+/* SUMMARY
+/*	message delivery profiling
+/* SYNOPSIS
+/*	#include <msg_stats.h>
+/* DESCRIPTION
+/* .nf
+
+ /*
+  * System library.
+  */
+#include <sys/time.h>
+#include <time.h>

+  * External interface.
+  * 
+  * This structure contains the time stamps from various mail delivery stages,
+  * as well as the connection reuse count. The time stamps provide additional
+  * insight into the nature of performance bottle necks.
+  * 
+  * For convenience, we record absolute time stamps instead of time differences.
+  * This is because the decision of what numbers to subtract actually depends
+  * on program history. Since we prefer to compute time differences in one
+  * place, we postpone this task until the end, in log_adhoc().
+  * 
+  * A zero time stamp or reuse count means the information is not supplied.
+  * 
+  * Specifically, a zero active_arrival value means that the message did not
+  * reach the queue manager; and a zero agent_handoff time means that the
+  * queue manager did not give the message to a delivery agent.
+  * 
+  * Some network clients update the conn_setup_done value when connection setup
+  * fails or completes.
+  * 
+  * The deliver_done value is usually left at zero, which means use the wall
+  * clock time when reporting recipient status information. The exception is
+  * with delivery agents that can deliver multiple recipients in a single
+  * transaction. These agents explicitly update the deliver_done time stamp
+  * to ensure that multiple recipient records show the exact same delay
+  * values.
