[plug] ntp and gnome2 time sync problem

[William Kenworthy]

Here's a weird one ... ntpd runs fine *until* I log into gnome2 ... then
all servers show rejected until I log out, when ntp syncs up again.  The
ntp config file works fine on two similar installs (gentoo/gnome2). 
ntpd is started during init as per usual, or via command line: results
are the same.

What mechanism can cause this?  Something gnome2 is changing on login? 
I have no error messages or useful info from ntpd or logs.
