Folks,

I just wanted to report that the Web Performance group talked about the
high performance times requirement yesterday [1].

We've been changing our specs recently to allow sub-milliseconds:
[[
Throughout this work, time is measured in sub-millisecond resolution
since the start of the navigation of the root document, as recorded in
the navigationStart attribute. For example, a timestamp value of 1.5
would be 1.5 milliseconds since the start of the navigation of the root
document.
]]
http://dvcs.w3.org/hg/webperf/raw-file/tip/specs/PerformanceTimeline/Overview.html

However, we do realize that the current is still vague and that
developers would probably want more guarantees on what
"sub-milliseconds" means.

We expect to put a short document together within two weeks on that.
I'll send a pointer to it.

Hopefully, that will address the use case. If it does not, let us know.

Philippe
