Microsoft's primary NPS server and the BIOS clock are two distinct clocks, and Windows occasionally keeps switching back to the BIOS clock. This can be very unpleasant, especially if you are using applications that have severe timing requirements.
Ignoring the hardware clock
To ignore the hardware clock you have to run the following command
reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f
This will add a registry key to ignore the clock, by doing this the VPS will jump back to it's own time server.
We recommend to setup your own NPS server of your choice to sync the time with your VPS.
