I have done this RTC with atmel 2051 but working fine, I think you are mistaking in the software somewhere, show your coding and schametic then can help you.

pls advice me

Lets see, 56 posts for the obscure TI MSP430F449, why did you pick TI for your work? You never get any code for it, see if there are TI forums.

I think sn_burki is right. It's probably a mistake in the code.
Can you post the code?
