Forward or backward?

Forward is no real problem.  Apps will get the new time when the call
time().  Apps that look at time deltas will see a bigger time delta
than normal and cron will skip entries that were included in the time
you skipped.

Backward a bit more of a problem.  The main issue is that your file
times will be in the future.  Things like "make" and "modprobe" don't
like it.  You would need fix the file times (mtime, ctime, atime) for
those that are in the future.
