Run a trial version of an app in VirtualBox beyond trial time

...or Configuring time sync of VirtualBox.

Although not ADF related it worths posting.

Found excellent post by Serafim http://serafeimk.blogspot.com/2010/10/time-sync-virtualbox.html .
Just reposting his tips:

Prerequirements:
Host machine: Linux
Guest in VirtualBox also Linux

Tip:

• Close vm 
• Write VBoxManage setextradata [VMname] "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1" in order to desynchronize the host clock with the guest clock
•  Run vm and the trial program without complaining
• Restore sync VBoxManage setextradata [VMname] "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "0"

Thanx Serafim
