The way I've solved this in the past is to create a zone file template with "variables" in the text that are easy to find. EG:
[TIMESTAMP]
is where the number goes. All my zone files are managed by a script that parses the template files with values appropriate for each domain.

Hi all,
I have a set of dns zone text files in "bind" format. On the fourth
line there is a 10 digit timestamp (ignoring white space, the first
field). There is no way to predetermine the value so search and replace
by value is a no go and seems to require some positional approach such
as "line 4, first 10 digit field".
What is the easiest way to replace each of them with the same value,
$(date +%s) ?
My sed|awk foo is weak.
Any takers?
TIA,
Mike Wright
