Hi!
Check real time clock 32kHz with frequency counter. If there is tolerance greater than 0.5%, replace crystal. It may be capacitance from PCB near crystal. Clean very good pads where crystal is soldered and check small capacitors in crystal circuit. For more info see shematic diagrams. Mail me for results. I have had some bad 8210 with same problems, but now they are ok.
