Is the age of the universe relative, depending on how close you are to a black hole?

In the movie, Interstellar, the people who went to the first planet lived one hour for every seven years on earth due to a nearby black hole. So, in order to make things easy, let's assume the universe is exactly 14 billion years old if perceived from Earth, and the new planet is called Planet X.

Math involved: 

1 Planet X hour = 7 Earth years 

1 Planet X hour = 61,320 Earth hours


This leads me to believe that the the universe from Planet X is perceived 61,320 times more slowly? Or, maybe the black hole will swallow any light that comes near this planet anyways, so the night sky is entirely skewed, useless to making precise calculations?


So, if we were to go with time as being perceived 61,320 times more slowly on the surface of Planet X, the math for Earth's vs. Planet X's representation of the age of the universe would be:


14,000,000,000 years ÷ 61,320 = 228,310 year old universe standing on Planet X.


By no means am I a theoretical physicist, or terribly good at math. Additionally, everything that I thought about may be dead wrong. This just happened to pop into my head one day, and I have been thinking of the answer to it ever since.

If a black hole formed immediately after the universe began and you spent the time orbiting just outside the photon sphere, then it wouldn't take long to get to now. But that's not what "the age of the universe" means. The age of the universe is the time experienced if you're moving with the Cosmic Microwave Background and away from any gravitational fields.

In other words, you're right about the physics, but wrong about the semantics.
