The time immediately before step 1 feels like the appropriate creation time for the worker. If we can get a hook into step 1 put into the Web Workers spec, I can link directly to that definition. I'll file a bug on the editor.

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. - James On Tue, Apr 16, 2013 at 4:43 PM, Jatinder Mann <jmann@microsoft.com<mailto:jmann@microsoft.com>> wrote: I have uploaded High Resolution Time Level 2 specification [1], which now supports performance.now() method in the Web Workers context.

I think the other stuff gets tricky when you have shared workers. I guess that means we need to define the 0 value too. I'd vote that it's the worker creation time.

The real issue is whether we want to move the entire performance object, all the methods and attributes, or a subset of the performance object to Web Workers as well. If we feel the Timing specs may not make sense in Web Workers, we'll need to specifically exclude them. I think we should be able to make this change relatively quickly once we have consensus.

How hard would it be to add Web Workers to High Res Time? The first edition is already a recommendation, so I think we'd need to create a level 2 spec for it. Does anyone know how large of a change to the spec it'd be? Is it just a matter of adding one tag to the IDL? If so, it seems like we might be able to do it relatively quickly. Thanks, James
