In the VMware Tools control panel, the time synchronization checkbox is unselected, but you may experience these symptoms:
When you suspend a virtual machine, the next time you resume that virtual machine it synchronizes the time to adjust it to the host.
Time is resynchronized when you migrate the virtual machine using vMotion, take a snapshot, restore to a snapshot, shrink the virtual disk, or restart the VMware Tools service in the virtual machine (including rebooting the virtual machine).
Sorry if I'm dense, but I assume when you power up a VM, the host's time is given to the VM. Is that correct?
