problem with expire patch

I have compiled 2.6.12 kernel with iptables expire support, I also have recompiled iptables with expire support.
And I encounter a strange problem with time

xxx:/home/digis#modprobe ipt_expire xxx:/home/digis#/usr/local/sbin/iptables -t nat -A POSTROUTING -m expire --expiration +30 -o eth1 -j MASQUERADE

Then I wait more than 30 seconds....

xxx:/home/digis#/usr/local/sbin/iptables -t nat -L Chain PREROUTING (policy ACCEPT)

Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- anywhere anywhere expires in
-2s

and it keeps counting...
What I am doing wrong?
