Brann, Eva, "Time in the Timaeus," The Music of the Republic: Essays on Socrates' Conversations and Plato's Writings, Philadelphia: Paul Dry Books, 2004, 273-77.

Excerpt:

In the dialogue named after him, Timaeus has the divine Craftsman, who is making the heavens, say:

He thought of making a certain movable image of eternity, and, at once with ordering heaven, he made an eternal image going according to number, that which we have named Time (37 d 6 ff.).

This is, I believe, the second most often quoted sentence in the literature on time—just second to Augustine’s “What, then, is time? If nobody asks me I know; if I want to explain it to him who asks, I don’t know” (Confessions XI, 14).
