~850 years of ship time at max acceleration and the universe is 10^30 years old.
At this point, only white dwarfs, neutron stars, and various stellar remnants remain. Galaxies have dissipated, and stars like our Sun are a distant memory. (If any still exist to remember them. Which is, I'll add, not out of the question. Life can cling to structures built around black holes, white dwarfs, etc., and extract energy from those bodies for a very long time.) We're a long, long way from "heat death" -- from the Universe becoming an undifferentiated entropic sea of particles -- but it is already a very different place.
