the time will be 12 dec 2016.
why iam getting this problem ???
plz anyone can help me
That sounds more like a virus, when time is not locking in to the curent time it's usually a battery problem and it reverts to the bios date which would be a time some months or more prior to the date it was purchased.
Switching to 2016 sounds suspicious.
