RTC is not running

I have written a drivers for DS32B35 RTC chip, I am able to update the date and time of RTC and it is preserving between the reboot. the problem is It is not updating the time . If i set it to one time it is still in the same state even after a day.

 

any idea why?

I have configure the status/control bits properly to turn it on.

 

Thanks
