Do you mean a comment header or an SOA record?  Either way, I would
suggest a shell script using 'ex' and a "here document".

In doit.ksh:
#!/bin/ksh

# The following is off the top of my head, debug before running!

if [ "0" = "$#" ]; then
	echo "Syntax: $0 zone.file ..."
	exit 1
fi

today=`date "+%Y%m%d"`
mod=00
backdir=back.`date "+%Y%m%d.%H%M%S"`

mkdir "$backdir"

for i in "$@"; do
	case "$i" in
	  -[0-9])
	  	mod=0`expr "X$i" : 'X-\([0-9]\)'`
		continue
		;;

	  -[0-9][0-9])
	  	mod=`expr "X$i" : 'X-\([0-9][0-9]\)'`
		continue
		;;

	  *)
	  	;;
	esac
	if [ ! -f "$i" ]; then
		echo "${0}: No such file \"$i\"."
		continue
	fi
	cp -p "$i" "$backdir/$i"
	ex - "$i" << EndOfEdit
/^\([^;]*\)200[0-6][01][0-9][0-3][0-9][0-9][0-9]/s//\1${today}$mod/
wq!
EndOfEdit
done

Then run:

named$  doit.ksh zone.*
