Linux mint VM's automatically sychronize the date and time with the host when resuming from a suspend, but vectorlinux (slackware) do not. Settings are the same in the .vmx's except the guestOS. Both have vmware tools installed. Typing vmware-toolbox shows the "time synchronization" as enabled. What else could be wrong?
Found what the issue was with vectorlinux time synchronization. You must enable the vmware-guestd service - it is not enabled by default. Under
Vector Control Center - SERVICE - Services - Graphical user interface desktop - vmware-tools: vmware-tools daemon
