That doesn't include "raw" DCF77 clocks. These clocks just generate
a series of pulses received through an AM antenna, and ntpd decodes
this. It just takes 90 seconds average at startup to get in sync
(0 to 60 seconds to sync with the beginning of a message, then 60
seconds to get a complete message).
