Mach 3 is only about 2200 miles per hour, it's really not that fast. It would actually take about 10 hours (assuming the earth was still, and
rounding a bit), to go around the world at that speed. If you're talking about the speed of light like syrinx mentioned, then that woudl be a
"As an object or person is accelerated toward the speed of light time slows down for it/him.
This last property leads to the "twins" effect: Twin brothers live on Earth. One brother takes a trip to a distant star traveling at a high
percentage of the speed of light. When the twin returns he will be younger than his brother because for him time slowed down during the trip.
This effect, called "time dilation," helps explain why the speed of light is the same no matter how fast you are going. As a traveler accelerates
time slows down for him. This, in turn, affects his measurements. "
It wouldn't matter what direction you are going in however. Clockwise, counterclockwise, it's still the same effect.
