You need to add something like this abofe the SOA record:

$TTL 18000 ; Default TTL 5 hours

In recent BIND (8.2.0 and up IIRC) the TTL value within the SOA record is
is used for cached negative responses.  You might want to reset that to
one or two hours.  The default TTL is now specified in the $TTL statement
above the SOA record.
