Windows clock problem

Ubuntu like many other non-windows operating systems does support dual-booting because they have to. Windows 10, on the other hand, usually ships with settings that are not optimal for dual boot setups. This creates a couple of minor problems, one of which is Windows 10 displaying the wrong time when you switch from Ubuntu to Windows Windows 10, and even prior versions store the time as local time.
