Given the typical polling intervals that UNSYNC status may be valid
significantly longer than the actual leap second. That is why I think it's
wrong to set UNSYNC during leap second. It's also against expectations: Why
should an NTP server that is stable be UNSYNC or jump to stratum 16 suddenly?

This simply feels wrong.
