I was wondering if you could possibly make a form of time measurement that would apply to a planet in a galaxy and then another planet that is ~20,000 light years away. I want a unit of time that, for both planets, will be a whole number. Also here's useful info about the first planet (the planet I've been working on)...
1 year on the planet is 539 earth days.
Plants and trees are thriving.
There is a star that provides light about 150 million km away from the planet.
