I've only seen messages about getting ntp information over a network (so far), and I'm not familiar with crypto/entropy gathering/ntp, so forgive me if I ask a stupid question, but does everyone also think about those systems which have a more or less precise clock attached (e.g. GPS or atomic clocks which sync the system clock via nptd)? And what are the numbers for this solution (for those people which are interested in numbers to be their own judge)?
