hijacking Javascript console.log revamped with StackTrace (just Google Chrome)

gistfile1.js

// usage as usual: console.log('inside coolFunc',this,arguments);

if (typeof console !== "undefined") {
  console.logJack = console.log;
  window.log={}
  window.log.history = window.log.history || {};   // store logs to a global history for reference
  console.log=function(){
    var timestamp= (new Date); //create a timestamp of the log
    var millis=timestamp.getTime();
    var readableString=timestamp.toUTCString();
    var stack=new Error().stack; //save a stacktrace for Google Chrome
    var array=Array.prototype.slice.call(arguments);
    var args={arguments:array, stackTrace:stack}
    log.history[millis]=args; //save everything to the log
    console.logJack(readableString, arguments, millis); //call the original log function with a timestamp
  }
}

Looks promising, but your'e not passing the stack trace anywhere into the orig. console log?
