It doesn't mean that time exists as a phenomenon in itself.
Time exists in itself, but not really the limited way we can experience it. Time is more of a measurement between two points referenced to other measured aspects for a given set of known and measured conditions.
Time "travels" at different speeds in a measurable way even at different heights within the same room, and can be accurately calculated before being measured. Time doesn't really move in one "direction," either. We can only sense it one way as referenced to conditions right here and processed by a set of somewhat questionable organic electric impulses.
Polarized and encoded photons can now be measured "traveling backwards" through time, leading to a very real possibility of breaking through Heisenberg's Uncertainty Principle. Although these results are very recent (and need to be independently tested thoroughly), it could possibly once and for all determine whether anti-particles are actually "traveling backwards" through time or just appear to.
