Quote from the bind doc

The last field in the SOA is the negative caching TTL. This controls 
how long other servers will cache no-such-domain (NXDOMAIN) responses 
from you.

The $TTL directive at the top of the zone file (before the SOA) gives 
a default TTL for every RR without a specific TTL set.

RR stands for Resoures Records
