I have two hard disks in my PC (160 GB & 80 GB). The 160 GB hard disk has Ubuntu 12.04 installed in it while the 80 GB hard disk has Windows XP. I added the 80 GB hard disk just a few days ago, before which I was using only the hard disk with Ubuntu.
Before the addition of the second hard disk, the Time & Date settings worked fine in Ubuntu(It showed the correct time and date every time I booted my PC). But now, whenever I boot my system, the time is wrong. Even if I set it correctly it becomes wrong the next time I boot my PC.
What is causing this problem and how can I resolve it?
