Earth time and vary with time at space station

One year on Earth vary with time of the year at the International Space Station (ISS). Although the difference is not too significant.

One year in orbit (in the ISS) is equivalent to 0.9999999997 years on Earth.

In other words, when we experienced a year on Earth, astronauts in the ISS experienced only less than one full year on Earth.

In particular, the astronauts experienced shorter 0.0000000003 year, or about 0.01 seconds than we are on Earth.
