Greetings!
Currently we do not support the installation of VMWare Tools on an SPC 2 appliance.
We also don't allow self management of the appliance, other than those items that have been programed in the Web Console, such as checking for product updates. We are working to add some self-help utilities, and are exploring the possibility of installing a subset of the VMWare Tools, but don't currently have a time frame for this to occur.
The SPC product is a security appliance, which has been hardened to prevent attacks. We have multiple Symantec Products "under the hood" working together to provide the optimal experience.
We actively monitor OS updates from Microsoft, and whitelist them, then install them through our nightly update process.
If you would like assistance setting the time server, please send me a private message with your contact information and I will assist you, or assign one of our technician's to do so.
Regards.
