Time JMS message lives on the topic

[Yevgeniy Furman]

I would to find out how long the message has been on a topic before a client read it.

Specifically:
I have 3 machines with the different times (producer, JMS Server and Consumer).

Producer sent a message to JMS at 11:00 (producer time)
the client read the message from JMS at 11:01.

What I would like to do is to get this information in terms of JMS Server time so that I can say for sure that my messages sat on the queue/topic for exactly X milliseconds.
Please help

Look at:
http://docs.oracle.com/javaee/6/api/javax/jms/Message.html#getJMSTimestamp%28%29

And try that:

public onMessage(Message m) {
    long time = System.currentTimeInMillis() - m.getJMSTimestamp();
}
