content: By default, Windows stores the clock in local time while every other OS on the planet set it to UTC. XP even managed to break entirely if you set it to use a UTC hardware clock! Windows 7 actually works with it, so imagine later versions should as well(though Windows 7 has had the odd bug with it). If you want to take the leap, set [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation] "RealTimeIsUniversal"=dword:00000001
