I'm expecting that NTPv5 will include things like the timescale used by the timestamp, so as long as the systems agree on how to convert timescales if they are not the same between the client and server (hello, General Timestamp API) it will be OK if an NTPv4 or NTPv5 box talks to an NTPv5 box, as the V5 machines will handle timescale conversions and we can specify in the Standard that v4 boxes speak POSIX, so the machine running the "smear" must do a conversion.
I'll be talking about this a bit in my FOSDEM talk. And while there is much to appreciate about the half-cosine smear, one thing some folks *hate* about it is that time from these machines is wrong on both frequency *and* time, to varying degrees, throughout the day. -- Harlan Stenn <st...@ntp.org> http://networktimefoundation.org - be a member! _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
