// CHANGELOG
//  v0.3: David made it work again with newest woot layouts (12 Oct 2009)
//  v0.2: fixed themage issues for shirt.woot and wine.woot (20 Jun 2008)
//  v0.1a: initial release (18 Jun 2008)
// FUTURE PLANS
//  - rewrite extractWootLink() and getTitle() into one function so as to
//    limit regular expression matching.
//  - consolidate functions into a common library for use with my other
//    sellout.woot script (http://userscripts.org/scripts/show/13074)

// javascript lacks everything php has in the date/time methods department which
// is why this function is here.  basically this gets the current date of the
// woot.com servers (which are located in central time, GMT-600)
function getTheDate() { 
  var d=new Date();
  var month=new Array(12); 
  var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
  var nd = new Date(utc + (3600000*-5));
  month[0]="JAN";
  month[1]="FEB";
  month[2]="MAR";
  month[3]="APR";
  month[4]="MAY";
  month[5]="JUN";
  month[6]="JUL";
  month[7]="AUG";
  month[8]="SEP";
  month[9]="OCT";
  month[10]="NOV";
  month[11]="DEC";
