UTC in Microsoft Windows
To dual boot with Windows, it is recommended to configure Windows to use UTC, rather than Linux to use localtime. (Windows by default uses localtime)
It can be done by a simple registry fix: Open regedit and add a DWORD value with hexadecimal value 1 to the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal
You can do this from an Administrator Command Prompt running:
C:\>reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f
