I have below postman script to validate API response time.

pm.test("Response time is greater than 1000ms", function () {
pm.expect(pm.response.responseTime).to.be.below(1000);});

But my test is validating the total time taken for like DNS lookup, Handshake,Transfer Start etc.

Is there any way to validate postman api call Transfer Start time only as a part of postmam scripts test?
