Note that signature expiration times are used to protect from replay
attacks. If you are signing zones with expiration dates 28 years in the
future, you may want to consider if this is a good idea or not.
All signature expire times are in YYYYMMDDHHMMSS format in the zone data
and are handled correctly as far as BIND deals with it.
If your OS deals with the 2038 issue correctly, then BIND will as well.
I do also assume that there will be a few BIND releases between now and
then and that you will be upgrading accordingly.
