Steps to reproduce the problem:
Right now RequestFinishedInfo.Metrics only returns getTtfbMs, getTotalTimeMs, getSentByteCount and getReceivedByteCount in long values, it returns other values such as getDnsStart and getSslEnd in java.util.Date class, it's implementation is creating a Date class from a long field value.

We are more interested in how long it takes to do the dns resolution,  setup ssl, sending the request, getting the response, etc.

Right now to get Dns time, we need to call getDnsEnd and getDnsStart and compare two Date instances, it's better to compare two internal fields directly and returns the long value or zero if the socket is re-used.

Please consider adding these functions directly.

What is the expected behavior?

nothing, just feature suggest.
