If time can go faster, and light can go faster.
How old was the light that left 1987a ? Trick question, the same as the distance in light years since no matter how fast or slow time flows an observer on a light beam experiences the same amount of time which is equivalent to the distance.
This may produce a discrepancy in our time. If you knew based on our time when the beam of light left 1987a and when it was detected here on Earth, I have some confidence that it would be significantly less than the measured distance to 1987a. If the beam of light passed through regions of faster Time Space on its way here, it would arrive early based on our clocks.
Stellar Cartographers are putting a price on my head as we type.
