A clarification: are you talking about the protocol (NTP) or the 
implementation (ntpd), or both? I guess it is sensible for an 
implementation of NTP to "process" the leap bits only on those two days 
of the year leap seconds can occur, but the RFCs are a bit vague on 
that. They just talk about setting the bits on the day of insertion. But 
don't worry, I won't lose my sleep over this :)
