If you're doing this to defeat a program's security or licensing scheme, let
me warn you that there are many ways this could be detected. Inconsistencies
in different time functions, filesystem times that are way ahead of system
time, times built into networking protocols (and thus received from remote
machines), detection of times before other run time, and so on.
