Re: [HighResTime] Web Worker support

In the line:

For a shared worker<http://www.w3.org/TR/workers/#shared-workers-and-the-sharedworkerglobalscope-interface>,
the *time origin* must be equal to the time of creation of the shared
worker.

What is the definition of 'creation of the shared worker'?  I could imagine
in the processing model:

http://www.whatwg.org/specs/web-apps/current-work/multipage/workers.html#processing-model-6

that this could be interpreted as a time before or after steps 1, 4, 5, or
just before step 8.  I think it needs a better normative reference,
although the concept seems fine.
