Basically the 128ms, but one doesn't want to anywhere close to that 
128ms.  Note I said a few tens, which could be say 40-50.

I was replying to someone that said they only wanted time to 1 second 
and I was really pointing out that there can be time sources that would 
satisfy that requirement, but would be unsuitable for use with NTP, so 
by asking on an NTP newsgroup, they are effectively asking for times 
that are significantly better than 128ms.
