This is a _should_, but there are situations where this is not
possible. A common case where ntp is not available at startup (and the
timeout delay _not_ appreciated) is when a complete machine park at an
ISP was shutdown (for example during move, power works or an
emergency) and is now re-started. The firewalls usually depend on the
NTP and DNS servers which they protect, so if you start the NTP
servers first, the firewalls are not there so there is nothing to sync
from, and when you start the firewalls first, the NTP servers are not
there so there is nothing to sync from again.
