The PROPID_M_ARRIVEDTIME property is attached to the message by MSMQ. The arrival time returned is the number of seconds elapsed since midnight (00:00:00), January 1, 1970 (Coordinated Universal time) according to the system clock.

To retrieve the arrived time of a message, specify PROPID_M_ARRIVEDTIME in the MQMSGPROPSstructure. Then call MQReceiveMessageand examine the returned value.

When specifying PROPID_M_ARRIVEDTIME, you can set its Type Indicator to VT_NULL. When the Type Indicator is set to VT_NULL, MSMQ sets the VT field to the appropriate type indicator.

Microsoft provides several time functions you can use to manipulate the returned Coordinated Universal time value.

When reading messages from a journal queue, PROPID_M_ARRIVETIME indicates the time the original message arrived at its destination queue, not when the copy of the original message arrived in the queue journal.

When reading messages from machine journal or dead-letter queues, PROPID_M_ARRIVETIME indicates when the message reached the journal or dead-letter queue.

This example shows how PROPID_M_ARRIVEDTIME is specified in the MQMSGPROPSstructure.

	Copy Code
aMsgPropId[i] = PROPID_M_ARRIVEDTIME; // Property ID aMsgPropVar[i].vt = VT_UI4; // Type indicator aMsgPropVar[i].ulVal = dwArrivedTime; // Value i++;

Note:
OS versions prior to 2.12 require the MSMQ add-on pack.
