (besides the relations between divine persons idea) is that "duration of consciousness" (i.e., awareness) may be a necessary but it's probably not a sufficient condition for defining what time possibly means in relation to God. It's possible that a subjective view of time doesn't do justice to time itself, much less God's relationship to time.
Thinking (intentional cogitating) is one form of awareness, but there are also forms of consciousness that do not involve thinking per se. The quibble is a small one since I agree with Sanders that time is uncreated. From what I understand, at least, he doesn't believe that time is a created thing.
