Re: time resolution (was Re: six-page binary format draft)
Our middle name is "Engineering". "Engineering" means solving a
problem economically, within a set of constraints. The trick, of
course, is knowing which constraints are reasonable and which aren't.
It's certainly possible to have machines' clocks agree to within a few
milliseconds. Is it necessary here? These are *certificates*, not
challenge/response values. I will, of course, point out that
certificates are used precisely so that full-time online operation
isn't necessary -- if I can query the authorization center when someone
presents me with credentials, I don't need the credentials to be
signed.
We don't need finer resolution than 1 second. I suspect we could stick
with 1 minute, if we wanted to save some space.
