date & time stopped when machine is in saved state

Hi, I'd like to ask You how can I set up my VirtualBox to synchronize VirtualOS Date/Time with HostOS date/time

When I save state of my virtual machine and lately restore it, the time does not changed. And then the virtual time is invalid.
When I use MS Virtual PC this problem does not happen. It allways synchronize both date/times.

Thank You in advance,
Tom

When you save the VM, the whole VM state is frozen. After restoring the VM, the previous VM state is reloaded and this includes the time at the point when the VM was saved. When you installed the guest additions and you are using VBox 3.2.10 (make sure to use the 3.2.10 additions as well), then the guest time should synchronize immediately with the host time after the VM is restored from a saved state. Without guest additions there is no time synchronization at all and the guest time can drift away. With guest additions older than 3.2.10 the synchronization after restoring the VM is done very slowly.

And MS VPC works the same way.
