why these codes don't work ,about DS1244's Phantom Real-Time Clocks !

hi:
/* these codes are about DS1244. I can make sure the circuit is correct
because I can access data from DS1244 correct . but I can't use Phantom Real-Time Clocks.
when I try to get the data of Time register, I get all zero ,Thank you for you reply*/
