Subject Re: Message Source time vs Receive time
Date Tue, 03 Mar 2015 19:43:04 GMT
I suspect one issue with figuring out the time a message was
received by a subscriber is that an efficient client will typically
buffer up messages.

The page

http://activemq.apache.org/activemq-message-properties.html

says that JMSTimestamp is the time the message was sent,
and I believe that means "sent by the producer."  Given the
fact that these messages are typically being sent by multi-threaded
processes and that even networking delays might be an issue,
I have to imagine it's only guide as to the ordering of when messages
were actually sent to the broker.

Have you already seen the topics on exclusive consumer and message groups?
