Yes, it updates as I write on the zone file. What shocks me too is that
every while the zone file timestamp updates automatically I think due to
bind's strange beahaviour, my configuration is as follows, nothing
fancy:

options {
	listen-on { any; };
        directory "/var/cache/bind";
        query-source address 10.5.20.11 port 53;
        version "hidden";
	allow-notify { none; };
	allow-transfer { slaves-dmz; };
	transfer-source 10.5.20.11;
	allow-query { slaves-dmz; localhost; };
	forwarders { 10.5.20.12; 10.5.20.13; };
	forward only;
	transfers-in 100;
	recursion yes;
};
include "/etc/bind/dmz/zones";


Where "zones" is a file containing another 'include' statements with the
zone configuration of each domain like:

include "/etc/bind/zone1.conf";
include "/etc/bind/zone2.conf";
...
include "/etc/bind/zoneN.conf";


My server is chrooted and, otherwise everything else works fine.
