The Expire time specifies how long a slave server will continue to be
authoritative for the zone when it has been unable to contact the master
server for refreshes.  If it can't query the SOA record, or it sees a new
serial number but can't perform a zone transfer, for that length of time it
will start answering non-authoritatively for the zone.  It will still
answer with the data it got during the last successful transfer, but the
Authoritative Answer flag will not be set.
