Running Guest OS with different date time than Host OS
This is really useful to run old software with time limitations without messing up with the Host OS date/time settings.

It’s easy to specify a time offset from the Host OS in microseconds. 

First get the vm name

VBoxManage list vms

Secondly apply the desired offset (example -1 year clock).

VBoxManage modifyvm "name in vm list" --biossystemtimeoffset -31536000000
