I want to drive led with PWM capability of the Arduino, it's OK i know i can do that.
But i want light up smoothly at 12h00 and down smoothly at 20h00, how i can do that? Perhaps not?

The Arduino does not know what time it is. But you can do 2 things :
Use a computer with some software to send a signal to the Arduino on the correct times.
Or use a real time clock IC, example here : http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1191209057/15
