Ok, I finally got the clock that I want, but in a very cumbersome and bloated way.
First, I had to create a new file, /usr/share/applications/screensavers/gltime.desktop.
Exec=/usr/lib/xscreensaver/gltext -root -text "%I:%M:%S %p\n%a %b %d, %Y"
Comment=Displays a few lines of text spinning around in a solid 3D font. The te$
Next, I had to install xscreensaver-data-extra which includes a long list of other screensavers that I really didn't want and includes these packages:
libjpeg-progs libnetpbm10 netpbm xscreensaver-data-extra
The cumbersome part about all of this is that whenever I changed the gltime.desktop file I had to uninstall, then reinstall xscreensaver-data-extra. I also had to log out then log back in for the changes to take effect.
There's got to be a better way of accomplishing the same thing with out the bloat of all the other screensavers and without the hassle of reinstall and relogging ...
