IIRC the newest 9.2 release candidates now complain, but insert a
default TTL if none is specified in the zone file,   which is what some
of the later bind 8s do as well.

(from the changelog)

 834.   [func]          Accept (but warn about) master files beginning
with an SOA record without an explicit TTL field and lacking a $TTL
directive, by using the SOA MINTTL as a default TTL.  This is for
backwards compatibility with old versions of BIND 8, which accepted such
files without warning although they are illegal according to RFC1035.
