Was doing some y2k testing on my machine, and found the
following problem:

[root@balrog /root]# date
Sun Feb 21 06:15:38 PST 1999
[root@balrog /root]# /etc/rc.d/init.d/xntpd stop
Shutting down xntpd:
[root@balrog /root]# date -s "Jan 1 00:00:00 2000"
Sat Jan  1 00:00:00 PST 2000
[root@balrog /root]# /usr/sbin/ntpdate tock.usnogps.navy.mil
 1 Jan 00:00:09 ntpdate[2359]: Can't adjust the time of day:
Invalid argument
[root@balrog /root]# date -s "Jan 1 00:00:00 1999"
Fri Jan  1 00:00:00 PST 1999
[root@balrog /root]# /usr/sbin/ntpdate tock.usnogps.navy.mil
21 Feb 06:16:21 ntpdate[2361]: step time server

Looks like ntpdate has an issue with the date format. I'll
try to chase it down tomorrow - though if someone want to
contact me, that would be fine, too.

I suspect the bug is valid on all architectures, though I'm
filing it for i386 because that's all I have to test on.

Ooh, my bad. Ntpdate actually has a problem with ANY date more than
approx 16 hours in the future.  I'll go back to reading the sources
now.  I'll followup shortly.  <sheepish grin>
