Should be done in userland (its handled by init), and the kernel should 
not have to know about these kinds of things. Then again if things were so 
fubared that a process with the watchdog died, then you're not bound to be 
able to shutdown cleanly anyway.

Also should be done in userland, why would you need to have pretty printed 
time for anyway?
