The Test Reports shows incorrect startTime and endTime when test suite is selected.
It shows correctly when a test case is selected from Suite/Test List in the parameters panel.
Please, note that the startTime and endTime in the reports are not the From and To parameters selected but the actual execution time of test case/test suite.
There is an issue in the SQL query where we are returning the startTIme and endTime as 0 for a test suite.
There is a patch that fixes this issue.
If you are facing this behavior, please open a support ticket and reference DE378744. We will be happy to provide you the patch if it matches your issue.
