I have two operating systems in my machine: Windows 7 and Ubuntu 16.04, dual booted. After upgrading my ubuntu to 16.04 version from 15.10, I am facing a strange problem. When I open Ubuntu, time advances 5.30 hours(I am from India and our timezone is +5.30GMT). Suppose I correct it, then when I logs back in Windows, the time decreased by 5.40 hours.
How to fix it? There might be some installation problem at the time of upgrading.
