The important thing to know is that NTP uses UDP rather than TCP.
E.g. machines from my university cannot use remote NTP servers because
all UDP traffic is filtered away (they do have local NTP server which
get synchronized with remote server, of course).
So you need "outbound UDP port 123" open (inbound is only if you want
other machines to be able to synchronize with yours).
