I'm pretty sure the theory of time dilation has been proven. They've put atomic clocks on jets and flown as fast as they can go for extended periods of time. When compared to an atomic clock on the ground, there is a time difference.

Also, Astronauts and Cosmonauts who have spent extended periods of time in space traveling 17,000MPH in orbit for thousands of hours will experience this:

"For every second you age on Earth, the cosmonaut in orbit ages 3 nanoseconds less. This doesn't seem like much, but it adds up; after a year the cosmonaut's watch will be 3.8 seconds behind your earthbound timepiece."
