title: VMWare how to prevent a virtual machine from updating its date and time
body: <p>I want to know how virtual machines (VMWare) updates their date and time and how to disable this; because i noticed that even if i suspend/shutdown a virtual machine for a year when i'll turn it on again, it will have the right time and date. </p>
  
  <p>For physical machines i know there is a little battery inside the Central Unit fixed on the Motherboard that helps to keep date when the computer is turned off and disconnected from powersupply. But what about virtual machines how do they keep their time ? and how can I forbid that ?</p>
