how to count server response time from client ??

[Leon]

Client send--> network --> Server --> Server Process --> Server Response --> 
network --> Client receive
                                           |------------------------------------------------|
|----------------------------|           Server process response time
    packet arrive server time 
|---------------------------|
                                                                             
                                            packet arrive client time
So I want get server time clock different from client.
