It is quite clever though.
It seems to be :
"Set a time, press Go, and the cube will be solved in exactly that time".
So, you can set exactly how long you want to be mesmerised for, staring a self-solving cube. Very relaxing, IMO
Edit: Oh - and the page even calls itself a Stopwatch. I missed that.
