If there is any way where I can see time stamps for all incoming messages then please let me know. It will be a real helpful for me as it is urgent to me.

I am waiting to see any response.

Thanks

Can any body tell me if this is correct way to send time stamp while sending a message
var msg = $msg({to: sendjid, type: 'chat',id: 'ping1',stamp: '2012-11-16T23:08:25Z'})
.c('body').t(text);
alert(msg);
Arthur.connection.send(msg);

will this time stamp is the correct time stamp for receiving a incoming message?

If the message was not delayed you can use wall clock time. Time is not normally stamped since it's assumed to be near real-time. The exceptions to this are offline messages and chat history, etc, which get stamped with the <delay> tag.
