Summary0006675: Add Registry Entry to set Windows RTC to UTC
DescriptionBy default, Windows assumes that the system's Real-Time Clock (RTC) is set to local time. In our case we should use Coordinated Universal Time (UTC) instead. This behavior can be adjusted by adding the following registry entry:

Registry Key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001

Values:
    0 = The BIOS clock is interpreted as local time (default)
    1 = The BIOS clock is interpreted as UTC
