The minimum age of a connection, as used to determine the set of connections for which data is to be collected at the periodic intervals and/or when acctngFileCommand is set to 'collectNow'. The age of a connection is the elapsed time since it was last installed. When the periodic interval expires for a file or when acctngFileCommand is set to 'collectNow', accounting data is collected and stored in the file for each connection having a type matching acctngSelectionType and whose age at that time is greater than the value of acctngFileMinAge associated with the file. This value may be modified at any time.
