Meaning

The line works on two levels at once. On the surface it is a playful philosophical claim, borrowed loosely from ideas about the nature of time, that time itself is not the solid, reliable thing we treat it as. Then it immediately undercuts any sense of cosmic profundity by singling out lunchtime as especially illusory, which is funny precisely because lunchtime is one of the most eagerly anticipated and concretely real moments in an ordinary person's day. The joke is the collision between grand metaphysics and the very human desire for a sandwich.

Context

This line appears in The Hitchhiker's Guide to the Galaxy, Douglas Adams's comic science fiction novel first published in 1979, which began as a BBC radio series before becoming a book. The story follows an ordinary Englishman swept into an absurd universe, and the narrative voice frequently pauses to deliver deadpan observations on existence, physics, bureaucracy, and other large topics. The remark about time is delivered in that characteristic mode: starting with a concept that sounds almost serious and ending somewhere unexpectedly mundane.
