I can suggest starting with something like this; note that sed -i
modifies the files *in place* so work on a spare copy and diff

sed -i~ -se 's/\/\/' \
-e "/^@[[:space:]]*[[:digit:]]*[[:space:]]*[A-Z]*[[:space:]]*/{ :l; /)/ ! {N; b l}; /)/ ! {s/.*/unterminated SOA\n&/;q3}; s/(\([[:space:]]*\)[0-9]*/\1`date +%Y%m%d`00/}" ZONEFILES
