TLV 5 indicates the time that the policy engine stopped processing this event. Processing time, in milliseconds, for the event can be calculated by subtracting the value of the Policy Exit Timestamp field with the value of the Policy Entry Timestamp field.
The Policy Exit Timestamp is obtained using the Java System.currentTimeMillis(), which is the number of milliseconds since January 1, 1970. For example, a value of 1309440504000 represents June 30, 2011 at 09:28:24.
