They're independent implementations.

Which, as I understand it, is a descendent of ipchains.  ipchains is a
descendent of an older version of ipfw.

There's a lot of Linux-specific terminology in there, so I can't
really unwind it very well.  I don't know of any support for
time-of-day modifications, but I'd expect that somebody out there has
written it.  Depending on the exact requirements, it may even be
trivial.  "Connection helpers" sounds like automatic proxy support,
which I'm not crazy about but which I know ipfilter does somewhat more
extensively than ipfw.

The big advantage of ipfw is that dummynet(4) hooks in through it.
Dummynet is a traffic shaper, as well as a framework that sort of
resembles (as far as I understand) netfilter.

Also note that it's perfectly possible and often quite convenient to
use more than one firewall program...
