Are there any situations where a firewall's acqusition of time
could/should be from a network time source? Not necessarily a public
source, it could be an "internal" time source.

It's a good idea to have the timestamps on logfiles consistant, so running ntpdate or some such upon system boot is a pretty good idea. Running ntpd against internal NTP servers is a greater risk; so if your systems keep adequate time, don't; if your systems drift noticably, then NTP will probably be worth the tradeoff.
