I think I have a compromise solution that saves the baby :-)

typedef timezone-enum {
  // TZ snapshot we have now
}

typedef timezone-name {
   type union {
      type timezone-enum;
      type string;
   }
}


1) The NETMOD WG would maintain this module, not IANA.
2) The snapshot would be updated at long-term intervals, such as every 2
years

This forces the server to support a set of values the client can predict
and also supports extra strings not in the snapshot.  This prevents false
negatives
wrt/ YANG validation, but not false positives (i.e., values have been
removed
from the snapshot).

Do timezone names get removed from the database? IMO, this seems rare
enough not to worry about until the next YANG snapshot RFC is published
with the now obsolete enums.
