RTC for M41T83 high resolution

I'm looking at controlling the M41T83 or M41T82 Real time clock chips via I2C.
I was wondering if any one has made an attempt to control and read from this clock. I am familiar and have used other libraries for other clocks and they seem to work fine. It appears i can make writes to this clock and read from it, but the output doesnt seem to increment. :o

Does this help?
