Actually not really, in earth there's different heights you can be at, low and high, a minute for one person can be slower for the other person, due us getting away from the earth's mass. The closer you are to it's mass the faster time moves, due to getting closer to a massive object's center of mass you closer get to the point where time is being effected the most. Due to when something has a big gravity (big mass) then time-space gets bent, so the furthur from earth's center of mass the further gravity effects you, causing time to be faster than the ones below.
