#1734422 Fix the time difference between osx86 and Windows in multiboot setups.

Fix the time difference between osx86 and Windows in multiboot setups.Preface: When you installed osx86, dual-booting with Windows, you might notice your clock changed one or several hours when booting Windows right after osx86 and vice versa. Why does this happen? Macs save the universal time (aka UTC) of the world to the BIOS instead of the local time of the time zone you live in (aka localtime). And Windows assumes the BIOS time is the local time. Wait, what? For instance, while running osx86, the clock on your screen could read 4:02pm (local time), but in your BIOS, the time could be 2:02pm (universal time). And if you would reboot to Windows, the clock in the taskbar will read 2:02pm because Windows reads the time from the BIOS upon booting and assumes it's the local time. How can we fix this? The best way to fix this, in my opinion, is to make an adjustment to the osx86 installation, and not to your Windows OS because that's not where the problem is located, and on the othe...
