Symptom:
Display is off during Display On Duration of device near midnight.

Conditions:
1. Set power save parameters in device near midnight. (Duration should pass midnight)
e.g.   Display on time = 23:00
	   Display on duration = 06:00
	   (So, the display should be on from time 23:00 to 6 hours more)
	   
2. Change device time locally  and set it in between On duration.
(eg. manually set time after midnight like 00:10  or 01:00 . Set time should be in On duration )

Note : 
If manually time is set after midnight(i.e. 01:05) then device will go in Power save mode. (step 2)
But if time is set before midnight (i.e. 11:57)  then device will show be only DIM .
