Check the geometry and then compare it to a Ridley cx bike. 4Za is Ridley's house brand, they make more cross bike than time, and those decals are pretty amateurish. I would be very surprised, aside from it being an alloy frame, that anyone at Time (or Ridley) would let that design and quality of paint go out the door.
I had a Ridley Arena track bike and that tubing looks really familiar.
