shorten cache ttl?

Hello,

I couldn't try this yet.

This doesn't seem to work. In the BIND cache, there's a record that is 
at least 2 days old. I set max-cache-ttl to 86400 and restarted BIND, 
but the record still appeared, BIND didn't look for new records. Same 
when I set max-cache-ttl to 0. Are existing records in the cache treated 
different than new records? How can I clear the BIND cache? Another 
caching nameserver running djbdns already knows about the new records.
