I have patched the kernel with the patch-o-matic, and any rules that I add show up in the iptables rules listing. However, no packets are matching the rules. I can create a rule that is identical to the TIME based rule, without the TIME constraint, and the rule matches fine. As soon as I add the "-m time" component to the rule, no more matching.
There has been some discussion about TIME in netfilter-devel, have a look at the mail archive.

Those changes are still pending to be applied to pom-ng.
