That would be page 67 of DNS & BIND 3rd Edition right ?

Yes, TTL is an unknown RR record type.

In bind 9 zone files, put a TTL directive ($TTL) in the top.

That is on the first line:

$TTL 86400

So, in general, the following lines could be on the top of your zone file:


  $TTL 86400          ; A TTL value of 1 day
  $ORIGIN 0.0.127.in-addr.arpa. 
  @    IN SOA xxx.xxx.com. root at xxx.xxx.com. ( 1 10800 3600 604800 86400 )
    	  NS  ns1.xxx.com.
	  NS  ns2.xxx.com.
  1  	  PTR localhost.
