system clock workaround

["Owen G. Emry" <oemry@patriot.net>]

My firewall machine (a trusty old 486 DX4) has a bios that doesn't like the 
year 2000.  It isn't a major problem but several things (e.g. make) 
complain, so is there an easy workaround?

I assume I can just set the real-time clock to, say, 1990, and have the 
internal clock set itself to the RTC + ten years on bootup.  What do I have 
to change to accomplish this, or is there a better solution altogether?

Thanks greatly,
