We already have clients that don't want to do that, as they discard 
sub-minute resolution. But I take your point that some clients may want 
to do that and we should cater to this subclass of clients too. In that 
case, how about if we stick to at most 1-ms resolution in the data, and 
note in zic.8 that 1 ms resolution is the way to go? I say "1 ms" 
because of Steve Allen's email.
