SYMPTOMS
When you use Microsoft Message Queuing (also known as MSMQ) to send a message to a BizTalk Message Queuing Adapter (MSMQT) receive port on a computer that is running Microsoft BizTalk Server 2004, delays of more than five minutes may occur before the server responds.



CAUSE
This problem occurs because the difference between the local time and Coordinated Universal Time (Greenwich Mean Time) is not an exact multiple of 60 minutes. For example, India is 5 hours and 30 minutes ahead of Coordinated Universal Time. In this case, the message box conversion from Coordinated Universal Time to local time does not consider the minute part of the time. MSMQT uses timer messages to periodically send order acknowledgements (OrderACK). Because of the time conversion problem, the timers are not started in the first 30 minutes of any hour. Therefore, the acknowledgements are not sent.
