Re: [dom] High resolution timing for events (#23)

Is there a way we can test uses of:

* `e.timeStamp - anyDate`
* `anyDate - e.timeStamp`
* `var d = e.timeStamp`, later: `anyDate - d` or `d - anyDate`

I'd be very very surprised if those patterns did not impact a non-trivial number of the top sites.
