It's easy to duplicate.
ntpdate starts up this way:
NTPSERVERS="0.debian.pool.ntp.org 1.debian.pool.ntp.org
2.debian.pool.ntp.org 3.debian.pool.ntp.org"
/usr/sbin/ntpdate $NTPSERVERS

It makes 4 queries to each of 16 servers, for a total of 64 queries.
That takes about 9.5 seconds.
(A bit of overkill -- but that's the config in the ntpdate package.)

some of those distro configs are completely absurd.


At startup, ntpdate is invoked as a result of dhcp coming up or when
the network starts up, via a script in /etc/network/if-up.d/

Weird. Maybe you should have chrony come up before then, which would block the
port for ntpdate.
