Easy way

Download attached .reg file, run it and reboot to linux and then back to windows

Hard Way

To fix it, just hit Start and type regedit.exe in the search box. Hit Enter and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation. Right click anywhere in the right pane and hit New > DWORD (32-bit) Value. Name it RealTimeIsUniversal, then double click on it and give it a value of 1.

Lastly, reboot into linux, then reboot back into Windows.

You should now notice that your clock actually displays the correct time.
