You could just try

  gst-launch-0.10 videotestsrc ! timeoverlay ! ffmpegcolorspace !
ximagesink
  gst-launch-0.10 videotestsrc ! clockoverlay ! ffmpegcolorspace !
ximagesink

and see if you can spot the difference yourself. The documentation at

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-clockoverlay.html
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-timeoverlay.html

(linked from http://gstreamer.freedesktop.org/documentation/) might also
be useful.

PS: the difference is that clockoverlay overlays the wall clock time,
while timeoverlay overlays the time as found as timestamps on buffers
passing through.
