Time Machine for VirtualBox

Hi there,
I have created a small program for VirtualBox (Windows) to make it easier to launch a VM setting the BIOS time to a specific date & time.
You might know there is a setting (--biossystemtimeoffset) which has to be calculated between current time and the wanted bios time.

VBoxManage setextradata "TimeMachineVM" VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" 1
VBoxManage modifyvm "TimeMachineVM" --biossystemtimeoffset -1760542000

My software makes it easy to select a specific date & time and to launch the VM using this date & time.
It also includes a feature to synchronize the date & time of a directory, could be a VBox Shared Folder.

You can download the software from here:
fundme.link/VBTimeMachine/

Would be good to get feedback and bug reports etc.

Thanks!
