It basically means that time is irrelevant. If you lived homeless, with no job, or responsibilities, it's easier to understand. In a homeless person's case, does time really matter to them? Clocks only exist.
A clock exists because it is in the here & now & you can see it. Time is unseen. A person or any animal does not know of time without external references of the past, here & now etc. So therefore without some reference point, time is meaningless.
