Question 2:
 
does this product feature real time? For example disconnect the power supply, and after its inclusion is not necessary to re-configure (to set the time and date) for this product?
 
Yes, the controller can store the data when power off and power on again, you do not need to reset it.
 
Question 3:
 
there is two power sockets (DC jack and screw), could I connect two power supply at the same time to improve the power , to connect more lights ?
 
Sorry, connect two power supply to one controller at the same time is not allowed, it will damage the controller, or even break your power supply, PLEASE DO NOT DO THIS, thanks.
