<para>The TTL in seconds for positive lookups. If a store path is
queried from a substituter, the result of the query will be cached
in the local disk cache database including some of the NAR
metadata. The default TTL is a month, setting a shorter TTL for
positive lookups can be useful for binary caches that have
frequent garbage collection, in which case having a more frequent
cache invalidation would prevent trying to pull the path again and
failing with a hash mismatch if the build isn't reproducible.
