macppc time weirdness?

[joshua stein <jcs@rt.fm>]

can anyone else reproduce this on a -current macppc (or other
architectures):

jcs@vorsicht:~> date; sudo rdate -n ntp.dls.net; date
Fri Jan  2 11:51:28 CST 2004
Fri Jan  2 11:30:54 CST 2004
Fri Jan  2 11:51:28 CST 2004

jcs@vorsicht:~> rdate -np ntp.dls.net
Fri Jan  2 11:32:23 CST 2004
jcs@vorsicht:~> sudo date 1132
Fri Jan  2 11:32:00 CST 2004
Exit 2
jcs@vorsicht:~> date
Fri Jan  2 11:52:35 CST 2004

now if i try to set it far back it will go, but is still not
accurate:

jcs@vorsicht:~> date
Fri Jan  2 11:53:06 CST 2004
jcs@vorsicht:~> sudo date 1100
Fri Jan  2 11:00:00 CST 2004
Exit 2
jcs@vorsicht:~> date
Fri Jan  2 11:20:35 CST 2004

kern.securelevel is at 1.  this is on a powerbook g4 with a -current
kernel.  i have rdate trying to set the time at boot (rdate_flags
set to "-n ntp.dls.net") but it never sets the time correctly (or
gives any indication of a failure).
