body: <p>How to change system default date time on Debian permanently?</p>
  
  <p>I tried following command</p>
  
  <pre><code># date --set="12 MAY 2012 12:12:12 PM"
  
  # hwclock --systoh
  </code></pre>
  
  <p>But date-time is getting changed temporary. </p>
  
  <p>After few seconds, current date is popping again.</p>
  
  <p>Did I miss something?</p>
  
  <p>Update</p>
  
  <p>System is guest OS on virtual box, where ntp is not enabled. </p>
  
  <p>While ntp is enabled in host OS. </p>
