This addon is just a clock.
I modified it from Simple Clock which was written by SlimWaffle.
If you want a larger clock that includes date, check into 'Simple Clock'.
I wanted something a bit more streamlined so I modifed it to be a Simpler Clock.
The clock will appear at the top left of the screen but you can move it wherever you like.

SimplerClock has the same functionality of Simple Clock.
