Seawas kguy!
Have you installed packages as well?
M-x find-function RET display-time RET (with all packages installed :-)
finds it in
xemacs-packages\lisp\time\time.el
so it's the time package.
After I done this:
XEmacs <= 21.1
Options->Manage Packages->Add Download 
Site->xemacs.org
Options->Manage Packages->List & Install
XEmacs >= 21.4
Tools->Packages->Add Download 
Site->xemacs.org
Tools->Packages->List & Install
(package-get-package-provider 'time)
will confirm you this:
(time "1.12")
It's the time package you need to have installed.
Hope this helps,
Adrian
