Here's an LD_PRELOAD shared library that will do the trick... just
export the environment variable FAKETIME with the time that you'd
like, and then export the LD_PRELOAD environment variable to point
that the faketime.so library, and then execute your program. All
programs that have these two environment variables set will have their
time faked out accordingly.
