How Cisco represent Arp entry's aging time in SNMP MIB

Please see the screenshot for "sh ip arp". My question is how Cisco represent the aging time in SNMP MIB. Is there any cisco proprieatry MIB to represent the aging. I want find the latest arp entry from SNMP. I can't see any useful field in ipNetToMediaEntry, ipNetToPhysicalEntry and cInetNetToMediaEntry.
Not sure if cInetNetToMediaLastUpdated is related, but I have never get any snmpwalk result from this oid yet.
