Messages are not sent or received if you change the system time during transaction processing
Article ID: 814116 - View products that this article applies to.
If you move the system time ahead during transaction processing, Microsoft Message Queuing, also known as MSMQ, 2.0 may stop sending and receiving messages.
This problem occurs because the Message Queuing 2.0 scheduler wakes up to perform tasks according to the most urgent task. If the system clock is moved ahead after the wake up, the queue manager does not adjust the wake up. The wake up is never reached, because it is earlier than the current time.

The Message Queuing 2.0 Scheduler saves the next wake up time. A new task determines the latest time that the wake up can be performed (timeout). If the timeout is earlier than the wake up time, the system adjusts the wake up accordingly. However, if the system clock is moved ahead after the wake up time is set, the queue manager does not adjust the wake up time. The wake up is never reached, because it is earlier than current time.
The following is the Message Queuing 2.0 wake up algorithm:
