something like (nice suggestion avoiding the global, @csuwldcat):

````javascript
var _log = console.log;
console.log = function() {
  arguments[0] = new Date().toISOString() + ': ' + arguments[0];
  _log.apply(null, arguments)
}
````

@seanmonstar I think this covers the multiple arguments and string interpolation cases. Unfortunately, I don't think this would handle console.log({foo: 'bar'}) properly, we'd wind up with "2013-07-01T22:43:50.896Z: [object Object]" instead of "2013-07-01T22:43:50.896Z: {foo: 'bar'}".

I guess the lesson here is not to screw around with built-ins? ;-)
