NSLU2's clock is backed up by a battery. Have you tried setting the time 
manually either using date(1) or ntpdate(8)?

I suspect NetBSD and Linux encode the time slightly differently in the 
RTC (they probably use a different epoch) so until you set the time 
manually under NetBSD you will always see this message.
