670558 - Different reference time for DOM events and mozRequestAnimationFrame

Status: RESOLVED DUPLICATE of bug 77992

(Core :: DOM: Events, defect)

Description

[u419766]

Attachment: referencetime.html

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0) Gecko/20100101 Firefox/6.0
Build ID: 20110705195857

Steps to reproduce:

- open attached file in Browser with Web Console opened
- Press a key to fire a keypress event
- compare the timestamps logged to the console


Actual results:

Both timestamps have a large deviation, as if they use different reference times (epoch). The MDN documentation defines both timestams as milliseconds since the epoch. I would expect the epoch to be the same in both cases.


Expected results:

Both timestamps should have a small deviation.

[Boris Zbarsky [:bzbarsky]]

DOM event .timeStamp are completely bogus in Gecko.  e.timeStamp doesn't even have the same _units_ for different events, much less the same epoch time.

The MDN documentation in this case sounds like wishful thinking more than documentation...
