I did nslookup on 2.netbsd.pool.ntp.org and added four server lines to /etc/ntp.conf using those ips. I commented out the pool line and no error.

You can pass the -w flag to dhcpcd which makes dhcpcd wait until it is assigned an address, which would be the same time that it receives domain name servers from the domain_name_servers option.

You could also put a dhcpcd hook (see dhcpcd-run-hooks(8)) in /libexec/dhcpcd-hooks that runs ntpdate at the appropriate time.
