Implementing the web timing spec

Hi everyone,

there's a specification for exposing detailed timing information of web 
page elements via the DOM:
http://dev.w3.org/2006/webapi/WebTiming/

Some people here would like to implement it in Firefox. The reason for 
exposing it via the DOM is to gather actual concrete end-user timings; 
other approaches don't allow that (also not all of this timing data is 
currently available to extensions).

The idea is to change the spec a bit to limit the number of elements on 
which this data is exposed, probably to drop the Ticks interface, etc.

Would people agree this is useful, and in particular, would the DOM 
peers be willing to accept patches to implement this spec?

Chromium is implementing this spec as well 
(https://lists.webkit.org/pipermail/webkit-dev/2009-October/010382.html). 
For a bit of discussion on the spec, see the thread at
