You don't need to rebuild your kernel; there's nothing wrong with it. The
memory that shows up as "in use" is being used by the kernel to cache
things such as disk accesses. It is available for any program that needs
it, though. The kernel will simply re-adjust its caches so it can
allocate memory to other programs that need it.

I doubt it. Remember, Linux is used extensively in server environments
where it is left on for weeks or months at a time. It would be
unacceptable if the clock didn't keep accurate time on these machines.
How far off is your clock getting?
If you're on a network, you can run xntp to synchronize you clock with
xntp servers over the network. This will keep your clock accurate to
within a few milliseconds or something. The list of public xntp servers
is installed with the xntp package.
