If you do not like the X year limit at startup I recommend you lobby for
something more to your liking.

I think there are 2 places to lobby:

- Dave
- The IETF NTP WG

I believe Dave's point is that this is trivial to work around - one sets the
initial date to be either somewhere between the time the executable was
compiled and X years *later* - then ntpd starts up and sets the date
correctly.  In fact, it will do that for the next X+60ish (unless it's
X+30ish) years.

I would *love* to see the spec include a flag (could be the stratum, could
be something else) that says "The date you are being given is not X.Y
(seconds and fractions of seconds), but is X (all seconds)".  This will, I
believe, solve the problem without making the packets bigger.
