# Description:  This script will be used to resolve an issue with VMWare where the VMWare Tools cause a
#                   time sync with the host.  If the host has an incorrect time it will knock the time out of
#                   sync on the guest.  To resolve this issue some text entires need to be made to the VMX
#                   fix.  This is detailed here:
