Sorry guys I took this off topic.
That said, not having done a Call Director yet I didn't realize it was a VM on MSL?. I assumed (we all know where that leads you) that they had ported the 3300 to Linux native. As a VM, I would think it would only read the time from the host at boot - although with time shareing in VM's I'm not a 100% on that. I would guess that it depends on how the virtualization layer handles the time. I'll have to play with VMWare and XEN both so see what happens in that area.
