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). -- Pierre Beyssac pb@enst.fr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
