how can i read the exact test execution time with edge using csv.php ?

with other browsers I read test results with /csv.php?test=“test id”
this returns 91 data fields and there are two of them (‘date’ and ‘time’),
which allow me to know the exact time of the test run,
information I can insert into the x-axis of a graph.

in tests performed with edge, instead, the fields returned by csv.php are 68,
and there is, among these, no information of the execution time.

I ask for help or suggestions

Many thanks
