Using API/EDX Code How to Find the Start/End Time of Tasks

[#1]

I have successfully completed couple of .Net applications that assigns and revokes DOC CAL licenses using QV API. I am trying to create another .net app where it will pull the Start and End time of all the tasks in QMC. But I am unable to find any supporting code or Class for it. Can anyone please help?

Here is what I am assuming:

string QMSURL = "http://localhost:4799/QMS/Service";

            string Taskname = "Reload of Golf Quest.qvw";

            string Taskpassword = "secret";

           QMSClient Client;

            Client = new QMSClient("BasicHttpBinding_IQMS", QMSURL);

            string key = Client.GetTimeLimitedServiceKey();

            ServiceKeyClientMessageInspector.ServiceKey = key;

--(My Assumptions)

            Client.Task.CurrentState

            Client.Task.StartTime();

            Client.Task.EndTime();

--(My Assumptions End)

Is there any such thing available at API level?

Thank you very much.
