It was.  It also was used for negative caching time and one other thing
that escapes me right now.  Now, it's just the negative caching time,
and $TTL tells what the default time-to-live is for entries in that file
(which is not a value that has to be stored in an RR).  This is all to
support the RFC requirements.
