event.timeStamp does not function correctly

[bjmw]

From ​http://api.jquery.com/event.timeStamp/ - event.timeStamp should record the difference in milliseconds between the time the browser created the event and January 1, 1970.

Up to version 1.6.4, event.timeStamp correctly records, tested on both FF8 and IE8.

For versions 1.7 and 1.7.1, the timeStamp does not correctly record. In FF8, the number is much lower and IE8, "undefined" is returned.
