[Q] clock in status bar frozen

Hi
My clock app stop working around 8:45PM and also my phone works slow during that period.
everything works well after 4:00 AM ....?
I notice my alarm don't work in between that time and also no time update on any widget or on status bar time..

During that time if i try to install any app from app store than it also not work they will stuck at installing and never

finish that installation process...Also my phone get hotter during that period and it use more battery power
like it use 30% battery in 2 hr

Once it pass 8:45 PM it stay that time on status bar unless you reboot phone and after reboot it works for 5 min

and then again get Frozen to last state...

I have two android device (One X+ , nexus 7 both root and unlocked bootloader and has stock ROM )both device

doing same thing.

I thought it's a malware or virus so I wipe my phone and put custom ROM on it but I still have that Problem in my

phone...?

So it might be any app that cause that problem or something else that trigger at certain time
I am totally confuse how can i solve this problem...?

Any one have that problem ...?
