Looking at the ntp-dev code, there are only two references to

#define	PEVNT_TAI	(16 | PEER_EVENT) /* TAI */

So your point is well taken, the value doesn't fit in the peer status
word, but in fact it is defined but not used as far as I can see,
arguing for its removal.  Dr. Mills may be able to shed more light.
