Re: Time-stamp server. TimePrecision info
It may be true that, out of a sense of fairness, some events are
considered "simultaneous" if they occur within the same second,
or minute. But 100 years ago, that may have been "days or weeks".
I see technology rocketing ahead so fast my head spins. Try, if
you can, to imagine processor speeds and typical transmission
bandwidths 1000 times greater than the fastest today. It will
not be too far off. So I must concur with those who ask "What
harm in allowing microseconds, or even nanoseconds, to be
representable in the protocol? We may not (yet) have many
applications where such resolution (in signatures, certs, and
authentication) is critical. But can the same be said for
"hours"? Generally, no.
Whatever you do, do not make a determination based upon saving
a few bytes. Such a decision will appear laughable in 10 years.
