Revolutionary Clock Installation
To make the installation easier, I have uploaded the script files to our custom PPA. To install Revolutionary Clock on Ubuntu 12.04/11.10 or Linux Mint 13, open the terminal and issue these commands:
sudo add-apt-repository ppa:upubuntu-com/conky
sudo apt-get update
sudo apt-get install revolutionary-clock
You can now start Revolutionary Clock via the Unity dash:
To install this script manually so that you start only certain clocks, you can refer to this page.
