I received this message via the UNIX-WIZARDS mailing list and it
looks like it was not distributed to TCP-IP. This is claimed to be
the official SUN patch for Sun OS 3.2, 3.3, 3.4, 3.5.

Sun Tech Support
There exists a problem for all Sun3 (68020) machines running SunOS
Releases 3.0-3.5, 4.0beta1, and all Sun4 (SPARC) machines running SunOS
Release Sys4-3.2 FCS and 4.0beta1.
As of Jan 1 00:00 1988, the clock routine in the kernel will put the
clock chip into an uncertain state if you attempt to set the date.
The visible effects of this is to 1) cause the message
WARNING: TOD clock not initialized -- CHECK AND RESET THE DATE!
to appear while booting vmunix, and to 2) cause the system date to start
to drift widely. Any attempts to actually *set* the date will have only a
temporary effect (i.e., the date you set will be good for about 30 seconds).
In order to solve this problem, you must patch both the kernel and system
Sun3 System Patch
Releases 3.2, 3.3, 3.4, 3.5
As root, run the follwing command:
echo 'resettodr+c0?i' | adb /vmunix - | grep reset
You should see the following printed out:
_resettodr+c0: bnes _resettodr+0xca
If you see instead:
_resettodr+c0: bnes _resettodr+0xce
the patch has already been applied to this system.
Proceed with the rest of the patch procedure anyway!
If you do not see either of these messages, go no further with this patch,
and please contact Sun Microsystems Customer Service.
If you do see either of those messages, then run, as root,
the following commands:
cp /sys/OBJ/clock.o /sys/OBJ/clock.o-
echo 'resettodr+c0?w 660c' | adb -w /sys/OBJ/clock.o
echo 'resettodr+c0?w 660c' | adb -w /vmunix
Reboot and then *set* the date.
If you build kernels for your system, also rebuild your kernel.
