Move launcher from side to bottom
Assuming you don't want to install a totally new desktop, you can simply move the launcher from the side to the bottom with this command:
gsettings set com.canonical.Unity.Launcher launcher-position bottom
Use Conky to display time
As mentioned in comments the time is most likely created using Conky. You can find many examples on setting up Conky in Ubuntu Forums. Here is my humble Conky display:
Someone commented in jest about making Conky run at 60Hz. I thought it would be fun to try so changed the refresh rate from .75 times per second to .0167 times per second which is about 60 Hz or 60 Frames Per Second:
Sorry about the hole in the middle it normally has nVidia GPU information but I've booted with Intel iGPU and am trying to find out how to get performance statistics on it.
Notice how Conky CPU percentage jumps from .5% at normal speed to about 5% at 60Hz speed. Also note my browser doesn't refresh the screen as fast as the .gif that is running (it's about 3 to 4 times slower?).
