I most certainly can. Time slows down as your approach the speed of light. This is very well-understood by relativistic effects. Where an hour passes for you, a minute may pass for me depending on how fast I am going relative to the speed of light. So while one day may pass for me, I may effectively jump 100 years into the future. Einstein wasn't kidding when he said all of this stuff.
I travel into the future all the time!
With most of the emphasis on performance and stability, this was probably the one "feature" I was looking forward to with Snow Leopard. At $29 I'll still upgrade. Grand Central and OpenCL sound fairly impressive but I was really looking forward to a file system that never needed to be upgraded... I guess I'll keep on waiting.
