What's the problem this feature will solve?

When parsing pytest report (in my case --reportlog file) TestReport objects only contain duration information. I'm missing start and stop timestamps to be able to correlate test results with external events.

Describe the solution you'd like

TestReport objects should have .start and .stop attributes set, which can easily be copied from CallInfo objects in TestReport.from_item_and_call

Alternative Solutions

I considered adding it to pytest-reportlog here - pytest-dev/pytest-reportlog#22, but we agreed that core pytest is a better place for such change.
