Messages born expired

                 Key: AMQ-2587
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker, JMS client
    Affects Versions: 5.3.0
         Environment: Windows XP, Sun Java 1.6u18
            Reporter: Nacho Vargas

Under some circumstances, messages are born already expired. To reproduce it, you need two
computers, a "server" and a "client".

1. Set the current time in the client as appropiate in your time zone, say it is 11:00am.
2. Set the current time in the server as a few minutes after the real current time, say 11:10am.
3. Run an ActiveMQ broker in the server.
4. Run an ActiveMQ producer in the client.
5. Send a message from the producer with a short time to live, say 5 seconds.
6. The message is inmediately marked as "expired" and it is not delivered to consumer(s).

I have been using ActiveMQ 4.1.1 for a couple of years and this has never been an issue. I
have recently moved to ActiveMQ 5.3.0 and I have found this issue.

A messaging system should *NOT* assume that clocks in every computer in the network are synchronized.
