How do we test this?

[Vsevolod Vlasov]

This is tested in fast/dom/webtiming*.html layout tests.
After landing of http://codereview.chromium.org/6823006/ these tests would fail, unless this patch is also landed.

Ideally the ChagneLog would contain this information. :)

You probably should do the same for the secureConnection timers above and for the responseEnd below.

secureConnection: "If this attribute is available but HTTPS is not used, this attribute must return zero.", so zero is correct.
respondEnd is filled from documentLoadTiming, not resourceLoadTiming, so its value is correct as well.

Thanks for taking care of this.
