The question whether to merge the time module came up repeatedely
at netfilter workshops, but it was always decided against it so far,
mainly because it apparently can't deal with timezones and daylight
saving time. IIRC Harald had strong feelings about it, I personally
don't care much about this shortcoming as long as its documented.
I'm not even sure its correct since the kernel has sys_tz. So if
anyone finds out and submits a patch, I'll consider it.

As I stated multiple times, the reason why its not included is that
its horribly slow. But since I don't see any better way to do this
and I know quite a few people are using this, I would consider this
as well if someone sends me a patch, which has not happened so far.

It has been done in the past, but I deleted everything not included
upstream from iptables, mainly to avoid compatibilty breakage in
case we decide to merge something and the userspace API needs to
be changed (a lot of the old matches have 32/64 bit issues etc.)
