Time synchronization of the host and guest OS does not turn off?

Question

virtual box

I did the following on the command line:

VBoxManage setextradata <YOUR_VM_NAME> "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" 1

VBoxManage setextradata <YOUR_VM_NAME> "VBoxInternal/TM/TSCTiedToExecution" 1

In the guest OS,

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VBoxService

in meaning

ImagePath

indicated

system32\VBoxService.exe --disable-timesync

And as a result, after rebooting the guest OS, the time is not synchronized, and after shutting down and turning it on again, the time is again taken from the host.
Is it really possible to solve it?

Answer 1

and whether time undertakes from a host? Is time synchronization with external servers disabled in the OS itself in the virtual machine?
