Why gravity slows down the time instead of speeding it up?

In Interstellar when they were on the water planet, every minute they spent there, several days passed on Earth. From outside observer’s point of view from Earth, everything happening on the water planet was in slow motion. Why isn’t it the other way around?

Time is relative. It takes 24 hours for the Earth to rotate and 365 days for it to revolve around the Sun. If you’re on a planet that’s on a larger orbit, then it would take more than 365 days for it to revolve. The Sun’s gravitational pull on planets further away from it will be weaker so the planets will move in their orbit slower.

Time is slower there because your basis of time is from Earth’s POV.
