Description:
systemd fails to set up timesyncd.service with the NTP server provided by DHCP as documented in the Wiki, Ref. https://wiki.archlinux.org/index.php/Systemd-timesyncd
I just tested this on systemd version 216-3 on x86_64
Installing NetworkManager does not fix this - should a separate bug be filed there as well?

Steps to reproduce:
Pristine base install, rebooted # Use ip link to retrieve interface name
dhcpcd -T enps0s25 # Observe ntp_servers stanza in response
systemctl start dhcpcd@enps0s25
timedatectl set-ntp true # Start NTP client
timedatectl # Confirm NTP is enabled and in sync
journalctl -f # Observe NTP on default time*.google.com
This task depends upon

Nothing to do in Arch -- please report this upstream. Either it's a bug, or the DHCP client (yet?) doesn't honor NTP options in the response.
