That's not an error.  The kernel's telling you what it thinks of
itself... ;-) I'm not sure of the current state of the affair, but
NetBSD/mac68k has been known to lose the time due to lost (uncaught)
clock interrupts.  You won't notice it unless you keep the system
running actually doing something for a while, like a day or so.
