Adding a custom 'seconds' function on to Number in JavaScript

gistfile1.txt

> Number.prototype.seconds = function(){ return this * 1000 }
=> function (){ return this * 1000 }

//time to get funky

function Days(num){
  this.num = num;
}

Days.prototype = { 
  get ago(){
    return new Date((new Date()).getTime() - (this.num*24*60*60*1000));
  },
  get from_now(){
    return new Date((new Date()).getTime() + (this.num*24*60*60*1000));
  }
}

Number.prototype.__defineGetter__("days", function(){return new Days(this)});
Number.prototype.__defineGetter__("day", function(){return new Days(this)});

result:

> 1..day.ago
=> Sat May 21 2011 21:15:19 GMT+1000 (EST)

Pity some "browsers" don't support getters and setters.
