What is Duration, startTime and endTime in trx report?

[vadim-96]

Steps to reproduce

Just generate trx file with following command: dotnet test --filter Category=Test --logger:trx;LogFileName=results.trx

Environment

• Windows 10 x64, NET 5.0, Visual Studio Community 16.8.4
• SpecFlow 3.6.23, SpecFlow.Tools.MsBuild.Generation 3.6.23, SpecFlow.xUnit 3.6.23, xunit.runner.visualstudio 2.4.3, Microsoft.NET.Test.Sdk 16.8.3, FluentAssertions 5.10.3

In trx file I can see following sections: duration, startTime, endTime. I couldn't figure out how the time is calculated?

I found these fields in code: https://github.com/microsoft/testfx/blob/ec18af6f90c272f68f48d9d0b94c71b8e276c7a0/src/Adapter/MSTest.CoreAdapter/Execution/TestExecutionManager.cs#L376

Start time and End time are set to current timestamp when they are not provided by the adapter. XUnit does not provide that information, it only provides duration, so the start and end time timestamps are incorrect. We could possibly calculate start time from duration, but then it would be hard to distinguish from the case where the adapter provided correct start time and incorrect duration. Or incorrect start time and correct duration, in both cases the numbers would not add up.
