I use unbound on all my servers listening only on the localhost, not 
sure if it needs the current time to be accurate when it starts or not 
but it never seems to be an issue.

I'm of the opinion every server should have locally provided DNSSEC 
enforcing DNS services simply because it takes away a potential attack 
vector to have local DNS queries stay local.
