The Clock Plugins Manager
A full menu bar manager such as Barsoom, is too much for you.
You simply want to have The Clock on the right side of your menu bar.
The Clock Plugins Manager is for you.
Simply install the plugin. The Clock will always be on the left of your Spotlight icon.
NOTE for macOS Sierra users, The Clock Special Plugins is not macOS Sierra compatible. Just remove it if already installed. macOS Sierra offer natively the feature to position The Clock on the right side by simple cmd+drag action.
