 Because NTP spoofing can be used to attack the node. GNSS spoofing is much
 harder: it would either require being in physical proximity of the target
 or being a clique of GNSS operators ready to make lot of collateral damage
 in order to attack the network. Of course we can use both GNSS and NTP and
 detect such attacks.
