lastModified Y2K solution

I have found a solution to my own problem (that I posted earlier today)
Here it is:

<script language="JavaScript">
<!-- 

var lmd = document.lastModified;
d1=Date.parse(lmd);

// this subtracts 8 hours from the current time
// to make it accountable for Pacific Standard Time
// the number for the time is represented in seconds

d2=d1-28800000;

// the following line of code adds 100 to the year
// to make the year 2000

d2+=3155673600000;

  // check if we have a valid date
  // before proceeding
  if(0 != (d2))
  {
    s = "" + new Date(d2);
  }
document.write( 
  "This page was updated on " + s);


// -->
</script>
