Is "speed of light" synonymous with "speed of time"?

Judging from virtually every sci-fi movie I've seen on the concept, accelerating faster than the speed of light reversed time and the aging process, but if that were true, then light itself would be ageless and tachyons would have an imaginary age since they theoretically travel faster than light speed. I'm no physicist, but I thought that accelerating faster than light speed would rip apart atomic bonds or something like that, I dunno...
