RE: correct way to set timezone & clock/date?

NTP doesn't connect to you, so you shouldn't need any special firewall rule.

Your system goes out and connects to the NTP server, and if you make this
system a server also, then
all the internal systems should connect to it, to set their time.

The internal network should be open to all systems, so all the clients
should be able to get the time.

Hmm, so I did the following:

# iptables -A input_ext -p tcp -m tcp --dport 123 -j ACCEPT

and then tried starting ntp services again but it still seems to hang when
trying to get the initial date and time. So adding a rule to the firewall
for tcp access on port 123 seems to have made no difference to my problem.

nuts...
