Story summary

A study finds time moves faster on Mars than Earth, with clocks about 477 microseconds per day ahead.
Researchers Neil Ashby and Bijunath Patla of the National Institute of Standards and Technology analyzed Mars’ gravity and orbital shape, finding they affect time differently from Earth.
The study notes daily clock-speed changes up to 226 microseconds.
However, about 100 nanoseconds per day may require resets every 100 days.
